Overview
The Digilent JTAG-USB Full Speed module
provides a quick and inexpensive USB
programming solution for Digilent system
boards and supported JTAG devices. The
module works with any USB-equipped
computer and attaches to system boards using
a Digilent 6-pin JTAG header. A standard USB
A to Mini B cable is used to connect the
module to the PC.
In addition to the JTAG protocol, the module
also provides the ability to access SPI devices
via USB from a PC.
The JTAG-USB Full Speed module is ideal for
notebook computers or any computer without a
parallel port.
The module can communicate with JTAG and
SPI devices operating with I/O voltages from
1.5V to 3.
Features:
•
a Digilent 6-pin JTAG header
•
free JTAG programming software
(Adept v2.0 or higher)
•
compatibility with any USB port
•
USB A to Mini B cable included
Functional Description
JTAG-USB Full Speed provides an easy and
inexpensive USB connection. The Digilent
Adept application is needed for JTAG
programming. Adept automatically connects to
the module and detects devices in the JTAG
scan chain. For more information on using
Adept, see the Digilent Adept User’s Manual.
The module can also be used to program AVR
microcontrollers or communicate with some
Digilent Pmod modules using software freely
downloadable from the Digilent web site.
Every JTAG-USB Full Speed module is given a
unique serial number. The Adept software
uses this serial number to connect to the
device.
See the Digilent Adept User’s Manual for a
complete list of supported JTAG devices.
The Adept software and all support
documentation can be found on the Adept web
page at
