| 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 | 235:685d5f11838f | 27 | (#) Call HAL_PCD_Init() API to initialize the HCD 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 | 235:685d5f11838f | 31 | (+++) __OTGFS-OTG_CLK_ENABLE()/__OTGHS-OTG_CLK_ENABLE(); |
| mbed_official | 235:685d5f11838f | 32 | (+++) __OTGHSULPI_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: |
