//Digital ignition system for a car.//

===== Changelog =====
**Status: ** //Done, depricated.//

===== About =====
A replacement ignition system, for older cars with mecanical ignition system, for dynamicly changing the ignition angle depending on the RPM. 

===== Hardware =====
{{:hardware:ignition_dev_top.jpg?320|Development board}} A controller, PIC16F877, is messuring time between pulses from a HAL-sensor placed at the motor's axis and calculates the RPM. Depending on the RPM, it waits a certain amount of time before it creates a pulse out to a MOSFET ignitioning the ignintion coil.\\ 

{{:hardware:ignition_dev.jpg?320|Development setup}} In a four cylinder engine, two MOSFET's are needed.\\ 

===== Software =====
{{:hardware:ignition_software.jpg?320|Software}} PC software written in Visual Basic 6 for realtime changeing and saving delay time for quantified RPM levels. Also able to view current RPM.

===== Schematics =====
N/A

===== Firmware =====
The firmware is written in HI-TECH PICC using MPLAB.
