Hello Mahmood,

My congratulations to you; you seem to have done quite a job!

I think the problem with us 'old hands' is that most, if not all, of us started out programming the 8051 in assembly and moved on to C (much) later. This has left us with a slightly warped mind ;o). Without 'C' we would still be using obol, Pasal or Basi. But note that there is no C in assembly .... :o)

Seriously; I myself just find it easier to do some things in ASM and others in C. And optimalisation, of course, is not a must. If the requirements can be met with C code alone, that's great! If I do need to optimise my code, however, assembly is my first choice. One recent device I designed had really tight timing requirements and I ended up with almost exactly 1:1 C to ASM code. The device I made before that had about 97% C code.

Again: congratulations (what do you mean, "not a pro"? Hah! :o) ) and may your planes fly well.

Regards,
Rob.
