B.4 Installing the FTDI Device Driver for USB Connections
The first time that you make a USB connection between your PC and a kit component
which features the FTDI FT232 chip, you may be prompted to install the device driver
for the chip on your PC. This driver is provided in the toolchain JN-SW-4041 but not in
JN-SW-4141 - for the latter, you will need to obtain the driver from the Internet.
Using JN-SW-4041
The installation of the driver from the JN-SW-4041 toolchain is described below
(although you will not need this procedure if Windows automatically finds the required
driver on the Internet).
1. When you make the USB connection, check whether Found new hardware
wizard for TTL232r-3v3 is displayed on your PC.
If this appears, you must install the driver by following the rest of this procedure.
Otherwise, the driver is already installed.
2. Fill in the screen Install from a specific location , as follows:
a) Select the radio button Search for the best driver in these locations .
b) Tick the checkbox Include this location in the search .
c) Using the Browse button, navigate to the directory FTDI_drivers in the
installed SDK on your PC. If the SDK has been installed on drive C of your
PC, the path will be:
C:\Jennic\Tools\Drivers\FTDI_drivers
d) Click OK .
The wizard will automatically fill in the details in the drop-down search box.
3. In the Found new hardware wizard screen, click Next .
4. Wait for the wizard as it searches for and installs the new driver. On
completion, it will display the message "Completing the Found new hardware
wizard". Click
Finish to complete.
In some cases, you may need to repeat the procedure from Step 2, depending
on your hardware configuration.
Finally, the Found new hardware bubble will indicate that the hardware is
installed and ready for use.
Using JN-SW-4141
If using the JN-SW-4141 toolchain, you must obtain the driver for your operating
system from the VCP drivers page of the FTDI web site:
www.ftdichip.com/Drivers/
VCP.htm . Download the required driver to your desktop and double-click on its icon
to install. To perform the installation, a device or cable containing an FTDI chip must
be connected to a USB port of your PC .
Note: Alternatively, you can obtain the driver from the
FTDI web site, as described below for the

JN-SW-4141 toolchain.
