AUTOMATE_PWM_INPUT( )
Congures a switch input to measure the duty cycle of a PWM signal applied to the input.
Syntax:
Automate_PWM_Input(sw#, Period_Ticks)
Parameters:
SW# A number 1 – 16 indicating which switch input of SW_1 to
SW_16 to measure the duty cycle.
Period_Ticks The Automate_PWM_Input function runs at a maximum 8ms
rate in the OS. This value is the expected period of the input
wavefore/8ms per measurement.
For example, if the PWM signal to be measured has a period of
200ms, the set the Period_Ticks to 200/8 = 25.
Set to 0 to disable the Automate_PWM_Input function.
Returns:
0 Function did not successfully execute.
1 Function successfully executed.
Error Codes:
BAD_ID
Switch # out of range.
The outputs of these functions are as follows:
Pwm_Input – The duty cycle of the PWM input. (0-32767 =
0-100% PWM)
SETUP_TIMER_LONG( )
Allows a 32-bit variable to be used to set the value of a timer with a single function call.
Syntax:
Setup_Timer_Long(TMR#, TIME)
Parameters:
TMR# ID of Timer to initialize (TMR1, TMR2, or TMR3).
TIME Reference to 32bit number, time in 0.1hr increments.
Returns:
0 Function did not successfully execute.
1 Function successfully executed.
Error Codes:
BAD_ID
TMR# out of range.
PARAM_RANGE parameter is out of range.
