CCS/MSP432P401R: MSP432 ADC14

Part Number: MSP432P401R

Tool/software: Code Composer Studio

Do we have any example codes for setting up the ADC14 (in MSP432) to work as "Pulse Sample Mode"? This mode is described in page-667 of SLAU356D (MSP432P4xx Family, Technical Reference Manual).

Thanks!

    It's not clear which source you're looking to use, but the "adc14_single_conversion_repeat_timera_source" 
    example configures the ADC to use TimerA as a trigger, which operates as a pulsed sample.  This code is available 
    from Resource Explorer at dev.ti.com at the following path:

    SimpleLink MSP432 SDK -> Examples -> Development Tools -> MSP-EXP432P401R -> Driverlib 

    A snippet of the code is shown below for reference:

    /*
    * Configuring ADC Memory, repeat-single-channel, A0
    */
    MAP_ADC14_configureSingleSampleMode(ADC_MEM0, true);

    /*
    * Configuring ADC Memory, reference, and single ended conversion
    * A0 goes to mem0, AVcc is the reference, and the conversion is
    * single-ended
    */
    MAP_ADC14_configureConversionMemory(ADC_MEM0, ADC_VREFPOS_AVCC_VREFNEG_VSS,
    ADC_INPUT_A0, false);
    /*
    * Configuring the sample trigger to be sourced from Timer_A0 CCR1 and on the
    * rising edge, default samplemode is extended (SHP=0)
    */
    MAP_ADC14_setSampleHoldTrigger(ADC_TRIGGER_SOURCE1, false);
