Ty command API as TyCmd.dll

[ttlappalainen]

Would it be possible/easy to create Ty API for at least:

• Request boards
• Program board

Something like: using tProgressCallback=size_t ()(); bool GetBoardList(tFormat Format, char buffer, size_t bufferSize); bool UploadBoard(const char Tag, const char data, size_t dataLen, tProgressCallback Progress);

There are two internal libraries used in this project and available in the src directory:

• libhs: this library allows you to list USB serial and HID devices on Windows/macOS/Linux, it is relatively clean and documented (more info here: https://koromix.dev/libhs)
• libty: this library uses libhs to list and control Teensy devices... but it is not documented and kind of an overengineered mess. I still had a lot to learn back when I made it :)

Unfortunately I don't have time to clean libty or document it, but the code is there. It works, it's just a bit overcomplicated. You can look at the code of tycmd to use it, for example:

• src/tycmd/list.c: list Teensy devices
• src/tycmd/upload.c: upload a firmware

Another option is to execute tycmd and parse the result:

• tycmd list -Ojson -v to list devices in JSON format
• tycmd upload firmware.hex (or firmware.elf directly), there are various options available to control which Teensy you want to program (--board option). Use tycmd upload --help for more information.
