This firmware translates a PS/2 mouse to a USB mouse. The translator firmware is entirely interrupt driven (with the exception of sending the data via USB to the host.) An interrupt is generated when the PS/2 start bit is received, at which time the firmware will begin its receive routine. In addition to this interrupt, every 168ms a timer overflow interrupts the main program and implements one state of the mouse state machine. This state machine handles sending bytes to and translating bytes received from the PS/2 mouse automatically. All of this is done in the background while the main program runs in the foreground. The only operation that the main program implements is sending mouse data to the PC via USB.

This class implements the same API as the Java 1.3 java.util.TimerTask. * Note that a TimerTask can only be scheduled on one Timer at a time, but * that this implementation does not enforce that constraint.

// This program measures the voltage on an external ADC input and prints the // result to a terminal window via the UART. // // The system is clocked using the internal 24.5MHz oscillator. // Results are printed to the UART from a loop with the rate set by a delay // based on Timer 2. This loop periodically reads the ADC value from a global // variable, Result.

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
