Adapter board with LVDS display for embedded applications that supply HDMI video output

The SEA0010 is a display format converter board that translates HDMI video output to LVDS. The board includes a 7" LVDS TFT Display with optional capacitive touch. The I²C capacitive touch screen controller signals are passed through to the host interface. The board is great for use with a Raspberry Pi (such as the Raspberry Pi 3 Model B or A+), or any single-board computer that provides an HDMI video output. There is a programmable on-board EEPROM that provides the HDMI video source with an EDID (the display resolution configuration).

Setup SEA00010 (PCAP) on Raspberry Pi

A quick overview on how to set up the SEA0010 HDMI converter with DT070DTFT-PTS on Raspberry Pi

Create a Raspbian Stretch Full SD card using Etcher
Modify /boot/config.txt to enable i2c and the 5 HDMI settings
Add these lines at the end of the file, to enable i2c, the PWM, and to set the LCD parameters:
```
- #SEACOMP demo
- dtparam=i2c_arm=on
- gpio=18=op,dh
- hdmi_force_hotplug=1
- hdmi_group=2
- hdmi_mode=87
- hdmi_cvt 1024 600 60 6 0 0 0
```
Connect all hardware together
Start up Raspberry Pi and go through the setup
Obtain the the touchscreen driver and Slideshow application onto a USB stick. Insert the USB stick, open file manager, open a command line, and run the setup

See this Raspberry Pi Getting Started doc.

PCAP driver directions for SEA0010 on Raspberry Pi

Building the Kernel

Follow Raspberry Pi website instructions for kernel development
- Download/install kernel headers
- Download other things (gcc? make?)
- Patch driver
- Make modules install
- Copy compiled module back over the one on the USB stick
To build the modified driver, apply the patch edt-ft5x06.patch to edt-ft5x06.c, then
```
make -j4 modules install
```
