| void adc_calibration | ( | void | ) |
ADC Calibration mode.
This function enable/disable the ADC calibration based on the user input from serial console.
For offset calibration user has to connect GND(0V) on ADC input.
For Gain Calibration user has to connect 1.55V on ADC input.
Serial console prints the ADC input voltage after calibration done.

| void adc_differential | ( | void | ) |
ADC Differential mode.
This function configures the ADC as differential mode and converts the differential voltage applied on positive input and negative input. Prints the differential voltage on serial console and disable the ADC.

| void adc_hardware_averaging | ( | void | ) |
ADC Hardware Averaging mode.
This function configures the ADC as hardware averaging mode and converts the ADC input applied on positive input then prints the ADC input voltage on serial console after hardware averaging done and disable the ADC

| void adc_oversampling | ( | void | ) |
ADC Oversampling mode.
This function configures the ADC with normal mode and oversampling feature and converts the ADC input applied on positive input. Prints the ADC input voltage for both mode on serial console to recognize the improvement.

ADC START and Read Result.
This function starts the ADC and wait for the ADC conversation to be complete and read the ADC result register and return the same to calling function.

| void adc_temp_sensor | ( | void | ) |
ADC internal TemperatureSensor mode.
This function enables the internal temperature sensor for ADC input and displays the current room temperature in serial console after the calculation done using ADC result.

| void adc_window_monitor | ( | void | ) |
ADC Window Monitor mode.
This function configures the ADC as window monitor mode and predefine the voltage level for monitoring. If the ADC input exceeds the voltage level the LED0 will be in ON state in SAMD21 Xplained Pro.
