ARM has made their elegant 32-bit RISC processor core available for licencing to chip manufacturers, who have used it to produce a wide range of very cost effective microcontrollers, packed with lots of peripherals and generally requiring quite simple support circuitry to run. Easy to use, not demanding much space or power, affordable, and bursting with processing power and storage capacity, they seem set to become a popular device in many embedded applications. There's been a lot of hobbyist interest, too, since the devices look like a painless way to add intelligence to electronic devices....Go

This is a parallel port JTAG Debugger circuit for Philips LPC2xxx ARM microcontrollers. I haven't built it yet - maybe there are still some bugs. It is intended to be backwards software compatible with "wiggler" JTAG debuggers. The circuit was originally based on Leon Heller's "wiggler" clone schematic, then tweaked by suggestions from the LPC2000 Yahoo Group members....Go
