I have a question: Can the value of RA in the RA compare match of the Arduino DUE microcontroller Atmel SAM3X8E be a variable value like a sine function instead of a fixed value?
No, RA stands for Register A. All it does is hold a 32-bit integer value. To update the value of RA every compare match with RA, then you need to enable interrupts for the time channel and create a handler function. This handler function would then call your sine function and store the returned value in RA every time a compare match with RA event. NOTE: If your code takes longer (clock cycles) to update the value of RA than the period of the timer channel, then you'll end up with undefined behavior.
