Module sam4l::adc
[−]
[src]
Implementation of the SAM4L ADCIFE.
This is an implementation of the SAM4L analog to digital converter. It is bare-bones because it provides little flexibility on how samples are taken. Currently, all samples:
- are 12 bits
- use the ground pad as the negative reference
- use a VCC/2 positive reference
- are right justified
Samples can either be collected individually or continuously at a specified frequency.
