Each Kynar wire would be soldered to a classic 2.54mm female wire that can be plugged into the FT2232D, with the exception of bus pins you mention. > * Several pins on the LCD need to be connected to GND, and several LCD > pins need to be connected to the 3.3V power rail.

Simply by soldering the Kynar wires together, and then to a single 2.54mm wire to GND or 3.3V. > cathodes are brought out separately, and each needs its own series > resistor - a 120 ohm resistor between each LEDK pin and GND.

Well series resistors can be added to each Kynar wire, and then soldered to a single 2.54mm wire that will be connected to ground. > But if you think you can solve all of the above, I would GLADLY send > you one of these HaoRan LCD sample pieces plus an extra FT2232D board > (identical to the one I assume you already have for FCDEV3B UARTs) if > you can then send me back an assembled and working arrangement.

That's very doable, although I'd like to know the spacing between each pad on the flex connector. If the spacing is too small (like < 0.2mm) then I'm not sure I'm up to the task. --DS _______________________________________________ Community mailing list Community@freecalypso.org https://www.freecalypso.org/mailman/listinfo/community
