This would have to "bit-bang" the DLP-IO8 interface in order to drive the typical 44780 interface on an Optrex LCD. Does openwrt have Perl or Python or something available?

I may try to build an internet radio, but replace the Atmega business with this <a HREF="http://www.dlpdesign.com/usb/io8.shtml" rel="nofollow">DLP-IO8 USB to 8 i/o</A> interface. This would allow the openwrt Linux to directly drive an LCD, plus with an analog input, it should be able to read the "tuning" potentiometer directly. The DLP-IO8 is made by dlpdesign.com, available from Digikey.com for about $30. Jeff, this is impressive. . . but it seems overkill to use another micro to supply
