- Use this board as an all-in-one display driver for TTL displays
- Designed as a small, easy to use display driver for Adafruit's 40-pin TTL displays
- Will decode any resolution from 25-165MHz pixel clock, basically up to 1080p
- Power the display and decoder from a USB port
It's a mini HDMI decoder board! So small and simple, you can use this board 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 a beefy 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. We've used this breakout with 800x480 displays, so we have not specifically tested it with higher resolutions. We added a bunch of supporting circuitry like a backlight driver and configured it for running basic TTL display panels such as the ones we have in the shop
You can even power the display and decoder from a USB port. If you want more backlight control, there's a PWM input, connect that to your microcontroller or other PWM output and you can continuously dim the backlight as desired.
The USB port then acts as both power and data, with the touch screen appearing like a USB mouse. We've tested it sucessfully on Mac, Windows, and Debian Linux (Raspbian on a Raspberry Pi). Other Linux distributions may or may not work, but if you're running Linux you're probably used to that.
