This sort of behaviour can easily trap the inexperienced embedded C programmer which is why I prefer to code such operations in assembler. Andy Neil said:
And assembly has no traps for the unwary, inexperienced programmer, of course...?! ;-)
PS Actually, this sort of thing can (and does!) trap any inexperienced and/or unwary 'C' programmer - it is not limited to embedded 'C'! We shall now pause for a moment, so that Steve can preach the Pascal gospel... As I said elsewhere I have no intention of starting a language war which is why I have tried to make clear I am speaking only for myself by using phrases like IMHO and 'I prefer'. No matter what language or hardware you use, there are plenty of traps in embedded systems for both the unwary and experienced alike. I think this forum does an excellent job of providing a range of solutions to them. Ian |
