I'm trying to receive data from a piece of industrial test equipment and process it with an Arduino UNO.
The end goal is to receive two pieces of data (numbers between 0 and 5000; whole numbers and decimals) and display the difference in values on an LCD screen.
To start small, right now I'm just [u]trying to receive data from the tester and display it in the serial monitor[/u].
The serial settings for the tester are set to: BAUD RATE = 9600 DATA BITS = 7 STOP BITS = 1 PARTITY = NONE
I’m using a “Cutedigi” RS232 Shield (http://www.cutedigi.com/arduino-shields/rs232-shield-for-arduino.html) with a null cable connecting the shield and the tester.
I’ve used some sample code that I’ve found online, but I can’t get the test values to show up in the serial monitor. One piece of code just gave many lines of gibberish that I can't understand, but at least it was something.
Is there some simple code for testing this?
