can uart enable at p0.9 p0.10 of nrf52832?

[jowei]

Hi nordic

I've try to enable 115200 baud UART on p0.9 and p.10 but I can't make it.

I just saw a thread about 52840 can't use 115200 uart at p0.9, p.10:

https://devzone.nordicsemi.com/f/nordic-q-a/50112/can-nrf52840-p0-09-p0-10-be-used-for-115-kbps-uart-output

So is 52832 has same issue?

Regards,

Joseph

Hi Nordic:

Besides, for PWM, can PWM output at every ports (p0.1~p0.31?)

Thanks

Hi Joseph

Yes, pins P0.09 and P0.10 are NFC pins by default on the nRF52832 and the same restrictions are valid for it as well.

The PWM can be assigned to any GPIOs, just keep in mind that pins P0.22-P0.31 are also recommended to use at Low Drive, Low frequency as these are located near the radio and might cause interference if used at high frequencies while the radio is running.

Best regards,

Hi Joseph

I would like to use P0.9 & P0.10 as GPIO/ UART too. Would you share your solution with me?

DK default has NFC function. Is it necessary to create new board to instead of DK?

Wish to hear your message soon.
