Follow these steps to download and
configure the DLPC44xx GUI:
- Download and install the associated Firmware SW package. The
Projector Control (.projector) and Firmware binary (.img) files are located in
the install directory. The same procedure applies to the other supported DMDs
within the appropriate firmware install directory.
- Setting up Communication Preferences:
- DLPC44xx GUI supports USB and I2C communication. To
change these settings, please go to Edit-
>Preferences->Communication.
- For USB, select the USB interface.
Note: USB is the preferred method to download the
firmware flash image to the projector as USB is much faster than
I2C.
- An error message can appear
saying the USB driver cannot be opened. This is expected, as TI has not
yet enabled communication on the board. Click OK on this error.

Projector Control
Configuration:
- Run the DLPC44xx GUI tool and select the Projector
Control sub-tool.
- Select Open Projector File then select
Add. Navigate to the .projector file location installed in
step 1.
- Make sure the desired
Projector Control File is checked, then select OK.
Note: If the user wants to use one Projector
Control file at a time, then de-select the files to hide before
selecting OK.
- Once this file is loaded, the user can navigate through
the pages to control a DLPC4430 controller.
- Flash Loader Configuration:
- Select the Flash Loader sub-tool, then select the
Browse button. Navigate to the .img file installed in Step 1
and select Open.
- Select Complete Image Download if this is the
first time download. The flash has the boot loader pre-loaded; uncheck
the Skip Boot Loader Area.
Note: Check Skip Boot
Loader Area only if you need to upgrade the
bootloader.
- Connect DLPC4420AEVM to PC via USB. Make sure USB communication
capability by clicking Reset Bus on the bootloader menu in the
DLPC44xx GUI. The Status field looks as follows:
Note: If there is
an issue with USB communication, then turn off DLPC4430EVM and
disconnect then reconnect USB cable and power on board.
- Select Start Download to begin. The loading
process takes about 2 minutes.
- After the download has completed, switch SW1 to
OFF and switch the power to the unit under test (UUT) off.
Remove the jumper on J8 from the DLPC4430EVM board.
- After removing the jumper, re-enable power to the
DLPC4430EVM. Switch SW1 to the “On” position. A Red LED appears after a
few seconds. The Red LED shuts off and a green LED begins blinking.
After the blinking LED appears, the DLP Texas Instruments logo is
visible on the DMD for a few seconds. The DMD appears as seen in Figure 3-13:
Turn the switch back to the OFF
position before connecting the USB cable to DLPC4430EVM. The power supply does not
have to be disconnected before connecting the USB cable. Once the USB cable is
connected to the DLPC4430EVM (and the PC), turn the switch on the DLPC4430EVM to the
“on” position.
