Changing the code to receive data from the simulator about fgfs-binary-protocol HOT 2 OPEN

Hi there! Thanks for reaching out, and sorry for the delay :)
As you mentioned I'm not really working on this any longer, mostly cause it was just a one-day project (almost ;) ) to see if I could get some controls on Arduino to connect to FGFS.

I would have loved to do bi-directional communication, but at the time I had no idea how to implement that in a nice way. I was thinking either to have two serial connections, or perhaps implement some kind of protocol for which every time Arduino would send a packet to me, I would be able to send back to Arduino some data about FGFS (maybe for displaying radios or for some forced feedback, stuff like that).

I think this would be quite wasteful though. Instead of just exchanging fixed size data packets, I think it would be better to exchange messages. I originally implemented fixed size packages as the binary protocol from FGFS to my program also worked that way, but I guess we could communicate with messages instead?

What were you thinking?

What were you thinking?

I needed a way to get data from the FlightGear simulator.
I was looking for various options and that’s how I actually found your project.
But your code only sent data to the simulator, I needed the inverse task, and I thought that this could be done by analogy.
In the end, I did it easier, using the generic protocol.
I created a protocol *xml file in the folder, I indicated to the simulator what data I need to transfer to the com port, also known as the serial port.
And using the console command I ran:
fgfs --generic=serial,out,150,\\.\COM15,230400,insgns-imu2
I already receive this data using USB-TTL and submit it to the RX input of the STM32F411 microcontroller.
On which the code program with the serial port parser runs.
I needed to receive raw data from gyroscopes and accelerometers in order to process fusion algorithms on a microcontroller, similar to mems sensors.
So far everything seems to be working out as planned.
The video shows not just a duplication of orientation angles from the simulator, but actually a real-time calculation of angles inside an aircraft instrument.

In the future, there are plans to rewrite your code to output data from their simulator, and wrap it all in a library.
Thanks for your response.
