Totally PO’d…

Halfway through exams now, with three to go. Tomorrow brings a Java exam, Friday a C/C++ and Tuesday sports a Physics exam. I’m very shaky on the latter, so I’m doing a lot of studying up this week.

Some happy news. Thanks to a rather generous soul, Adam Eberbach, who rather liked my tutorials I wrote about AVRs, I’ll soon be the proud owner of a PoScope. It’s no replacement for a real high-bandwith scope, but it’s neat none-the-less. It’s suitable for audio-signal analysis, but also (what I’m really looking forward to) for logic analysis at 8MHz. I’d tossed up previously between trying to get a logic analyzer and trying to get a scope, but this way I’ll be able to have my cake and analyze it too.

Denver Gingerich, the man behind the MyUSB keyboard demo, has sent me a new patch for a magnetic stripe card reader. It’s now included in the MyUSB source code. Built on the keyboard demo, the project enumerates as a standard USB keyboard, and transmits read card data as a 1-0 ASCII stream over to the computer. He’s also got a nice support page set up for it, located here. Oh, and a blog post about it, too.

I’m slowly working on the host code. I’ve been fixing a number of bugs with the library, and currently the plugged-in device is just returning a USB Setup Stall request in response to my GetDescriptor control request. Further work is needed to debug the problem and get the code working. Still, at least it is being worked on. Stay tuned!
