I know assembly, but not for 8051, I worked with assembly for MC 68k , I even wrote an assembler and simulator for it in a university subject, so i know the basics but i dont know the mnemonics for 8051 and I dont think that will be a problem, but I was asking about what would be more efficient to work with assebly or C ?, and i think now that C would be, but i still had to learn 8051 assembly
