DlnPwmGetMinFrequency() Function

The DlnPwmGetMinFrequency() function retrieves the minimum possible value of the PWM frequency.

Syntax

C/C++

DLN_RESULT DlnPwmGetMinFrequency(
    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 minimum frequency value for the DLN-series adapter.

Return Value

DLN_RES_SUCCESS (0x00): The function successfully retrieved the minimum possible frequency 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 DlnPwmGetMinFrequency() function is defined in the dln_pwm.h file.
