What is embedded system?

An embedded system is a computer system designed for specific control functions within a larger system, often with real-time computing constraints. It is embedded as part of a complete device often including hardware and mechanical parts. By contrast, a general-purpose computer, such as a personal computer (PC), is designed to …

Build Your Own ARM Cross Compiler Toolchain

Build Your Own ARM Cross Compiler Toolchain GNUARM is a set of open source GNU compiler for ARM microcontroller. The toolchain consists of the GNU binutils, GCC compiler set, Newlib and Insight, the graphical user interface to GNU debugger for Windows and Linux. This article will guide the building process …

Learn Embedded Linux with ARMulator

Learn Embedded Linux with ARMulator uClinux is an excellent way to study the embedded operating systems for an engineer, student, hobbyist, Linux-enthusiast. I am interested in Embedded Linux for ARM microcontroller. Before buying a new mcu evaluation board, there is a smart way to study the Embedded Linux. That is …

Control a robot with a watch

Control a robot with a watch Some six months ago Texas Instruments announced the Evalbot, a development platform for their Stellaris ARM Cortex-M3 microcontrollers in the shape of a little robot. It took me a while to get hold of one, but now I have one driving happily around in …

CodeLite GDB for ARM

CodeLite & GDB for ARM Just after finishing the Elektor article about how to debug the Sceptre (or any other microcontroller that can be debugged over JTAG) using OpenOCD and GDB, I discovered another free IDE that seemed to be good for embedded development: CodeLite. It seemed to have everything …

Break the 816bit habit

Break the 8/16-bit habit Most people, including me, like to get stuff for free. Electronic component manufacturers know this and often they offer free samples in the hope that their parts get designed in. Microcontroller manufacturers have started doing design contests and other campaigns to get new users for their …
