Header board for direct attached pixels
« on: July 29, 2015, 07:03:49 AM »
Has anyone created a header board (cape) for Pi or BBB to make it easier to do direct attached Pixels?

Is this a trick question? F4-B or F16-B for the BBB.  :) 

There isn't anything for the Pi yet although I think Mat was looking at creating a board to allow attaching ws2801 pixels to the Pi.

+1 on the F4-B and F16-B.  These two Capes are about as easy and inexpensive as a Pixel Controller can get. The F16-B can easily be expanded to  F48-B status if you add two extension boards.

They are just for 3-wire style strings, though. I have heavily tested with TM-1804 and TM1809 chipsets.

For 4-wire and a larger selection of pixel types, you'll need the Falcon F16V2

Not really a trick question. I thought that we were able to connect 1 string to the Pi. So I was looking for something likt the P10 pannel header you created for the Pi.  Just a simple /  inexpensive alternative to the other 2 boards,

I like the FPD, but was looking for something a little more low-key without the need for dongles and controllers.

Is an option but not sure the limitations

I am not sure of Mat's current plans but a board for the Pi would be pretty simple to do if he isn't planning on it anymore.

What's the pinout for direct attached pixels?

check the built in FPP help page for the Channel Outputs screen, it has pinouts for WS2801 and WS281x pixels for their respective channel outputs on the PI.
