mbed_official 235:685d5f11838f 17 ##### How to use this driver #####
mbed_official 235:685d5f11838f 18 ==============================================================================
mbed_official 235:685d5f11838f 19 [..]
mbed_official 235:685d5f11838f 20 The PCD HAL driver can be used as follows:
mbed_official 235:685d5f11838f 21
mbed_official 235:685d5f11838f 22 (#) Declare a PCD_HandleTypeDef handle structure, for example:
mbed_official 235:685d5f11838f 23 PCD_HandleTypeDef hpcd;
mbed_official 235:685d5f11838f 24
mbed_official 235:685d5f11838f 25 (#) Fill parameters of Init structure in HCD handle
mbed_official 235:685d5f11838f 26
mbed_official 613:bc40b8d2aec4 27 (#) Call HAL_PCD_Init() API to initialize the PCD peripheral (Core, Device core, ...)
mbed_official 235:685d5f11838f 28
mbed_official 235:685d5f11838f 29 (#) Initialize the PCD low level resources through the HAL_PCD_MspInit() API:
mbed_official 235:685d5f11838f 30 (##) Enable the PCD/USB Low Level interface clock using
mbed_official 613:bc40b8d2aec4 31 (+++) __HAL_RCC_USB_OTG_FS_CLK_ENABLE();
mbed_official 613:bc40b8d2aec4 32 (+++) __HAL_RCC_USB_OTG_HS_CLK_ENABLE(); (For High Speed Mode)
mbed_official 235:685d5f11838f 33
mbed_official 235:685d5f11838f 34 (##) Initialize the related GPIO clocks
mbed_official 235:685d5f11838f 35 (##) Configure PCD pin-out
mbed_official 235:685d5f11838f 36 (##) Configure PCD NVIC interrupt
mbed_official 235:685d5f11838f 37
mbed_official 235:685d5f11838f 38 (#)Associate the Upper USB device stack to the HAL PCD Driver:
mbed_official 235:685d5f11838f 39 (##) hpcd.pData = pdev;
mbed_official 235:685d5f11838f 40
mbed_official 613:bc40b8d2aec4 41 (#)Enable PCD transmission and reception:
