## Description

No more guesswork on the I²C bus!

The [**I²C Doctor**](https://i2c-doctor.com) is a compact, all-in-one diagnostic tool with an integrated 1.3" TFT color display. It scans, analyzes, debugs, and stress-tests your I²C applications in real time. Instead of spending hours interpreting signals on an oscilloscope, the I²C Doctor's diagnostics provide you with a clear health score (0-100%) and concrete, actionable recommendations.

A must-have for every electronics engineer, embedded developer, and ambitious maker who values their time and the quality of their products.

### Why did you make it?
Every hardware developer knows the frustration: you connect a new I²C sensor, boot up your microcontroller, and... nothing happens. The display stays black, or the system completely freezes.

To find out why, you usually have to buy a pricey oscilloscope or logic analyzer, decode raw waveforms, or spend hours guessing if it's a wrong address, missing pull-up resistors, a hardware defect, or a firmware bug.

We built the I²C Doctor because we wanted a dedicated, pocket-sized kit for the I²C bus. A smart tool that stays right on your workbench, plugs in instantly, and handles the heavy lifting of troubleshooting so you can focus on building your project instead of hunting down transient bus glitches.

### What makes it special?
Unlike generic oscilloscopes or logic analyzers that just show you raw data, the I²C Doctor actively diagnoses your bus and tells you exactly what is wrong and how to fix it in plain English on its crisp 1.3" color screen.

*   **Health Score (0-100%):** Get an instant readout of your bus stability based on real-time rise times, pull-up resistances, and signal currents.
*   **Short-Circuit Detection:** Detects short circuits between SDA/SCL and GND, SDA/SCL and VDD, as well as between SDA and SCL itself.
*   **Specific Recommendations:** You no longer have to capture I²C signals and measure rise times manually to find potential stability issues. The Doctor tells you what to do in plain English.
*   **Fast Address Scanner & DB:** Finds all connected sensors in less than 2 seconds and automatically identifies popular chips using its integrated database.
*   **Built-in Fault Injection & Stress Testing:** It doesn't just watch; it lets you simulate worst-case scenarios like heavy EMV noise, clock stretching, or long cable capacitance to ensure your design is bulletproof before it goes into production.
*   **Fully Standalone:** Thanks to the built-in display and USB-C power, you can debug any I²C bus right out in the field without ever needing a PC.
