CC2745P10-Q1: When will support performing conversions on multiple channels simultaneously?

Part Number: CC2745P10-Q1

Tool/software:

Hi Team,

Accroding to the ADC Buffer API doc, I have noticed ADC Buffer Driver doesn't support this now.

SDK: simplelink_lowpower_f3_sdk_8_40_00_61

My customers need this feature. When will support performing conversions on multiple channels simultaneously?

Thanks.

Best Regards.

Connor.

  • Hello Connor, 

    Apologies for the delayed response. 

    I am following up with our ADC team for more information. I will have a response by Wednesday (01/28). 

    Thanks for your patience. 

    Best, 

    Isaac

  • Hello Connor, 

    Are you asking about the post processing of the ADC output data, or the ADC hardware performing multiple conversions at a time? 

    Performing conversions on multiple channels simultaneously will not be supported in future releases. This is a limitation of the ADC hardware on the CC2745R10-Q1 device. 

    Processing the data sequentially can be done by using the ADC_convertChain function. The function optimizes sequential conversions for the digital data from the ADC output. 

    Let me know if you have any other questions. 

    Thanks, 
    Isaac

  • Hi Isaac,

    Thanks for the information. Is there any example on how to use ADC_convertChain?

    BR,

  • Hello Connor, 

    Within the ADC API documentation, there is a snippet of example code for ADC_convertChain. See the Executing Multi-Channel Samples section

    No ADC_convertChain example project is available. Two ADC example projects, adcBufContinuousSampling and adcsinglechannel, which can be leveraged within the SDK. 

    Let me know if you have any more questions!

    Thanks, 
    Isaac
