# picoscope-libusb: reconstructing PicoScope 2204A USB control

> picoscope-libusb reconstructs PicoScope 2204A USB control from SDK traces and device experiments. Its protocol notes document endpoints, command framing, firmware upload, capture modes, and waveform transfers; a C libusb driver exposes these functions to a Wails desktop GUI and an Android JNI library. Firmware blobs must be extracted from the user's own device.

## Requirements & limits

- **Prerequisites:** A PicoScope 2204A and firmware extracted from the user's own device are required.
- **Testing evidence:** The primary hardware target is Linux desktop; Windows and macOS hardware use has not been validated.
- **Limits:** Signal-generator amplitude and offset did not respond on the tested unit.
- **License:** Licensed under MIT; proprietary firmware blobs are excluded.
