DlnPwmGetMaxFrequency() Function

The DlnPwmGetMaxFrequency() function retrieves the maximum possible value of the PWM frequency.

Syntax

C/C++

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

Parameters

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

Return Value

DLN_RES_SUCCESS (0x00): The function successfully retrieved the maximum possible 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 DlnPwmGetMaxFrequency() function is defined in the dln_pwm.h file.
