Upgrade to ARC Pro
Harnessing the power of ARC Pro, your robot can be more than just a simple automated machine.

8 new commands are like 8 new tools, in the toolbox.....awesome! Rich and others are gonna flip when they see these..(its hard to type when I am flipping
) Thank You DJ!
Yep, I'd seen them before I went to bed last night but needed sleep so couldn't do any flipping
Now I just need to figure out what I can do with these commands... I have a few ideas
As always, thanks DJ.
These commands will be very useful for any new i2c devices that you'll be adding
Do I understand correctly that the GetBits function counts from LSB, not MSB? In the example provided : $x = SetBits(1, 0, 0, 0, 1, 0, 0, 1) --> MSB (0) to LSB (7) GetBit($x, 3)) should return 0 if counting from MSB...
There's help on the right of the script editor
so unless you use EZ-Script to a high extent this update isn't really important.
I would update - it won't hurt
