Dokumentation der Funktionen

void EVENT_USB_Device_ConfigurationChanged ( uint8_t  config)

Event when the USB configuration is changed. The configuration is stored in variable USB_Device_ConfigurationNumber

Definiert in Zeile 191 der Datei usb_cdc.c.

void EVENT_USB_Device_ControlOUT ( uint8_t *  data,
uint8_t  len 
)

Event when OUT data is received as part of a control transfer.

Definiert in Zeile 221 der Datei usb_cdc.c.

bool EVENT_USB_Device_ControlRequest ( USB_Request_Header_t *  req)

Event handler for the library USB Control Request reception event.

Definiert in Zeile 239 der Datei usb_cdc.c.

void EVENT_USB_Device_Reset ( void  )

Event when the host resets the device. Called after the library resets the control endpoint

Definiert in Zeile 215 der Datei usb_cdc.c.

bool EVENT_USB_Device_SetInterface ( uint8_t  interface,
uint8_t  altsetting 
)

Event when an alternate setting for an interface is selected. Return true to accept the alternate setting, or FALSE to send a STALL reply

Definiert in Zeile 183 der Datei usb_cdc.c.

void EVENT_USB_Device_Suspend ( void  )

Event when the USB bus suspends

Definiert in Zeile 201 der Datei usb_cdc.c.

void EVENT_USB_Device_WakeUp ( void  )

Event when the USB bus returns from suspend

Definiert in Zeile 208 der Datei usb_cdc.c.
