 # ESP-Scope
 
 ## Overview
-ESP-Scope is a web-based oscilloscope built using the ESP-IDF framework. It allows users to visualize analog signals in real-time through a web browser. The project leverages the ESP32's ADC capabilities and serves a web interface for signal visualization. It contains complete source code and 3D design for a case for the Seeed XIAO ESP32C6.
+ESP-Scope is a web-based oscilloscope built using the ESP-IDF v5 framework. It allows users to visualize analog signals in real-time through a web browser. The project leverages the ESP32's ADC capabilities and serves a web interface for signal visualization. By default, one of the ESP pins generates a PWM signal, useful for debugging or generating configurable pulses.
 
-This project was written in part to test AI code generators and see if they're any good. Much of the code was written by Google Antigravity using Gemini 3, with refinements, hints and tips and overall design specified by a human. The whole app was up and running a few hours and finished, including 3D design in a weekend.
+It also contains a 3D design for a case for the Seeed XIAO ESP32C6.

 The LED indicates one of four conditions:
-* Continuously lit: waiting to attach to a wifi network or starting the wireless AP
-* Equal 1 second flash: in AP mode - connect to the "ESP-Scope" access point
-* Slow, brief flashes: connected to the WiFi SSID set in the web UI
-* Rapid, brief flashes: sending data to an active client

 ### Attaching hardware
 
-The displayed signal is sampled from ADC0. The test signal is output on D1. The default GPIOs for the LED and "AP-Mode" button are 15 and 9 respectively (hard-wired on an Seeed XIAO ESP32C6 to the yellow LED and "Boot" button).

 ## 3D design
 
 The 3D design is a two part case with space for a AA-battery (Li-poly 3.7v, which can connect directly to a Seeed XIAO ESP device) clips and holes for the USB-C connector and "ground", "signal" and "test" connections using standard 2.54mm pitch, easily cut from jumpers and soldered directly to the Seeed XIAO. The 3D design was done using Fusion 360 and printed on a Bambu Labs A1 Mini in 30 minutes.
 
-I recommend putting the "Signal" connection in the middle, and never connecting the outer-most pins (ground and test) to avoid shorting the test signal to ground and (probably) frying the esp32. The middle (signal) pin can be connected to either of its neigbours and you'll see either the ground or the test signal.
