SPI Interface

4 SPI Interface
This section describes the SPI control interface, installation of the GUI for SPI, and its usage. This EVM
can use SPI in two ways. One is through the TI ADC SPI Control Interface and another is using TI
TSW1200EVM Software 2.0. This section describes both methods in detail.
4.1

TI ADC SPI Interface

This section describes the software features of the EVM kit. The TI ADC SPI control software provides full
control of the SPI interface, allowing users to write to any of the ADC registers found in the data sheet.
For most ADS5400HFS/EM performance evaluations, users do not need to use the TI SPI control
software. They only need to use the ADC SPI control software when the desired feature is inaccessible
through the ADC parallel interface mode.
4.1.1 Installing the TI ADC SPI Interface
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 with the USB port that resides on the EVM. The software installation provides for installation
in a default directory, which the user may change to some other directory path if desired, as shown in
Figure 5. After the software is installed, insert the USB cable in the EVM to complete the installation. The
Found New Hardware wizard starts and when prompted, users must allow the Windows™ operating
system to search for device drivers by checking "Yes, this time only" as seen in
Hardware wizard automatically finds TI ADC SPI Interface drivers. When prompted that the TI ADC SPI
Interface has not passed Windows Logo Testing, select "continue anyway" as shown in
Figure 6. After completion, the TI ADC SPI Interface shows up in the Hardware Device Manager.
shows the SPI interface in the Hardware Device Manager which indicates that it is ready for use.
NOTE: Before plugging in the USB cable for the first time, install the TI ADC SPI software. The
