Add All-in-one PCB board without zynthian os on raspberry

Hardware
#1

Hello,

i want to add the all-in-one PCB board without zynthian os on a raspberry pi 4 because i want to
take another software thats run on wine.

The Pcb23017 is wired on i2c!
I’ve allready enabled the i2c.

Now, i want to configure the adresses (0x20). have you a script that i can implement?

Thanks
Marco

Hi, maybe this can help:

It’s already in use in the Zynthian Zyncoder lib

#3

ok thanks, and after the install off the wiringpi?

with “scratch” assigning the pins?

What do you want to do with the All_In_One module?

The All_In_One module have 2 parts:

  • MCP23017 GPIO expander:
    It’s a raw hardware device specially designed for zynthian. If you want to use it with a different software, you must write some code by yourself. In such a case, you could take the zyncoder library as a base.

  • MIDI interface: The MIDI interface uses the RBPi UART pins. You would need the “ttymidi” driver for using it.

Good luck!!

Thanks, i’ll try it

Hello,

Which pins do I have to control on the all-in-one module and which on the Raspberry (Rx and Tx I think), but which Gpios on the All-in-one Modul (5,5v, ground, leds, Midi in and Midi out)?
I connected everything like the v2 kit (hifiberry dac+, Piscreen3.5, Midi in-out-thru, 4 encoders)

You have the schematic and other design files on the github repo:
