Interrupts can be an extremely efficient tool in the hands of the embedded-control programmer, to manage multiple tasks while maintaining precious timing and resources constraints. At the same time, they can be an extremely powerful source of trouble. The MPLAB C30 compiler helps manage the ...
In the previous method, adding new interrupts involved modifying the core interrupt service routine functions and adding functionality. One way to make this process easier is to employ interrupt vector tables, using C’s ability to take a pointer to a function. The developer writes the interrupt ...

In this case, we are using a hardware interrupt that is triggered by a state change on one of the digital pins. Most Arduino designs have two hardware interrupts (referred to as "interrupt0" and "interrupt1") hard-wired to digital I/O pins 2 and 3, respectively. The Arduino Mega has...
I am looking for a simple timer interrupt arrangement in my application. No hardware is involved, it's purely software.I have an application that runs on a Windows 2003 Server, written in C, developed in Visual Studio 2008. Without going into unnecessary detail, essentially, I require a ...
In system programming, an interrupt is a signal to the processor emitted by hardware or software indicating an event that needs immediate attention. An interrupt alerts the processor to a high-priority condition requiring the interruption of the current code the processor is executing. The processor...
Much more powerful projects can be achieved if we learn how to get around this by programming interrupts. An interrupt can be thought of like an alarm clock. You set the alarm clock, and then when the alarm goes off, no matter where your program is in the execution code, it stops what...
receiveC++function pointers. If you attempt to pass aC++function pointer to signal(), the compiler will flag it as an error. Therefore, to use the signal() function in theC++language, you must ensure that signal handler routines established have C linkage, by declaring them asextern "C". ...
