Can you please give me a solution, how can I control the LED in this example (see the attached picture)? PICO can now see the MCP23S17 (see console.log() on the IDE picture), but I cannot control the LED (on/off) with port.A0.* or other commands - what I'm doing wrong?
The cabel numbers on the picture:
1-white) to PICO B15 (MCP->14)
2-green) to PICO B14 (MCP->13)
3-yellow) to PICO B13 (MCP->12)
4-red) to PICO A8 (MCP->18)
5-black) direct to USB-
6-red) direct to USB+
Many thanks in advance!
