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.
