DlnPwmGetDutyCycle() Function

The DlnPwmGetDutyCycle() function retrieves the current PWM duty cycle value.

Syntax

C/C++

DLN_RESULT DlnPwmGetDutyCycle(
   HDLN handle, 
   uint8_t port,
   uint8_t channel,
   double* dutyCycle
);

Parameters

handle: A handle to the DLN-series adapter.
port: A number of the PWM port.
channel: A number of the PWM channel.
dutyCycle: A pointer to the double precision floating point number that receives the current duty cycle.

Return Value

DLN_RES_SUCCESS (0x00): The function successfully retrieved the current duty cycle value.
DLN_RES_INVALID_PORT_NUMBER (0xA8): The port number is not valid. Use the DlnPwmGetPortCount() [1] function to find the maximum possible port number.
DLN_RES_INVALID_CHANNEL_NUMBER (0xC0): The channel number is not valid. Use the DlnPwmGetChannelCount() [2] function to find the maximum possible port number.

Remarks

The DlnPwmGetDutyCycle() function is defined in the dln_pwm.h file.
