Libreria PWM

Una duda, estoy probando la libreria <PWM.h> pero solo funciona con los pines 11 y 12, pero no con los demas, alguien le pasa lo mismo?

#include <PWM.h>
int32_t frecuencia =445;  //he variado int32, 8 y 16
int tiempo =150;
unsigned long inicia =0;

int led =12;  //en este y 11 perfecto en 6,7,8,9,10 no funciona
int brillo =0;
int fade =-1;

void setup()
{  InitTimersSafe();
 bool suceso = SetPinFrequencySafe(led, frecuencia);
void loop()
 pwmWrite(led, brillo);
} (13.3 KB)

The Arduino has 3Timers and 6 PWM output pins. The relation between timers and PWM outputs is:

Pins 5 and 6: controlled by timer0
Pins 9 and 10: controlled by timer1
Pins 11 and 3: controlled by timer2

On the Arduino Mega we have 6 timers and 15 PWM outputs:

Pins 4 and 13: controlled by timer0
Pins 11 and 12: controlled by timer1
Pins 9 and10: controlled by timer2
Pin 2, 3 and 5: controlled by timer 3
Pin 6, 7 and 8: controlled by timer 4
Pin 46, 45 and 44:: controlled by timer 5

Si usas Timer0 modificas millis()

Veo comandos para cada timer en tu librería, mira los ejemplos.

La librería en un ejemplo dice:

float GetPinResolution(uint8_t pin)
Returns the same value as TimerX_GetResolution(), but takes a pin number
as a parameter so that the caller is timer agnostic.

There are several things to keep in mind when trying to optimize resolution:
-pwmWriteHR() is only useful for 16 bit timers, since 8 bit timers are inherently limited to 8 bit pwm
-The higher the frequency, the lower the resolution. pwmWriteHR() will automatically map input to the
actual timer resolution
-Resolution can be optimized in this way for 2 pins on the Uno (9 and 10), and 11 pins on the Mega (2,
3, 5, 6, 7, 8, 11, 12, 44, 45, and 46)

si en mi mega solo 11 y 12 voy a probar metodo manual
