Introduction:
The methods described in this section allow the generation of Pulse
Width Modulation (PWM) signals. PWM signals enables the microcontroller to control
items like the speed of a motor, or the brightness of a LED or lamp.
The methods can also be used to generate the appropriate frequency signal to drive an
infrared LED for remote control applications.
GCBASIC support the methods described in this section.
Hardware PWM using a Timer/Counter with a OCRnx module
The AVR devices use a Timer/Counter and OCRnx module that has a variable period register. The Hardware PWM is available through the OCnx pin.
The method uses three parameters to setup the HPWM.
'HPWM channel, frequency, duty cycle HPWM 2, 100, 50
Relevant Constants:
A number of constants are used to control settings for PWM hardware module of the microcontroller. To set them, place a line in the main program file that uses #define to assign a value to the particular constant.
