static void init_adc ( void  )

static

Initialize ADC driver to read the board temperature sensor.

Initializes the board's ADC driver module and configures the ADC channel connected to the onboard NTC temperature sensor ready for conversions.

static void init_pwm ( void  )

static

Initializes the PWM subsystem ready to generate the RGB LED PWM waves.

Initializes the on-chip PWM module and configures the RGB LED PWM outputs so the the brightness of the three individual channels can be adjusted.
