Adding two floating point numbers, perhaps, or calculate a sin and throw away the result? If you just throw away the result, the compiler may still realise that the code has no effect (other than to consume time) and optimise it out! |

| akkkk! stupid compilers, something to watch | 01/01/70 00:00 | |
| ehm, isn't it the user? | 01/01/70 00:00 | |
| Well it might be phooey;- but its pretty common | 01/01/70 00:00 | |
| have you considered using a timer, perhaps... :-) | 01/01/70 00:00 | |
| yep but... | 01/01/70 00:00 | |
| Sorry - not this time, Jez | 01/01/70 00:00 | |

| Maybe not... | 01/01/70 00:00 | |
| Beware. | 01/01/70 00:00 | |
| Well, any compiler with half a brain does that. | 01/01/70 00:00 | |
| volatile | 01/01/70 00:00 | |
| use util/delay.h and read the lib documents | 01/01/70 00:00 | |
| optimization = lost control | 01/01/70 00:00 | |
| well that is the first mistake | 01/01/70 00:00 | |
| First mistake is using a HLL | 01/01/70 00:00 | |
| Optimise & kill code | 01/01/70 00:00 | |
| optimizers and NASA | 01/01/70 00:00 | |
| There are many levels in Keil | 01/01/70 00:00 | |
not always a good idea | 01/01/70 00:00 |
