Finally Got Arduino to Talk To Linux

FINALLY, I been working on this for a while.

I been trying to get Linux to talk to arduino via serial port.

Basically the read is what I am trying to do.

The huge breakthrough was finding a someone that did the source code in C:

Found it here

http://todbot.com/blog/2013/04/29/arduino-serial-updated/

You can download the source with git using the following command

git clone https://github.com/todbot/arduino-serial/

Then go into arduino-serial and run make

Then you got arduino-serial to play with

Here is how I used it in a bash script

#!/bin/bash
COUNTER=1
while [ $COUNTER -eq 1 ]; do
 SERIALCOMMAND=`/home/larry/bin/arduino-serial -b 115200 -p /dev/ttyUSB0 -r | dos2unix | grep "read string" | cut -d\: -f2`
 echo "$SERIALCOMMAND"
 if [ "$SERIALCOMMAND" == "TV" ]; then
 COUNTER=0
 fi
 echo $COUNTER
done

Note the dos2unix command.  It was the cause of major frustration for my script cause of the hidden strings.

Its all good though, it works, now I can run read values into bash on my Linux box.

Triumph

Earned right to be lazy doing pushups and situps then bed.
