Part Number: MSP430F67791
Other Parts Discussed in Thread: MSP-FET
Good afternoon,
I’m working with the EVM430-F6779 evaluation board, which uses the MSP430F67791 microcontroller. According to the Energy Measurement Design Center (EMDC) User’s Guide, the example code EVM430-F6779_CT_3V_3C_60Hz.txt is programmed into the EVM using the MSP-FET. After that, the board communicates with the PC through the HID bridge and the measurements are displayed in the EMDC GUI.
What I would like to do instead is receive the raw samples from the EVM in a different way (for example over UART/RS-232), without relying on the EMDC GUI. The guide mentions that an embedded system can be used for this communication by implementing the EMDC protocol on that processor.
I would like to use a Raspberry Pi 3 for this purpose, but I’m not sure how to proceed:
-
Is there any existing implementation or library of the EMDC communicaction protocol (C, Python, etc.) that I can use on a Raspberry Pi / Linux host?
-
Or is the expectation that I must implement the EMDC protocol from scratch based only on the documentation? If so, is there any more detailed protocol specification, application note, or example code available?
-
Alternatively, is there a recommended way to access the raw ADC samples or computed metrology results directly from the MSP430F67791 (e.g., via UART) without going through the full EMDC protocol?
Any guidance, examples, or references would be greatly appreciated.
Thank you!
