Hello,

I have LED&KEY module (see attached) which works very well on Arduino UNO board; however the same module and sketch does not work on IOT2040. Other Arduino Sketch like the Blink works on the IOT2040 board. Please let me know how can I make LED&KEY module work on the IOT2040.

Thanks & regards.

Hi,

No I'm not using any special library with this sketch except the string.h;

but I'm using the shiftIn and shiftOut functions to read and write on the LED&KEY module.

Regards 

Shall I understand that LED&KEY module cannot work on IOT2040; or is there any solution.

Regards,

no compiler error;

hi,

I have send the code; any help. need to know urgently.
