LCD ARM board status update

After moving twice this summer, I finally got my workbench set up again (at least enough to start building stuff again). So I was able to build the latest version of the LCD ARM dev board ( It works fine and I think all the errors from the previous version are fixed. So I've attached the Eagle files and the BOM.

LED Video Wall


Several months ago, I was approached by the Portland band Starfucker (STRFKR) to build them an LED video wall for their upcoming tour. It needed to be large, bright, and durable, but also lightweight, portable, and easy to set up and tear down. They wanted to be able to plug in an iPod or iPad and play videos that are synced up along with their click track so everything goes along perfectly with the music. I enlisted the help of Alex Norman to take care of the software side of the project, and got to work trying to figure this thing out. It seemed like it could be made with mostly off-the-shelf components, and indeed that turned out to be the case. We decided that we would open-source the entire project, for the good of all mankind.

Not too long ago, I bought a small, inexpensive amplifier kit from tindie.

JTAG Nostalgia

JTAG adapter

Long story short: the GuruPlug JTAG wouldn't even debug the GuruPlug, let alone any other board I tried it with. I knew my freshly-compiled bleeding-edge OpenOCD was at least somewhat functional, because it was able to talk to my TI Evalbot through an onboard FTDI2232 USB-JTAG/UART chip. But it wouldn't talk to the FTDI2232 in the GuruPlug JTAG dongle.

ARM LCD Dev Board Eagle files

Recently I posted about the ARM based LCD development board I showed at a Monday DorkbotPDX meeting. At that time, I was waiting for another revision of the board before releasing the Eagle files. I got the next version back and it looks OK so I've attached the files.
The firmware source code is available on GitHub.
