Whatever you 'draw' to the internal memory framebuffer appears instantly on the digital display in crisp color. Since the library is a subclass of AdafruitGFX, it'll be familiar to folks who have used our TFT or OLED displays before. \u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/github.com\/adafruit\/circuitpython\/releases\/tag\/8.1.0-beta.2\"\u003eThere's also DVI output support in CircuitPython as of 8.1.0b2\u003c\/a\u003e\u003cspan\u003e \u003c\/span\u003e- but note that it uses a\u003cspan\u003e \u003c\/span\u003e\u003cem\u003elot\u003cspan\u003e \u003c\/span\u003e\u003c\/em\u003eof memory so in particular if you want to use PicoW with WiFi support, you'll likely only be able to get away with monochrome display.\u003c\/p\u003e\n\u003cp\u003eNote that the DVI video generation uses one full core, both PIOs and 150K (320x240) or 190K (400x240) of SRAM. It's kinda maxed out so be aware of the remaining resource limitations.\u003c\/p\u003e\n\u003cp\u003eAdafruit also connected the HDMI-connectors I2C pins to the SDA\/SCL of the Pico (through a safe level shifter) so you can read the EDID EEPROM of displays, and have broken out the CEC and Utility pads. The Hot Plug Detect pin is also available. Read this pin to know when a display has been connected!\u003c\/p\u003e\n\u003cp\u003eEach order comes with an assembled PCB and header.
