How to use this tool

  1. Enter the labeled inputs in the indicated units.
  2. Calculate and compare every output against the stated model assumptions.

Try this example

{
  "baud": 115200,
  "data": 8,
  "parity": 0,
  "stop": 1,
  "characters": 1000
}

Accuracy and scope

One start bit, continuous back-to-back frames; hardware may not support every listed format. Simplified analytical model; not a design recommendation or safety certification.
