nRF54L15 DK I2C and SPI Pins

[Theja]

Hi,

I recently started working with the nRF54L15DK and nRF Connect SDK 2.9.1. I'm trying to use I2C21 and SPI00, but I noticed that certain pins on the development kit always result in input and output errors for I2C, and SPI isn't working either. I wanted to know if there are specific pins designated for I2C and SPI, or if any GPIO pins can be used. Please help me resolve this issue.

Regards,
Theja.

Hello,

No, you can't use P2 for TWI/I2C. There was a documentation bug when the nRF54L15 was launced, which caused this confusion. It used to say that you could use dedicated pins on P2 for TWI, but no pins were dedicated/specified. 

This has later been removed from the documentation, as you can't use P2 for TWI/I2C.

Best regards,

Edvin
