how to retrieve data from ads1282

Other Parts Discussed in Thread: ADS1282, ADCPRO

I want to take two data from ads1282 with adc pro software. I want  AIN1 and AIN2 data to be separated but when I selected AINP1/ANN1 and AINP2/ANN2, these data were averaged instead. Is adc pro able to get separated data from data input?

Can two mmb0s be used simultaneously in a single computer using adcpro? Is there alternative way rather than using adcpro?

    Hi Insan,

    The "AINP1/ANN1 and AINP2/ANN2" MUX connection corresponds to the "011" MUX register field setting that shorts AINP1 to ANN1 and shorts AINP2 to ANN2. That's why it looks like data is being averaged.

    ADCPro is only programmed to collect data from the ADS1282 1 channel at a time. You can independently collect data from each channel and save the data. Then you could put it excel at look at the data sets together. However, there is no way to collect the data simultaneously.

    No, ADCPro was not programmed with that capability. You would need to use separate PCs.

    The ADS1282 input channels are MUX'ed so you cannot really collect two channels worth of data simultaneously. For true two-channel  simultaneously sampled data you would need to use two synchronized ADS1282s. With a single ADS1282 you can multiplex between channels, but that may not be very practical due to the long FIR filter settling time.
