#176359 - no reason in what you show Responding to: ???'s previous message |
the reason must be in what you do not show. Cut what you have down to a complete "T0 excersizer" and post the code.
BTW get rid of the interrupt disable and enables in the ISR, they are just fillers and have no meaning. Erik |

| Calculations for Timer T0 at 8KHz: have you tried 0xFF8D ??? | 01/01/70 00:00 | |
| correction | 01/01/70 00:00 | |
| Yeah - 0x8D | 01/01/70 00:00 | |
| Thanks for that typo, More for 8KHz with 50% duty cycle | 01/01/70 00:00 | |

| fine, but | 01/01/70 00:00 | |
| T0 overflows at 65535+1, don't overlook this | 01/01/70 00:00 | |
| right answer, wrong premise | 01/01/70 00:00 | |
| Exact calculations require semantics | 01/01/70 00:00 | |
| you are welcome to find out | 01/01/70 00:00 | |
Thanks for the correction... | 01/01/70 00:00 |
