Dear Roberthh The PINs given by Pin(xx) are GPIO numbers, not board PINs. : SDA - GPIO12 and SCL - GPIO13 Is Ground Connected: Yes are Pull-up resistors in place: Yes what is the result of i2c.scan() after instantiating i2c: d58 or 0x38 Still, I'm getting the same error. Traceback (most recent call ...

Dear Roberthh

Thanks for the prompt reply.

I just want to know, do we have to provide external pull-up resistors with Pico?

Thanks
