There is an inertial measurement unit (IMU) measurement sensor that needs to update 98 bytes data (with extra 2 label bytes) every 10 ms (100Hz), what is the minimum requirement of the baud rate

Answer:

"115200 and 460800" is the correct approach.

Explanation:

Total Bytes = 98 Data Bytes + 2 extra label bytes for every 10ms

                   = 100 bytes (every 10m)

Rate of data for every second will be:

= [tex]\frac{100\times 8}{10\times 10^{-3}}[/tex]

= [tex]\frac{800}{0.01}[/tex]

= [tex]80000[/tex]

  • The minimum baud rate required seems to be 80000.  
  • It is appropriate to be anything higher than 80000.  

Consequently, the 115200 as well as 460800 baud rates seems to be appropriate.
