Hello,
Me again…I was using NetBeans and this file: https://github.com/digidotcom/XBeeJavaLibrary/releases.
I am also using the THT Grove Development Boards. I have an i2c attached (barometer) via Grove Connection. I am trying to get NetBeans to read that software but I am coming up empty.
I tried java -version on Windows but there was no input relating to 32 or 64 bit. So, I tried both.
I also tried multiple paths starting with C:. What would you do? Please send guidance and/or feedback.
Seth
P.S. If you are interested, please view the error/output:
