This quick-start assumes the default EVM
condition as shipped.
- 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.
- 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.
- 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.
- 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.
- The focus of the image can be adjusted
manually on the optical engine.
- 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.
- 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
- 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:
