#178995 - Baud rate errors Responding to: ???'s previous message |
Raj Nambiar said:
when it comes to what makes it possible for the UART in PC to connect to bauds that deviate from the ideal value, and not for the UARTs in say a PIC or 8051, I don't have my basics right. Is the method different? No, it isn't. There is no particular reason, in general, why a PC should be more or less tolerant of erros than anything else. Of course, in a specific case, it might just happen that things conspire so that the PC just happens to work and the 8051 just happens not to... See: http://www.8052.com/forumchat/read/91002 Draw yourself some diagrams with the 16x baud rate clock and 3 sample points, and then try lining that up with some data patterns made with (slighly) incorrect bit timings...
