Detailed Description
Purpose
Interface for configuration the Analog-to-Digital Converter (ACC) peripheral.
Usage
- Configurate the pins for ACC
- Initialize the ACC with ACC_Initialize().
- Select the active channel using ACC_EnableChannel()
- Start the conversion with ACC_StartConversion()
- Wait the end of the conversion by polling status with ACC_GetStatus()
- Finally, get the converted data using ACC_GetConvertedData()
