Topic: Chumby as controller for an LED cube
I am just building an RGB LED Cube an wonder if it is possible to use a Chumby as a controller for it. I need a fast SPI interface and additional 8 Bits of IO, maybe I can this reduce a bit.
Why use a Chumby, not an AVR or so: WLAN!
But the Chumby has not enough free IOs. But maybe it is possible do detach the display (an LED Cube does not need one) and use these pins as IO. But can the kernel boot without LCD or what is to do to free the LCDs pins from the kernel's use.
You may say: use the chumby hacker board. But to my opinion it is to expensive. For the same price as the hacker board plus WLAN stick I get a complete Chumby with Display, housing, ... And the hacker board is not available in Germany.
Another way is to add an AVR to the cube which does all that muxing stuff and a chumby connected via serial port to the AVR to write the images to the cube. But it has to be fast. At 20 fps I need about 380kbps on the serial port. Don't know if that is possible.
What do you think about my ideas?
