ADS1261EVM: Mutlichannel sampling using ADS1261EVM

Part Number: ADS1261EVM
Other Parts Discussed in Thread: ADS124S08

I don't believe I am able to take continuous multi-channel sampling using the development board with the standard firmware in place. 

If I'm missing something, potentially a script that can achieve this or even for/while loops within them, I'd really appreciate the insight. 

Otherwise, a copy of the source for the firmware so I can modify it for this purpose would be fantastic and I'm sure greatly benefit many people using your development kits. 

Kind Regards

  • Hi Matthew,

    You are correct...the EVM currently doesn't allow for continuous multi-channel sampling. This limitation is mostly an issue with the GUI.

    Since this is a popularly requested feature, we will try to provide this in a future UI implementation, but I don't have a planned date for when that might become available.

    Regarding the firmware
    We can't provide the full EVM firmware source code, but there is subset of the firmware for the ADS1261EVM found here: http://www.ti.com/lit/zip/sbac199. Unfortunately, this code doesn't show how to initialize the Tiva MCU or provide any PC interface; however, I might also recommend looking at the ADS124S08 example code (http://www.ti.com/lit/zip/sbac159) which does show additional configuration examples.

    Best regards,
    Chris
