MSP430I2020: IAR Toolchain and Legacy e-meter Library Build configuration

Hi Chris,

Thanks for posting your question to E2E.

Do we recommend that “emeter-toolkit” should be built as a Library with configurations shown on the screenshot attached?

Yes, that's correct. Both the toolkit and metrology projects should be built as libraries.

Customer will be using MSP-GANG Programmer to program the metering IC (MSP430-2020). Based on the MSP Gang Programmer User’s Guide (https://www.ti.com/lit/ug/slau358q/slau358q.pdf?ts=1610126148828&ref_url=https%253A%252F%252Fwww.google.com%252F) it appears users can select only a single code file (TI.txt) to be programmed (2.1.1). Therefore, I assume that one of the three projects should be executable and two other projects should probably be libraries. Does it make sense? If so, which project should be built as the executable one?

The three projects should be compiled in this order: toolkit > metrology > application. The executable generated by the application project is the one that should be used for programming the device.

Also, when building the “emeter-metrology” project some errors [Pe1696] are generated (see screenshot attached). It seems like the “signal.h” and “inttypes.h” libraries could not be found. Do you know how one can fix this error?

I haven't seen this error before, but I suspect it has to do with the directories not being included for these files. I searched the forum for the compiler errors and found several threads that should help. One recommended going to Project -> Options -> C/C++ compiler -> Preprocessor and add the directories where the files can be found.

• Error[Pe1696]: cannot open source file with IAR
• Please help me with this ====> Fatal Error[Pe1696]: cannot open source file "delay.h"
