I wanted to build a ICD2 but the simple version cant work on 3.3V. So i went to design a 3.3V version without the logic gates. And with USB support because com ports are disappearing and needing external power.
What i did was use a bidirectional level shifter chip from maxim.Also a small change to the MCLR part of the circuit so it will pull up to targets supply and not 5V.
Anyone sees a reason why this wound not work?
