Part Number: AWR1843

Here Board_ADCCHANNEL_A1 these macros i was not able to find in "ADCBuf.h", should I have to define those? how do I map the adcChannel to pin. We have 6 ADC channels by giving 1,2,3,4,5 will it take care of the pins and what is the first argument of ADCBuf_open()

    Hi,

    I think there is a confusion

    The adcbuf driver "C:\ti\mmwave_sdk_03_05_00_04\packages\ti\drivers\adcbuf" is related to the ADC Buffer described in Chapter 13 of the TRM (SWRU520)

    Here is a short description from TRM:

    "The ADC buffer is on-chip memory arranged as a ping-pong buffer, with ECC support for each ping and
    pong memory. The raw ADC output data from RADAR-SS is stored on this memory, to be consumed by
    the DSP with the 16xx/18xx, or by the hardware FFT accelerator with the 14xx/18xx for the post
    processing."

    This is not related to the general purpose ADC channels.

    The use of GP ADC channels is not supported with a driver by the SDK.

    There are examples on this forum on how to use the GPADC channels.

    Please use google site search to find out more information:

    Thank you

    Hi,

    Can you please provide example code that show how use GP ADCs and which header file to be included in order to use APIs regarding GP ADCs
