We think so!\u003c\/p\u003e\n\u003cp\u003eSo we designed this RP2040 Feather that has a digital video output (a.k.a DVI) that will work with any HDMI monitor or display. Note it doesn't do audio, just graphics!\u003c\/p\u003e\n\u003cp\u003eIt's kinda like we took \u003ca href=\"https:\/\/shop.pimoroni.com\/products\/adafruit-feather-rp2040\"\u003eRP2040 Feather\u003c\/a\u003e and \u003ca href=\"https:\/\/shop.pimoroni.com\/products\/adafruit-dvi-breakout-board-for-hdmi-source-devices\"\u003eDVI Breakout board\u003c\/a\u003e and glued them together. You get all the pins for use on the Feather, the Lipoly battery support, USB C power \/ data, onboard NeoPixel, 8MB of FLASH for storing code and files, and then with the 8 unused pins, a DVI output that can be used CircuitPython or with the \u003ca href=\"https:\/\/github.com\/adafruit\/PicoDVI\"\u003ePicoDVI library in Arduino\u003c\/a\u003e or \u003ca href=\"https:\/\/github.com\/Wren6991\/PicoDVI\"\u003ePico SDK\u003c\/a\u003e \u003c\/p\u003e\n\u003cp\u003eIn Arduino (recommended) Adafruit \u003ca href=\"https:\/\/github.com\/adafruit\/PicoDVI\"\u003euse their fork of PicoDVI\u003c\/a\u003e to create an internal framebuffer of 320x240 or 400x240 16-bit pixels that is then continuously blitted out as pixel-doubled 640x480 or 800x480 digital video. 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 - but note that it uses a lot of memory so in particular if you want to add other hardware accessories and libraries, you may need to configure it to be a lower-memory 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 Feather (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 on the very end of the 16-pin header. Read this pin to know when a display has been connected!\u003c\/p\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":41128964227155,"sku":"ADA5710","price":14.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/files\/5710-08.jpg?v=1745608069","url":"https:\/\/shop.pimoroni.com\/en-eu\/products\/adafruit-feather-rp2040-with-dvi-output-port-works-with-hdmi","provider":"Pimoroni Ltd","version":"1.0","type":"link"}
