|
- ##### How to use this driver #####
|
|
|
- ==============================================================================
|
|
|
- [..]
|
|
|
- The PCD HAL driver can be used as follows:
|
|
|
-
|
|
|
- (#) Declare a PCD_HandleTypeDef handle structure, for example:
|
|
|
- PCD_HandleTypeDef hpcd;
|
|
|
-
|
|
|
- (#) Fill parameters of Init structure in HCD handle
|
|
|
-
|
|
|
- (#) Call HAL_PCD_Init() API to initialize the HCD peripheral (Core, Device core, ...)
|
|
|
-
|
|
|
- (#) Initialize the PCD low level resources through the HAL_PCD_MspInit() API:
|
|
|
- (##) Enable the PCD/USB Low Level interface clock using the following macro
|
|
|
- (+++) __HAL_RCC_USB_CLK_ENABLE(); For USB Device FS peripheral available
|
|
|
- on STM32F102xx and STM32F103xx devices
|
|
|
- (+++) __HAL_RCC_USB_OTG_FS_CLK_ENABLE(); For USB OTG FS peripheral available
|
|
|
- on STM32F105xx and STM32F107xx devices
|
|
|
-
|
|
|
- (##) Initialize the related GPIO clocks
|
|
|
- (##) Configure PCD pin-out
|
|
|
- (##) Configure PCD NVIC interrupt
|
|
|
-
|
|
|
- (#)Associate the Upper USB device stack to the HAL PCD Driver:
|
|
|
- (##) hpcd.pData = pdev;
|
|
|
-
|
|
|
- (#)Enable HCD transmission and reception:
|
|
|
- (##) HAL_PCD_Start();
