In the case of Adafruit's chips, the HT16K33 is the driver chip that controls the matrix. According to their manual at https://www.alcom.no/wp-content/uploads/2020/01/RB-JoyPi-Manual.pdf, it appears the Joy-Pi uses a MAX7219 chip instead, so this library will not work for you.
For a school project, I am required to access a Joy-Pi's 8x8 matrix. I am trying to do this using
adafruit_ht16k33.matrix.Matrix8x8
:I have tried all addresses from
0x71
to0x77
(I did not try0x70
because that already belongs to the DHT). On all of these, it reports that the device does not exist. All other shown devices do work.Is this something I am able to fix by myself? Should I contact Joy-IT instead? Am I just blatantly doing something wrong?
