A portable composite video test pattern generator for the original ESP32-based M5StickC Plus family. This tool is aimed to be used as a quick and portable way of performing tests of basic functionality for CRT TVs in situations where hooking up an entire console would be inconvenient.
It is not intended to be a precision tool for diagnostics and fine tuning.
Features:
- PAL/NTSC support
- Multiple test patterns
- 16-bit colour (RGB565)
- Built-in battery and screen

There are a couple of ways to assemble the composite video adapter. See Setting up the hardware for details.
The schematic is also available.
Navigate to the Installation page to connect to your device and flash the firmware from your browser directly.
You'll need to install CH340 drivers in order to connect to your device.
Power the device on by holding the small power button on the left side, then connect the composite cable to your CRT TV. Cycle through test patterns with the large face button, and toggle between video formats with the small button on the right side.
Power the device off by holding the small power button for 5 seconds.
The device remembers the last video format, so you do not need to select it again every time it boots.
