btw, are the PID loops running on the NXT or on the PC?

[Fatzwonga]

now there are running on the NXT.. and it works fine.. but i have also tried to run the PID loops on the PC , just you can see on the other video.. it works also

[pranavtrehun007]

nice video and good use of the PID toolkit. How many PID loops do u run in a second?

I also wanted to use the PID toolkit to control a differential dive with two 600 count encoders. But i was worried that bandwidth between the PC and the NXT might be an issue.

any help plz?

thanx... In this Video the timing is configured , that every 30 ms the PID Loop is running.. I have test a lot but the result with 30 ms was a good solution..

I think the problem is also the usb device.. seriel transfer.. I saw that when i implement the pid direct on the nxt.. the whole system works much better

Nicely done. Nice example of what you can do with the NXT and the LabVIEW software.

Thanx... Yeah it just looks like a toy, but it was hard work to do this.

Anyway i think it was a real cool project..
