This file implements the mass storage class example.
requirement zcu102 board in usb device mode, connected with host using USB 3.0 cable
Following other files require to run this example o xusb_ch9.c, xusb_ch9.h o xusb_freertos_ch9_storage.c, xusb_freerots_ch9_storage.h o xusb_freertos_class_storage.c, xusb_freertos_class_storage.h
o on success example will be detected as mass storage on host o do IN and OUT transfer of the same size o must not get diff between IN and OUT files

void BulkInHandler | ( | void * | CallBackRef, |
u32 | RequestedBytes, | ||
u32 | BytesTxed | ||
) |
This function is Bulk In Endpoint handler/Callback called by driver when data is sent.
CallBackRef | is pointer to Usb_DevData instance. |
RequestedBytes | is number of bytes requested to send. |
BytesTxed | is actual number of bytes sent to Host. |
void BulkOutHandler | ( | void * | CallBackRef, |
u32 | RequestedBytes, | ||
u32 | BytesTxed | ||
) |
This function is Bulk Out Endpoint handler/Callback called by driver when data is received.
CallBackRef | is pointer to Usb_DevData instance. |
RequestedBytes | is number of bytes requested for reception. |
BytesTxed | is actual number of bytes received from Host. |
int main | ( | void | ) |
This function is the main function of the USB mass storage example.
None. |
void SetupInterruptSystem | ( | struct XUsbPsu * | InstancePtr, |
u16 | UsbIntrId | ||
) |
This function setups the interrupt system such that interrupts can occur.
This function is application specific since the actual system may or may not have an interrupt controller. The USB controller could be directly connected to a processor without an interrupt controller. The user should modify this function to fit the application.
InstancePtr | is a pointer to the XUsbPsu instance. |
UsbIntrId | is the interrupt ID of the USB controller |
