Detailed Description

Purpose

Interface for configuration the Analog-to-Digital Converter (ADC) peripheral.

Usage

1. Configurate the pins for ADC.
2. Initialize the ADC with ADC_Initialize().
3. Set ADC clock and timing with ADC_SetClock() and ADC_SetTiming().
4. Select the active channel using ADC_EnableChannel().
5. Start the conversion with ADC_StartConversion().
6. Wait the end of the conversion by polling status with ADC_GetStatus().
7. Finally, get the converted data using ADC_GetConvertedData() or ADC_GetLastConvertedData().
