6 Quick-Start Procedure

This quick-start assumes the default EVM condition as shipped.

  1. In case a Raspberry PI is available, proceed with connecting the DLPDLCR230NPEVM to the Raspberry PI. Ensure that the Raspberry Pi has been setup as described in Section 9. If the Raspberry PI is currently not needed, proceed with step 2.

  2. Power up the DLP LightCrafter Display 230NP EVM by applying an external DC power supply (5-V DC) to the JPWR1 connector. The D_P5V LED will indicate that the 5-V DC power supply has been applied to the system.

    TI used following power supply for this EVM : ME30A0503F01.


    External Power Supply Requirements:
    • Nominal Output Voltage: 5 VDC
    • Minimum Output Current: 4 A
    • Efficiency Level: VI
    • Output Connector: Barrel Plug, 2.5 mm I.D. × 5.5 mm O.D. × 9.5 mm
    NOTE: TI recommends using an external power supply that complies with applicable regional safety standards such as UL, CSA, VDE, CCC, PSE, and so forth.
  3. The system will automatically drive Proj-ON high when the 5-V DC power supply is applied and the fan is plugged in. If the fan is not plugged in or a loose connection is present Proj-ON will not be driven high. The DLPDLCR230NPEVM includes a input voltage monitor which drives Proj-ON low if the input voltage drops below approximately 4.65 V for any reason during operation.
  4. After the DLP LightCrafter Display 230NP EVM is turned on; the projector will default to displaying a DLP logo followed by a LightCrafter Display test pattern image. The D_HOST_IRQ will be OFF which indicates a successful boot of the DLPC3436. The D_DONE and D_INIT_B will be ON to indicate a successful boot-up of the FPGA.

  5. The focus of the image can be adjusted manually on the optical engine.

  6. Ensure that Raspberry has been configured correctly as described in Section 9 before applying power to the Raspberry PI via the USB Type C cable.
  7. Power down with the Raspberry PI connected:
    • Drive PROJ_ON LOW via Raspberry PI GPIO 25 (refer to Section 9)
    • Shutdown the Raspberry PI (refer to Section 9)
    • Remove power from the Raspberry PI by removing the USB Type C cable
    • Remove the power adapter to the DLPDLCR230NPEVM
  8. Power down without Raspberry PI connected:
    The projector can be turned off by just removing the power cable. A voltage monitor on the EVM will detect the input voltage go below approximately 4.65 V and will drive Proj-ON low automatically.

There are five indicator LEDs on the DLP LightCrafter Display 230NP EVM, and they are defined in Table 6-1:

LED Reference Signal Indication Description
D_HOST_IRQ HOST_IRQ ON during DLPC3436 boot, OFF when projector is running. Indication of DLPC3436 boot-up completed and ready to receive commands
D_PROJ_ON PROJ_ON PROJ_ON signal is HIGH
D_INIT_B INT_B ON when FPGA initialization is completed. OFF indicates that the FPGA is in RESET or a configuration error occurred.
D_DONE DONE ON when FPGA configuration is completed.
D_P5V P5V Input voltage 5 V applied
