1 millisecond Timer

1 millisecond Timer is similiar to GPT but ticks only every 1 millisecond. It does not have any restriction or conflicts with PWM pins. It allows to measure relatively big delays to control time critical processes as well as contolling servo motors. To set up a user handler function use ZUNO_SETUP_ISR_1MSTIMER macro to as describted here.

ZUNO_SETUP_ISR_1MSTIMER(m1ms_handler);

unsigned long count_1ms = 0;

void m1ms_handler() {
    count_1ms++;
}

void setup() {
    Serial.begin(115200);
}

void loop() {
    Serial.println(count_1ms);
    delay(1000);
}
