* @brief Speeduino main file containing initial setup and system loop functions
|
|
* @author Josh Stewart
|
|
*
|
|
* This file contains the main system loop of the Speeduino core and thus much of the logic of the fuel and ignition algorithms is contained within this
|
|
* It is where calls to all the auxilliary control systems, sensor reads, comms etc are made
|
|
*
|
|
* It also contains the setup() function that is called by the bootloader on system startup
|
