FILES ------------------------------------------------------------------------- stm32lib/* - all the (possibly consolidated) stm32 lib and usb example code usb.c - USB-specific hardware setup. Interrupts, clocks, etc. handling USB when not "Attached". some low-level callbacks (low power mode, init, reset, resume, etc). usb_callbacks.c - aka endpoints: handling data transfer when "Configured". calls out to application specific callbacks (eg DFU or serial shit) usb_descriptor.c - aka application descriptor; big static struct and callbacks for sending the descriptor. main.c - main loop and calling any hardware init stuff. timing hacks for EEPROM writes not to block usb interrupts. logic to handle 2 second timeout then jump to user code. hardware.c - init routines to setup clocks, interrupts, also destructor functions. does not include USB stuff. EEPROM read/write functions. dfu.c - mostly the giant FSM case switch, also some USB endpoint callbacks TODO -------------------------------------------------------------------------- * tap reset then quickly tap The Button leaves the board in dfu wait loop forever instead of just 2 seconds * use sizeof() for usb application descriptor
