Let's Discuss (Senior Projects/Everythings) in our Forums

Working on Microcontrollers is needed some practical experiences. Due to this reason, I started the Microcontroller Programming Forums for community discussion. The aim is to create an online discussion board there the members can helps each other. Sharing an experience is expectation for our Forums. Whoever you are i.e. Engineer, Scientist, Student, Hobbyist, alls are welcome to our forum:

For a student who is working on senior project related to MCUs, it is a great chance to find an expert you can consult online.

Why don't you joint us. Please become our member.

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 of GNUARM toolchain only for Linux users. For Windows users, there have the installer executable EXE files already. www.scienceprog.com has a tutorial on setting up this tool on Windows environment.

8051 mcu, von Neumann vs Harvard Architectures

We can classify computer architectures into two categories:

von Neumann architecture: computers has a single, common memory space in which both program instructions and data are stored. There is a single internal data bus that fetches both instructions and data. They can not be performed at
the same time

Harvard architecture: computers have separate memory areas for program instructions and data. There are two or more internal data buses, which allow simultaneous access to both instructions and data. The CPU fetches program instructions on the program memory bus.

iF-DEV Free Tools for ARM7/9/XScale

You can get started developing on an ARM for only $99 with dev. kit from iSystem AG. iF-DEV is a complete development tool solution for ARM7, ARM9 and XScale (see Fig. below). The system includes includes everything you need to get started. The small target board contains an ARM-based NXP LPC2138 microcontroller along with a USB-based JTAG debugger. Power to the target is provided by the JTAG’s USB interface.
