EVM5509A USB Example
The USB example demostrates communication with the EVM5509A and computer.
In order to run the USB Example you must install the following software peices:
| For First Time Users |
Install the LibUsb-Win32 ( libusb-win32-filter-bin-0.1.8.0 ) drivers to the
c:\Program Files\LibUsb-Win32-0.1.8.0 |
Unzip the EMV5509A USB example code ( evm5509a_example_usb.zip ) to ( TI install directory )
c:\ti\boards\ |
Copy file: evm5509a_libusb.inf
c:\ti\evm5509a\examples\win32_usb\
to the LibUsb-Win32\bin directory
c:\Program Files\LibUsb-Win32-0.1.8.0\bin
Note:
evm5509a_libusb.inf contains information used to identify the EVM5509A's PID/VID IDs used in the usb examples |
Follow these steps to run the USB Exmaple:
Load Project
Open the usb.pjt Code Composer project using Project -> Open and selecting usb.pjt. It is in the directory
c:\ti\boards\evmdm642\examples\usb Load Program
Load the usb.out executable file. Select File -> Load Program. It will open a file browser dialog. Select the usb.out file in the usb\Debug directory in the file browser and hit "Open" to load the executable file. Run Program
Select the Debug -> Run option under the Debug menu. Connect USB
Connect the USB from the computer the the USB on the EVM5509A.
| For First Time Users |
Windows has no information about the EVM5509A prior to plugging in the usb cable, once connected the EVM5509A will send its PID/VID to Windows.
The PID/VID information matches the evm5509a_usblib.inf file above, and is what Windows uses to determine what type of usb device is connected. When the drivers window appears, point to the (LibUsb-Win32 install directory)\bin.

Run Win32 Program
Run packet.exe
c:\ti\boards\evmdm642\examples\win32_usb\packet.exe
This will send and receive packets of incrementing size between the Host computer & EVM5509A. Halt Program
When you are satisfied that the program is indeed running correctly, stop the program by selecting Debug -> Halt. At this time you can also disconnect the USB cable.
Windows Hardware Install Process
Upon connecting the EVM5509A for the first time, Windows will pop up a Found New Hardware window
Point to the LibUsb drivers located at the LibUsb-Win32\bin directory.
Continue installing if the driver doesn't pass the Windows Logo test.
Done installing the LibUsb-Win32 driver
