r_adc Module Guide Resources

Last Updated:03/09/2018


Where can I find the references to module guide resources for the ADC HAL module on r_adc?


Information on the module guide itself and the associated resources and known issues are available here.


The ADC HAL module is an API for analog-to-digital conversions and is implemented on r_adc. It supports both the ADC12 and ADC14 peripherals available on Synergy microcontroller hardware. A user-defined callback can be created to process the data each time a new sample is complete.

The ADC HAL module supports the following features:

  • 14-Bit A/D Converter (S3A7, S124) or 12-Bit A/D Converter (S7G2)
  • Multiple Operation Modes
  • Single Scan
  • Group Scan
  • Continuous Scan
  • Multiple Channels
    • 13 channels (unit 0) or 12 channels (unit 1) for S7G2
    • 18 channels for S124
    • 28 channels for S3A7

Module Guide

The ADC HAL module guide is targeted for SSP 1.2.0 and above and the SK-S7G2 Kit.

The most recent versions of the ADC HAL module guide application note, application project and import guide are available here.
