Hi, My sketch using the TIMEPLOT feature is now giving me a "Variable not defined error" when i try and compile the sketch but the same sketch compiled before and worked. Can someone help me figure out what is going on with the TIMEPLOT error and why it all of a sudden stopped working?

This is my Arduino code..

#include <MegunoLink.h>

Hi, seems like a clash with the time library.
Can you remove this library and confirm it fixes the problem:
Time-master at version 1.5 in folder: C:\Users\Greg\Documents\LTSketchbook\libraries\Time-master

I removed the "Time Master Library" and the undeclared variable error went away but i get other errors because i use the functions in the time library in my code.

Hi, I took a fresh install of version 2.0 of the arduino IDE. I installed the following libraries and it complies fine:
"SparkFun MS5803-14BA Pressure Sensor"
"Time by michael margolis"

and MegunoLink.

Is that a different time library? Will it work for your purpose?

Cheers
Phil

Good News! I did a new install of the Arduino IDE and i deleted my old library file and i got my sketch to compile ok. Before i reinstalled Arduino it used the old library folder and i had the same issue but starting a fresh library folder fixed the issue!

Thank you for the help!
