Compiler/ADS1263EVM-PDK: How decided Data Acquired sizes(each ADC1 and ADC2) ?

Part Number: ADS1263EVM-PDK
Other Parts Discussed in Thread: ADCPRO, ADS1263

Tool/software: TI C/C++ Compiler

Hello.

I use sbac160(LabVIEW source code). I know how I can get Data Size of only ADC1 Data.((Decided block size by # of samples) * 128 or 126 byte data per # of Samples)

However, in case of "Capture ADC2 Data?" is ON, I don't know follow of pattern of Data sizes of ADC1 and ADC2.

(e.x. in case of # of samples:100, Capture ADC2 Data?:ON, Register Map:Mode2:20sps, Register Map:AD2CFG:10sps is that ADC1 Data Size is 228, ADC2  Data Size is 113)

Could you tell me in case of "Capture ADC2 Data?" is ON that ADC1 and Adc2 Data Sizes follow of pattern?

  • Hi user6222492,

    The ADS1263 has two different ADCs as you are aware.  They may not run at the same data rate and they do not have the same data length.  In ADCPro (or LabVIEW code) there may be more actual data transmitted than is actually shown due to timing.  As to the number of actual samples transmitted for ADC2, it will depend on the number of samples actually transmitted for ADC1 and the differences in data rate between the 2 ADCs.

    Best regards,
