WebFeb 16, 2024 · The baud rate is 150 bauds/s if the bit rate is 1,200 bps and the number of bits is 8. The formula to calculate the baud rate from the bit rate is: Baud rate = Bit rate / Number of bits in a baud. So, you divide the bit rate, which means the number of bits per second, by the total number of bits in a baud, and the result is the baud rate in bauds … WebAug 13, 2024 · Baud rate chain on the micro. Most micros allow you to divide their internal clock by some integer, and the result will be 16x the baud rate. If you had a micro running at 30 MHz, for example, then the fastest baud rate would probably be 1.875 MBaud. Some micros have a "high speed" mode where a lower multiple than 16 is used.
