Reading a VGA monitor’s configuration data with I2C and a PocketBeagle

Tuesday, March 27th, 2018

Ken Shirriff wrote an article showing how to read the monitor's config data using the I2C protocol and a board with an I2C port: Have you ever wondered how your computer knows all the characteristics of your monitor— the supported resolutions, the model, and even the serial number? Most monitors use a...

VGA framegrabbing with TVP7002

Thursday, February 13th, 2014

[embed]http://www.youtube.com/watch?v=8bmWkqSN7pw[/embed] desaster blogged about his VGA framegrabber project: The project got a nice boost when I found TVP7002 on TI’s site. It’s a video digitizing chip, featuring 3x ADC (one for each color channel) and a PLL system for generating the pixel clock from the HSYNC input. Compared to alternatives, this seemed...

7400 competition entry: Masochist’s video card

Monday, October 10th, 2011

Chris entered his Masochist's video card into the Open 7400 Logic Competition. Using only discrete logic his circuit cycles through 8 presettable colors at a variable frequency. Using a simple resistor network he outputs it over the VGA output. It is well documented and all the design files are available. Check...
