Programming counters using PropGCC

GuruSantiago

I am woking on some C code to use the propeller counters, but I am having problems accessing CTRA register.

Is there sample code available?

I am trying to rewrite the Counter Modules and Circuit application lab code in C.

Hi there.

The propeller.h and cog.h headers provide access to CTRA and other special purpose registers.

PropellerGCC docmentation is on www.parallax.com/propellergcc and www.propgcc.googlecode.com

Register are accessed like variables. The names are declared as volatile so they will not be optimized away.

// snippet
  CTRA = 0;
  DIRA |= 1;
  OUTA ^=1;
