/*
Adafruit NTSC SMPTE color bars (resolution is 256x224, colors are approximate at best)
uses composite video generator library on ESP32 by Roger Cheng
Connect GPIO25 (A0 on QT Py ESP32 Pico) to signal line, usually the center of composite video plug.
Please disable PSRAM option before uploading to the board, otherwise there may be vertical jitter.
