Compile error for GrblHAL SAM3X38E on Arduino DUE about sam3x8e HOT 3 CLOSED

OK, I have surprised myself, and located the problem. Index variable i does not get declared in the driver_init function if the MPG mode pin is not defined.

By changing:

#ifdef MPG_MODE_PIN
// Pull down MPG mode pin until startup is completed.
uint32_t i = 0;
while(mpg_pin == NULL) {
if(inputpin[i].id == Input_ModeSelect) {
mpg_pin = &inputpin[i];
mpg_pin->bit = 1U << mpg_pin->pin;
PIO_Mode(mpg_pin->port, mpg_pin->bit, OUTPUT);
BITBAND_PERI(MPG_MODE_PORT->PIO_ODSR, MPG_MODE_PIN) = 0;
}
i++;
}
#endif

to:
uint32_t i = 0;
#ifdef MPG_MODE_PIN
// Pull down MPG mode pin until startup is completed.
while(mpg_pin == NULL) {
if(inputpin[i].id == Input_ModeSelect) {
mpg_pin = &inputpin[i];
mpg_pin->bit = 1U << mpg_pin->pin;
PIO_Mode(mpg_pin->port, mpg_pin->bit, OUTPUT);
BITBAND_PERI(MPG_MODE_PORT->PIO_ODSR, MPG_MODE_PIN) = 0;
}
i++;
}
#endif

I get it to compile.

I fixed this a few days ago but forgot to commit it as I have been busy with other issues. Will commit the fix later today.

Thanks, Terje.

I'm working up a machine map for RAMPS1.4 as well.
