3.1.4 Programming the DLPC7540EVM and Displaying a SPLASH Image

Follow these steps to download and configure the DLPDLC-GUI for DLPC7540 operation:

  1. Download the DLPDLC-GUI and the Firmware SW package that includes the Firmware binary (.img) files for DLP471TE, DLP472TE, and DLP650TE.
  2. Install and open the DLPDLC-GUI
  3. Setting up communication preferences:
    1. DLPDLC-GUI supports USB and I2C communication. To change these settings in GUI, please go to Debug screen and select Connection tab.
    2. For USB, select the USB interface and click Connect; see Figure 3-3.
      Note: USB is the preferred interface to download the firmware flash image to the EVM as USB is much faster than I2C and does not require any additional hardware.

    3. Verify that EVM Status shown at bottom left of GUI says Connected, Bootloader Mode indicating you are ready to load image file into EVM.
  4. Flash Loader Configuration:
    1. Go to Firmware screen, select Update Firmware tab. Click on the folder icon to browse for the applicable firmware depending on the actual DMD that is connected to DLPC7540EVM. Once firmware image file is selected, click on Start Update; see Figure 3-4.
    2. Wait for the programming progress to indicate that firmware update is complete.
    3. Turn off the EVM by toggling the SW1 and SW5 switches in that order to off position. Remove the jumper from J9 and install back to J67.
    4. Turn on the EVM by toggling the SW5 and SW1 switches in that order to on position. After about 3 seconds, users see D5, D6, and D7 LEDs steadily on and D15 LED flashing. The DLP Texas Instruments logo is visible on the DMD; see Figure 3-5.

      Note:

      If there is an issue with USB communication, then turn off DLPC7540EVM and disconnect then reconnect USB cable and power on board.
