  • Understanding why framing error (EUSART)

    2015-3-8u2002·u2002A 'framing error' means that the USART saw a low when it was expecting a high (in the middle of the STOP bit pulse). This means one of: [1] Your baud rate at sender and receiver are very different, so the receiver (i.e. the PIC) is sampling each bit earlier and earlier, so it sometimes sees the end of the 8th bit instead of the middle of the ...

Now that we have seen how to transmit a sequence of bits over a point-to-point link—from adaptor to adaptor—let's consider the scenario in Figure 26.Recall from Chapter 1 that we are focusing on packet-switched networks, which means that blocks of data (called frames at this level), not bit streams, are exchanged between nodes. It is the network adaptor that enables the ...

    With the 'good' interface, the stop bit has full length, so the busy bit goes 0 after the stop bit has been properly detected and before the start bit starts. You can do some sort of auto-baudrate detection: If you get a framing error, you can alter the baudrate settings until you don't get one anymore.
