I updated it one kernel rev so I could use cheap Chinese USB-Ethernet adapters. I actually am not sure what kernel this is, anymore.
I found that some libraries and/or include files are not there to map the OMAP hardware registers in the Angstrom distro I had at the time, but they are present in this Debian install. I take control of the GPIO port mapping registers and then access the GPIO directly from user mode C code. > > I'm not sure your assessment of Tk/Tcl is correct---already a decade > ago, my ace programmer turned out terrific interactive displays > including live dial gauges and temperature bars, moving 3D > representations of machine controls, etc., using an amalgam of Tk/Tcl > and VRML(!).

I am eager to have an alternative to it. Constructing complex GUIs in Tk/Tcl is a horrible exercise, and each GUI page often runs to thousands of lines of Tcl code, with all sorts of annoying problems. One that I've never found a fix for is the GUIs just take up too many screen pixels. > I look forward to hearing about your successes using Glade. > Well, I re-did the simple GUI in modern glade, and adapted a Python script from Chris Morley to work with it. It mostly works, after less than one day tinkering! One thing I still haven't figured out is how to make text from the Python appear in a textbox on the GUI. Then, the next big job is leaning how to attach this as a front-end to a C program. So far, I'm doing all this on an Ubuntu 10.04 PC system, no need to add the Beagle's complexity until I know what I'm doing at this level. Another thing that pointed me in this direction was somewhere I saw that you could turn a local Python script into a web server with just an option on the command line when you start it. Haven't tried that, yet.
