BML HDMI video for FPGAs over PMOD

Here are two open-source-hardware HDMI  video boards for adding digital video to FPGA platforms with standard PMOD connectors from Black Mesa Labs: The BML 3bit HDMI over single-PMOD uses 7 of 8 available LVCMOS 3.3 pins on a single PMOD to provide 3bit color ( R,G,B 100% On or Off ). Example Verilog design drives 800×600 […]

Using Tronsmart Pavo M9 for HDMI input streaming

Danman wrote: Thanks to a tip of my reader, I found a relatively cheap (69Eur) Android box with HDMI input and record ability. I thought that it should be possible not only to record the HDMI input but also to stream it in realtime so I ordered one for experimenting. Full details at Danman’s blog.

HDMI current booster fixes Raspberry Pi video instability

Orlando Cosimo with Creativity/Design blog was experiencing instability problems with the HDMI output on the Raspberry Pi which are typical when using an HDMI to VGA adapter. He devised this solution using three resistors and an LM317 voltage regulator. Orlando states, “This addon hardware extends a past project and it allow to increase the flow […]

A peek into the curious world of HDMI copy protection… with the Bus Pirate

Adam Laurie (a/k/a/ Major Malfunction) is a white hat hacker from London, UK, who has presented at a number of conferences worldwide. He’s also the Director at Aperature Labs, Ltd. Recently he explored the broken HDCP security mechanism used in HDMI. After building the HDMI breakout cable pictured above he examined the cable’s data lines […]

R-Pi as Arduino HDMI server

jokkebk over at Code and Life has developed a simple “HDMI server” for the Raspberry Pi that uses pyserial to receive commands over Pi’s serial interface, and pygame to display graphics primitives according to those commands. An Arduino client was written to send these commands to the Pi, drawing a string of blue rectangles to […]

Pipistrello: Spartan 6 development board with 64MB of RAM, High Speed USB, and HDMI

Magnusk designed the Pipistello Spartan 6 development board with the same IO headers as the Papilio One. It features 64MB of RAM running at 200Mhz, the FDTI FT2232H High Speed USB IC, HDMI output, and a micro-SD card holder. So the only option left was to make my own board – basically merging the FPGA […]
