Nothing.

Initializes the PWM module with duty ratio 0. Parameter freq is a desired PWM frequency in Hz (refer to device data sheet for correct values in respect with Fosc).

This routine needs to be called before using other functions from PWM Remappable Library.

  Note :

• Before using this library, make sure that Peripheral Pin Select Library is checked in the Library Manager, and that appropriate pins were mapped.
• To select the desired PWM module, simply change the letter x in the prototype for the appropriate module number.

MCU must have Remappable CCP module.

  Note :

• Calculation of the PWM frequency value is carried out by the compiler, as it would produce a relatively large code if performed on the library level.
  Therefore, compiler needs to know the value of the parameter in the compile time. That is why this parameter needs to be a constant, and not a variable.

Initialize PWM module at 5KHz:

PWM4_Remappable_Init(5000);

Nothing.

Initializes the PWM module with custom parameters.

• PWM_Freq: desired PWM frequency in Hz (refer to device data sheet for correct values in respect with Fosc).
