Thanks all of you for the answer. So generally speaking better to use ICSP and my shaking hands to put it into its place :-) I have to rethink the whole and have to go back to the library :-) Anyway, the matter of fact the 10F200 is more than enough for this module (currently using only the half of the program memory space of it) and I just thought I could make just a bit bigger PCB so that the few resistors and capacitors around it fits perfectly but no more. Sorry for the stupidity of me but I am coming from the computer programmer field -- ok, as a low level programmer but it is still... Thanks very much again!
