Explanation.

Answered - If i were to tweak the distance out a bit to give me the degrees, could that be used instead of the ticks?

Answered - Is the number of the ticks the numeric values in true and false structure connected to the PIDs?

Answered - Could i use this to rotate a motor a certain degrees?

Answered - Can anyone explain to me to whats going on here. I do understand most of it but when it says "Arm Binary" i am confused. I do know its a global variable. Is it the current position of the arm? Any help is greatly appreciated.

It gets a bit complicated, but it looks like they're using different combinations of buttons to determine what the height of the arm should be. From the looks of it, Arm Binary is just a conversion of binary values into numeric values which is then linked to a global variable for some reason. I would guess it was to change something on the driver station.

Okay so its really not needed cause im not going to be placing anything on my driver station. Could i use this to rotate a motor a certain degrees?

[juchong]

Sure. What you're interested in is the Arm Raise portion of the code. This section looks at an encoder and counts how many "ticks" (lines on the encoder wheel) have passed. Depending on what the constants in the case structure are is the amount of ticks that it should count. Once it knows how many, it should then keep moving the motor until that many have been counted.

Okay cool. Is the number of the ticks the numeric values in true and false structure connected to the PIDs?

[juchong]

I believe so. I'm not sure what that PID block's inputs are since I don't have LabVIEW open right now, but it makes sense.

I do appreciate you helping me out. I have one more question if you don't mind. If i were to tweak the distance out a bit to give me the degrees, would i be able to use that instead of the ticks?

[juchong]

You could, but you would have to find some sort of "ticks vs degrees" relationship via experimentation. Maybe have the robot move 20 ticks and check how many degrees have been moved on your motor.

okay thank you. I think this example would help out a lot of teams. Thank you very much for your help. If i have anymore questions, would you mind if i messaged you about it?

[juchong]

Don't mind at all, although if it's something that other teams should know feel free to start a topic and message me the link, that way more people benefit!

Alright sounds good. I just been reading other topics in the past couple days. Most of them were asking how to have a motor controlled with a push of a button using an encoder.
