Functions | |
| uint32_t | USBDeviceInit (usbGadgetObj_t *pUsbGadgetObj, char *pName) |
| This function initialises the USB gadget device object and then calls the init routine of the device controller which it represents. More... | |
| void | USBDInitCoreObject (void) |
| This API initialise the gadget list with the core objects available. | |
| uint32_t | USBDevEndpt0Handler (struct usbGadgetObj *pUsbGadgetObj, usbEndpt0event_t endptEvent, usbSetupPkt_t *pSetup) |
| This function handles the request EP0 requests which come from the lower layer driver. The protocol layer will interpret the setup packet and call the required function accordingly. More... | |
| void | usbEp0reqComplete (struct usbGadgetObj *pUsbGadgetObj, struct usbDevRequest *pReq) |
| This function handles the USB EP0 request complete. More... | |
| void | usbSetupEpReq (void *pUsbGadgetObj, uint32_t epNum, uint32_t *pUsbData, usbTokenType_t tokenType, uint32_t length, usbTransferType_t transferType) |
Variables | |
| static const pFnStdRequest | gUsbStdReqTable [] |
