sahilmgandhi 18:6a4db94011d3 19 [..]
sahilmgandhi 18:6a4db94011d3 20 The PCD HAL driver can be used as follows:
sahilmgandhi 18:6a4db94011d3 21
sahilmgandhi 18:6a4db94011d3 22 (#) Declare a PCD_HandleTypeDef handle structure, for example:
sahilmgandhi 18:6a4db94011d3 23 PCD_HandleTypeDef hpcd;
sahilmgandhi 18:6a4db94011d3 24
sahilmgandhi 18:6a4db94011d3 25 (#) Fill parameters of Init structure in HCD handle
sahilmgandhi 18:6a4db94011d3 26
sahilmgandhi 18:6a4db94011d3 27 (#) Call HAL_PCD_Init() API to initialize the HCD peripheral (Core, Device core, ...)
sahilmgandhi 18:6a4db94011d3 28
sahilmgandhi 18:6a4db94011d3 29 (#) Initialize the PCD low level resources through the HAL_PCD_MspInit() API:
sahilmgandhi 18:6a4db94011d3 30 (##) Enable the PCD/USB Low Level interface clock using the following macro
sahilmgandhi 18:6a4db94011d3 31 (+++) __HAL_RCC_USB_CLK_ENABLE(); For USB Device FS peripheral available
sahilmgandhi 18:6a4db94011d3 32 on STM32F102xx and STM32F103xx devices
sahilmgandhi 18:6a4db94011d3 33 (+++) __HAL_RCC_USB_OTG_FS_CLK_ENABLE(); For USB OTG FS peripheral available
sahilmgandhi 18:6a4db94011d3 34 on STM32F105xx and STM32F107xx devices
sahilmgandhi 18:6a4db94011d3 35
sahilmgandhi 18:6a4db94011d3 36 (##) Initialize the related GPIO clocks
sahilmgandhi 18:6a4db94011d3 37 (##) Configure PCD pin-out
sahilmgandhi 18:6a4db94011d3 38 (##) Configure PCD NVIC interrupt
sahilmgandhi 18:6a4db94011d3 39
sahilmgandhi 18:6a4db94011d3 40 (#)Associate the Upper USB device stack to the HAL PCD Driver:
sahilmgandhi 18:6a4db94011d3 41 (##) hpcd.pData = pdev;
sahilmgandhi 18:6a4db94011d3 42
sahilmgandhi 18:6a4db94011d3 43 (#)Enable HCD transmission and reception:
