#39879 - Also try 9600 + baud Responding to: ???'s previous message |
The 11.059 crystal is good for UART
and should give you 0% error rates at 9600 on up, at least with PICs and AVRs. I guess the 8051 can handle slower speeds. As you can see, for the AVR the error rate goes way above being usable at 2400, but over that it is 0% all the way. (>=2400 is too slow, the multiplier does not go past 0xFF) (the below UBRR calculations are for AVRs) Baud Rate UBRR %Error Actual Baud 2400 255 11.1 2700 4800 143 0.0 4800 9600 71 0.0 9600 14400 47 0.0 14400 19200 35 0.0 19200 28800 23 0.0 28800 38400 17 0.0 38400 57600 11 0.0 57600 76800 8 0.0 76800 115200 5 0.0 115200 |
