2 months ago Thanks to much of what's posted here an other threads, I have the UCTRONICS OLED screen running properly on Ubuntu Server 22.04.4 LTS. One of the issues I am having is with the POWER BUTTON. I cannot seem to get it working while running the Desktop Environment (GNOME). Does the power button only function while running outside the DE?
This is a quick write up to get the OLED's working for those who are using Ubuntu Server 22.04.3 LTS as the instructions provided from UCTRONICS are specific to Pi OS.
Note that I've not got the Pi's to work with the shutdown button using aftermarket PoE hats. This will come later and I'll edit this post when I find it.
Steps to set up Pi Rack Pro OLED Ubuntu 22.04.3 LTS
Install raspi-config sudo apt install raspi-config
enable i2c sudo raspi-config Select 3. Interface Options and press enter Select I5. Enable/Disable automatic loading of I2C kernel module and press enter Select Yes Select Finish
Add all of the following to the /boot/firmware/config.txt
Add all of the following to the /boot/firmware/config.txt under the second [all] section, and place a # in front of "dtparam=audio=on" to comment it out/disable it.
sudo nano /boot/firmware/config.txt
dtparam=i2c_arm=on dtparam=i2c_arm_baudrate=400000 dtoverlay=gpio-shutdown dtoverlay=gpio_pin=4 dtoverlay=active_low=1 dtoverlay=gpio_pull=up
Control O to save, Enter to commit the changes, Control X to exit
Install the following python packages sudo apt install -y python3-pip python3-dev python3-pil python3-setuptools python3-rpi.gpio i2c-tools
Add your user to the i2c group - Be sure to change (username) with your user ID sudo usermod -aG i2c username
Clone the RM0004 repository git clone https://github.com/UCTRONICS/SKU_RM0004.git
Running the "./deployment_service.sh" file in the SKU_RM0004 directory:
Be sure to edit the "deployment_service.sh" file - you will want to update the /boot/config.txt information to reflect /boot/firmware/config.txt, and save it.
**Change the deployment_service.sh file cd SKU_RM0004 sudo nano deployment_service.sh
After you've saved it, you should be able to successfully run it.
Compile cd SKU_RM0004 make
Run the display ./display
you should see the IP of your host, CPU, Memory, Ram, and Temp
Control C to exit the display
Now add the automatic start script - change (username) to the userID
sudo nano /etc/rc.local
!/bin/sh -e
cd /home/username/SKU_RM0004 make clean make ./display& exit 0
Control O to save, Enter to commit the changes, Control X to exit
Change rc.local from read only to executable sudo chmod -v +x /etc/rc.local
Enable rc.local sudo systemctl enable rc-local.service
Start rc.local sudo systemctl start rc-local.service
Validate rc.local service is active sudo systemctl status rc-local.service
Reboot sudo reboot
Your OLED should magically work now without manually running the ./display file.
There are a few folks here that contributed to the overall solutions and want to Thank - WhirlyHat for finding the correct path to the boot file, and bigbrovar for the i2c info and python packages. The Automatic start up script, I had to google and got the answer.
