Communications Protocol Puns

I have some protocol to communicate from the PC to the microcontroller or otherwise. But I want to learn, is there any other alternatives. Here is my protocol;

{START_COMMAND} {MODE_BYTE} {MODE_LENGTH} {MODE_DATA}

Example: ${0x01}{0x03}{0x11}{0x22}{0x33}

I send this telemetry from the PC to the microcontroller. Before I use any mode, I need to define mode in the microcontroller firmware. From microcontroller side I do these things;

1. I wait for the START_COMMAND in the UART interrupt,
2. After get the start command, I get the MODE_BYTE,
3. I get the mode length and set the counter to get MODE_LENGTH of bytes,
4. I get all data and save to the array,
5. I set the update variable to the corresponding mode,
6. Do things on while loops with the data.

Do you have any protocol that is better than my protocol, or do you have any recommendation for my protocol? Thanks for all of your response.

Hey all, what communications protocol does signal messenger use. Do they use websockets, or http streaming or what do they use?

Hey, some of you might remember Chirp (https://github.com/chirp). A protocol for devices to communicate by chirping to each other. Unfortunately it seems to be dead and wasn’t open sourced (there is a reverse engineered version out there). I’m looking for other things like that: sound or light protocols that could be used to send data between devices.

Any ideas about other projects like that?

I'm working on a project where I need to control multiple pointing and centering (PAC) optical setups. Each setup requires 4 motors (with encoder) and one camera, I estimate the system will need around 60 motors, 15 cameras, and shouldn't span more than 150 meters. Each PAC loop will be dependent on the loop before, with a couple paths acting in parallel.

My question is in regards to communication protocols. What are some methods used to control this many motors/cameras?

I was looking at Power Over Ethernet with many nodes(MCU or small computer) each controlling one PAC and feeding back to a main computer as one possible solution.I'm curious how others have approached the problem of controlling many physical devices.

Has anyone used NI and LabView or PLC's to accomplish this.

Thanks.

P.S.

I recently went to a Hockey game (L.A. Kings) and was amazed at the motion control they implemented for the lights.

Hello there, I was wondering as someone who is new to electronics how you can figure out what protocol to use to communicate with different devices. I think I am asking this the right way but please correct me if I am not. I will use an example that is specific to me but Im hoping for a general answer so that I can try it out with many other devices.

I have a Nikon camera that has a port that you can connect to its a 10 pin connector, and there is a device I can connect to it that helps control the camera for time lapse photography. What I would like to do is create my own device that can do the same thing.

So my question is how can I figure out how to talk to my camera via this port. Is there something specific I need to search for, is it a matter of trail and error. I just don't really have a starting off point and that pretty much what im looking for.
