mbed_official 237:f3da66175598 19 [..]
mbed_official 237:f3da66175598 20 The PCD HAL driver can be used as follows:
mbed_official 237:f3da66175598 21
mbed_official 237:f3da66175598 22 (#) Declare a PCD_HandleTypeDef handle structure, for example:
mbed_official 237:f3da66175598 23 PCD_HandleTypeDef hpcd;
mbed_official 237:f3da66175598 24
mbed_official 237:f3da66175598 25 (#) Fill parameters of Init structure in HCD handle
mbed_official 237:f3da66175598 26
mbed_official 237:f3da66175598 27 (#) Call HAL_PCD_Init() API to initialize the HCD peripheral (Core, Device core, ...)
mbed_official 237:f3da66175598 28
mbed_official 237:f3da66175598 29 (#) Initialize the PCD low level resources through the HAL_PCD_MspInit() API:
mbed_official 237:f3da66175598 30 (##) Enable the PCD/USB Low Level interface clock using
mbed_official 237:f3da66175598 31 (+++) __USB_CLK_ENABLE);
mbed_official 237:f3da66175598 32
mbed_official 237:f3da66175598 33 (##) Initialize the related GPIO clocks
mbed_official 237:f3da66175598 34 (##) Configure PCD pin-out
mbed_official 237:f3da66175598 35 (##) Configure PCD NVIC interrupt
mbed_official 237:f3da66175598 36
mbed_official 237:f3da66175598 37 (#)Associate the Upper USB device stack to the HAL PCD Driver:
mbed_official 237:f3da66175598 38 (##) hpcd.pData = pdev;
mbed_official 237:f3da66175598 39
mbed_official 237:f3da66175598 40 (#)Enable HCD transmission and reception:
