4.2 DLP Control Program
DLP Control Program for the DLP3021-Q1 allows users to use the FTDI cable to issue commands to the FPGA
via SPI to read/write registers, enable video playback, change videos, read DMD temperature via the TMP411,
or adjust current levels to the LEDs.
To change the DLP Control Program window and pages for DLP3021LEQ1EVM support, navigate to
Product →
Dynamic Ground Projection for Automotive
in the menu bar.
4.2.1 Connection
The first step in running the GUI requires the user to establish connection to the FTDI cable. The GUI will
attempt to automatically connect to the FTDI cable at start-up. To manually connect the FTDI cable, navigate to
the
Connection
page. With the FTDI cable selected from the drop-down interface list, click the
Connect
button.
Note, the Connection settings must be a clock rate of 5 MHz and timeout of 500 ms. When using the Cheetah™
interface, the clock rate can be increased to 16 MHz in SPI Mode 0 and MSB first bit order.
