hello everybody :) I am new user, i hope i am in the good section ! 1st - sorry im french so i use google translate to try to explain my problem .. :) 2nd - ENVIRONMENT /nucleo 32-l432kc /IDE ARDUINO /Wire.h /all Register 0x00 /ADDRS : mcp1 0x20 /ADDRS : mcp2 0x21 /ADDRS : GPOIA 0X12 /ADDRS : GPIOB ...
