DESCRIPTION =========== This example project shows how to use the IAR Embedded Workbench for ARM to develop code for the Atmel AT91SAM9261 evaluation boards. It shows basic use of parallel I/O, Timer and the interrupt controller. It starts by showing different patterns on the LED s separated by half second. COMPATIBILITY ============= The project is compatible with the AT91SAM9261-EK board.

watchdog,中文名稱叫做“看門狗”，全稱watchdog Timer,從字面上我們可以知道其實(shí)它屬于一種定時(shí)器。

freescale MCF5485EVB開發(fā)板上中斷操作示例，利用一個(gè)Timer產(chǎn)生中斷，另外3個(gè)Timer作為GPIO，使3g個(gè)LED每隔1秒鐘輪換亮一次。

As you have learnt that sleep( )/usleep()/nanosleep() are not good to delay a process. Timers can provide more accurate time control in applications. In this lab, you will explore POSIX Timers and signal programming, experience the Timer drift. The primary focus of this lab will be "time". The experiment will show you several methods to measure time in your applications.

Hello User This is nothing, but a simple program which if kept in start of windows will shut down the system by itself within five minutes of starting. It takes the time from the system & starts its Timer to shut down after 5 minutes (not considering seconds). U can use shutdown.exe,once started there is only one exit that u know only. EXIT : DOUBLECLICK TIME TO ENABLE EXIT
