DlnPwmGetFrequency() Function

The DlnPwmGetFrequency() function retrieves the current PWM frequency.

Syntax

C/C++

DLN_RESULT DlnPwmGetFrequency(
  HDLN handle, 
  uint8_t port,
  uint8_t channel,
  uint32_t* frequency,
);

Parameters

handle: A handle to the DLN-series adapter.
port: A number of the PWM port.
channel: A number of the PWM channel.
frequency: A pointer to an unsigned 32-bit integer that receives the current frequency setting for the DLN-series adapter.

Return Value

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

Remarks

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