Other Parts Discussed in Thread: ADS131M08EVM,
Hello E2E Experts,
We are attempting to build a Proof-of-Concept Prototype, based on the TIDA_010243 reference design, using the LP-MSPM0G3507 and ADS131M08EVM. The concept is to use the LP-MSPM0G3507 to capture data, via the SPI port, from eight (8) Wheatstone Bridges connected to the ADS131M08EVM: the connections made between boards are illustrated below.

To view data using the existing "Energy-Metrology-GUI" [GUI] executable, extracted from ADCEnergyMetrologyLibrarySW_1.03:
- Left the TIDA_010243 reference design code running on the LP-MSPM0G3507.
- Exited Code Composer Studio [CCS].
- Cycled power OFF then ON to both boards, to establish a clean, standalone startup and synchronization between boards.
- Modified the .xml file, associated with the GUI executable file, to use one of the available COM ports (COM4, COM5, COM7, etc.).
- Launched the GUI.
However, communication could not be established between the development PC and the LP-MSPM0G3507. Each of the three COM port numbers listed in "4." were used in the .xml file and attempted independently: each attempt failed.
Are there any adjustments (e.g.: code, .xml, hardware, etc.) that can be made to take advantage of the TIDA_010243 working design? If not, is there an alternate GUI I can use to view the data captured by the LP-MSPM0G3507? Please advise.
