TFP401 HDMI/DVI Decoder to 40-Pin TTL Breakout is a small and simple HDMI decoder board. It can be used as an all-in-one display driver for TTL displays, or perhaps decoding HDMI/DVI video for some other project. This breakout features the TFP401 for decoding video, and for the touch version, an AR1100 USB resistive touch screen driver.
The TFP401 is an advanced DVI/HDMI decoder from TI. It can take unencrypted video and pipe out the raw 24-bit color pixel data - HDCP not supported. It will decode any resolution from 25-165MHz pixel clock, basically up to 1080p.
There are two versions of TFP401 HDMI/DVI Decoder to 40-Pin TTL Breakout. One is video only and one is video + touch. This is the version with touch. Pair it with a screen that has a resistive touch overlay. The USB port then acts as both power and data, with the touch screen appearing like a USB mouse. The board is tested successfully on Mac, Windows, and Debian Linux (Raspbian on a Raspberry Pi). Other Linux distributions may or may not work.
This driver is designed specifically as a small and easy to use display driver for 40-pin TTL displays. In particular, it is suggested for use with single board computers with DVI/HDMI output like the Raspberry Pi or BeagleBone Black. You can power the driver over USB and then feed it video via the HDMI port. It's a very small board so great for tucking into an enclosure.
This board is shipped with an 800x480 resolution EDID so it will be auto-detected at that resolution. For advanced users, the EDID can be reprogrammed using Adafruit’s example Arduino code. Or, for computers that use Linux, you can always just force the resolution to whatever display you have connected.
Note: This is just a decoder board. A display is not included.
