I am trying to do the blinky program with c plus plus over the Red suite IDE.
After the C++ wizard i just add (gpio.c(renamed to .cpp), gpio.h) and copy the systick function from the c example. The code compiles with no errors. But after upload to the board , the LED doesn't blink. I am quite a noob at programming, and I really don't understand the core of the languages. If someone can hint me what to do or read how to learn to do cpp programs with the lpc.

Imagine this is a name mangling issue with the systick interrupt handler and you need to add an [FONT=Courier New][SIZE=2]extern "C"[/SIZE][/FONT]...

extern "C"
void SysTick_Handler(void) {
  msTicks++;                        /* increment counter necessary in Delay() */
}

and everything is SUPER now

thanks

Now I need to learn how to figure out when and where to put extern 'C' in my development process
