Hi Felix,
Sorry for the delay... my STAMP_PICO project was momentarily shelved but I just resurrected it and found your response.
I will definitely try your suggestion since I would like to keep the native port to flash but I need another UART.
Thank you!

Hello @davidgs

Hmm, I can scan the I2C bus just fine using port A (GPIO0 and GPIO1):

Wire.begin(GPIO_NUM_1, GPIO_NUM_0);

I2C requires pull-up resistors on both lines. GPIO8 already has a 10k pull-up resistor. Did you add a pull-up resistor to GPIO7 as well? Some I2C slave devices might already have pull-up resistors in place tough.

Edit: I've just tried with GPIO7 and GPIO8. The I2C scan works with those two GPIOs for me as well.

Thanks
Felix
