This project is "CW keyer" utilizing a Teensy microController.
You connect a Straight or Iambic A/B paddle to the microController.
A (piezo) buzzer produces the latency-free side tone.
Adding a low-pass filter you can enhance the audio quality
and connect some speakers.
Different from other CW controllers:
The controller is also connected to the (Windows) PC;
in this case all keys are reported to the PC via HID USB connection.
You don't need a driver :-)
Intention is to use that information for a CW training program
or an SDR transceiver software.
Besides that info, you can configure CW speed, tone frequencies, etc. from PC.
