maximum number of high accuracy gpiote in event

[Yadhu KP]

HI,

I'm using nrf52832 with skd 17, i would like to know what is the maximum number of high accuracy gpiote in events that can be used simultaneously?

 You have in total 8 GPIOTE channels available, as per the datasheet:

https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/gpiote.html?cp=4_2_0_20_2#concept_mbf_yyw_lr

 

As long as these remain unused in other modules of your firmware, you shall be able to use all of them.

Note: if you plan to use the GPIOTE PORT event (ie: non-high-accuracy), you need to adjust the sdk_config.h::GPIOTE_CONFIG_NUM_OF_LOW_POWER_EVENTS to match your wanted number of GPIOs.

 

Kind regards,

Håkon
