Hello everyone,
I have a little issue which i cannot solve on my own.
I'm currently working on an I2C-communication between two arduinos (1Mega, 1 Uno).
If I print the sent values from the slave, I can see the correct data in the Serial print. (see code below).
The displayed value will then correctly be returned (print of returned value in other function).
HOWEVER:
When i delete the Serial print, which I marked with the comment, the function will return 255.
How can a serial print influence the actual data of my variables??
The content of the print message does not even matter. Serial.println("This sucks");has the same effect....
Any ideas?
Thanks in advance and best regards,
BoredEngineer
[...] //some other stuff
delay(1000); //waiting for an I2C message to be recieved
Serial.println(ii2c_sent_data_value); //THIS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
if(ii2c_sent_data_type != 0){
if(ii2c_sent_data_type == idata_type && ii2c_sent_plant_id == igoal_plant_id){
return ii2c_sent_data_value;
}
}
return 255;
