Digital Panel Design
Demonstration
This chapter illustrates how to exercise the digital panel reference design
provided with the kit. Users can follow the instructions in this chapter to build a 3.6
inch TV player (DE2 user only) and pattern generator using the DE2/DE1 in 5
minutes.
3-1Demonstration Setup
The Demonstration configuration is illustrated as Figure 3.1. The YUV 4:2:2 data
is sent from TV decoder to the cyclone II 2C35 FPGA. The FPGA on the
DE2/DE1 board is handling image processing part and set the LCD module
control register to display on the TRDB_LCM.

3-2Configuring the TV Player (DE2 User Only)
Locate the project directory from the CD-ROM included and follow the steps
below:
For DE2 boards with Serial Number (S/N) starting with Digit 0
Quartus II Project Directory: DE2_LCM_TV/For_DE2_SN_0X
For DE2 boards with Serial Number (S/N) starting with Digit 1
Quartus II Project Directory: DE2_LCM_TV/For_DE2_SN_1X
FPGA Bitstream Used: DE2_LCM_TV.sof or DE2_LCM_TV.pof
1. Ensure the connection is made correctly as shown in Figure 3.2. Make sure
the IDE cable is connected to JP1 of the DE2 board.
2. Download the bitstream (DE2_LCM_TV.sof/pof) to the DE2 board.
3. Connect a DVD player’s composite video output (yellow plug) to the Video-in
RCA jack of the DE2 board.
4. Press KEY0 on the DE2 board to reset the circuit.

3-3Configuring the Pattern Generator
Locate the project directory from the CD-ROM included and follow the steps
below:
For DE2 User:
Quartus II Project Directory: DE2_LCM_Test
FPGA Bitstream Used: DE2_LCM_Test.sof or DE2_LCM_Test.pof
For DE1 User:
Quartus II Project Directory: DE1_LCM_Test
FPGA Bitstream Used: DE1_LCM_Test.sof or DE1_LCM_Test.pof
1. Ensure the connection is made correctly as shown in Figure 3.3. Make sure
the IDE cable is connected to JP1 of the DE2/DE1 board.
2. Download the bitstream to the DE2/DE1 board.
3. Press KEY0 on the DE2/DE1 board to reset the circuit.
4. You can press SW0 and SW1 to switch to the other Pattern.
5. The following table summarize the functional keys of the this demonstration.
Switch Setting Function Description
SW[1:0] =[OFF,OFF] Gray bar.
SW[1:0] =[OFF,ON] Color bar.
SW[1:0] =[ON,OFF] 50% gray level pattern.
SW[1:0] =[ON,ON] White pattern.
