Detailed Description

Crank and Cam decoders

This file contains the various crank and cam wheel decoder functions. Each decoder must have the following 4 functions (Where xxxx is the decoder name):

triggerSetup_xxxx - Called once from within setup() and configures any required variables
triggerPri_xxxx - Called each time the primary (No. 1) crank/cam signal is triggered (Called as an interrupt, so variables must be declared volatile)
triggerSec_xxxx - Called each time the secondary (No. 2) crank/cam signal is triggered (Called as an interrupt, so variables must be declared volatile)
getRPM_xxxx - Returns the current RPM, as calculated by the decoder
getCrankAngle_xxxx - Returns the current crank angle, as calculated by the decoder
getCamAngle_xxxx - Returns the current CAM angle, as calculated by the decoder

Each decoder must utilise at least the following variables:

toothLastToothTime - The time (In uS) that the last primary tooth was 'seen'
