sudo python3 its-a-plane.py does not show data on matrix

[graememilne]

sudo python3 its-a-plane.py, if i type this, the matrix does not show anything. At the bottom of the command ,to exit ctrl +c shows. Which to me it means no errors and it is running ? ( cd its-a-plane-python then type sudo python3 its-a-plane.py) I have set it up to start at bootup and checked it with no errors showing. The funny thing is, i use the demo command it works and it shows the data of aircraft etc on the matrix . (cd rpi-rgb-led-matrix ,cd examples-api-use then type as below) sudo ./demo -D1 --led-rows=32 --led-cols=64 I wonder if you can give me any hints to why the matrix does not show data using sudo python3 its-a-plane.py plane.log file is empty.

I have set it up in “convenience” setting

I had this exact issue the other day and I debated about whether to post anything, for fear I was being silly and that it was something everyone would know. So I'm glad you've posted this!

For me, the issue related to the hardware that is written in the code. Open the following file:

/display/init.py

Line 52 - options.hardware_mapping = "adafruit-hat-pwm"

You need to change this last part to simply "adafruit-hat"

Save the .py and reboot. This worked for me!

Edit: Should also have taken the opportunity to Colin for sharing this project. I'm happily writing this as I watch all the flights departing Heathrow using the matrix!

I've updated the code and added a config option so you can enable/disable the HAT PWM functionality.

In the config you can say HAT_PWM_ENABLED = True or HAT_PWM_ENABLED = False

The default assumption is you've added the solder bridge.
