Tell me what firmware to flash matekH743 or matekH743bdh to work dhot? is there any difference? Dshot on firmware will work matekH743?

Yes, I *AM* an eager beaver!

I started watching this video shortly after you released it... I just finished! I got busy in an "Old-Fart" sort of way... trekking about and entertaining overseas visitors, so it has been sitting on my screen, waiting. What a "Tour de iforce" this has become, from it's beginnings as a good idea. As is obvious from the comments, there are sooo many potential use cases. Arduino was a brilliant concept that has spawned some pretty neat offshoots, but you have really nailed it with this. Congratulations, and thanks. 👍

This is a really awesome accomplishment for a lone developer to create, great job. I hope you make this an open source project but I could totally understand keeping it closed.

You built a highly capable project here, it's so well thought out! 👍💪✌

Wow this thing is really cool. It seems amazing for prototyping all kinds of different systems

Amazing work, and progress. It's really looking more polished as a product, both the software interface and the pcb. Seeing how this video view count has shoot up over the week since posted is a great indicator to the amount of interest in your iomixer project. This will really open the ease to prototyping, or someone not familiar with with electronics/programming to approach many types of animatronics, or mechatronics projects.

By the time i finished watching this i have come up with 200 usefull things that can eliminate large bulky things

That nugget about interacting with OpenPNP at the end of the video was very exciting! Great to see a new video from you.

When you say 'prop', if you're talking about for movie or theater sets, yeah that occurred to me too. They could be controlled by an operator over radio, or MIDI events could be played from a DAW to play a canned sequence of events. The 37 servo outputs could be handy in animatronics...?

This is really cool! I kind of just stumble upon this video through the YT algo, I'm a programmer but I have only just dabbled a tiny bit into the world of Arduino but I think this would be amazing as a teaching tool in various subjects like robotics and automation. In my work place we have also made and implemented a node-based 'programming' language aimed at enabling 'beginner/novice' users to create simple logic. I particularly like how you have thought about how to use multiples of these in different roles Tx/Rx. This pretty exciting and I think this will definitely catch on!

People capable of writing device drivers would likely be better off setting up their own custom firmware.

@iforce2d

10 ай бұрын

This is not for arduino, and not compiled either. The nodes are held in memory and each one does it's thing based on how the properties are set. When you click 'upload' all nodes are discarded and all peripherals de-init to get back to the starting state, then everything is set up according to the new config. I suppose you could almost call it an operating system of sorts. Yes I developed all of it. I studied computer science at uni in the late 90's, but that was mostly Java that never ended up helping me much in the real world. For this particular project I would have learned it all after leaving school, namely C/C++, STM32 HAL, PHP, HTML, JavaScript, MySQL.

That would be interesting, not sure if possible, but being a console program with no graphical component the relay server is relatively easy to port. It needs to open a serial connection on one side and a websocket on the other, and I think it would need USB OTG capability too. To answer your question, it's not open-source but I might look into this further sometime. Failing that, a RaspberryPi ZeroW works well and is pretty small.

@yarnsags

@iforce2d The ESP32-S2 or S3 should be able to do websocket to USB serial host. It can host the web side, but gives some JS console errors if I just use the downloaded files. (Wasn't expecting that to actually work, just wanted to see if it would fit and load.)

So far I'm having the boards made a handful at a time by JLCPCB, it's not really costly enough to require outside capital support. The hardware is open source so in the long run I'm planning to sell just the firmware, which is where 97% of my development effort goes. I'm thinking of making a pick-and-place to assemble boards at home which would be the biggest up-front cost, but I think I can cover it.

i didnt really understand what output you are using from the MIDI device and which input it connects to on the iomixer

@iforce2d

11 ай бұрын

There is a MIDI out plug on the controller which goes to a pin on the iomixer. It's a UART connection which sends a message when some even happens, like a note being pressed/released, or a control dial/slider being changed. If you mean the physical connection, I had to make up a cable from a 3.5mm audio jack and soldering a bit onto the other end: www.iforce2d.net/tmp/wc245225.jpeg

The algo must have recommended your videos because I’ve been particularly frustrated with how complicated computer input is compared to how it actually is (literally every game input is either a binary input or an analog, or some combination of the two. Why does it take so much effort to use different controllers instead of just mapping the controls? nonsense. Even midi, keyboards, and mice are analog input.) Cool project. I’m going to drive down the rabbit hole now

Dude i want to buy a few of them

Blown away what this iomixer can do, ie. how easy it is to do, but I rather won't try it, cause I will just blow up things. No, thats not a question, its a statement 😁 I need to understand the logic behind it, like in Arduino, but here in iomixer it is all pre-programmed, so it seems.

Why is the digital input a float ?

@tinayoga8844

11 ай бұрын

I'm not sure where you saw that so maybe the following is incorrect. From what I saw in one of his sample project videos, a three position toggle switch produced a float output. I think it was 0, 0.5, and 1 reported as a float.. Three states for the three positions. So not really digital (0 and 1)

@iforce2d

11 ай бұрын

That's a fair question :) I didn't really explain it in this video, but each node has an output value which is the green text we see shown below it. Since nodes can be connected to other nodes in a bazillion possible combinations, it's easier if the value type passed between them can be standardized as much as possible, even if the data type is larger than necessary for some cases. For a numeric quantity, float is the most convenient - a float can represent an integer, but an integer cannot always represent a float. A float is four bytes, which is large enough to hold a 3-byte color value for nodes that output a color type. The data being passed between nodes is actually 5 bytes in total, where the fifth byte contains flags that describe what type of value the main four bytes are, which is necessary for the downstream node to know how to use the value it is given.

@Bob There are many cases where a node provides a boolean "true/false" result. For example a Unary Operator node with the "is negative" test will always output a zero or one. In those cases you can depend on the output being perfectly zero or one, and a Digital Input node is one such case. On the downstream side, when a node has an input property that will be treated as boolean, it will consider any incoming value above 0.5 to be "true". Thanks for the questions, this is exactly the kind of thing I need to iron out in my next big task... documentation.
