Greetings,
Interesting stuff! Thanos, you go boy!

...or... Yesterday??????

Yeah, exactly.

You *..whether you succeed or not doesn't matter (to me). Or when. You are a very generous person. Thanks for all you've done, and are still continuing to do. You're a good role model here.

There....did I embarrass you enough yet?

Hey Tronic,

I just bought two of the Open107 dev boards and will be glad to work with you on this project with you (where/when possible).

Also, check out this thread and comment on how you think it may affect this project.

Hi Tronic,
what is your opinion regarding the usefullness of this board (or similar) for our motion control needs ?
Do you consider it a longer term study for the next generation of simulators, rather than something that could be used in the near future? I ask as I am proposing a new sim build and the controller is my main concern, and there is no point in cutting metal before I have confidence in the electronics, which I insist on being able to set up and fix myself.

Would an internet survey of other DIY's CNC hobby machining motion control, or robotics, assist in your efforts to develop the Cortex M for our particular needs ? Can a solution be partially purchased to accelerate the development duration? I have a particular interest in a controller for a six actuator configuration in the future.

Thanks for your efforts on our behalf.

Watch the arduino thread. viewtopic.php?f=39&t=695 , from what I understand , either this board or a bigger ard board can control 6 DOF. And you do not need a $2500 program to run it.

Yes, an arduino could drive 6 motors, but with only 8-bit resolution. Also the 57.6k baud speed is just enough for these 8-bit data. Really good for small DC motors or scale model.

A better approach from my side is to make the whole thing almost real time. Fast serial (500kbps), fast math (1000-3000 times per second), fast position control (1000 times per second). And no, you CANNOT do that with the standard arduino libraries. I had to hack my way through to make my arduino based digital dashboard stable enough for these speeds. I just prefer to use my own mix of basic/ASM code to be able to push the hardware to its true limits.

With the open107 project we can have except the above speeds for communication and control outputs, the luxury of really nice precision for the positioning math. Heck I could even include in the code coordinated motion of the motors for a 3DOF, 4DOF or the real complex math for 6DOF Stuart Platform.

I can't promise when, but it would be really interesting to embed everything in the very near future.

@Motiondave
Stop saying it needs $2500 software... Atollic studio has lite version that can cover enough code size for a motion controller with LCD menu and even realtime graphs of the PID math. And there are other free eclipse compilers around as well (if you can handle Ubuntu).

ok sorry about the $2500, I will shut up.

Hi, Thanos.

In that post http://x-sim.de/forum/viewtopic.php?f=39&t=237&start=140 you say:

I ported the code for my AMC644USB (6DOF) into a Arduino Mega two days ago. I got it running up to 500kbps Baud with x-sim

But now you say:

Yes, an arduino could drive 6 motors, but with only 8-bit resolution. Also the 57.6k baud speed is just enough for these 8-bit data. Really good for small DC motors or scale model.

We can create 6-dof firmware with 10-bit resolution for each axis using ArduinoMega hardware platform. And no problem to make communication on baud 250 and 500 kbaud. Yes, we can't use scetches for this, but we can use basic, C, assembler.

I also think that using the Arduino sketches we can not create an effective code required for the x-sim. But there is a way to allow use of all the resources of this simple hardware platform. You can write firmware on any progamm language and upload to Arduino compiled HEX file. And it works great.

Many thanks for your work.

Ale
