Using Matrix Creator HAT - and WiringPi


#1

I just received the Matrix Creator HAT. If you haven’t heard of it, check out their website https://www.matrix.one

I think it’s the ultimate HAT at this point, it has almost everything you could play with, microphone array, Z-Wave, Zigbee, NFC, temperature sensor, humidity sensor, magnetometer, accelerometer, gyroscope, UV sensor, you name it.

The question is how hard it is to make it work on Rock Pi 4.

I’m trying on Debian ARM64, even though the sound is still not working. The first bummer, the starter packages won’t install, including wiringPi (of course) and Matrix’s own init.

I can pull the source code and make it for the latter, however
WiringPi is something I can’t get around. I’m going to port it over, at least Nano Pi has it done already (they borrowed source code from Banana Pro?), hope that will help me get started.

Besides the HyperPixel there is, I believe, no further HAT that uses more GPIO wires of the Raspberry than the Matrix Creator HAT that is going to become extreme. I once glued the GPIO assignments of RockPi and Matrix Creator HAT together.
