#187832 - "UART value" crystal Responding to: ???'s previous message |

The crystal frequency must (sic?), if you use serial comm's be a "UART value" I don't think it's an absolute "must" - but using a "UART value" crystal will certainly give you the best chance of being able to hit the most standard baud rates in the most situations. http://www.keil.com/c51/baudrate.asp |
