If anyone has some real-world information on how these things perform
sending sync serial data with an external clock on something like a SS20,
I'd really like to know. Buffer size information would be especially
Putting together a project for Burning Man this year (www.burningman.com)
involving a SS20 or similar driving a very interesting kind of LED
display. Problem is, we need a time critical 2-4mbps sync serial data
rate and the onboard zs serial ports are barely capable of doing that
under ideal circumstances (tiny FIFOs). I can precalculate the data
stream by quite a bit so huge buffers and low interrupt overhead would be
Seems like I either need a HSSI card, an Ultra with se82532 serial ports
(which I wouldn't feel too great about lugging into the desert), or a
(hack ptooie) PC solution. Naturally I'd rather go all Sun. A PC laptop
would be great but I haven't seen many sync serial PCMCIA cards lately.
