C-JESTER01

That is the program I found however, when I put it into the arduino IDE, it fails to compile. Any tips? On Sat, Jan 22, 2022 at 15:50 tebl ***@***.***>...

Yes it was missing MCP23S17.h, even though it was included. I changed the path in the program and then it said it was unable to be compiled for that board....

Give me a half hour to pull the error for you On Sat, Jan 22, 2022 at 17:12 Hunter McGuire ***@***.***> wrote: > Yes it was missing MCP23S17.h, even though...
