Wait for one, cancel others

This is a little helper script that can be used to wait for a single asyncio task to finish, then cancel other waiting tasks.

Usage

My use-case for this is:

waiting on user input
...while waiting on cancellation events input (via pub-sub)

This demonstrates using the RMT peripheral on the ESP32-S3 as a 10-bit serial transceiver.

The demo uses a shared GPIO pin (6) but can be separated to two pins. It initializes at 100kHz and begins sending a sequence of 10-bit numbers.

Debugging the L496ZG on Windows using VS Code

This only works for Windows, but you can easily modify it for Linux. It would roughly be the same, except you would need to modify the "linux" sections in the json files.

Download OpenOCD for Windows: http://gnutoolchains.com/arm-eabi/openocd/ (you'll need 7zip to extract it).
- OpenOCD-20181130.7z is used in this guide. If you use a different version, you'll have to update the json files.
Install libusb and stlink drivers
- libusb: https://zadig.akeo.ie/
- stlink server???: https://www.st.com/en/development-tools/st-link-server.html

the STLinkWinUSB drivers also have to be installed but I have no idea where to find those yet...
