****** Change PWM frecuency ARDUINO UNO*****
Function: setPwmFrequencyUNO(pin,divisor);
Description:
DO NOT MODIFY pin 6 is the one on which rely all time functions in Arduino: i.e.,
if you change the frequency of this pins, function like delay() or millis()
will continue to work but at a different timescale (quicker or slower!!!)
For pins 6 and 5: (5 and 6 are together, can not modify individually,same timer)
Divisor Frequency
1 62500 Hz
2 7812.5 Hz
3 976.5625 Hz <--DEFAULT Diecimila bootloader
4 244.140625 Hz
5 61.03515625 Hz
For pins 9, 10, 11 and 3: (9 & 10 and 11 & 3 are together,
can not modify individually,same timer)
Divisor Frequency
1 31372.55 Hz
2 3921.16 Hz
3 979.527 Hz
4 490.20 Hz <--DEFAULT Diecimila bootloader
5 244.882 Hz
6 122.55 Hz
7 30.610 Hz
****** Change PWM frecuency ARDUINO MEGA 2560*****
Function: setPwmFrequencyMEGA2560(pin,divisior);
This pins are together, can not modify frequency individually,same timmer):
pin 13, 4
pin 12, 11
pin 10, 9
pin 5, 3, 2
pin 8, 7, 6
For pins 13,4 (DO NOT MODIFY pins 13 & 4 is the one on which rely
all time functions in Arduino: i.e., if you change the frequency of this pins,
function like delay() or millis() will continue to work but at a different timescale
quicker or slower!))
