HPWMOff

Syntax:

    HPWMOff ( channel, PWMHardware )

Command Availability:

Only available on Microchip PIC microcontrollers with PWM modules.

Explanation:

This command will disable the output of the PWM module on the Microchip PIC chip.

PWMHardware is a Great Cow BASIC defined constant not a user vaariable.

Example:

 'This program will alter the brightness of an LED using
    'hardware PWM.

    'Select chip model and speed
    #chip 16F18855, 32

    'Generated by PIC PPS Tool for Great Cow Basic
    '
    'Template comment at the start of the config file
    '
    #startup InitPPS, 85

    Sub InitPPS

            'Module: PWM6
            RA2PPS = 0x000E    'PWM6OUT > RA2

    End Sub
    'Template comment at the end of the config file


    'Set the PWM pin to output mode
    DIR PORTA.2 out

    'Main code
    For ForLoop = 1 to 4
        'Turn up brightness over 2.5 seconds
        For Bright = 1 to 255
            HPWM 6, 40, Bright, 2
            wait 10 ms
        next
        'Turn down brightness over 2.5 seconds
        For Bright = 255 to 1
            HPWM 6, 40, Bright, 2
            wait 10 ms
        next
    next

    HPWMOff 6, PWMHardware   'where PWMHardware is the defined constant or you can use TRUE
