Part 3 HDMI Display Module Program
Description
We provide the HDMI driver programs of ALINX Series FPGA
development board. In these driver demos, the FPGA drives the output
display of SiI9134 by Internally generating HDMI timing and testing data.
The different resolution of testing image can be generate by modifying
9/13
HDMI Display Module AN9134 User manual
www.alinx.com
the output clock timing of HDMI. Press the button KEY1 to switch the
testing images. The function diagram of the testing programs (Figure
3-1) as below:
Figure 3-1: The function diagram of the testing programs
Below is the brief instruction to the functions of each module
used in the FPGA driver programs
1. mv_pattern.v
This module is used to generate different testing images and
HDMI Vertical/ Horizontal sync signals. It generated 7 patterns
testing images, included 8-color horizontal strip, 8-color vertical bar,
scrolling gradient, black and white square, all blue, color gradient,
frame. The Vertical/ Horizontal sync signals of HDIM generated by
the parameter defined by TOP layer, that are the timing required by
HDMI.
2. ax_debounce.v
This module is used to detect the action of press the button,
detect the falling edged of button. The function of button debounce

is also added in the programs.
3. i2c_config.v
This module is used to registers the SiI9134 chip by calling the
I2C communication module，the configured register address and
value are defined in the lut_9134.v file. The specific registers
meaning, please refer to the instruction manual of SiI9134 chip.
4. reset_power_on.v
This modules is used to generate a software reset to initialize others
modules after power-on.
Part 4 Hardware connection and Testing
The hardware connection between the AN9134 module and FPGA
development are easy. The 40-pin female headers of module plug into the
expansion board of FPGA development kit, and then connect the HDMI
connector to the monitor. The figure 4-1 is the expansion IOs J1 of ALINX
Series FPGA development kit AX301 and the AN9134 HDMI module
hardware connection as below: (if connected to the expansion IOs J2, need
to re-assign the pins)
