+
+  EXAMPLE DESCRIPTION
+  
+  Program toggles onboard LED with 1 Hz frequency. It uses timer, which is 
+  periodically read (1 ms) and if its value is higher than that of variable the
+  LED is toggled. After that variable is incremented so timer has not to be
+  reset.
+  
+*******************************************************************************/

+Timer tim; // Timer definition
+DigitalOut LED(LED1); // definition of digital out pin
+
+// returns Timer value
+int getTimerVal(Timer *tim) {
+    int time = tim->read_ms();
+    // reset when overflow
+    if (time<0){
+        tim->reset();
+        time = tim->read_ms();
