In info, it says that setup.sh is under TronView/util. It is supposed to be under TronView/util/rpi. Simple fix by changing the location in the setup instructions

The latest commit where the scripts were reformatted to Python 3 standards prevents them from running on the default Python version on the RPi.

I used this link to figure out how to change the default version of Python from 2.7 to the the 3.5 version which is also installed.

Would be nice if we could run the project on other OS's like Windows and Mac by loading the appropriate versions of Python and Pygame on them. As it sits today there are some issues that prevent this from working:

1. The screen size discovered by Pygame ends up being the Windows display size which in most cases will be way too big. Some sort of solution to detect what platform it is running on would be good to work out the logic on the screen size arguments.

2. Currently demo mode does not work when running on Windows and I have not discovered why. The Hud display opens and appears normal but it is not stepping thru the demo files to simulate the EFIS data stream. It basically just sits and appears frozen.

3. Switching the HUD display to text mode while its already running in demo mode causes a crash with an error about 'clear' not being a program or executable.

4. Launching the HUD display normal and text mode where it is trying to access the serial port causes an error because the serial port access is different on the RPi vs others like Windows. Again if some sort of solution to detect what platform it is running on might be a way to work out the arguments.

Anyone volunteer to take on the challenge?

When running in the diagnostic text mode and the esc key is pressed, program crashes trying to load a screen module.

Add scripting to setup.sh that adds Python 3.x to the available versions and makes it the default for running Python scripts.

Kivic Hud confirmed to work using the composite video output of the RPi 3B+. Had to customize the config.txt file to get the correct overscan settings. So far so good....

This is a todo for me. I would like to convert the calculations that were developed inside of serial_g3x input module to reusable functions that can have the appropriate variables passed in with the results passed out. This would make it easier for anyone to use them in the future on other input modules. I need to learn how to properly do this before I make a go at it.

Hi 👋

I posted this a while ago, figured you might be interested! You have actual experience building HUDs, so would very much value your input!

Question for you while I'm here... have you found any docs on Dynon's Wifi TCP/UDP data stream protocol? Not sure if it's just the same protocol as the serial port or what, but cant find anything for docs on it. I don't have access to any decent avionics to play with 😞

I have set it up using the instructions in TronView/docs/rpi_setup.md.

I have two issues that prevent me from running the application with the example data. When I run the main.py file, the screen shows the example display correctly, but it is a static image as the python file hits an exception and does not continue to run.

(1) During setup.sh, when trying to install python-pygame and python-serial, they are not available. See below:

(2) When trying to run main.py with example data, I get an exception in Thread-1.

This was all being done on a fresh install of Raspberry Pi OS (32 bit), kernel 5.15, debian version 11.

Any help would be great! I would love to get this up and running to pull EFIS and EMS data from my Dynon D100 series device in real time.

Chris,

Can you give us a little history on what IDE you are using for your Python script development and what OS you are running it in? Maybe a little detail around your workflow.

Have you been able to emulate the HUD using Python for Windows? Do you think this is possible?

I assume this repository is the working copy of the HUD and the reorganization/rework you are doing will come in a later repository you will share with us?
