Interrupts are used to handle events that do not happen during the normal execution of a program, but when a specific trigger occurs. For example, if we write a program to blink an LED, the ...

This code example deals with the watchdog timer (WDT) of PSOC™ 4. The watchdog timer operates in two modes: the interrupt mode and the reset mode. In the interrupt mode, the LED toggles every second.

Just as you can often treat device registers as a memory-mapped struct, you can treat an interrupt vector as a memory-mapped array. In my last column, I suggested that you use casts sparingly and with ...

Consider a simple digital watch which is programmed to just show you time, now imagine you want to change its time zone. What would you do? You simply press a button ...

An ideal C++ device driver would be a class containing, among other things, the ISR as a member function. But this is harder to achieve than many C programmers assume. One of the goals of a recent ...

An increasing number of multi-threaded embedded applications want to leverage multicore designs. Symmetric Multiprocessing (SMP) RTOS provides automatic load balancing of multiple threads in a ...
