Digital Tachometer using PIC16F628A on Honda Twister

Tachometer on Honda CB Twister 110 using 3x 7-segment multiplexed led displays and a PIC16F628 microcontroller. Uses the capture feature to count the number of spark firings on the alternator's CDI ignition signal generator line and does some maths to calculate the engine RPM and display on the leds.. uses multiplexed display technology for minimal wires, engine on/off display detecting the signals, clips the extra zero to show values like 1.2 instead of 01.2, has 2 leds for mileage speed and hi speed indicators and a startup sequence pattern test..
