Tool/software: TI C/C++ Compiler

Hi,

i added come C++ class into the simple_central project and i want to use the class object in c file.

I compile it fine but once i include the c++ header to the project i get a lot of errors.

I did wraped the class with:

#ifdef __cplusplus

#endif

And include the class header with no error but i cannot instanciate an object.

How can i use an object in the c files?

So i think i resolve my issue.
In my c header i just declare a function as "extern" and i implement it on .cpp file
This function i can call from in .c files and in .cpp this function can have c++ objects.

Hello Michael,

you can also have a main() within cpp file and call external regular c functions.
Check the bigtime example available on MSP430FR5994, MSP430FR6989 family or MSP432P401R.

Long time ago I tried, with no luck, to help you with PWM burst.
I have found that:
It is possible to use a timer to trigger DMA (ref data sheet (SLAS704F) Table 6-12) to write a predetermined value into e.g. TA0CTL. This is a cute trick, but not particularly versatile (no decisions).
You can also check TEC:
There is a range of TI products containing Timer Event Control (TEC) like MSP430x5xx and MSP430x6xx Family.
