The programmers have their own preferences on programming languages. Me too, personally I enjoy C, Perl and PHP because of my working experience in electronics engineering and web programming. Here I will summarize the language capabilities for hardware programming. Different programming languages are designed for specific purposes.

OpenAVL is an AVL (Automatic Vehicle Location)open source project.The OpenAVL is one of my on-going open source projects. This project is written in ANSI C. The prototype board is made up of a low cost GSM M2M module (MC39i) from Siemens/Cinterion, a GPS OEM module from Leadtek and an AVR microcontroller (ATmega128L) from Atmel. It will be ported to Emcelettronica's IperSMS board, which has a PIC18 and a Telit M2M module. I will share my development experiences in these blogs.

Infrared communication is a low-cost method of wireless, point-to-point communication between two devices. Even more and more communication methods including USB, Bluetooth, and Zigbee are implemented on the microcontrollers.

Cockroaches or Blackbeetles are nasty pests living in our house, carrying germs to our food and drink. People have tried all kinds of ways to get rid of these annoying neighbors, poison, trap, even laser.

I introduced Loongson 2E/2F general purpose RISC CPU in my blog. Loongson is based upon MIPS III ISA, developed by ICT and manufactured by ST microelectronics.

Do you realize that Freescale's JM Badge board can be designed into a seismometer? The board is presented in FTF2008, distributed for free as name badge and starter kit for JM badge contest 2008.

Cortex-M1 offers highly portable microcontroller design over many FPGA devices, with reusable tools and code base. It offers compatibility and ecosystem across FPGA, ASIC/ASSP/MCU.

USB was a big challenge for developers. Since the USB development demands deep knowhow in host drivers for operation systems, device drivers in the embedded system, and application software development as well as debug between host and device.

The creation and consumption of cool gadgets has become a way of life for many designers, engineers, and billions of consumers. These gadgets, whether for music, video, Web navigation, games, or communications, keep getting ever more sophisticated, smarter and smaller.

As I mentioned in another article, ARM Cortex-M3 is not compatible with ARM7TDMI in interrupt, ISA, bus structure and JTAG protocol (SWD). You have to upgrade ARM7TDMI tools to support Cortex-M3 microcontrollers. After a small research, I summarize following tool related information for your reference.
