4Dof-Controller code for arduino mega for AASD-15A and similar driver

For the DIY heads, the adaptation is ready https://github.com/ehmotion/eh-mfc tested with native telemetry on PC and PS4/PS5 as well as 'extrapolated telemetry' from the wheel/console controller data.

There is also a v2 for the Arduino controller which uses preset stroke length, check the details https://github.com/ehmotion/eh-msc-4dof

@cubexxx I am adapting your code to my stepper motors. I need 48800 pulses from low to high.
Can you confirm those parameters will work :
const unsigned int minPos = 0;
const unsigned int centerPos = 22400;
const unsigned int maxPos = 48800;

I tried your code with something as close as possible from your settings, but the actuator reacts with something like a 60 seconds delay...

Hello everyone

Being totally new to all the Arduino and motion simulator fields, I come to you for a few questions. I want to fly a 90St with the AASD 15a controller. The ram will have Surge use.

First question which may seem silly but why not use Simfeedback to drive an Arduino Leonardo as specified in the Sfx manufacturing instructions? Because it looks like an easy solution to implement. (but if you do your own code I guess there are advantages)

Second question, will your code be functional to be used for a surge?

Thank you

The arduino code used for Simfeedback is not open source and only works together with the simfeedback windows app, but this is quite restricted in comparision with e.g. FlyPT mover. Also I think my code is better because it generates better timed pulses leading to smoother motion. The code can be used for any kind of motion (e.g. surge), it's a general 4-channel pulse generator, the 4 channels are independent of each other

Your screenshot is a little bit low-res, I can see the "interval loops" beeing 0.5 ms which seems very low, that is 2kHz, why so fast? That may be too fast for the baud rate, you may have to adapt the code for that. I never used less than 2ms, not much to be gained by going lower as the servos don't react that fast anyway

ok that's what i thought about Simfeedback. I saw that you were not using a mechanical limit switch because you have a vertical use of the cylinder, so your zero point is always good. On the other hand for the surge, to avoid moving the chassis backwards to have a zero point, will it be possible to have an automatic calibration when the system starts? (with limit switch)
And one last question which is more of a service if I can afford to ask you. Would it be possible to have your code modified to just operate 1 cylinder (with limit switch if that and possible) because I am afraid to modify your code because I think I would do more nonsense than good. And with just the program for 1 cylinder it will be easier for me to understand how it works.

Thank you very much for helping me

I need a little help i made a 3 dof and i want to use 1 arduino per servo to make it move smoothly I used servoControllerContinuousRotation16bitOneChannel code. it works but not well.
when i start it up it runs too far.
I have an 80 ratio reducer with a 80pcs m02430 servo.

- Where can i adjust it to make the arm go from below 0 degrees off to 90 degrees at start up?
- is servoControllerContinuousRotation16bitOneChannel the right code?

Can you share your settings···

This is the wrong code for your needs. This code is for a continuous rotation axis like continuous yaw.

For a 3 dof rig use the servo controller ino file. This code can do 4 axis motion, just send 3 axis data and it will work great. It will be smooth, cubexxx did a excellent job using timers etc.

Thanks i'll give it a try. Here my settings .

Sir, can you tell me how to set it up? Flypt Filter Research

Hello!
Long story short I have a 90 ST motor and the AASD controller. I have built all the hardware for the belt, and now I need to connect the AASD controller to a board that can "talk" with my PC.

I have found 2 SW that could "control" the belt, one is FlyPt and the other is simtools, SRS does not work because I can't limit the "travel" under acceleration, it will get "lose"

I have read about 2 options, but I'm not sure if it is what I need, and here comes where I ask for your help. I could buy a Thanos board (a bit overkill for only an active belt) or I could use Arduino to connect it to Flypt or Simtools.

I think the most reliable and cost-effective thing I could do if there exist a way, is to build an Arduino Leonardo, connect it to a DB25 serial port and connect the Arduino to the PC.... But here comes my questions...

(The belt is not an actuator like the SFX type, it uses a belt to make the belt move)

-How should I connect the Arduino mega to the DB25?
-Would the sketch that you have to work with FlyPt and one port?
-I don't know anything about coding, should be done a lot of changes?


I just want the belt working, I will not have in the near future more servo motors (shipping is in the sky, and with all the world shortage...), and... I have some very strong transducers that help with some immersion

Any help or guidance I will appreciate.

the mega supports up to four motors if you need only one leave the other spare.
the AASD DB25 pin assigment is step=3, dir=4, enable=6, 5V=9, GND=5,10,14,
the mega assigment for motor 1 to 4 is step=digital pin 12,2,7,45 dir=digital pin 30,31,32,33
e.g. connect 3 to 12, 4 to 30, 6 to GND, 9 to 5V, 5-10-14 to GND

Thanks!!

The sketch is just copy/paste and the AASD parameters are the same?

yes, copy and paste the parameter are the same except P98=10.

Hello!
Got a few basic questions... cant make this work..

I have connected this:
3 to 12, 4 to 30, 6 to GND, 9 to 5V, 5-10-14 to GND (Mega to DB25)

But I cant make it talk to flypt when I hit connect

I also found this... Are 2 pins missing or maybe my problem is on another subject?
pin 23 SigOUT2 (Treach)
pin 11 SigOUT1 (Servo Ready)

My first goal is to make the belt servo to work (move)... I will also need to understand Flypt but first.. connect it

Thanks!

OK... Connected...

Could someone help me with how to set it up for this kind of Belt/Harness Tensioner?


Can't make it work, seems that I need to change a few parameters, but don't understand which ones.. and for what value

This is what I want to control with FlyPt and the Mega

Hope someone could help me or point me in the correct direction...

Thanks!

need to have some pics from the wiring and pinout

Hello!!!

Here goes the pics...

It's clear I'm doing something wrong... but I don't figure out what....

Thanks for your help!!
