Detailed Description

Main State Machine.

---

Function Documentation

int main

(

void

)

State controls to main program flow

initialize HW ports for input and output

Todo:

Configure counter so, that timeout is 1 second

Todo:

Change the counter to count every 100th message

Todo:

This case is just for testing. To be modified to Report Slave ID

2 is Place of datacount value in the ModBus Response Message

Here is the call graph for this function:
