talking to teensy when plugged in to USB?

[DJB]

I'm looking for a very generic way to send config data to teensy.

I envision something like this:

• open a GUI application that can detect the teensy (select it from a list of connected devices?)
• select the teensy you want to talk to
• In teensy land, press and hold a button to put your code into "config mode" which then waits to receive a message from the external application.
• Back in the external app, type in your config string and click SEND to transmit data to selected teensy
• teensy app then does something useful with the data and exits "config mode" etc.

Is there a more or less generic GUI app that runs on windows/mac that would allow for this type of "connect and talk to teensy" thing to take place?
I'm basically trying to avoid writing software that already exists.

Thanks!

If you don't need a customized GUI you can simply use https://github.com/Koromix/tytools to do the PC part of your tasks. Communication would be Serial or SerEmu (HID), whichever you prefer (TyCommander can handle both).

Nice! I'll take a look, thank you @luni !

I do this as @LUNI mentioned by using serial commands. On the Teensy end I look for serial events.
