Hy,
I had some parts laying around and decided to do something with it: Trying out Zynthian.
I have Raspberry Pi 3B and a 7" Touchscreen (USB and HDMI) already running Zynthian with dummy config.
I Also have a MCP23017, encoders and a Pisound laying around. I read about problems with the pins using a Pisound but also that these Problems are fixed with the new all in one board that is using MCP23017.
What do i have to do to get the Pisound working with the encoders?
EDIT: Just found out, that the pins are configurable in the webconfig tool. Great!!
Thanks! I just had a look at the available Pins when using a Pisound. I have the I2C Pins available on the PiSound Headers (BCM 2 and BCM 3). In the schematic MCP pins 19 and 20 are connected to BCM 26 and BCM 16. These two pins are not available when using the Pisound.
Can i change the mappings in the software so i can use two of the remaining pins? Available on the Pisound header is BCM 2,3,4,5,6,7,14,15,22,23,27.
I wired everything up on a breadboard following the schematics. But it is not working.
I can see, that the MCP23017 is detected, but the encoder Test is not changing.
I did all the encoder testing without it. I have some replacements ordered. Iβm pretty shure the MCP23017 is dead. I noticed that it got pretty hot, maybe there was a short i didnβt notice on the breadboard somewere.
