This file contains the lowl level USB driver routines. It constrols the USB serial interface engine, by managing the input and output transfers, and calling the defined callback function when required
http://www.usb.org ; for USB specifications http://www.lvr.com/usbc.htm ; a lot of information about USB http://www.beyondlogic.org/ ; also a nice with with useful information
No dependency found
usb_enable_module()
Procedure to turn on the USB device
usb_handle_stall()
Procedure can be called when the USB device has to be stalled
usb_setup()
Procedure to intialize the USB device, it will only do the setup, to enable the USB device, use the usb_enable() procedure
usb_handle_isr()
This is the heard of the USB library, all pending IO transfers are handled by this main (interrupt) service routine. For the PIC USB device it does not make much sense to use real interrupts since all real time aspects are handle by the SIE. Therefore this usb_handle_isr() must be polled on a regular base, in order to to keep the input and output transfers flowing
_usb_handle_standard_request()
Internal procedure to handle standard USB requests it will take care of the overall state of the device performing USB buffer management controlling the SIE and call the callback function if required
_usb_ints_on()
Internal procedure to set the correct interrupt flags, note that for PIC USB device it does not make much sense to use real interrupts since all real time aspects are handle by the SIE. However, the library does use the interrupt flags, this procedure will setup to proper interrupt flags
_usb_handle_transaction()
Internal procedure to handle the USB transactions it will take care of the overall state of the device performing USB buffer management controlling the SIE and call the callback function if required
_usb_handle_reset()
Internal procedure to reset the USB device
usb_is_configured() return bit
Function returns true if the usb device has been completely configured, otherwise return value will be false
usb_get_state() return byte
Get the state of the USB device USB_STATE_POWERED -> USB device is powered up, ready to start negotiating USB_STATE_DEFAULT -> USB device is now negotiating USB_STATE_ADDRESS -> USB device now has an address USB_STATE_CONFIGURED -> USB device is completely configured and ready to rock and roll
