| * \section Purpose | |
| * | |
| * Interface for configuration the Analog-to-Digital Converter (ADC) peripheral. | |
| * | |
| * \section Usage | |
| * | |
| * -# Configurate the pins for ADC. | |
| * -# Initialize the ADC with ADC_Initialize(). | |
| * -# Set ADC clock and timing with ADC_SetClock() and ADC_SetTiming(). | |
| * -# Select the active channel using ADC_EnableChannel(). | |
| * -# Start the conversion with ADC_StartConversion(). | |
| * -# Wait the end of the conversion by polling status with ADC_GetStatus(). | |
| * -# Finally, get the converted data using ADC_GetConvertedData() or | |
| * ADC_GetLastConvertedData(). | |
