![]() It uses NewSoftSerial on pins 2 and 3 as well as regular serial on pins 0 and 1 (on old Arduino0022) just for testing to see if NewSoftSerial is any good. I have a simple Arduino sketch that just shows each character. ![]() The module asserts the busy line when it is working but it is enough to just make short delays in your code! The module has a single 20 pin connector (2x10 0.1" pins) of which we only need connection for +5V, GND, serial data in and a busy line out. I've put a Xino into the box and I'm working on something amusing for it to do in the hackspace. can be operated by a parallel interface or a synchronous serial interface. It has a European font with characters in the range from 0x20 (space) through the ASCII range and up to 0xFF with a bunch of Greek and Cyrillic characters. Futaba Vacuum Fluoresc ent Display Module M204SD08AA, with Fut aba VFD. So VFD Tubes are much safer and easier to handle. ![]() The russian IV-11 Tubes used in this tutorial need 25V, while Nixie tubes need around 170-200V. ![]() The Futaba Corp M202SD08G module is a 20 character x 2 line, 5x8 dot matrix display. Set of 6 IV-11 VFD Tubes Advantage of VFD Tubes against Nixie Tubes Unlike Nixies, VFDs work with a relatively low anode voltage. It is housed in a project box with a mains transformer - it use to have a mystery 9-pin serial port input but it wouldn't work until we worked out that it was expecting a 5V TTL serial signal. A small Vacuum Flourescent Display I recovered from the skip at work.
