NANO-14

On Johannes le Roux's GitHub site, you will find all the elements needed to build an "Ardu14".

Arduino-Nano MK-14

NANO-14

I adapted the "Ardu14.ino" source code to allow the use of a Nano board with a "terminal" program (TeraTerm, Hyperterm, etc.) on a PC.

The board alone, without 7-segment LED displays or push-buttons, thus allows the use of programs written in SC/MP assembly language.

This version includes :

Help on commands,

Loading programs in «Intel Hex» format,

Step-by-step program scrolling ("Space" key),

Either Uppercase / Lowercase can be used.

Of course, the NANO-14 works perfectly with a compatible Nano board (less than €3) which is more economical than a real Arduino Nano (around €28)!

Plus a small printed, laminated box to finish it all off...

NANO-14 Plus

I also adapted the "Ardu14.ino" source code to allow the same Nano—now equipped with a MAX7219 7-segment display—to be used with a PC "terminal" program (such as TeraTerm or Hyperterm).

The board, with its 7-segment LED display, thus enables the use of SC/MP assembly language programs that display text on the LEDs.
At address 0F20, a preloaded demonstration program uses this feature.
