    uint8_t* enabled
);

Parameters

handle

A handle to the DLN-series adapter.

A pointer to an unsigned 8-bit integer. The integer will be filled with the information whether the specified PWM port is activated. There are two possible values:

0 or DLN_PWM_DISABLED - PWM port is deactivated.
1 or DLN_PWM_ENABLED - PWM port is activated.

Return Value

DLN_RES_SUCCESS (0x00): The function successfully retrieved the PWM port state.
DLN_RES_INVALID_PORT_NUMBER (0xA8): The port number is not valid. Use the DlnPwmGetPortCount() function to find the maximum possible port number.
