ATTiny2313 controls Numitron tube

in code, how-to by the machinegeek | 0 comments


Kenneth Finnegan has posted details on controlling Numitron tubes using the ATTiny2313 MCU. Numitron tubes are filament display devices which require only 2-3 volts instead of the much higher voltages required by Nixie tubes and VFDs. He uses an Allegro A6278 LED driver (which he found in his parts collection and no longer manufactured, but any constant-current driver will work). He wrote a simple piece of code that cycles through all the digits 0-9.

Further details, schematic and code can be found on Kenneth’s blog.
