How to use:

Connect RED pin directly to adc.

Connect NOX pin through a resistive divider made with equal value resistors.

-The voltage at the adc should be half the sensor voltage (recommended value: 100kΩ).

Set pin for preheating and the handlers for the NOX and RED adcs:

/* mics4514.h */
#define MICS_PRE_Pin 		GPIO_PIN_7
#define MICS_PRE_GPIO_Port	GPIOB

#define MICS4514_NOX_ADC_HANDLER	hadc1
#define MICS4514_RED_ADC_HANDLER	hadc2

Call the mics4514_init() function on startup

/* main.c */
int main(void)
{
  /* ... */
  
  mics4514_init();
  
  /* ... */
}
