Configure P0.14 and P0.15 as SCL and SDA

[Laurent Bourassa]

Hello,

I have a project where I'm using I2C. I want to configure P0.14 and P0.15 as my I2C pins as I already made a board thinking those would be available, however I get nothing on one pin and some sort of slow clock on the other (Every other pins I have tried for testing purposes have worked fine).

I have read here that pins 14 and 15 for the nRF52832 are GPIOs but also Tracedata pins (which I'm not sure what it is). Could it be what's preventing me from using these pins as I2C pins, and if so how could I reconfigure them for my needs?

Thank you in advance.

Laurent

Hi Laurent

Due to the Easter holiday you will have to expect a delay in replies, sorry for the inconvenience!

Normal mode can always be resumed by performing a "hard-reset" through the SWD interface:

1. Enable reset through the RESET register in the POWER peripheral.
2. Hold the SWDCLK and SWDIO/nRESET line low for a minimum of 100 μs.

Best regards,

Simon
