Hello I have a Raspberry Pi 4 8GB w/ a Pironman Mini PC and the OLED just displays Power Off. I think there is a coding issue. What do you need from me to help solve this?
Before you use Pironman, modify the /boot/config.txt configuration file.
Follow the tutorial link to do so: 5. Set up the Pironman — SunFounder Pironman documentation
Yup, I had followed the tutorial and nothing. Still displaying “Poweroff” on the OLED. Attached picture of the config.txt file. Do you have any other suggestions?
1、First of all, please confirm what system you are using.
2、Is the jumper cap of IO16 connected properly?
If you unplug this jumper cap, the power button will not work. In addition, the power button is also used to wake up the OLED screen in sleep mode.
3、Is the Pironman software service installed correctly according to the tutorial? Is there any error reported during installation?
4、Run sudo Pironman stop && sudo python3 /opt/pironman/main.py to see if there is any error message reported, please provide the log to us.
- Here is what my system is.

2.Affirmative. I’ve verified that IO16 is connected.

I followed the tutorial and had no problems during install.

You update the pironman code version to 1.3.0 to see.
cd ~/pironman
git pull
sudo python3 setup.py install -
If you still have the same problem, please provide the print log to us: sudo
sudo Pironman stop && sudo python3 /opt/pironman/main.py -
Please provide us with a video of the working state of the OLED screen.
I am on 1.4.0. See snipit.
As far as the video. I uploaded it to youtube.
Thank you for your time and attention on this matter.
First, you will IO26 short piece to GND, and then another short piece to the switch button JP2. (as shown in the figure)
Then connect the external power supply power supply to the expansion board, after connecting the power to the main board indicator lights up, and the switch button JP2 short tab is unplugged. (Please check the video)
See if the motherboard indicator light is always on.
Please also provide us with the video after confirmation.
Ok. I apologize in advance but I think I may have found the problem. I was supplying power to the Raspberry Pi 4 and not the pironman PCB. Once I did that the OLED started displaying the “stats”. But now I see another problem. After the initial boot and the OLED displays the stats after the 30 seconds, it doesn’t display anything anymore unless i run “pironman -al on” command, which that command forces the display to be on all the time.
1, our OLED will turn off after 60 seconds by default, a short press on the power button will light up.
If you want the OLED screen to turn off earlier or later, you can execute pironman -s 60 (set the duration in seconds, you can modify the time)
2. If you want the OLED screen to be always on, execute pironman -al on to set it to always on mode.
