Using Tiva C as a usb device in NI LabVIEW

Hello Mesut,

There are no plans for TI to develop such a driver for TivaWare.

I need USB RAW device driver.

You don't need any specific PC driver for LabView USB RAW device.
USB RAW stands on built-in WinUSB driver.
Just provide this interface GUID by MS OS descriptor, or by WinUSB INF file.
{761ED34A-CCFA-416b-94BB-33486DB1F5D5}

Searching for this interface GUID, LabView (NI VISA) driver should capture your device as USB RAW


1) Using WinUSB device
In this post, I explained about how to convert TivaWare usb_dev_bulk into WinUSB device.

"WinUSB Device" implementation for Tivaware
https://e2e.ti.com/support/microcontrollers/tiva_arm/f/908/p/481401/1734782

In the attached zip file on above post, add this line to usbdMSdesc.c

#define USB_NI_LABVIEW_USB_RAW_IF_GUID    L"{761ED34A-CCFA-416b-94BB-33486DB1F5D5}"

Also, replace USB_TI_USB_DEV_BULK_IF_GUID to USB_NI_LABVIEW_USB_RAW_IF_GUID in this line

static tMS_EXTENDED_PROPERTY_DESCRIPTOR g_USBExtendedPropIfGUIDDesc =
{
    .header    = MS_EXTENDED_PROPERTY_HEADER( sizeof( tMS_EXTENDED_PROPERTY_DESCRIPTOR ), 0x0001 ),
//  .property0 = MS_EXTENDED_PROPERTY_INTERFACE_GUID( USB_TI_USB_DEV_BULK_IF_GUID )
    .property0 = MS_EXTENDED_PROPERTY_INTERFACE_GUID( USB_NI_LABVIEW_USB_RAW_IF_GUID )
};

And then, follow the instruction on above post, to make up the firmware.


2) Using INF file
Modify usb_dev_bulk.inf (under \TivaWare_C_Series-2.1.2.111\windows_drivers\) at this line

[Dev_AddReg]
;; HKR,,DeviceInterfaceGUIDs,0x10000,"{6E45736A-2B1B-4078-B772-B3AF2B6FDE1C}"
HKR,,DeviceInterfaceGUIDs,0x10000,"{761ED34A-CCFA-416b-94BB-33486DB1F5D5}"

[ Edit ] The interface GUID value was wrong at the first post,

right one for USB RAW is, {761ED34A-CCFA-416b-94BB-33486DB1F5D5}

{A5DCBF10-6530-11D2-901F-00C04FB951ED}  is for NI USBTMC
