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

brother. Thank you very much for your modification. There is no problem with flypt settings. Can you also modify simtools? Every time you change the game, it will return to the original point and drive it again, it will rise quickly!

Is there anyone who can help me with adding a home sensor in the arduino code?
I would like to start up with it moving to a home sensor and then go 90 degrees.

When connecting FLYpt and arduino it runs a long way.

@d4m Would your sketch work with the amc-open-hardware-servo-controller-4dof ?

I very much doubt it but you could ask Thanos about it since no pinout or source code is offered, just the hardware.
I doubt it because the wiring from the AASD controller interface to Arduino would be quite different.

OK, thankyou. I didn't get the board yet ( and the soldering is not done ), but as I could see on some pictures, wiring is very similar. Maybe I could adapt your code, but I am new to all this stuff and don't want to destroy something

I have been using flypt for the last six months with no issues using a windows 10 PC.

I just built a new Win 11 PC and I am having lockup issues with the program.

Any help would be appreciated,

what are lockup issues ?

Great work.

For a new rig that I am designing, I would need to tweak the code to control the servomotor's speed not their position.

For example, lets say FlyPTmover sends some number representing 100% surge forward, then I would need the servo to spin at their max speed, say 3000 RPM clockwise

Any idea how it could be done ? Thanks for your help

Thanks for your help Yobuddy. I am unsure how to do that with those servo motors and their AASD15 drivers, which are connected to the Arduino.

I am trying to wrap my head around the Arduino code written by @cubexxx and find an easy solution so that pulses are generated to mimic a speed proportional to the input sent by FlyPtmover.

The AASD15 has according the manual different control modes, torque,speed and position. I suggest you have to take the speed instead position mode and find the proper signal maybe analog.Look at Pn158 description.

look at 2.3.2 Speed, torque control wiring diagram, pin 25/13 shows a speed/torque analog directive +/- 10V.

Thank you so much Wingert for this. I had not thought of the AASD15 controller various modes to solve this. If the speed mode requires a +10/-10V analog directive, I am not sure how to program the Arduino to output this.

I will experiment with this, thanks again

I could play with Pn158 parameter to bring the voltage requirement in the 0 to +5V range but then I believe I am stuck when it comes to generating a negative voltage with the Arduino ?

Thank you, I will try this.

Too bad there is no straightforward digital solution for speed control of the servo motor, only an analog one AFAICT

I have just checked it with my spare parts.
PN002 set to 1 speed mode , PN003=1 (motor enable ) analog Voltage on Pin 13/25 motor spins proportional in one direction , Voltage Reverse on Pin 13/25 Motor spins opposite direction.
With no signal motor has even a idle spin with can be corrected with PN159.

Thank you so much Wingert for making the experiment. This speed control mode feature might well work for my needs. I will try and report.

Im trying to make your code work with 3 sfx100 actuators what string do i need to use ive tried every string i can think of or will this not work with 3 actuators?

Hi I made 2dof sest with smc3 code for DC motors on arduino. I want to try this stepper motors but I'm totally newbie with this stuff and lack of English words sometimes so my 1 st questions is i can buy this cheap one and make some tests:

Thanos is to expensive for me and I don't know is this motion type is for me. And how it's working how is noisy and how much my bills will rise with this type of motors so I want to make some tests
