USBMSCHFatFsTiva.h File Reference

Detailed Description

USBMSCHFatFs driver implementation for a Tiva USB controller used with the USBMSCHFatFs driver.

============================================================================

The USBMSCHFatFs header file should be included in an application as follows:

#include <ti/drivers/USBMSCHFatFs.h>
#include <ti/drivers/usbmschfatfs/USBMSCHFatFsTiva.h>

Refer to USBMSCHFatFs.h for a complete description of APIs & example of use.

This USBMSCHFatFs driver implementation is designed to operate with a Tiva' USB library. Only 1 instance of the USBMSCHFatFsTiva driver is supported.

intPriority is the USB peripheral's interrupt priority, as defined by the underlying OS. It is passed unmodified to the underlying OS's interrupt handler creation code, so you need to refer to the OS documentation for usage. For example, for SYS/BIOS applications, refer to the ti.sysbios.family.arm.m3.Hwi documentation for SYS/BIOS usage of interrupt priorities. If the driver uses the ti.drivers.ports interface instead of making OS calls directly, then the HwiP port handles the interrupt priority in an OS specific way. In the case of the SYS/BIOS port, intPriority is passed unmodified to Hwi_create().
