Prototype
sub procedure PWM16bit_Change_Duty(dim duty as word, dim channel
as byte)
as byte)
Returns
Nothing.
Description
Changes PWM duty ratio. Parameter
duty
takes values shown on the table
below. Where 0 is 0%, and TOP value is 100% duty ratio. Other specific values
for duty ratio can be calculated as
for duty ratio can be calculated as
(Percent*TOP)/100
.
Requires
PWM module must to be initialised (PWM16bit_Init) before using
PWM_Set_Duty function.
PWM_Set_Duty function.
Example
Example lets set duty ratio to :
PWM16bit_Change_Duty( 300, _TIMER1_CH_A )
