I want to interface 3 custom made heater boards to nrf5340dk. Where the simple task is to toggle gpio's to Turn ON & OFF the heater board.
Now, we are using P 0.01, 0.02 & 0.03 pins to control the heater board.
But, as I see these pins are mapped to P0.00, 0.01 - XL1 & XL2 and P0.02, 0.03 - NFC1 and NFC2 respectively. May I know how can I configure them to work as simple GPIOS so that I can toggle them.
Went through some of the references and did the below steps but not working.
In prj.conf
CONFIG_GPIO=y
CONFIG_CLOCK_CONTROL=y
CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y
CONFIG_CLOCK_CONTROL_NRF_K32SRC_XTAL=n
CONFIG_SOC_ENABLE_LFXO=n
CONFIG_NFCT_PINS_AS_GPIOS=y
