Currently, FFUART (the console) and STUART are what's available (from the gumstix) on the robostix. The tweener also make FFUART available. However, since the tweener has all of the signals going from the top to the bottom of the board, you can tap into any of the signals there by soldering a 30 gauge wire-wrap into one of the vias. This would allow access to the other serial ports. -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/ |
