52833 gpiote gpio 1.x question

[jowei]

Hi Nordic

I want to integrate a push button with 52833 p1.8, base on mesh-sdk light-switch example, (i.e., I may need to modify simple_hal.c)

But after my hours implementation, I still can't  make it.

I don't find where can set p1.x for GPIOTE, the CONFIG register only has 31 bits which seems only can set p0.0~p0.31, 

Can you hint me any example or code to setup gpio interruption on port1.x?

Regards,

Joseph

Hello Joseph,

Please check nRF52833 product specification v1.3, page 151 ~ 152. Table "6.9.4.8 CONFIG[n] (n=0..7) "

There's a data column PORT for us to choose which port to select for current GPIOTE setting.
For P1.8, please set PORT to 1, and PSEL to 18 : )

Best regards,

Rick
