preloads the Trion
®
T120 BGA324 Development Board with a simple example design
that sends color bars to an HDMI monitor at 1080p resolution. The T120 FPGA generates
an 8-color bar pattern, sends it to the LVDS-to-HDMI device on the board, and then to the
HDMI monitor for display.

Trion T120 BGA324 Development Board
HDMI Monitor
The example design uses the following hardware:
• Trion
®
T120 BGA324 Development Board
• 1080p monitor with HDMI connector
• HDMI cable
• 12 V power adapter
Set Up the Hardware
1. Attach standoffs to the board.
2. Connect the HDMI cable to the HDMI connector and to an HDMI-compatible monitor.
3. Connect the 12 V power cable to the board connector and to a power source.
4. Turn on the board's power switch.
Run the Example Design
After the FPGA configures, it outputs the color bars to the monitor.
The designs includes the
it6263_reg.mem file that contains the register mapping for the
1080p resolution. To use a different resolution, modify the register map file. Each line
represents the MSB or data.
• Line 1 is the the MSB of the 8 bit register.
• Line 2 is the data.
• Line 3 is the MSB of the next register, and so on
For example:
05
40
04
3D
04
1D
Lines 1 and 2 refer to register 05 and data 40.
Lines 5 and 6 refer to register 04 and data 1D.
