Whether you're using only static memory, a simple stack, or dynamic allocation on a heap, you have to proceed cautiously. Embedded programmers cannot afford to ignore the risks inherent in memory utilization.

Memory leaks can be particularly risky for long-running embedded systems. Here are some tools to identify, track, and analyze memory leaks in embedded C and C++ programs.

To keep a watchdog timer from resetting your system, you've got to kick it regularly. But that's not all there is to watchdog science. We will examine the use and testing of a watchdog, as well as the integration of a watchdog into a multitasking environment.

Whether you are creating an operating system, firmware, or even device drivers, the way you write the software could affect the power consumption of the resulting product. Here are four approaches to minimizing power consumption through software.

The limitations of an 8-bit microcontroller (MCU) can sometimes make conventional C constructs produce suboptimal code. In this article we look at common problems on the 8051 family and discuss workarounds in C.

Language specifications, including those for C and C++, are often loosely written. A static analysis tool called lint can help you find dangerous and non-portable constructs in your code before your compiler turns them into run-time bugs.

Embedded software developers operate in a perfect digital environment but must interact with the imperfect analog real world. To do this it's essential to know how to perform calibration of inputs and sensors.
