Hi All,

Usually I use 12f863 in my projects but can't get them anywhere. I managed to get some 12LF1840 pics and find when I try to program them all 5 come up with the error of 'Target device does not match'.

I am using Melabs U2 programmer with ver 4.67 software.
Microcode Studio ver.
and PBP

Have tried with in-circuit programming and with 8pin adapter. Both give the same error.
Programmer works with a 18F2525 so think hardware is OK?

Any help or tips welcome as tearing hair out! (what there is of it).

Many thanks
