Work in progress.
Goal is to practice morse code using a physical telegraph key, like the J-38.
Components:
- Android app
- STM32 microcontroller
- J-38 telegraph key
The STM32 acts as a USB keyboard, converting keypresses on the J-38 to key events for the Android app.
The android directory contains the Android Studio project.
The J38_USB_HID directory contains the CubeMX project for the J-38 USB Device.
