Software changes necessary to use the ADS1198 ECG-FE board instead of the ADS1298ECG-FE board in the TMS320C5515 DSP (MDK)
I have an ADS1298ECG-FE board that we are using to run the software provided with the ECG Implementation on the TMS320C5515 DSP Medical Development Kit (MDK) with the ADS1298 ECG-FE and everything works fine.
Our target is to use the ADS1198 and ADS1194 (16 bit versions of the ECG FE) instead of the ADS1298 (24 Bits).
Is there any information on which changes in the sofware provided with the TMS320CD5515 DSP MDK are necessary so that we can test these 2 other 16 bitversions of this ECG FE chip?
We already ordered the ADS1198ECG-FE board that came with the ADS1198ECGFE-PDK Front End Performance Demonstration Kit.
I know that I have to change the software to handle 16 bits (ADS1198) instead of 24 bits (ADS1298) but I can't get it to work correclty when I change the FE boards.
I see you posted a similar query on the C5000 forum regarding using the ADS1198 in place of the ADS1298 MDK setup. We'll only be able to provide limited support here, as that software was developed by the C5000 applications team. We'll post the source code we used for the ADS1198 here (under the Design Notes tab - FAQ's about the ADS1x9x) and show you haw we accommodated the 24-bit status word and 16-bit data word transfers on our hardware. You might be able to modify the MDK software from that example, or perhaps get some additional insight from the C5000 applications team on how to proceed from there.
The ADS1198ECG-FE firmware that Tom referred to is now posted at http://e2e.ti.com/support/data_converters/precision_data_converters/w/design_notes/1782.aspx.

Thanks for the information. We just received the link for the MMBO firmware for ADS1198 PDK. We will try to figure out the mods we need to do on the MDK software to accomodate the smaller ADC resolution of the ADS1198. Meanwhile if the C5000 team send any input it will be great.
Thank you Greg.
