// 34 * This version of flash .c is for use on systems that have limited stack space
// 35 * and no display facilities. The complete version can be found in the
// 36 * Demo/Common/Full directory.
// 37 *
// 38 * Three tasks are created, each of which flash an LED at a different rate. The first
// 39 * LED flashes every 200ms, the second every 400ms, the third every 600ms.
// 40 *
// 41 * The LED flash tasks provide instant visual feedback. They show that the scheduler
// 42 * is still operational.
// 43 *
// 44 * The PC port uses the standard parallel port for outputs, the Flashlite 186 port
// 45 * uses IO port F and the AVR port port B.
// 46 *
