The Secret Book of FRC LabVIEW

[gnunes]

Greetings all-
Attached is a new edition of the book. It addresses some issues raised by readers, as noted below. (And thanks for the feedback! It is much appreciated.)

This error has been fixed, and the discussion of timing in Robot Main improved (I hope).

So, you select a group of items, press ctrl-u, and it cleans up only the highlighted code. Bam!

I never said they were less than helpful, only that the results were not to my taste. But I like the clean-up only the selection tip, and have added it.

BTW can u upload the labview file of the PID simulator? (for both victor 884 and jaguar)

PID control is very mathematical. There's no getting around it. But I did rather jump right into it, so I've added an introductory section that explains the basic idea. It is very difficult to explain, for example, integral control with just words, however. I'm afraid that younger students with limited math won't really be able to follow this chapter. But that will give you something to work towards for the following year!

As a matter of teaching philosophy, I don't want to upload the VIs. The only way to get good and fast at coding LabVIEW is to have lots of practice coding LabVIEW. Hence, no uploaded VIs...
