Subject: 'Free' ICD working


> I assembled the circuit, programmed the micro, and the ICD works

> A few notes on the current schematic, though:
> R21 should be 10K
> R22 should be 1K

> Everything else is according to the current ICD users guide on the

> I did not use the boost converter section, leaving RC2 unconnected and
