nRF52840 SDK 15.2
I want to control the power of sensor, so I configurate the pin like this:
nrf_gpio_cfg(AFE4403_PIN_PWR_EN,
NRF_GPIO_PIN_DIR_OUTPUT,
NRF_GPIO_PIN_INPUT_DISCONNECT,
NRF_GPIO_PIN_NOPULL,
NRF_GPIO_PIN_S0D1,
NRF_GPIO_PIN_NOSENSE);
When I intended to power off the senser, code as below:
nrf_gpio_pin_set(AFE4403_PIN_PWR_EN); // Power off senser
But I can't close the CMOS, means that measure the D pin of CMOS and voltage is not zero, equal VBat.
Measure the G pin of CMOS, the voltage equal 3.4V.
I don't understand where is my mistake about the code of configuration, could you help me?
