Test Firmata

[wallarug]

requested in donkey car chat. @chrimo

servos would be enough for the first tests
simple test: connect MM1 to any PC and start firmatatest. Then use the slider to control connected servos. I costs you 5 minutes of your time :slight_smile:
BTW: the are multiple versions of firmata available. Firmata standard, firmata plus and firmata express

Thanks for checking this :-) If it works, it will be a cool solution for any system with USB only. e,g. Intel Up/Euclid and all NUC. Not for donkeycar only, I'm using pymata/firmata for a long time with ROS.

Hi @mockbot ,

I have tested it out and it is working. There is currently a PR in the firmata repo. Hopefully they push this through pretty quick.

Hi Wallarug, I've got in contact with pymata developer and got the following response today: Alan Yorinks <notifications@github.com> 16:04 (vor 5 Minuten) an MrYsLab/FirmataExpress; Christian; Author Englisch Deutsch Nachricht übersetzen Deaktivieren für: Englisch Looking at the little documentation that is available for this board, I do not plan on providing direct support within pymata4. I don't know if Firmata can be loaded on this board or not, but currently, it is using Adafurit seesaw and CircuitPython. I tried using CircuitPython for my CircuitPlayground Express extension, and even though I would rather program in python over other languages, the performance was horrible, so I had to create a version of Firmata to work with that board. In addition, the Adafruit libraries, are not always written optimally. For one of my projects <https://mryslab.github.io/bots-in-pieces/banyan-components/cricket-hardware-gateway/2019/08/15/banyan-bot-blue-part7.html>, I had to do some coding around what I considered bugs. Also, the IMU they are using is an i2c device, which would mean that support would have to be implemented using the Firmata i2c primitives - usually not a very pleasant job. If Robotics Masters sent me a board free of charge, I would consider supporting it, perhaps with python_banyan and OneGPIO, but I could not guarantee supporting it or not. Sorry about the long story, but this board does not seem to be a good canditate for Firmata support. Let me know your thoughts. Thanks. Am Mo., 4.
