TMS320F28P550SJ: Confusion related to ADC trigger sources

MUKUL CHOUDHURY

Part Number: TMS320F28P550SJ
Other Parts Discussed in Thread: C2000WARE

Tool/software:

Hi,

There is a discrepancy between the ADC trigger sources mentioned in F28p55x TRM ans the ones availble in the header file in driverlib.

file: C:\ti\c2000\C2000Ware_5_02_00_00\driverlib\f28p55x\driverlib\adc.h

TRM:

Please let me know is eCAP available as ADC trigger sources?

Thanks,

Mukul

    Mukul,

    I'm looking into this, I believe that ECAP triggers are there, but in slots 29/30 vs what is shown in the TRM.  The TRM contents are incorrect, and with the exception of ECAP should match the driverLIB.

    I should have an answer on the ECAP triggers by tomorrow worst case.

    Best,

    Matthew

    Mukul,

    After looking into this, the Driver LIB implementation is correct.  There is no eCAP SOC triggers on this device; this is a new feature from Type 3 eCAP(not related to the ADC Type) that is only available on F28P65x device currently.  F28P55x has Type 2 eCAP, which did not have this support.

    Best,

    Matthew
