hi,
Has anyony built a EasyICEarm7 debugger for the Embest IDE 
sucessfully ???
I've been struggling to do so ..... The PC does no seem to recognise 
that there is something at the other end. 
Though the 244 ic seems to be able to give out the 3v signal, does the 
PC recognise a 3V signal ?? 
Has anyone sucessfully built one for the Embest ide??
Regards
Sameer
