+// CooCox RTOS v1.1.4 with simple example
+// Two LEDs will blink with 250ms and 500ms interval based on two seperate tasks
+// by electronix79, 29/July/2011
+//
+// Comments: Nice work by Eric Ebert which used CooCox RTOS v1.1.3 but all files of CoOS were in one main folder,
+// so I create new project with the same structure as in CooCox design and of cause I use the updated version 1.1.4
