Question

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 1

"115200 and 460800" is the correct approach.

Step-by-step 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:

=
`(100* 8)/(10* 10^(-3))`

=
`(800)/(0.01)`

=
`80000`

• 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.
