#147969 - 11.5198 MHz! Responding to: ???'s previous message |
Richard Erlacher said: Indeed it is the good solution,But is there 11.5198 MHz in electronics shop,Or i must to adjust an external VCO or timer to generate such clock frequency?
It depends somewhat on the data format that you intend to use. If you use a short word, i.e. 7 bits + 1 start and 1 stop, you can probably "get by" using the same frequency for both.
If you use an oscillator of 11.5198 MHz, rather than 11.0592, and use the same setup for both baud rates. That allows you to "set it and forget it". |
