| 17 | ##### How to use this driver #####
|
---|
| 18 | ==============================================================================
|
---|
| 19 | [..]
|
---|
| 20 | The PCD HAL driver can be used as follows:
|
---|
| 21 |
|
---|
| 22 | (#) Declare a PCD_HandleTypeDef handle structure, for example:
|
---|
| 23 | PCD_HandleTypeDef hpcd;
|
---|
| 24 |
|
---|
| 25 | (#) Fill parameters of Init structure in HCD handle
|
---|
| 26 |
|
---|
| 27 | (#) Call HAL_PCD_Init() API to initialize the PCD peripheral (Core, Device core, ...)
|
---|
| 28 |
|
---|
| 29 | (#) Initialize the PCD low level resources through the HAL_PCD_MspInit() API:
|
---|
| 30 | (##) Enable the PCD/USB Low Level interface clock using
|
---|
| 31 | (+++) __HAL_RCC_USB_OTG_FS_CLK_ENABLE();
|
---|
| 32 | (+++) __HAL_RCC_USB_OTG_HS_CLK_ENABLE(); (For High Speed Mode)
|
---|
| 33 |
|
---|
| 34 | (##) Initialize the related GPIO clocks
|
---|
| 35 | (##) Configure PCD pin-out
|
---|
| 36 | (##) Configure PCD NVIC interrupt
|
---|
| 37 |
|
---|
| 38 | (#)Associate the Upper USB device stack to the HAL PCD Driver:
|
---|
| 39 | (##) hpcd.pData = pdev;
|
---|
| 40 |
|
---|
| 41 | (#)Enable PCD transmission and reception:
|
---|
| 42 | (##) HAL_PCD_Start();
|
---|
