#include <revolution/pmic.h> PMIC_ERR PMICOpen(void);

Returns one of the following.
PMIC_ERR_OK |

|---|---|
PMIC_ERR_NO_DEVICE |

PMIC_ERR_INVALID_STATE |
Either the PMIC library is not initialized, or the Wii Speak cable is not inserted in the USB port. |
PMIC_ERR_BUSY |

PMIC_ERR_USB_ERROR |

PMIC_ERR_FATAL |

Opens the Wii Speak synchronously.
If the Wii Speak is successfully opened, its microphone transitions to the stopped state. You can set operating parameters, start the microphone, and perform various other operations on the Wii Speak while the microphone is stopped.
The library prepares to recognize the Wii Speak by calling the PMICProbe function first after calling the PMICInit function. Therefore, after calling the PMICInit function, always call the PMICProbe function once before calling this function.
Also, even if the Wii Speak is connected, if you call this function before the library recognizes the Wii Speak and PMIC_ERR_OK is returned for the PMICProbe function, this function returns PMIC_ERR_INVALID_STATE (in rare cases, PMIC_ERR_BUSY). In such cases, call this function after waiting a while until the PMIC_ERR_OK value is returned for the PMICProbe function.
This function cannot be called in an interrupt handler or alarm callback.
After the Wii Speak is opened, the error notification callback registered by the PMICRegisterErrorCallback function is enabled.
Note: Do not quit an application while the Wii Speak is still open. Always call the PMICCloseAsync or PMICClose function to close the Wii Speak before exiting an application.
