#128070 - SDCC how to |
convert an integer value to a char using the preprocessor.
I've followed your given ASM example inside the tutorial to write some similiar code in C. #define XTAL 22118400 #define MACHINE_CYCLE 12 #define TMR_OV_SEC XTAL/MACHINE_CYCLE #define F40TH_OF_SECOND TMR_OV_SEC * 0.025 #define TIME_SCND 40 #define CLOCK_RELOAD 65536-F40TH_OF_SECOND+14 CLOCK_RELOAD is an integer value but to use the result to reload TH0, TL0 I have to split that into 2 char variables. Does anybody know how to do this in SDCC ? For the moment I'm using a workaround but this takes some resources in my C code. I think there must be a way to solve that inside the preprocessor. |

| erm dunno but | 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 | |
