This is my code. I am using a SHT31 sensor to send temperature and humidity from Arduino to LabView after receiving a character specified.

I am using also a heating resistors activated by a random number in the LabView interface.

Describe exactly what isnt working and what you want to achieve with interrupts.

You can pass a second argument to specify how many decimal places you.

This whole process is done by a program arduino and labview will be its interfacela communication between the two is made by sending and reception of the alphabet to know the step to do.

Also, describe if possible the communication protocol, and tell us whether its possible to change it.

I want to read a string that comes from the labview, and when I click the button (for example ON) he makes a serial print with values.

There is nothing in the ON or OFF packet that tells that the end of the packet has arrived.

When it receives a string (ON) it sends the Serial.print a value.

When he passed the string (OFF) it stops sending values Serial.print and is waiting for a new string (ON).

Code: Select char msg10; byte index 0; void loop() if(Serial.available() 0) char letter Serial.read(); if(letter ) Compare msg to ON.

Code: Select zoomkat 8-6-10 serial IO string test type a string in serial monitor.

Code: Select if(Serial.available() 0) string; I will use LO as your serial send.

The first time through the loop(), there will be an L in the buffer, which does not match anything.

The second time through loop(), it clears L from string, and it will receive an O in the buffer, which does not match anything either.

The serial monitor included with the IDE does not send a crlf by default.

Part of that process, of course, is defining what the problem is.
