Hello,
On my regular Arduino I have running a processes under the Timer-Interrupt.
At a frequentie of 200 Hz my routine is updating ISR(TIMER1_COMPA_vect). See my
code below.
How can I activate this kind of process in amForth?
I appreciate all help.
Cheers,
Jan
void setup() {
noInterrupts();
TCCR1A = 0;
TCCR1B = 0;
TCNT1 = 0;
/* Set timer values */
long f=200; /*200 Hz*/
long value = 16000000/256/f;
OCR1A = (int)value ;
TCCR1B = 0b00001100;
TIMSK1 = 0b00000010;
interrupts();
}
ISR(TIMER1_COMPA_vect)
{
/*per interrupt wordt een van de vier 7-segment display's
aangestuurd. Oog kan deze snelle verandering niet volgen.
Komt de refresh onder de 150 hz gaan ze flikkeren
*/
WriteValueToSegment(idx, SEGMENT_MAP_DIGIT[Seven_segment_display[idx]]);
idx += 1;
if (idx > 3)
idx = 0;
}
