+# hantek-dso2xxx libsigrok driver
+
+A libsigrok driver for the Hantek DSO2xxx oscilloscope series (DSO2C10,
+DSO2C15, DSO2D10, DSO2D15) that receives waveform data over TCP using the
+`quick-fetch` firmware patch by phmarek:
+https://github.com/phmarek/hantek-dso2000-quick-fetch
+
+Initial contents generated via Claude.AI,
+https://claude.ai/share/bcc56b39-53ab-45be-a91d-251cbe64fa98
+
+---
+
+## How it works
+
+The patched firmware (`quick-fetch.so`, `LD_PRELOAD`'d on the scope) listens
+on a TCP port. When the user presses `SAVE_TO_USB` the scope freezes the
+current waveform and streams a compact binary frame to the connected client.
+
+---
+
+## Prerequisites
+
+1. Install the quick-fetch patch on your scope following the instructions
+   at https://github.com/phmarek/hantek-dso2000-quick-fetch
+
+2. Use DavidAlfa's USB-networking kernel so the scope appears at (e.g.)
+   172.31.254.254 via USB networking. Without this, the TCP server is not
+   reachable.
+
+---
+
+
+## No configurable acquisition options
+
+All scope settings (timebase, volts/div, coupling, trigger, memory depth)
+are configured directly on the instrument front panel. The driver reads
+them passively from the binary frame header.
+
+If there's much interest I'll update both the `quick-fetch` patch 
+and the driver to allow modifying the trigger level, position, etc.
