32.2 PCD Firmware driver API description
32.2.1 How to use this driver
The PCD HAL driver can be used as follows:
1. Declare a PCD_HandleTypeDef handle structure, for example: PCD_HandleTypeDef
hpcd;
2. Fill parameters of Init structure in HCD handle
3. Call HAL_PCD_Init() API to initialize the PCD peripheral (Core, Device core, ...)
4. Initialize the PCD low level resources through the HAL_PCD_MspInit() API:
a. Enable the PCD/USB Low Level interface clock using
__HAL_RCC_USB_OTG_FS_CLK_ENABLE();
__HAL_RCC_USB_OTG_HS_CLK_ENABLE(); (For High Speed Mode)
b. Initialize the related GPIO clocks
c. Configure PCD pin-out
d. Configure PCD NVIC interrupt
5. Associate the Upper USB device stack to the HAL PCD Driver:
