CCS/MSP432P401R: Problem with old program

Hello,

Sylvain Dutrieux said:

If I try to flash it now, the compiler doesn't recognize some functions like CSCTL0 = DCORSEL_3; or INT_EUSCIA1 for example.

I assume you are getting build errors when trying to debug the project. Can you provide all the text in the build console? You can copy and paste to a text file and then post the text file to this thread.

Thanks

Hi, thank for your answer ; here are the errors. The code was perfectly working before. I'm currently changing the syntax of the code. Thank you

Where are those identifiers defined? It looks like some header file that defines them is not being included. Did you make a copy of the original project?

Yes, it is the exact copy with all files included... it seems like the functions are not recognized anymore. I had to update all registers and bits (for example INT_EUSCIA1 has become EUSCIA1_IRQn)

An idea why?

Thank you

It is hard to say without having the project locally to examine. I suspect you are relying on MSP device support files and those files have changed when you updated CCS or the SDK version you are using.

I will move this thread to the MSP forum. The experts there can help you further.

Thanks

Hi Sylvain,

When you developed the old code, what was the version of the CCS and MSP driverlib that you were using?

When you are rebuilding now, what is the version of the CCS that you are using?
