How to select ADC input on a pin multiplexed with ADC and other functions on TMS320F28069 Piccolo ?

Other Parts Discussed in Thread: TMS320F28069, CONTROLSUITE

How do I select the ADC (analog-to-digital converter) function on pins of TMS320F28069 Piccolo that are multiplexed with other functions; specifically, how would I select the ADCINB6 function on pin 34 of the TMS320F28069PZ, since it is multiplexed with COMP3B and AIO14?

I know how to do this with the GPIO pins -- just use the GPAMUX1, GPAMUX2, GPBMUX1, GPBMUX2, but how do I do this for pins for ADCINB6 (pin34), ADCINB4 (pin 32), ADCINB2 (pin 30),  ADCINA2 (pin 21), ADCINA4 (pin 19), and ADCINA6 (pin 17).

  • Hi,

    You don't have to do anything for ADC functionality. As simple as this example:
    C:\ti\controlSUITE\device_support\f2806x\v151\F2806x_examples_ccsv5\adc_soc

    Do check the ADC peripheral header file.

    Regards,
