ST7565 Arduino Megajolt

Combining the ST7565 with an Arduino Nano and the Megajolt ignition in my 1970 Triumph Spitfire has produced a neat display for ignition tuning.

Arduino Megajolt LCD Display

This is my Mk2 version Megajolt in car display using the ST7565 LCD flat panel display. The LCD incorporates RGB LEDs for backlighting and by combining these we can generate almost any background colour. We will use this feature to act as a "shift light" or "Rev limit" indicator if you have these options set within the Megajolt.

Arduino based Megajolt In-Car Display

The plan here is to build a stand-alone unit that interrogates the megajolt ECU and displays the ignition advance setting, in degrees, and the inlet manifold pressure (Vacuum), in KPa.
These parameters may be monitored when using the megajolt-configuration-software but, using a laptop in the car while driving may not be entirely safe or convenient so this dedicated display was developed.
Apart from an interesting display there are some practical aspects to this project.
If you accelerate and the engine knocks (pinks), a glance at the ignition advance display will show the setting that must be adjusted.
Apart from that....I enjoy messing with this kind of stuff.
Based on the excellent Arduino board.
