This program allows you to use the Teensy as a USB to protocol converter.
The design is centered around exposing simple building blocks to a USB UART interface. In this case, the Teensy is not designed as a standalone device. Rather, it should always be used with a host computer that sends requests to accomplish different actions.
Currently, we support:
| Protocol | Teensy 4.0 |
|---|---|
| GPIO | Yes |
| I2C | Yes |
| PWM | Yes |
| SPI | Yes |
Future protocols include:
- CAN
- Serial
Generally speaking, this should help you prototype hardware, by bypassing the tedious steps of creating a USB Serial Parser, and letting you bring up hardware more naturally.

This library also provides a basic "setup" and loop capabilities. This can be useful if you want to create an open-loop demonstration application. No "if" statements are used in the loop meaning it is very difficult to create conditions.
