Output Full-HD Video to a Monitor from a Raspberry Pi Pico or ESP32 Over USB
Microcontrollers have no problem driving simple displays, like seven-segment LED displays and low-resolution OLEDs, but they really aren’t meant to output high-resolution video at a decent refresh rate, like a computer does. Even so, there are plenty of hacks out there to get composite, VGA, and DVI signals out of some microcontrollers. This solution from htlabnet is even better. It lets you get full-HD USB video at 60Hz from a Raspberry Pi Pico or ESP32.
This library, which is available both for the Arduino IDE and ESP-IDF, works with several different popular development boards: the Raspberry Pi Pico (or anything with an RP2040), the Raspberry Pi Pico 2 (or anything with an RP2350), an ESP32-S2 board, an ESP32-S3 board, an ESP32-P4 board, or a Teensy 4.x board. The ESP32 boards with require a USB OTG connector and the others will require a USB host connector. Wiring is easy, with...
