Re: connection twe micro without serial port
As u r saying , their is a high possibility of data being lost.
Also u want to communicate 3 boards on i2c, their is also a possibility of data collision & system might get hanged.
You can do the following:
1) First of all use timeout method so that ur system will not be hanged in any case.
2) Divide the time into 3 (no of slaves to be communicated ) slots & send the data into respective slots only.
1) First store the data in ur slaves in a temp buffer along with the packet no.( here packet no is uesd as identifier) & send it to processor & do the same thing at receiving end...
Hope this will help u.
