NEW PRODUCT – MicroBuilder LPC1343 (ARM Cortex M3) – The LPC1343 is a low-power, 32-bit ARM Cortex-M3 microprocessor designed specifically for embedded devices. This is a fully assembled version of the LPC1343 Reference Design from talented Parisian designer, Microbuilder. No soldering required (female header pins are pre-soldered onto the board), this devboard is ready to go out of the box.
Please note that while there are some great introductory getting-started tutorials for this board, its best used by those with microcontroller experience. If you’ve played with AVR or PICs and are intrigued by the low cost and ultra fast 32-bit ARM Cortex M3 series, this is the dev board to get! If you’re just getting started with microcontrollers and electronics you should check out the Arduino which is very beginner-friendly!
In addition to publishing the schematics and layout files, MicroBuilder has written a full software library for the LPC1300 family. This allows you to quickly get started with all on-board peripherals, so you can focus on your own application functionality. The software library includes complete GCC-based startup code and details on setting up an ARM development environment using open source tools. Along with a standard Makefile, project files for the open-source CodeLite C/C++ IDE and the commercial GCC-based Crossworks for ARM are provided.
Within minutes, you’ll be using the USB interface for printf() debugging, reading from the analog inputs using analogRead(), tweaking pins without having to look up registers, etc. and best of all no ARM or JTAG programmer is required! The chip comes with a built in USB bootloader that appears as a very small disk drive. To reprogram, simply press the Bootload button and drag your new firmware file into the USB drive that appears. Then press Reset and your code is running. Is that cool or what?
