One good way to address this and other such possibilities would be to start de-soldering each component that is not strictly necessary to drive the OLED. Do them one at a time, and test between each one. Sounds like a fun way to spend an afternoon. If you have a spare board and components, it might be easier to start from scratch, and add one thing at a time. (Which would also help catch bad solder joints.) If you get down to just the CPU, OLED, and required support components, I would go so far as to remove the CPU and its required components, and solder on wires to drive the OLED from off-board. Then you'd have it pretty well narrowed down, I'd say. -- Randall _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
