PMIC_ERR PMICGetFreqAsync(u16* freq, PMICCallback cb, void* arg);

Arguments

freq Location for storing the sampling frequency of the audio data received from the Wii Speak.
cb Callback function that will send notification of the execution results of this function.
arg Passed as the second argument of the callback function above.

Return Values

Returns one of the following.

PMIC_ERR_OK The function has been called normally.
PMIC_ERR_INVALID_ARGUMENTS The correct argument was not passed.
PMIC_ERR_INVALID_STATE The Wii Speak is not open.
PMIC_ERR_BUSY Cannot register the command. Call the function again.

Description

Asynchronously gets the sampling frequency of the audio data received from the Wii Speak.

This function stores the obtained sampling frequency at the address specified by the freq argument. The function stores PMIC_FREQ_8KHZ for a sampling frequency of 8000 Hz; PMIC_FREQ_11KHZ for a sampling frequency of 11,025 Hz; or PMIC_FREQ_16KHZ for a sampling frequency of 16,000 Hz. The default sampling frequency is PMIC_FREQ_16KHZ.

One of the following is passed to result, the callback function's first argument.

PMIC_ERR_OK The sampling frequency has been successfully obtained.
PMIC_ERR_NO_DEVICE The Wii Speak has been unplugged.
PMIC_ERR_INVALID_STATE The Wii Speak is not open. (Confirm that the Wii Speak cable is inserted in the USB port.)
PMIC_ERR_USB_ERROR An error occurred in USB communications. Call the function again.
