Hi !
I'm trying to expand the number of GPIO on my Pico with an mcp23s17 but it doesn't work at all. My code is here :https://gitlab.com/roza-tronic/roza-I/- ... 0V4/main.c
I've made a lot of modification & test but i can't get any signal out of the mcp. But as i've never worked with mcp's i' cant even know if it is a problem of wiring or programming and i'm not far to just give up ( i've passed too much time with absolut no result).
here is my scheme : https://gitlab.com/roza-tronic/roza-I/- ... type=heads
As you can see i didn't plugged the reset pin, is it wrong ?
