/* Simple simulator for Kinetis KL25Z MCU
 * Main include file.
 * Include just this file in your source.
 * Requires C++11 support.
 *
 * Note: to simulate switch input use pinRead() with SW1 - SW4;
 * Keyboard key '1' is SW1, SW2 is key '2' etc.
 * Pressing a key toggles the switch On/Off.
 * So use '1' and '1' to simulate switch SW1 press and release.
 * This is because holding the key down results in the char being sent
 * repeatedly to the program - keyboard has autorepeat feature.
