There you go. Thanks to the insight on decompiling a Unity program provided by user sevreNniarB, I was able to write a small Go library to read and write .dsp files. This bring us a lot closer to being able to create programs outside of the Robomaster app (which we all know is far from an ideal development environment).

Here is the code:

https://git.bug-br.org.br/bga/robomasters1/src/master/dsp

Right now it is not very useful as it can only read a file and then write it back. I will add methods to modify an existing file or to create one from scratch as time permits. In any case, the difficult part is already there.

Great news, thank you for your effort BGA!

I have a little teaser for you:

And yes, it is working (not talking about the sound test, take a closer look at the user...)

Cheers

Hah. Good one. I assume you logged in to the S1 itself and is running commands inside it, correct? If so, that is amazing as we would be able to figure out what is the deal with the onboard python interpreter.

While you are at it, does it have a procfs mounted? If so, can you do:

cat /proc/cpuinfo
cat /proc/meminfo

Or, even easier, can you send the output of the mount and free commands (assuming they are installed) ?

You can just use this Lab code:

print(globals().keys())
print(__builtins__.keys())

Looks like the runtime is CPython. Here is your Info:

I am a bit confused. The code you provided just prints the available globals. Why did you suggest me to run it?

BTW, I added a simple codec program that is able to convert python files to dsp files and dsp files to python files. It is written in Go so it can easily compile on Linux, Windows or Mac (and can be cross-compiled to any plataform to any other platform as i does not rely on any external libraries.
