#128120 - finally I found Responding to: ???'s previous message |
out that this is not working (my original posting)

Yes, 70% I'm doing ASM and not C, sorry again. |

| erm dunno but | 01/01/70 00:00 | |
| Errr | 01/01/70 00:00 | |
| Aside: XTAL | 01/01/70 00:00 | |
| no no | 01/01/70 00:00 | |
| Missing the point | 01/01/70 00:00 | |
| basic C | 01/01/70 00:00 | |
| preprocessor does not do it! | 01/01/70 00:00 | |
| Thanks Andy | 01/01/70 00:00 | |
| Why floating point? On an 8051? | 01/01/70 00:00 | |
| yeah | 01/01/70 00:00 | |
| preprocessor does not do it! | 01/01/70 00:00 | |
| sorry but its still not working | 01/01/70 00:00 | |
| expand and see | 01/01/70 00:00 | |
| Not quite... | 01/01/70 00:00 | |
| Do it by hand! | 01/01/70 00:00 | |
| ... or let the preprocessor do it for you | 01/01/70 00:00 | |
| to make things more clear | 01/01/70 00:00 | |
| Show your expansion! | 01/01/70 00:00 | |
| preprocessor output | 01/01/70 00:00 | |
| what you miss ... | 01/01/70 00:00 | |
| I don't understand your point, but... | 01/01/70 00:00 | |
| finally I found | 01/01/70 00:00 | |
| you are trying to be too good | 01/01/70 00:00 | |
| I'd guess.... | 01/01/70 00:00 | |
| wow | 01/01/70 00:00 | |
| I know that, but they are similar enough to .. | 01/01/70 00:00 | |
