bogdanm 0:9b334a45a8ff 17 ##### How to use this driver #####
bogdanm 0:9b334a45a8ff 18 ==============================================================================
bogdanm 0:9b334a45a8ff 19 [..]
bogdanm 0:9b334a45a8ff 20 The PCD HAL driver can be used as follows:
bogdanm 0:9b334a45a8ff 21
bogdanm 0:9b334a45a8ff 22 (#) Declare a PCD_HandleTypeDef handle structure, for example:
bogdanm 0:9b334a45a8ff 23 PCD_HandleTypeDef hpcd;
bogdanm 0:9b334a45a8ff 24
bogdanm 0:9b334a45a8ff 25 (#) Fill parameters of Init structure in HCD handle
bogdanm 0:9b334a45a8ff 26
bogdanm 0:9b334a45a8ff 27 (#) Call HAL_PCD_Init() API to initialize the HCD peripheral (Core, Device core, ...)
bogdanm 0:9b334a45a8ff 28
bogdanm 0:9b334a45a8ff 29 (#) Initialize the PCD low level resources through the HAL_PCD_MspInit() API:
bogdanm 0:9b334a45a8ff 30 (##) Enable the PCD/USB Low Level interface clock using
bogdanm 0:9b334a45a8ff 31 (+++) __USB_CLK_ENABLE);
bogdanm 0:9b334a45a8ff 32
bogdanm 0:9b334a45a8ff 33 (##) Initialize the related GPIO clocks
bogdanm 0:9b334a45a8ff 34 (##) Configure PCD pin-out
bogdanm 0:9b334a45a8ff 35 (##) Configure PCD NVIC interrupt
bogdanm 0:9b334a45a8ff 36
bogdanm 0:9b334a45a8ff 37 (#)Associate the Upper USB device stack to the HAL PCD Driver:
bogdanm 0:9b334a45a8ff 38 (##) hpcd.pData = pdev;
bogdanm 0:9b334a45a8ff 39
bogdanm 0:9b334a45a8ff 40 (#)Enable HCD transmission and reception:
bogdanm 0:9b334a45a8ff 41 (##) HAL_PCD_Start();
