how to program A7 pin in development kit and which pin useful for  3.3 v in development kit

[Simon]

Check out the NCS tutorial and section 3.2 Set it up --> 3.5 Add the ADC peripheral, which will show you how to use AIN0. Just swap out NRF_SAADC_INPUT_AIN0 with NRF_SAADC_INPUT_AIN7.

Best regards,

Check out the sample zephyr/samples/drivers/adc/src/main.c, it demonstrates how to go about this.
