I would like to really thank you for this nice case. return freetype(font) You can do this by typing in the following command: You should then see a table, similar to the below, that shows a single pair of characters in it. cd examples Copy these two portions of the script below and paste them into your script on your Pi. First time connect any non USB device with raspberry pi.
Heres how I did it if anyone is wondering: Insert: new_temp = str(temp[0:2], utf-8) + +C Python is sensitive to the indentation of each line, so Ive youve modified these in any way, then the lines might not be functioning as expected. draw.text((x, top+16), str(MemUsage), font=font, fill=255) I keep getting a lot of weird characters all the time. I wanted to know how to display 2 Pages with different informations in first. Love it! HEy very straight forward and easy to do. Thanks for the update Pascal, happy to hear youve managed to get it working correctly. Hello, Followed this and almost got it working only issue I am presented with is right at the end. I built a case similar to your design but using 3/16 plexiglass. Share it with us! The following lines will be added to show CPU temperature on OLED display module: Below code was modified accordingly to remove 'b' character from the OLED display. Nice tutorial. Go back and re-check your connections to your Pi and display and re-check that youve got I2C communication enabled after a reboot. Is it possible to add the name of the server alone with the status to display? Thank you again for a great tutorial and for the amazing case! Thanks nevertheless for the fantastic tutorial ..

I use this script on my Raspberry Pi Desktop Case and a lot of people have asked me for some more in-depth setup and programming instructions to get it running. from PIL import Image Thanks so much for making this follow up tutorial because I was having a little bit of trouble using the original one you created.
Ive noticed on your video when yours boots up it does show numbers and shortly after switches to the IP address.
I cant see where these added characters are coming from. I think you have to install more libraries if using Raspbian Lite. I seem to remember making some changes to the list of package installs due to a change in the PIL package. Check all of your connections again and youre then ready to power your Pi up and get started with programming the display. ls (Should show a DIR containing setup.py in it) Thanks for the tip Arik, Ive got an OLED display that displays in blue/yellow its also based on the 1306. draw.text((x, top), IP: + str(IP), font=font, fill=255) Last year Seeed Studios launched the reTerminal, a Raspberry Pi Compute Module 4 based touch display terminal with a pretty good list of features. A while ago I did a bit of an experiment to compare the sound level between TMC2208 and A4988 stepper motor drivers. sorry again! Also everything i tried after the first time we edit stats.py, changing to 64 lines, etc doesnt work. File /home/pi/Adafruit_Python_SSD1306/examples/stats.py, line 71, in Before detecting the OLED, when I run the following in cmd: It returns a serial number (28-xxxx).
Make sure that your Pi is off and the power is disconnected before plugging or unplugging jumpers from the GPIO pins. The script is one of the example scripts provided in the Adafruit Python SSD1306 library, with some tweaks. Hi Alexander, I am in the process of assembling a webserver to a rural school.
Works great! Did some googling around but could not get this to resolve Any ideas? Youll notice in the script an alternative line which resizes and converts an image so you can load images without worrying about their size and colour. 1 year ago, install the module:sudo pip3 install Adafruit_BBIO, Nice write up. File /home/pi/Adafruit_Python_SSD1306/examples/stats.py, line 103, in Assuming I set up the second software I2C using the steps above, how do I then point the second script to run on the second OLED? We hope to help everyone get the most out of their Pi by providing clear, simple articles on configuring, programming and operating it. it should spell sudo apt-get upgrade and not ugrade. import os I changed the apostrophe to a degree symbol. The colours on the cable dont matter, theyre just there to help you keep track of which wire goes to which terminal. Dont get confused between the GPIO numbers and the Pin numbers, ignore the GPIO numbers on the diagram and just go by the SDA and SCL labels and the corresponding pin numbers. Do the scripts default to run on y 1 / 0x3c, and its just a case of manually editing the script to look for the new device? Below are the connections of OLED module with Raspberry Pi 4 Model B: The I2C interface is disabled by default so you need to enable it. I used psutil and netifaces to get my data. I am in same boat. Regarding my last post, about a problem connecting with i2c to the display I found that one of my breadboard wires was not conducting. >>> %Run stats.py
There is very little info regarding these little screens beyond setting them up. Hopefully it works for you. Loved this whole project. Resizing and converting takes extra processing time so in high performance applications you are better feeding the script images that have already been resized. Pip3 V Question hi Michael, Great tutorial on building and configuring the OLED. Download the font PixelOperator.ttf from https://www.dafont.com/pixel-operator.font and then unzip the contents of the download. Alternatively, I did try it from the home screen as describe in your instructions and it still did not work. I have no idea where it comes from. So the display is receiving two sets of commands from two different scripts, thats why it looks like it is going crazy. They still run with a 12864 pixel screen but it is better to change them before you move onto anything more complicated.

Love this case by the way! One question would I be able to display pi-hole stats? I am having this same error as well! If you dont have a colour screen you can switch to pbm or png. Ran into a few issues but nothing a quick google search did not resolve!!! Ive just used this guide on a project and have made some updates.
This script will continue to run and update the display as long as youve got your IDE open. My OLEDdisplay module is a 0.96 I2C IIC SPI Serial 128X64 OLED LCD LED Display Module. Thanks for also the small additions and changes to layout and change the font! About: I am a hardcore robotics and IoT enthusiast. disp.display() at first following your step, everything worked totally fine!
However Ive never tried this myself. 23 days ago I get the following error: after doing some research I was able to fix this. Awesome! https://learn.adafruit.com/monochrome-oled-breakou https://circuitdigest.com/microcontroller-projects/ssd1306-oled-display-with-raspberry-pi. How would I make an image that makes use of both of those colours? dtoverlay=i2c-gpio,i2c_gpio_sda=5,i2c_gpio_scl=6 Fantastic tutorial. See if you can guess which ones were photos I downloaded to my Pi from Google Images! Hi Michael,
It will be slightly modified in order to get rid of the b-prefix and add CPU temperature of Raspberry Pi 4 Model B as well. zero pi raspberry options mmdvm case c4labs 1s jrz lonestar simplex heatsink zumspot aluminum sizes If you do too, grab a cup of coffee and settle in, I'm happy to have you here. os.chdir(/home/pi/Adafruit_Python_SSD1306/examples). If you get a table full of characters then youve probably made a wiring mistake as this happens if SDA is shorted to ground. And I really appreciate that you made a new Video and new Post about it because I had trouble to get the font displayed correctly. the screen worked immediately. Open up the examples folder in the Adafruit library which you were working on in the previous step and use the Thonny Python IDE to open up the stats script so that you can edit it. Just a quick question: How to Show different Disks? I immediately got started using your tutorial and I have to say that everything worked great with the exception for the final step. Hello,
We can play around with the spacing, but this font is just not great for this stats layout. I use user pi for logon and the entry in crontab is exactly as described in the tutorial??? As mentioned running all the previous commands were accepted and worked. After I connect the i2c screen it seems to replace the temp sensor replaced with a set of DS18b20 unrelated serial numbers Any thoughts on whats going on would be greatly appreciated! In crontab after I try to exit it says File name to write: /tmp/crontab.LfxgzD/crontab and it gives me a bunch of options but you never said which one to do. The Adafruit examples assume you have a 12832 screen. I could not try it out until now, but I definitly will. To install the library we will clone the Adafruit git repository. The following libraries may already be installed but run these commands anyway to make sure : If you are using Python 2 then use these commands instead : I would recommend using Python 3 unless you have a really good reason for using Python 2. Comment out the line which loads the default font: Uncomment the line which loads the replacement font and paste your filename into it, keeping the inverted commas on either side. This is the default hex address for this type of device. If your screen isnt working you should start at the beginning of this tutorial and work through it. Slowly getting more familiar with my raspberry pi as its my first encounter but not TOO familiar yet. You can see the text isnt that clear, there are a few weird characters on the display and the CPU temperature isnt displayed. The following steps are done on the Raspberry Pi OS desktop and edits to the script are made in Thonny Python IDE (which comes pre-installed). Ill get this step added to the guide as well. Youd probably have to run a pkill command to stop the current script and then run another script to blank out the display. Youve got a few options for the GND and VCC jumpers. Ive only ever seen the different colours at the top and bottom of the screens. Ive got no idea why the device PCB suggests the address is 0x78 when it is clearly 0x3c. Copyright 2022 - All Rights Reserved - Matt Hawkins. If i run the python script from the home directory To get the display to show our Raspberry Pis performance stats, were going to be running a Python script. I love tinkering with electronics, making, fixing, and building - I'm always looking for new projects and exciting DIY ideas. Its probably my fault because I opted to use a direct path to the stats.py file in the example folder rather than placing it and the font file on my desktop. My device has white pixels and uses an I2C interface which only requires four wires to be connected to the Pi. After buying the kit from you I am amazed. Like a mounted USB disk? Youll then need to copy the filename of your font, along with the extension, to put into the script. oled spi iic 5v 3v To do this simply edit the scripts and disable the 12832 config line by placing a # character at the front, and enable the 12864 line by deleting the # character from the front.
The fastest and easiest way is to put it in /etc/rc.local. sudo apt install libtiff5. sudo python 3 setup.py install File /home/pi/.local/lib/python3.7/site-packages/PIL/ImageFont.py, line 210, in __init__ Is it possible to have the Disk line Scroll and show each after another or switch between on and another? I wont lie I did run sudo python -m pip install upgrade pip setuptools wheel (DS18b20 connects to BCM 4 using the One-Wire (w1) protocol). Everything went well according to the tutorial, except for the display programming. In this tutorial Ill explain how to setup 0.96 inch OLED display module for showing system information of Raspberry Pi 4 Model B using its I2C interface. The cheaper ones have single colour pixels that are either white, yellow or blue. Delete your Crontab file and create a new one, or just replace the existing one.
This has been a really helpful tutorial. File monitor.py, line 26, in Type above and press Enter to search. The price you pay is the same. >>>>>AT THIS POINT I COPIED TGE REPLACEMENT stats.py OVER via WinSCP<<<<<< Replace the following lines in the # Write two lines of text section. It would be terrific for you folks to offer everyone a script/instruction to use this little beauty for a multi color Pi stats display!! Quick question, Is there a way to display temp in Farenheit and not celsius? There is only 1 other 3.3V pin and that is pin 17. The behaviour of the screen is probably because the script is running in the background already on startup and you are then running it a second time in your IDE. We had the screen working great on RPI OS. # Added by Gene I just received my case a few days ago and have everything set up now. The only problem I have is that the IP address doesnt show the IP, just a set of numbers with a letter before the end.
A note - You are making some assumptions that will leave others on a fresh system with errors. I2C allows multiple devices on the same bus as long as you can give each device a unique ID. I then put the SD card into my Pi3 and it did detected the screen plus the examples straight away. OSError: cannot open resource. After doing every step by step initially on the zero it wouldnt show up on the oled detect command. is it possible to set up 2 oled display on a Pi Zero? Then if i follow the last steps and have the script run on boot, will it auto turn on? I am noob here. 
Hi Thanks for posting this tutorial, i am getting errors and wondered if you could help: File "stats.py", line 47, in 
It showed the device had been detected with an address of 0x3c. Run each one of these commands individually in your terminal: Once youve done that then you can check that your Pi is able to see that your display is connected. I think you can get 2 x 8 channel multiplexers to 16 screens working. /facepalm, of course it shows after I posted again.
Those are fine but youll need to follow a different tutorial to use that style. Probably you are running it form a sub directory in your home folder and not your home folder itself. sudo python -m pip install upgrade pip setuptools wheel
File /home/pi/Adafruit_Python_SSD1306/ez_setup.py, line 128, in use_setuptools
I followed their wiki to get it fired up but I am not a programmer. Consider being a bit more detailed and assume that those reading do not have the same initial conditions that you do. sudo apt-get install i2c-tools It has four pins. 1 year ago, I m having this problem: please someone help me:OSError: [Errno 121] Remote I/O errorMy i2cdetect -y 0 output:0 1 2 3 4 5 6 7 8 9 a b c d e f00: -- -- -- -- -- -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- -- -- -- -- -- -- 3c -- -- -- 40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 70: -- -- -- -- -- -- -- --, Hi there, thank you for this.I wanted to add another line showing disk space on my mounted USB. Thats great, glad you like it!
If you are displaying multiple images per second it is worth increasing the bus speed of the interface as it can improve performance. To do this, youll need a 4 wire female to female jumper cable.
Thank you for the helpful tutorial. 
In this tutorial Ill explain how I setup my0.96 OLED display module using the Pis I2C interface. I would like to ask you if I am allowed to post that remix over at thingiverse. I also checked the syslog and it says that the cronjob was runned but still a black display. Hopefully they will resolve it soon. Make sure that the python version you choose here matches the version you are going to run the actual script in. Michael.
Again, as I mentioned, I did try @reboot python3 /home/pi/stats.py & and placed the two files on the home screen, but it still did not work. pip3 install pillow Thank you very much for your projects and keep the ideas coming. The header may need to be soldered on before you can use it. I'm sure it has something to do with me not understanding the '$NF==' stuff, any tips would be appreciated! The info and path I entered and saved in the crontab file was @reboot python3 /home/pi/Adafruit_Python_SSD1306/examples/stats.py & . !! Is there a way to have the display turn off/clear when the Pi is shutdown? had no issue installing.Getting the data was done in another way. I tried to get it work for hours with the official tutorial of the screen, but it was far to complicated and didnt work. You can do this within the raspi-config tool on the command line by running : For additional details on this step please see my how toEnable the I2C Interface on the Raspberry Pi post. im very new at all of this but followed along and all is working well. Youd need to convert the text to a number and then do the conversion before converting it back to text to display. ni.ifaddresses('eth0')wifiip = ni.ifaddresses('eth0')[ni.AF_INET][0]['addr']while True: #Get disk usage dict(psutil.disk_usage('/')._asdict()) totalgb = int(psutil.disk_usage('/').total / 1000000000) usedgb = int(psutil.disk_usage('/').used / 1000000000) diskused = psutil.disk_usage('/').percent #Get memory usage dict(psutil.virtual_memory()._asdict()) totalmem = int((psutil.virtual_memory().total / 1000000)) usedmem = int((psutil.virtual_memory().available / 1000000)) dict(psutil.cpu_freq()._asdict()) CPU_LOAD = psutil.cpu_percent(interval=0.0, percpu=False) CPU_freq = int(psutil.cpu_freq().current) # Draw a black filled box to clear the image. disp.image(image) The section in the script should now look like this : This step becomes essential if you want to start creating your own images to display on the screen. ImportError: No module named PIL. I check whether anything in crontab has been changed, but there was all okay as per your instruction. But we want it to run all the time and run on startup, so theres one last thing to do.
There is more information available through the link provided above this section https://unix.stackexchange.com/questions/119126/command-to-display-memory-usage-disk-usage-and-cpu-load. As a noob to Raspberry Pis I am still learning about programming and how to use the Pi. I plug the VCC jumper (mine is blue) into Pin 1, which is a 3.3V power pin.
Traceback (most recent call last):
Is there a way to reverse actions and start over?
oled amoled Once I installed the following two packages worked perfectly. So i2c_gpio_sda=5 means GPIO5, physical pin 29. Once youve booted up your Pi, you should be on the Raspberry Pi OS desktop. https://github.com/adafruit/Adafruit_Python_SSD13 Arduino Robotic Arm Controlled by Touch Interface. I have never tried to do so, but you can set the script to display any metrics that are made available by other applications. and library does not install. on Introduction. Hi Pascal, Hi Ivan, you can get an I2C multiplexer to add 8 screens. Plug SCL (mine is purple) into Pin 5 and SDA (mine is white) into Pin 3. Did you manage to move from this step? Here are some thing to consider : These screens are available from a number of retailers so take a look and pick one that is convenient for your location : Read the descriptions carefully as some OLEDdisplay modules use the SPI interface rather than I2C. Traceback (most recent call last): Thanks again :), 2 years ago So I made a remix of your case because I am more a fan of round edges. File /home/pi/.local/lib/python3.7/site-packages/PIL/ImageFont.py, line 850, in freetype Did you get SDA and SCL mixed up?
By default the image.py example will convert the image to 1-bit but it assumes the resolution is correct. This guide is written specifically for a Raspberry Pi 4B running Raspberry Pi OS Buster, although you should be able to work through it for other Raspberry Pi models.
It looks like its not able to find the font youre using within the folder youre running the script from. What do you think about it? Best regards, sudo python3 -m pip install upgrade pip setuptools wheel I connected them directly to the Raspberry Pis GPIO header using the following scheme : * You can connect the Vcc pin to either Pin 1 or 17 as they both provide 3.3V. sudo nano shapes.py draw.text((x, top+25), str(Disk), font=font, fill=255), # Display image. If youre installing the display into your case before connecting it then its a good idea to write down which colour is connected to which pin so that you dont forget. Thanks
I had to change my strip by adding, # Added by Gene on Step 5. Ensure git is installed by running : Then clone the repository using the following command : Once that completes navigate to the librarys directory : This process will give you ability to include the library within your own Python scripts. So the display stays black after a reboot until I run the python3 stats.py manually. So the last thing we need to do is adjust the layout.if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[250,250],'the_diy_life_com-leader-3','ezslot_17',179,'0','0'])};if(typeof __ez_fad_position!='undefined'){__ez_fad_position('div-gpt-ad-the_diy_life_com-leader-3-0')}; Adjusting the layout is a bit of a guessing game until you get it looking the way youd like it to, or just copy the numbers Ive used: When youre done, you should now have a clear OLED stats display running on your Pi. if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[250,250],'the_diy_life_com-box-4','ezslot_8',170,'0','0'])};if(typeof __ez_fad_position!='undefined'){__ez_fad_position('div-gpt-ad-the_diy_life_com-box-4-0')};Next, you need to plug the other ends of the jumpers into your Raspberry Pis GPIO pins. Next lets have a look at the python script and how to install it. You have entered an incorrect email address! The OLED displays pins are labeled on the front, which seems to confuse a lot of people, especially when theyve installed the display into a case or housing and the front area above the screen is no longer visible. You could also try using one of the GPIO pins to switch the power to the display on or off. Next, we need to connect the communication jumpers SCL and SDA, which just get plugged into the corresponding GPIO pins. But if i compare it to the RaspiOS Buster panel usage monoitor it should give you arround 4 7% in idle. Finally, you should see something similar to the following output on OLED display: You can easily make it so this program runs every time you boot your Raspberry Pi. Copy the OLED stats display script and the font into your home directory. Nonetheless, I cannot get the script to auto run upon reboot. Also dont forget the & at the end to tell the Pi to continue starting up and run the script in the background. Python3 stats.py Save the file when you exit and then try rebooting your Pi to see if it is working correctly. I checked everything! Also, b-prefix in front of each strings can be seen.
