I have been using ICE200 in two projects and was quite satisfied. Its good value for money.
BUT: I used an AT90S2313 in SOIC package in my first project. To use ICE200 in my target system I bought an adapter from Emulation Technology for $80. Expensive! In my second project I used a QFP AT90LS8535. Emulation Technology charged me the senseless amount of $265! Unbelievable!
Does anyone know a good source for reasonable priced surface mount emulator adapters for the AVR.
