#176376 - TL0 and TH0 Responding to: ???'s previous message |
I write :
TL0 = 115; TH0 = 0; but it don't work. I've tested : TL0 = 0x01; TH0 = 0xFD; it works. I can't understand how to determine TL0 and TH0 to have a freqency of 8kHz My micro runs at 11059200. It means that I've an impuls 921600 every second. what value have I to set in TL0 and TH0 ? or who to compute this values ? Thanks |

where is the EA initialize? | 01/01/70 00:00 | |

no reason in what you show | 01/01/70 00:00 | |

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 | |
Put the compiler to work... | 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 |
