RaspiKeyer
Since I really like the Raspberry Pi Pico, I have started building a cw keyer based upon this microcontroller.
Note: The keyer is in a very early stage. If you just want a full featured cw keyer firmware, you should better choose another project.
Features (planned/done):
- Iambic Paddle
- Keying modes: Iambic A, Iambic B
- Straight key
- Sidetone (buzzer)
- CW out (straight key input on TRX)
- Setting speed with rotary knob
- Display (TM1637) showing keyer mode and speed
- Change keying mode via button
- Logging and Contest Program Interfacing (WinKeyer)
- Support for three text memory buttons
Line out (sine wave) -> long term; not that easy
