Fun with XC-2 network

Post by f_petrini »

Today I received five brand new XC-2 boards and created a sweet little network consisting of six XC-2 boards. (The sixth board is not shown in the picture)

Everything works great but I soon realized that managing six XTAGs (running code / flashing) is somewhat tiresome to do manually. ;)
I had to create a tool to automatically execute xrun/xflash targeting each board in sequence. It takes about 20 seconds to xrun all boards.
I tried to program the boards in parallel but that did not work well. Most of the time four or five out of the six xrun processes crashed so I guess it's not supported. :D

A client of mine is interested in using XMOS devices for a low-cost Ethernet hub. I got two XC-2s to check if it is feasible.

For the current project I'm feeding each board UDP packets containing 72 individual data streams (a total of ~5.2Mbit/s) which are output (async serial) on the 72 header pins. That's a total of 432 serial channels... 8-)

I've got to ask, why do you need 432 serial channels?

Close... It's for three 10x10x10 cubes. ;)

The cube design has 10 LEDs on each channel so (only) 10*10*3 channels are needed but the boards and software handles the full 430 channels without problems.
