Chapter 11: LPC13xx USB on-chip drivers
MscDevInfo.MSC_Write = MSC_MemoryWrite;
5. Initialize the USB:
DeviceInfo.DevType = USB_DEVICE_CLASS_STORAGE;
DeviceInfo.DevDetailPtr = (uint32_t)&MscDevInfo;
(*rom)->pUSBD->init(&DeviceInfo);
6. Initialize the mass storage state machine:
(uint32_t *) BulkStage = 0x10000054;
*BulkStage = 0x0;
7. Add the USB interrupt handler to your project:
USB_IRQHandler(void)
{
(*rom)->pUSBD->isr();
}
8. Call USB connect:
(*rom)->pUSBD->connect(TRUE);
11.4.2 USB human interface driver
The following steps show how to use the USB human interface driver. A complete
example is available in the LPC13xx code bundle.
1. Map the pointer to the on chip driver table:
ROM ** rom = (ROM **)0x1fff1ff8;
2. Enable 32-bit timer 1 (CT32B1) and IOCONFIG block:
LPC_SYSCON->SYSAHBCLKCTRL |= (EN_TIMER32_1 | EN_IOCON);
3. Initialize USB clock and pins:
(*rom)->pUSBD->init_clk_pins();
4. Set up device type and information:
USB_DEV_INFO DeviceInfo;
HID_DEVICE_INFO HidDevInfo;
HidDevInfo.idVendor = USB_VENDOR_ID;
HidDevInfo.idProduct = USB_PROD_ID;
HidDevInfo.bcdDevice = USB_DEVICE;
HidDevInfo.StrDescPtr = (uint32_t)&USB_StringDescriptor[0];
HidDevInfo.InReportCount = 1;
HidDevInfo.OutReportCount = 1;
HidDevInfo.SampleInterval = 0x20;
HidDevInfo.InReport = GetInReport;
HidDevInfo.OutReport = SetOutReport;
5. Initialize the USB:
DeviceInfo.DevType = USB_DEVICE_CLASS_HUMAN_INTERFACE;
