Functional Description
The AmPLink USB Adapter provides SPI, I2C and GPIO interfaces to the AmP evaluation board. The SPI bus is used to
control the AmP device and program both AmP and flash memory. The I
2
C bus provides control and monitoring of the
power supply functions of the AmP device. GPIO is used for evaluation board configuration and to support functions on
the SPI interface. All pins use 3.3V logic except where otherwise stated.

Precautions for Use
The AmPLink USB Adapter features ESD protection, however, damage may occur at high ESD levels. Therefore, it is
recommended that static handling precautions be followed at all times.
Software
AmPLink software is only intended for use with AnDAPT products. It can be downloaded from
https://www.andapt.com/
WebAmP AmPLink download.
Windows Driver Installation
The AmPLink Adapter drivers will normally be installed automatically when an Adapter is plugged into a USB port on a
PC. If this does not happen use the driver setup executable available from the FTDI website at
http://www.ftdichip.com/Drivers/D2XX.htm.
Choose the latest version based on your operating system.
Windows AmPLink Control Installation
The control software is available at
https://www.andapt.com/
WebAmP tools download page.
Download the zip file to your PC and unzip the AmPLink.zip folder onto your hard disk. Click on the executable to run the
Windows control interface.
