ADS1x9x evm source code

Other Parts Discussed in Thread: ADS1292R, ADS1292

Hi All,

I am working with ADS1292r. Its kit can be accessed thorough  ADS1x9xECG-FE Evaluation Software. There is a source code in its "Firmware" folder. I uploaded its generated hex file. I disabled the kit until I reset it. 

I am looking for another source code which not to disable the kit!  In another post it is mentioned that another source code existed at least at 2012.

    Hi Mohsen,

    The firmware update for the ADS1292 is noted in section 7 of the ADS1x9x EVM Users Guide.  Have you followed the BSL procedure described there?

    Hi Tom,

    Yes, I did it based on the User Guide. I have a different question. If I want to have a new firmware I should have a source code. There is a source code in the "Firmware" folder in the kit software. I generated the new firmware from that source code, but it disabled the device completely!

    As I searched in the posts, I found that there is another source code available(I put that posts, link in my previous post here).

    Best,
    Mohsen

    Hi Mohsen,

    That post you referred to is over 4 years old at this point. I believe the 'updated firmware' mentioned in that post is the update included with the rest of the ADS1x9xEVM installation package. Just a reminder though, that update was based on our existing GUI - if you modify and re-compile the source, it may not work correctly on your board.

    Tom,

    You are right. Anyway current source code does not generate the proper binary file.

    My exact problem is that I need to disable the electrodes in a way that just one of them will be activated (acquire data) and the remaining electrodes will be disabled. First of all, I am not sure that it is possible to work with one active electrode.

    If the answer to the first question is positive, as I checked it is impossible to disable the Multiplexers from the GUI. So is there anyway to disable them, I can access the ADS1292r through SPI or MSP.
    It seems to me with the its standard kit, it is impossible to access the SPI. For the latter I thought it may possible to access thorough the source code( As I wrote above these things are written with 'yes' reply to the first question).

    Can you let me know about these two questions?

    Thanks a lot for your time,

    Mohsen.

    Hi Mohsen,

    Sorry for the delay in getting back to you on this. From the standpoint of the ADS1292, you can certainly turn off one of the channels and work with a single electrode. Modifying the source code and using the MSP430 on the standard kit might be challenging though. Do you have the means to create your own printed circuit board?

    Hi Tom,

    I tried both electrodes ( RA and LA), while one channel is powered down; they both were working and gave the ECG signal. How can I be sure that just one of them(For example RA) is active and the other like LA and RLD are disabled?

    I put here the Registers map. based on this would you tell me how to set the values that cause just one electrode activation?

    Best,

    Mohsen.

    PS: when I powered down one channel I tried different configuration including  "Input short"
