CCS/LAUNCHXL-F28069M: Voltage Measurement using ADC in LAUNCHXL-F28069M in CCSv8

Part Number: LAUNCHXL-F28069M
Other Parts Discussed in Thread: CONTROLSUITE, C2000WARE

Tool/software: Code Composer Studio

How to configure the ADC for measuring the voltage of an external source connected to the LAUNCHXL-F28069M and displaying it? What is the step by step procedure for using ADC to measure the voltage in Code Composer Studio 8.3.0? In the example program given in CONTROLSUITE ePWM is used. How to trigger the ADC using GPIO pins?

    You can monitor the array of buffered results using an Expressions Window or graph in CCS.  These archived F2806x workshop materials might help with ramping up on the architecture and development environment.  It includes graph examples.

    The controlSUITE and C2000Ware examples are what we typically use to convey how the ADC (and other modules) operate from a CCS environment. The TRM includes all technical information about the features and register definitions.

    ePWM is commonly used as the synchronous ADC trigger for cases where the C2000 device is responsible for both sensing and actuation in a control loop.
