21 | This protocol decoder tries to guess the bitrate / baudrate of the | |
22 | communication on the specified channel. Typically this will be used to | |
23 | guess / detect the baudrate used in a UART communication snippet, but it | |
24 | could also be used to guess bitrates of certain other protocols or buses. | |
25 | ||
26 | It should be noted that this is nothing more than a simple guess / heuristic, | |
27 | and that there are various cases in practice where the detection of the | |
28 | bitrate or baudrate will not necessarily have the expected result. | |
29 | ||
30 | The precision of the estimated bitrate / baudrate will also depend on the | |
31 | samplerate used to sample the respective channel. For good results it is | |
32 | recommended to use a logic analyzer samplerate that is much higher than | |
33 | the expected bitrate/baudrate that might be used on the channel. | |
