External Serial Monitor for arduino

Other Hardware Displays
1

Hey Guys,
I want to externally monitor the serial ports of arduino. Arduino we are used is communicating with matlab and the PC is busy with MatLab. We want to monitor the serial ports of this arduino without disturbing the PC to which the arduino is connected.

In simple language, I want to see which datas are being transmitted or recieved by the arduino using an external LCD screen.

How to do this???

Easiest way, grab a USB to serial adapter. Connect GND to GND and Arduino TX to adapter RX. Now open the serial monitor on the new COM-port.

Note, this way you only see what the Arduino sends to the PC. You could make a circuit to grab both PC->Arduino and Arduino->PC comminication but you would not know which is which. Again, if you want to also see what the PC is sending, grab a second USB to serial adapter. Connect GND to GND, Arduino RX (aka PC TX) to adapter RX. Now you can use a serial monitor on the third COM-port as well to see what the PC sends.

Yes, but that would be a complete project of it's own... I've seen some, but it ain't quick...

And . . . STOP CROSS-POSTING.

help me with the codes and connection of that?

This is one I found some time ago. Did not look into the details.

But the basics are pretty simple:

  1. Get a micro to interface with a screen of choice
  2. Get that same micro to read serial
  3. Glue that together.
