I2C bus on the Pi #5

Closed jfr26 closed 2 years ago

jfr26 commented 2 years ago

The I2C bus on the Pi 4 is different from that on the Pi 3. Does this affect the interaction with the DMD board? Following the setup instructions as given on this Github does not work with a Pi 4 at the moment.

I managed to get an image by using

i2cset -y "ffffffff00000002.i2c" 0x1b 0x0b 0x00 0x00 0x00 0x00 i i2cset -y "ffffffff00000002.i2c" 0x1b 0x0c 0x00 0x00 0x00 0x1b i

instead.

Hey @jfr26, I already heard from your problems you were facing from @rwb27. "you see an image" means, it works?! :) Would you mind making a PR to add this to the docu? also if you have any notes, where you got stuck in the documentation, please blame me for improving it! I think it is not fully reviewed so that others can replicate it easily. Thanks! :)
