startPulses(Pin, Frequency, Precision) function starts the train of pulses at the specified frequency and precision. The default frequency is 1kHz and the default precision is 3.
startPulses(3, 2000, 3);
stopPulses function stops the train of pulses.
On ARDBOX Analog it is possible to use this functions in outputs:
– TIMER0: Q0.1 and Q0.6
– TIMER1: Q0.2 and Q0.3
– TIMER3: Q0.5
On MDUINO-21, MDUINO-42 and MDUINO-58 it is possible to use this functions in outputs:
– TIMER0: Q0.5 and Q2.6
– TIMER1: Q2.5 – TIMER2: Q1.5 (Multiply the frequency x2)
– TIMER3: PIN2, PIN3 and Q0.6
– TIMER4: Q0.7, Q1.6 and Q1.7
– TIMER5: Q1.3, Q1.4 and Q2.0
IMPORTANT: It is not possible to have different frequencies between the same Timer Pin’s. Some outputs share the same timer, so they work at the same frequency.
CAUTION!!! When the Timer0 pins are used, all the time functions change their functionality as
delayMicroseconds() and others.
Next it is showed recommended precision between different frequencies:
Precision = 1: from 30Hz to 150Hz
Precision = 2: from 150Hz to 500Hz
Precision = 3: from 500Hz to 4kHz
Precision = 4: from 4kHz to 32kHz
Precision = 5: from 32kHz to 4MHz
To have a HIGH precision on the desired frequency, it is recommended to use the closer precision to the values of the previous table.
