The LPC1769 LPCXpresso board with NXP's ARM Cortex-M3 microcontroller is part of NXP's low-cost development toolchain for LPC families. It has been jointly developed by Embedded Artists, Code Red, and NXP. It is an end-to-end solution for creating applications all the way from evaluation through to production. Here are some of the highlights:
• The target board comes with an integrated JTAG Debugger. No need for a separate emulator!
• A free Eclipse-based IDE and compiler is included (128K download limit)
• Easy upgrade options to full-blown suites (from Code Red) and hardware kits (from Embedded Artists).
