I would qualify that as, "If you do your code carefully in 'c' - moving from one micro to another is a lot less painful" If you do your program :-) carefully in asm, the "pain" involved in moving from one micro to another is the about the same as if it would be in C (written with the same amount of care). Think about the steps needed to do that. The only step you spare using C is the "rough translation" from asm to asm, but that tends to be the easiest task around. The necessity to thoroughly understand both platforms, to rewrite the "hardware dependent" parts, to re-optimize the critical parts (and to study and understand the whereabouts of the application if it was not written originally by you)- these remain the same.

but the mere act of choosing 'C' as the language does not of itself guarantee portability! ... and the mere act of choosing asm as the language does not of itself mean problems with portability. This is absolutely the same flame as the "classic" C vs asm: while it is not completely true that asm gives you smaller and faster code, conversely it is not completely true that C is easier and results in shorter development time. Don't get me wrong. I don't advocate asm as the best and universal tool. Jan Waclawek PS. Sorry for the paraphrasing, it just came handy. |
