Gpio logic high all the time

[Pepam]

Hi,

I my design I want to use load switch from TI TPS22946 which have enable pin sensing logic low/high. I would like to be able to enable load switch with nrf52's gpio, but don't know how to do this. The pin have to be high all the time for the load switch to be in ON state even with softdevice enabled. Please any suggestion how to achieve this?

Thanks,

Pepam

Hi,

First you have to enable the pin as an output:

nrf_gpio_cfg_output(pin);

Next;

If you want to set the pin high:

nrf_gpio_pin_set(pin);

Or;

If you want to set the pin low:

nrf_gpio_pin_clear(pin);

best regards
