communicating with a raspberry pi !

Projects Programming

Deal all,
I am using arduino and raspberry pi to send information to each other via serial port. I have been successfully able to send information to the raspberry pi and even receive on the arduino.

But I got stuck when I needed to check and compare the values, since the raspberry pi sends the data once, I am trying to create a while loop which looks something like this:
while(Serial.available() < 0) { do nothing} // which keeps it busy until the raspberry pi finishes sending the information.

Then when I read the data it gets lost somehow.

Is there an alternative way to read the serial data and work with it.

You need a more robust system for receving your data. Look at the examples in serial input basics.
