I have just recently started to use PlatformIO and am really liking it, i have converted an Arduino Due sketch and it worked flawlessly.
I also have an Energia sketch that I would like to convert and continue developing in PlatformIO.
But I ran into some build errors at once, mostly concerning the SPI library.
It seems that PlatformIO uses an older version of the framework. Is there a plan to update it?
I tried using a newer version of the framework from github with the correct version of the SPI library but ran into other build errors.
I used this to get the newer version of the framework:
Well if it’s not found the include paths are not ok. The lilbrary does not adhere to the library structure , so utility/inc is not added by default to the include search path.
However the normal include path should be through just #include <driverlib.h>. This includes pmm.h which includes hw_memmap.h which includes msp430f5xx_6xxgeneric.h. So you shuold just #include <driverlib.h> and have your needed header file. Or do it the lengthy way and #include <utility/inc/msp430f5xx_6xxgeneric.h>.
The reason I said the include paths seem ok is that if I build with the normal timsp430 framework then it finds the file even though it is in the same path and the include arguments to gcc are identical. But I guess the file and include structures are more different than I first thought which would also explain why it only finds 22 libraries with the git repo I was hoping would work. It finds 31 with the regular timsp430.
So I guess a way forward is to either fork the repo and make it compatible with PlatformIO or to change the way I use the SPI library, alternatively see if I can add the changes to the SPI library that I need and use my own version of it.
The problem was that I was getting build errors like this:
error: no matching function for call to 'SPIClass::transfer(byte , int)
So I compared the SPI library in the energiamsp430 framework with the one in the latest version of Energia and saw that they differed quite a bit. This was when I tried to update it to the latest version I could find of the msp430 library.
