Tronic's proportional servo motor control with basic stamp

[tronicgr]

I just forgot to delete these vias when redesigned... They have no use...

The delay on LFS was because of the smoothing of the profiler that existed even if you pilled all the way down the bar setting to "weak". Sirnoname sended me a new version of profiler that had another "tick" on the bar that totaly disabled the delay of the smoothness.

Now it runs really fast and the responce time was fallen below 20 ms. In the new version you can actually see the spikes on crashing into a wall. Now It moves the simulator even when you shifting gears!!! Cool!!

I hope he puts it on the next release to see it for yourself.


Today I bought a car battery to power the motors (TUDOR model TC10) with capacity of 100AH!!! This beast will be enouph to move my simulator for atleast straight 4 hours with no intermision. The salesman was so impressed by my construction that he gave me the battery for 60 euro cheaper (I paid only 100euro)!! I also bought a 10amp car battery charger to charge it when not using it...
So be patient to connect the battery for the new videos...

I might try and design such a board with a socket to accept the BS2 chip on it. And maybe with an extra "programming serial port" to able to update the firmeware on it without having to remove the BS2 chip.

That would be really great!!!!
I would really appreciate such a board, and would like to replicate it, as well!

I know that the BS2 Controller Boards are affordable. But we like the DIY way. And everyone could decide for himself, if he would like to buy a ready BS or if he rather would like to build a PCB by himself.

BTW, with how many wires are your motors connected to the controller. Two, or more?

Yeah, good work.

How about beta testing more axis ? Perhaps on twice serial outputs ?

I'll design such a board with a standard BS2 chip socket for all to have it here. Just be patience because of lots of things I'm involving with right now.

One of the things I'm making is a new interface based on a ATmega8535 that will receive the data on 56K and run multiple checks on the position in each data update interval. I'll still use HB-25 motor controllers to drive the motors...

The motors are conneected with just two wires (Positive,Ground) to the HB-25 motor controllers.

How can I define more axes on the USO? It seems to have available only x,y. I know I can use the second serial port in there but what about the more axes? The profiler doesn't seem to give z,yaw options.

And when I tried to run more than once the profiler it gave me back error about opening the serial port. I guess the second profiler tries to access the already opened serial port of the fisrt profiler.

Any suggestions? A patch maybe that defines more axis than x,y to the desired force?

In the registry you have to generate the key "DualRun" in

HKEY_LOCAL_MACHINE\Software\X-Sim\Force-Sender and set it on "1".

Than you can start the Force-Sender twice! If you use a second control PC you can send the complete datapackages to both of them.

So you can control 4 Achses. Ok, it´s a workaround, but it should work.

Yes, I already tried this and had two force-senders. But the problem was on the profiler!!!

I couldn't define more axis in the serial string: B~x~P~y~
There are only x,y available.

And when I tried to open a second profiler to run a second serial interface it won't open for second time and gave me the message: Error opening socket (or something).

The way I see it, changes in the profiler are needed to be able to assign the extra available forces to more axis. i.e z-heave, z-rotate etc...

And I prefer to use only one computer to elliminate as possible all the delay issues of the network communication...

I talked about profiler 2.0

Well, here you go. I made a small board that hosts the Basic Stamp2 chip and sits on top of the interface connections board. It has programming serial port and It also has power source regulator that also powers the interface connections board directly.

I also fixed some minor design issues of the bigger board and alligned it to be ready to host on it the smaller board with the BS2 chip.

That was fast

Nice, I see support for 4 Servo Motors, adding the heave and yaw axes.
