3 TI ADC SPI Control Interface
3.1 Installing the ADC SPI Control Software
3.2 Using the TI ADC SPI Interface Software
TI ADC SPI Control Interface
This section describes the software designed to communicate with the ADC three-wire SPI interface. The
information is to be used in conjunction with the device data sheet, which explains the valid registers of
the device.
The ADC SPI control software can be installed on a personal computer by running the setup.exe file
located on the CD. This file installs the graphical user interface (GUI) along with the USB drivers needed
to communicate to the USB port that resides on the EVM. After the software is installed and the USB
cable has been plugged in for the first time, the user is prompted to complete the installation of the USB
drivers. When prompted, users should allow the Windows™ operating system to search for device drivers,
and it should automatically find the TI ADC SPI interface drivers. See Figure 2 .
Note: First-time operation: For proper installation of the necessary USB drivers, users should
install the accompanying software before connecting the USB cable to the EVM for the first
time. Not doing so could cause problems in communicating to the EVM.

Once the software is installed and the USB cable is connected, three primary modes of operating the
software are available: SPI register write, SPI register write using a script file, and ADS528X frequently
used registers.
