I've made some progress on the LED module. The wiki provides a source download for the LED. What I didn't realize is that this is *not* the code you call to talk to the LED. The code on the wiki page does that. The code you download is to run *on* the LED module itself, since it contains a tiny Arduino itself with hard coded firmware.
This is a cool system because it lets the LED module handle animation while your main code works on something else. The downside is that this firmware is limited and buggy. In particular the LED shield will always print '05' sideways after your command requests are complete.
If there was a way to reflash the LED shield then we could fix this firmware and add new features, like sideways numbers and setting individual pixels. Any ideas on how we can do this? The LED module does have some exposed pads on the circuit board that have tiny scratches on them. I think these were used to original flash the module at the factory. Hopefully we can reflash it at home too.
Any official thoughts from the SeeedStudio team?
