Love it! sorry again! from PIL import Image One note though, pip3 isnt always installed, so I suggest adding the sudo apt install python3-pip command before entering the sudo pip3 command. I get the same error. Edit the example python script using a text editor and make the change as described in the Screen Size Adjustment section. Just got the OLED display working using the info above. Consider being a bit more detailed and assume that those reading do not have the same initial conditions that you do. I used psutil and netifaces to get my data. Is there a way to have the display turn off/clear when the Pi is shutdown? **** At this point it the OLED should now show its display **** It also means your Python script doesnt need to convert them. To install the library we will clone the Adafruit git repository. Is it possible to have the Disk line Scroll and show each after another or switch between on and another? You dont want to short a connection or plug a lead into the incorrect pin by mistake and not have a chance to check your connection before powering it up. sudo apt update zipfile.BadZipfile: File is not a zip file. Save my name, email, and website in this browser for the next time I comment. Ive got an OLED display that displays in blue/yellow its also based on the 1306. We can play around with the spacing, but this font is just not great for this stats layout. File /home/pi/Adafruit_Python_SSD1306/ez_setup.py, line 88, in archive_context Thanks again :), 2 years ago 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. please help! RPiOS Bullseye. I was wondering where I would be able to change the GPIO pins as I want to set my relais there (respectively the setup forsees so). I love tinkering with electronics, making, fixing, and building - I'm always looking for new projects and exciting DIY ideas. I seem to remember making some changes to the list of package installs due to a change in the PIL package. There is very little info regarding these little screens beyond setting them up. Have you built it into your own case? import os I just received my case a few days ago and have everything set up now. use_setuptools() /facepalm, of course it shows after I posted again. Make sure that your Pi is off and the power is disconnected before plugging or unplugging jumpers from the GPIO pins. Any ideas ?? #show display content for 2 seconds I leave this here just in case someone else experiencing the same problem , Thanks for your work again. >>> %Run stats.py. Is it possible to add the name of the server alone with the status to display? difficult & clueless I am. sudo python3 -m pip install upgrade pip setuptools wheel I tried to get it work for hours with the official tutorial of the screen, but it was far to complicated and didnt work. Ive noticed on your video when yours boots up it does show numbers and shortly after switches to the IP address. 
Ive just used this guide on a project and have made some updates. Make the change and then save/quit using CTRL-X, Y then ENTER.
I prefer using GIMP because it is free. I have a problem while installing the python library. It is not calculated in this script, this script just fetches the data from the OS. I am having a trouble! is it possible to set up 2 oled display on a Pi Zero? I am in same boat. Thank you again for a great tutorial and for the amazing case! Traceback (most recent call last): I have never tried to do so, but you can set the script to display any metrics that are made available by other applications. I think you can get 2 x 8 channel multiplexers to 16 screens working. but still this program does not run at startup!
disp.display() Great Job. They are available in various sizes but common sizes include 12832 and 12864 pixels.
After buying the kit from you I am amazed.
File /usr/lib/python2.7/zipfile.py, line 813, in _RealGetContents Ive just resolved it by running pip3 install Adafruit-BBIO just a guess.
I havent seen those packages come up previously, what operating system/version are you running? on Introduction. Plug SCL (mine is purple) into Pin 5 and SDA (mine is white) into Pin 3. raise BadZipfile, File is not a zip file Great write up! Hi Michael, Just a quick question: How to Show different Disks?
Run the bellow command on terminal: Scroll down, and just before the exit 0 line, enter the following: Did you make this project? return self.gen.next() Ive tweaked the code, fixed indentation erros and now it seems to be working! This script will continue to run and update the display as long as youve got your IDE open. I resolved it by changing to the directory of the script before running it in cron. Try either relocating both the script and font into the default directory /home/pi/ or rather use the default font. I then put the SD card into my Pi3 and it did detected the screen plus the examples straight away.
Next, we need to connect the communication jumpers SCL and SDA, which just get plugged into the corresponding GPIO pins. 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. Running the script you can now see that the characters are gone and the temperature is being displayed alongside the CPU load: This is where I left the display in my original video, but it looks a lot better if you use a better font, which allows the text to fit into the width limit and uses the full height of the display, so lets look at that next.

In this tutorial Ill explain how I setup my0.96 OLED display module using the Pis I2C interface. The cheaper ones have single colour pixels that are either white, yellow or blue. Next lets have a look at the python script and how to install it. Are the four module connections correct?
Question I get the following error: i am hitting the same wall Thanks.
File /home/pi/.local/lib/python3.7/site-packages/PIL/ImageFont.py, line 853, in truetype 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. draw.text((x, top+8), str(CPU), font=font, fill=255) You may already have them installed, but its worth checking. sudo apt-get install python3-pip
One question would I be able to display pi-hole stats? This is a quick modification I made. How would I make an image that makes use of both of those colours? If your screen isnt working you should start at the beginning of this tutorial and work through it. Greetings, https://github.com/adafruit/Adafruit_Python_SSD1306/issues/22. 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. If I add the script in the crontab and reboot, the display flashes up and goes blank. without being able to see your code, Id say that youve probably made some syntax errors. I would like to ask you if I am allowed to post that remix over at thingiverse.
I changed the apostrophe to a degree symbol. Regarding my last post, about a problem connecting with i2c to the display I found that one of my breadboard wires was not conducting. By default the image.py example will convert the image to 1-bit but it assumes the resolution is correct. With the dtoverlay the numbers are GPIO references not physical pin numbers. Did some googling around but could not get this to resolve Any ideas? So you tried image.py example and wondered how you can create your own images? I prefer creating pbm files as they are black and white and much smaller files. Please see theChange Raspberry Pi I2C Bus Speed post .
Hello! Make sure that the python version you choose here matches the version you are going to run the actual script in. 
There is only 1 other 3.3V pin and that is pin 17. Thanks for detailed instructions! >>> %Run stats.py self._RealGetContents() Check all of your connections again and youre then ready to power your Pi up and get started with programming the display. sudo apt-get install python-smbus Ive got no idea why the device PCB suggests the address is 0x78 when it is clearly 0x3c.
** You can connect the Gnd pin to either Pin 6, 9, 14 , 20, 25, 30, 34 or 39 as they all provide Ground. Ive found this happens from time to time on my Pis as well. I have no idea where it comes from. Shift 0x3C to left by 1 gives you 0x78 (and obviously vise versa). sudo apt-get install i2c-tools If you now run the script youll see that the text is a bit taller and is in your new font, but its still bunched up at the top of the display. draw.text((x, top), IP: + str(IP), font=font, fill=255) Is the screen compatible with the Raspberry Pi Zero? However if i run python3 stats.py directly from the examples folder it works.. So I would imagine you could pull data from pi-hole if you wanted to. It showed the device had been detected with an address of 0x3c. sudo python -m pip install upgrade pip setuptools wheel
git clone https://github.com/adafruit/Adafruit_Python_SSD1306.git all as one string, but did run them separate after since I got an error. Everything went well according to the tutorial, except for the display programming.
It has four pins. Once completes navigate to the librarys directory: In this folder you should find example script: By default it shows memory usage, disk usage, CPU load and ip address. draw.text((x, top+8), str(CPU), font=font, fill=255) Notify me of follow-up comments by email. I also checked the syslog and it says that the cronjob was runned but still a black display. I'm sure it has something to do with me not understanding the '$NF==' stuff, any tips would be appreciated! If your screen is using an address other than 0x3c did you adjust the Python script. Hi Pascal, Hopefully it works for you. This display is actually a 128 x 64 display, not the 128 x 32 display which is set by default. How can I solve this? python3-dev should already be installed in the latest Raspbian image. So the display is receiving two sets of commands from two different scripts, thats why it looks like it is going crazy. Thank you very much for your projects and keep the ideas coming. Thanks so much for making this follow up tutorial because I was having a little bit of trouble using the original one you created. I am in the process of assembling a webserver to a rural school. Thanks for the feedback Matthew. I really enjoyed this project, making the case and getting the display functioning.
This site is not associated with the official Raspberrypi.org site or the Raspberry Pi Foundation. Hi Alexander, In your case, I would think that this crontab line should work: @reboot cd /home/pi/Adafruit_Python_SSD1306/examples; python3 /home/pi/Adafruit_Python_SSD1306/examples/stats.py &, Thank you very much for this instruction and fun little project. I use user pi for logon and the entry in crontab is exactly as described in the 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. Hi Ivan, you can get an I2C multiplexer to add 8 screens. To get the display to show our Raspberry Pis performance stats, were going to be running a Python script. It should be possible, but you would need a screen that allowed you to change the default I2C address. ls 0x3c is these 7 bits 111100 but once the R/W bit is included it becomes these 8 bits 1111000 which is 0x78. thanks for the great Case and your work with all those detailed tutorials. File setup.py, line 4, in It looks like its not able to find the font youre using within the folder youre running the script from. 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). You could also try using one of the GPIO pins to switch the power to the display on or off. Luckily i found this Tutorial, it saved me from a lot of wasted time <3. Traceback (most recent call last): Ive just Googled it and understand now. I keep getting a lot of weird characters all the time. ive the exact same problem but with an 12864 and i cant see the solution, Just found the solution after commenting -.-, https://stackoverflow.com/questions/37016946/remove-b-character-do-in-front-of-a-string-literal-in-python-3, you need to decode the string you want to display as utf-8. The I2C interface is disabled by default so you need to enable it. But if i compare it to the RaspiOS Buster panel usage monoitor it should give you arround 4 7% in idle. https://github.com/adafruit/Adafruit_Python_SSD13 Arduino Robotic Arm Controlled by Touch Interface. Nice tutorial. Share it with us! if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[250,250],'the_diy_life_com-medrectangle-4','ezslot_10',174,'0','0'])};if(typeof __ez_fad_position!='undefined'){__ez_fad_position('div-gpt-ad-the_diy_life_com-medrectangle-4-0')}; These displays dont have reverse polarity protection, so if you connect them incorrectly (even just once) then its quite likely that theyll be damaged and will no longer work, even if you correct the wiring afterward. 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. would you able to solve the platform issues? The string "cmd = "hostname -I |cut -f 2 -d ' '"" doesn't work - no IP is displayed. 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.
draw.text((x, top), "IP: " + str(wifiip), font=font, fill=255) draw.text((x, top+10), "CPU Load: " + str(CPU_LOAD) + "%" , font=font, fill=255) draw.text((x, top+20), "Disk: " + str(usedgb) + "/" +str(totalgb) + " " + str(diskused)+ "%" , font=font, fill=255) draw.text((x, top+30), "CPU freq: " + str(CPU_freq), font=font, fill=255) draw.text((x, top+40), "Mem: " + str(usedmem)+ "/"+ str(totalmem), font=font, fill=255). You can see the text isnt that clear, there are a few weird characters on the display and the CPU temperature isnt displayed. Hi Thanks for posting this tutorial, i am getting errors and wondered if you could help: File "stats.py", line 47, in
To install the library we will clone the Adafruit git repository. It works via I2C so should work just fine on the Pi Zero. Awesome! These are most commonly GND, VCC, SCL, and SDA. Yes you can change the script to display any metrics available via the shell scripts. draw.text((x, top+16), str(MemUsage), font=font, fill=255) Once youve booted up your Pi, you should be on the Raspberry Pi OS desktop. My OLEDdisplay module is a 0.96 I2C IIC SPI Serial 128X64 OLED LCD LED Display Module. time.sleep(2), #Clear Display but I get RuntimeError: Could not determine platform.. Raspberry Pi is a trademark of the Raspberry Pi Foundation. but when I updated raspbian, there is no longer anything shown on the display by default. Then again, I read something about a BUS and that I could control different interfaces with sam pins ughhh. This was good news as it showed the device had been detected with an address of 0x3c. Im new to the world of R-PI and was extremely excited when cases arrived today. Thats great, thanks for the feedback Luigi! I was wondering if you would know why when using this i2c screen it seems to effect my ability to also use a DS18B20 temperature sensor? I had to change my strip by adding, # Added by Gene Adafruit use ppm as the library also supports their colour OLED modules. This has been a really helpful tutorial. Dont just copy this arrangement though, make sure you check your own display as there are versions of this display that have the VCC and GND pins the other way around. This is the default hex address for this type of device. Would you please tell me? disp.image(image) Navigate into the examples directory : In there you should find a number of example scripts such as : The examples should give you screens that appear in the examples below : By modifying these scripts you can create your own graphics with shapes, images and text depending on your project. Used this and it works everytime: "sudo python /home/pi/stats.py &" starts to work after replacing "python" to "python3" and put this script to /home/pi/ directory. Ill get this step added to the guide as well. OSError: cannot open resource. Once setup it is easy to use Python to place text, draw shapes or even display simple images and animations. 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. Unfortunately no easy solution is available as the Pi only has the temperature available in celsius. Plug your ribbon cable into these pins and then make a note of which colour youve got connected to which of the four pins. cd Adafruit_python_SSD1306/
Sorry if I wasted your time thinking about my post. I built a case similar to your design but using 3/16 plexiglass. on Step 5. Comment out the line near the top which sets the display size to 128 x 32: And then uncomment the line which sets the display size to 128 x 64:if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[300,250],'the_diy_life_com-large-mobile-banner-2','ezslot_15',178,'0','0'])};if(typeof __ez_fad_position!='undefined'){__ez_fad_position('div-gpt-ad-the_diy_life_com-large-mobile-banner-2-0')}; If you run the script youll now see that the text is much clearer, but it all bunched up in the top half. Thank you for sharing this great information! I followed their wiki to get it fired up but I am not a programmer.
