MSP430I2040: Is it Possible to integrate MSP430i2040 with TMDXEVM3358?

Part Number: MSP430I2040
Other Parts Discussed in Thread: TMDXEVM3358

I am planning to develop a modular project for single phase energy metering using MSP430i2040. Is it possible to integrate the energy metering code into the TMDXEVM3358: AM335x Evaluation Module. If this possible later I can use the AM335x Evaluation module as my development kit for further enhancement and development.

Please share your thoughts and experience.

    Pandithan,

    Some of the devices in the MSP family are specifically designed for energy metering. The i2040 is one of these devices. It has superior analog and the right peripherals to successfully develop an accurate energy meter. If i understand you correctly, you want to know if the code on the i2040 can be moved into the AM335x EVM. While, this is definitely possible, i list the following limitations of this approach

    1. Not too sure if the AM335x EVM has the right analog to interface to the AC voltage and current signal.This means you cannot feed High voltage and High current AC signals directly to the EVM. 
    2. The AM335x doesnt have the right Analog compared to the i2040, which has simultaneous converting 240bit sigma-delta converters. 12-bit SAR will not give you the best results and you will have to include code to account for conversion delays between voltage and current samples. 
    3. Not all the SW is in C, some of the SW functions are in assembly, which will not directly port over from MSP430 to AM335x
    4. There is a significant amount of work to do the porting of the overall SW to the AM335x, that needs to be tested and proved to working as expected. This will not get any support from TI

    Is there a specific reason you want to do this? To me, it is not the best use of your time to do the porting from MSP platform to AM335x, unless there is a strong reason. 

    Thanks
