ADS1292RECG-FE: Using the eval board with windows 11 pro installation

Hi,

The GUI may not support Windows 11.

Please try

disconnect EVM from computer

and

uninstall completely 

and

without connecting evm to the computer, reinstall the GUI using Administrator mode again.

See if above helps, or try above on a Windows 10 computer.

Thanks

Hi ! I got it to work. I ran the software as admin and it worked. No uninstallation reinstallation needed. The most painful part was getting the right drivers to work though. Thank you so much. I have another question regarding using ADS1292RECG-FE. Can i use this eval board to test a one channel EEG setup ? If i want to just test the board and see if it is working right by inputting a Sine wave of like 20hz and see if I am able to read that back, should I use channel 1 or channel 2 ?

Hi,

Highly appreciate for letting me know. Glad that you got it installed.

Would you mind describing a bit what do you mean by getting the right drivers?

------------------------------------------------------------------------------------------------------------------------------

ADS1292R was mainly designed for ECG application although some people may use it for EEG.

May I ask what equipment or source you plan to use to inject the 20Hz sine wave? and how big of the Vpp?

Please make sure the waveform injected are differential and the differential signal in less then 5 mV range, which is usually challenge unless using an ECG simulator, which we always and highly suggest to start with.

Thanks

As I use windows 11 , to install the ADS driver that came with the software install I had to disable driver security signature first, for which i needed my Bitlocker keys. After that I had to go to the device manage and update the driver manually.

Ahh, I was thinking of using a signal generator to generate a waveform and right now I had upto like 200mV(which now I realize would be too high and not differential). I have a ne-tech EEG simulator which I could use for this otherwise. But I should apply the signal between what pins of the DB9 connector ? and should I be connecting the ground of the simulator to the ground of the EVM ? Do you have any other EEG simulators you would recommend for testing this ? 

Hi,

Regarding to the DB9 pinouts, you will need to follow user guide https://www.ti.com/lit/ug/slau384a/slau384a.pdf?ts=1681479854251&ref_url=https%253A%252F%252Fwww.ti.com%252Ftool%252FADS1292RECG-FE

particular the schematic portion from page 51 to see which INxP and INxN you want to inject differential signals, there are only two channels, so you may try one or both. 

--------------------------------------

Regarding to what signal to inject, official recommendation is always using ECG or EEG simulator and make sure they are differential outputs.

Then, one could starts with low frequency(e.g. 1 Hz) and low amplitude(1 mV) to make some observations and get some understanding and then gradually tune up or down the frequency and/or amplitude step by step and also make observation and understand along the process if one is not yet a biopotential measurement profession or expert.

Thanks
