CCS/TMS570LS0714: ADC module

Part Number: TMS570LS0714

Tool/software: Code Composer Studio

Dear E2E:

   Recently,we found that the result value in ADC1 is a little bigger than in ADC2 when we read voltage from AD module.So I have some problems as following:

(1)There are two ADC module in TMS570LS0714(ADC1 and ADC2).What's the differece between them?

(2)There are two ways to read the result from ADC module.(FIFO and RAM).Under the same conditions, Which way can get the result much faster?

(3)What should we notice, when we use ADC module?

Thanks and Regards, 

Yu Chen

    Hello,
    You can try to increase sampling time.
    Different packages has different count of ADC cahnnels (PGE got 24 ADC1 channels and 16 ADC2 channels, PZ got 16 and 8 respectively). ADC2 channels are all shared.
    When reading directly from RAM, you can read selectively conversion results. When reading from FIFO you should read out conversion results sequentially.

    Best regards,
