Include to add

#include <MTobjects.h> // See http://arduino.dansetrad.fr/en/MTobjects

I strongly advise to leave the comment, if another person wanted to try the program, they would have a download link directly. This is valid for all the libraries you use.

These comments are words that can be added anywhere and which are ignored by the compiler.

Constructor

MThardPWM(pin, 
          periodMicrosecond = 20000 μs,
          inpulseMicrosecond = 10000 μs);

• pin (uint8_t): output pin; Uno/Nano: 9, 10 Mega: 2, 3, 5, 6, 7, 8, 11, 12, 13, 44, 45, 46
• inpulseMicrosecond (float): inpulse width in milliseconds
• periodMicrosecond (float): period in millisecondes, outputs (9,10), (2, 3, 5), (6, 7, 8), (11, 12, 13), (44, 45, 46) have the same frequency, eg change the frequency of the pin 7 also changes the frequency of pins 6 and 8 if they are used..

Useful functions

void setInpulse(float inpulseMicrosecond);
void setDutyCycle(float dutyCycle);
void setPeriod(float periodMicrosecond);
void detach(void);
void attach(void);

setInpulse: change the inpulse width
setInpulse: without parameter set inpulse width to 10ms
setDutyCycle: change the inpulse width with a duty cycle
setDutyCycle: without parameter set a 50% duty cycle 50%
setPeriod: change the period
setPeriod: without parameter set a 20ms period (50Hz)
detach: Disconnects the pin, it becomes "normal" as a starter (does not erase times programmed)
attach: Reconnect the pin, if it was detached

Bonus functions

float getInpulse(void);
float getPeriod(void);
float getDutyCycle(void);
float getResolution(void);

getInpulse: return the inpulse width
getPeriod: return the period
getDutyCycle: return the duty cycle
getResolution: returns the resolution in μs (between 62.5ns and 64μs)

Examples

• Example 1: Blinking of an LED
• Example 2: Flashing of an LED
