In another form:
a) are you familiar with the '51
b) are you familiar with C

Erik,

Well I think both a & b I not familiar with, but ...

a)I familiar(have done 15K cmd line of asm prog) with 6811 and PIC (assembly) so I think to move for '51 only matters of different architecture and command set.. others r same.... am I right?

b)about C, I've learn C++ 2 years ago and not practicing it. As far as I know .. to programme it, has to use ANSI C


So, if I can have a complete(can be compile without error) simple program written in C that operate with AT89C55WD plus the curciut .. It will help me a lots

cos so far I try to compile a downloaded programme sample... it give an error
