Thanks a lot for the link. What is the demo board are you using in the institute? The JTAG wiggler and the boards are not that expensive (but hard to be built by oneself because of the footprint) so that I may consider to buy one. Which board will you recommend? My initial target is quite modest, just to get familiar with the LPC2xxx chips and the assembler and C compiler. The IDE looks quite nice. Sorry but I think there are missing files in the ram-rom.zip (main.c, etc). It is a pity that the site is not in English.

IMHO the step above the PIC/AVR should not be the 30F or a high-end AVR but an ARM or another high-end processor (I am not familiar with others, but they probably exist). ... Check Olimex. The Philips ARMs have a build-in bootloader and can be programmed with a JTAG wiggler (also available from Olimex). The IDE we used in my classes can be found at http://et.fnt.hvu.nl/et/docenten/Bent/arm/ARMDevEnv.exe (GNU C, Assembler), the latest basic project files are at http://www.voti.nl/hvu/D3EEMS1/ram-rom.zip. For next school year I might integrate Java into the IDE.
