---

This example is a demo project to calculate divide with DSP
> Support `signed 32-bits` input

+ the remainder
    > + In math theory, the remainder should be `>= 0`
    > + In computer implementation, the remainder may be sign

## Log

Use serial port with baudrate 115200, 8bit, no parity check.
