nsyskbd.rpl is the system library that allows applications to use USB keyboards plugged in the WiiU USB ports; it supports up to multiple keyboards and assign a channel to each keyboard connected.
Functions
Initialisation
| Prototype | Description |
|---|---|
uint8_t KBDSetup((void*)connection_callback,(void*)disconnection_callback,(void*)key_callback)
|
Initializes the USB keyboard library and set callbacks; return 0 if the library was successfully initialized. connection_callback is called when an USB keyboard is connected with an uint8_t* as argument that specify the channel that was assigned to the keyboard. disconnection_callback is called when an USB keyboard is disconnected with an uint8_t* as argument that specify the channel of the keyboared that was disconnected. key_callback is called when a key event happens (press/release) and has a pointer to a key_state structure as argument |
uint8_t KBDTeardown()
|
Deinitializes the USB keyboard library and return 0 if the deinitialization was successfull |
uint8_t KBDInit((void*)unknown,(void*)connection_callback,(void*)disconnection_callback,(void*)key_callback);
|
Pass arguments to KBDSetup (probably an old function left for compatibility); should returns 0 if successfull |
uint8_t KBDExit();
|
Calls KBDTeardown() (probably an old function left for compatibility); should returns 0 if successfull |
Structures
| Prototype | Description |
|---|---|
typedef struct {
uint8_t ch; //Key channel
uint8_t scancode; //Key scancode
uint32_t state; //1=pressed; 0=releases; 3=keeping pressed
uint8_t unknown[4]; //?
uint16_t UTF16; //Pressed char value in UTF16
} key_state; |
Used as argument of key_callback |
