GPIOTE interrupt not trigered

I found the error I made. I was using nrf_gpio_cfg_sense_input on an other IN pin. It was blocking Interrupt on other nrf_drv_gpiote_in_init IN pins...

For information, it is not a problem of speed, the signal is changed only on action of nRF, and more overs, interrupt is not triggered ones

OK so SPI and other peripheral do not use LP event. I am already debugging, and no error ... step by step init seems OK... with also RTT ... There is just no Interrupt when with "fasle", and there is when "true". So PIN assignment are also OK.

All modules using a GPIOTE EVENTS_PORT is a LP event. If you are e.g. using the app_button library, a button press is a LP event.

What pins are you using in your project? Make sure that you don't use any of the pins used by the SPI or any other module.

If you are still having this issue, you should debug to see if you are running into the error-handler. See this post about debugging.

And do work with "true"

Hi,

Thanks, it works for the SDK example ! But still do not in my project ... I already had 4, but even trying with GPIOTE_CONFIG_NUM_OF_LOW_POWER_EVENTS = 8

What does count as LP event ? I have SPI initialised, and some other input pins with no interrupt ...

Hi,

When you are using the GPIOTE module in low accuracy/low-power mode by calling the GPIOTE_CONFIG_IN_SENSE_TOGGLE() function with the .hi_accuracy flag set to false, you need to make sure that you have configured the GPIOTE module for enough low-power input pins. I.e. make sure that GPIOTE_CONFIG_NUM_OF_LOW_POWER_EVENTS in sdk_config.h corresponds to the number of low-power events you using.

I use nRF52832's nRF52DK and SDK12.3 and SDK14.0 I use 2 button on the nRF52Dk and It works.

As you said it works for you, I tried whit SDK 12. It seems to do different, but does not work neither ... What version of SDK do you use ?

In my code 2 input work fine GPIOTE_CONFIG_IN_SENSE_XXX(false) --> works GPIOTE_CONFIG_IN_SENSE_XXX(true) --> works
