Motion Control Software Open Source

Hi Dutchboy :-) Got in touch with the guys from ocean and they have pointed me to a Badly programmed Controller Chip he was great at coming up with the goods so happy customer all round and great technical backup service and help so happyt customer. basically atmel microcontroller chip was sending out the wrong signals for H bridge and switching sequence was causing red hot Mosfet problems ( Not Good ) but in saying that have not fried anything and other tests Removing the Microcontroller and Forcing Gate inputs high have shown that the H bridge works fine and Motor Spins up & can change direction dependant on which input is triggered OK they are sending me a new controller and Fets so should be in business soon :-)

Good to hear they have good customer service. I had to put my controller on hold while I tried to find insulators for the mosfets that were thin enough to sandwich between the mosfets and my fat aluminum heat sync.

Found some out of an old power supply I had lying around! All the local electronics shop had were 3mm thick aluminum oxide.

So, I should be able to do tests this weekend if the future wife doesn't have me running around the city looking for flowers or ribbons or some other frilly thing.

How is the progress going on this project guys.

I have my 2DOF sim built and I'm going down the same road as you. I have my K8055 kit ready to put together and then I'll get the motor controller from Ocean Controls soon.

I'm very interested in your progress. Also willing to input as much as I can. I am not a programmer, but may be able to test and give feedback.

Regards
David

Hi RobiD,

I have released the first source code, but it is not in a state to control DC motors yet. As soon as we are ready to test, I will post here and let you know. What motor control board are you using? Do you have any pictures of your setup?

Which controller are you writing for?
Which sim are you writing for?

Thank you.

I do have some pictures and I'll try to post them asap.

I am about to buy the KT 5198 board from Ocean controls for the motor controller.

I will be using FS9 and the setup I'm aiming for is what Jim mentions on his site : K8055 for positional feedback and the KT5198 for motor control.

Dutchboy,
How about the open source? Same questions.

Hi All,

A reasonable suggestion for this new Forum would be to do some preliminary research on what has previously been successfully achieved in other application domains that might have covered topic areas that might easly be replicated!!

If I may suggest the following site The Open Source Motor Controller (OSMC) as a good place to start as it has lots of useful information!

http://www.robotpower.com/osmc_info/

I have built and integrated their designs into many experimental servo feedback systems.

There are many others

Hi Andy,

I am writing the code using C# and SimConnect (FSX only).
Currently, I have the implemented code to control the SSCII servo control board, and have started to implement code for the KT5198a motor control board. My inputs will use directinput, so anything that gets recognized as a joystick will work fine.

Of course, being open source, anyone can add code to the project in order to control other boards.
