GPIOTE input pins dont work

[LeonardPak]

Hello,

I use NRF52810 with SDK 14.2.0 and softdevice 112. I need to use 7 input pins,  but if I config more than 3 pins, all signals disappear.

GPIOTE_CONFIG_NUM_OF_LOW_POWER_EVENTS is setted to 7.
My configuration for each pins is like below:
	/**< INPUT. */
	nrf_drv_gpiote_in_config_t config_pwr = GPIOTE_CONFIG_IN_SENSE_TOGGLE(false);
	// BTN_PWR
	err_code = nrf_drv_gpiote_in_init(BTN_PWR, &config_pwr, PIN_EVT_Handler);
	APP_ERROR_CHECK(err_code);
	nrf_drv_gpiote_in_event_enable(BTN_PWR, true);

Input pin has external pullup, no pullup settings in code. It switche like this ESE22MV21 . And it pulls down.

What is your GPIOTE_CONFIG_NUM_OF_LOW_POWER_EVENTS defined to in sdk_config.h?

And do you have logging enabled? Can you please try to define DEBUG in your preprocessor defines, and monitor the log? Does the log say anything?

BR,

Edvin

What do you mean by logging?

// <o> GPIOTE_CONFIG_NUM_OF_LOW_POWER_EVENTS - Number of lower power input pins 
#ifndef GPIOTE_CONFIG_NUM_OF_LOW_POWER_EVENTS
#define GPIOTE_CONFIG_NUM_OF_LOW_POWER_EVENTS 8
#endif

If you use one of the examples with BLE, then you probably see some calls to NRF_LOG_INFO(); in the project, do you?

What is the following defines set to in your sdk_config.h:

NRF_LOG_ENABLED
NRF_LOG_BACKEND_UART
NRF_LOG_BACKEND_RTT

Yes. I have this function and log_init(), but dont undestand, how it can help me.
