Raspberry Pi Pico VGA video output using only resistors

Building VGA output from a Raspberry Pi Pico. The Raspberry Pi Pico is amazing. • Sections of the video so you can skip ahead • 00:00 Intro • 01:06 Pico Setup • 03:35 VGA Resistor DAC • 08:43 Program and Demo • In this video I go through building the VGA output circuit using only resistors. It has a 5 bit DAC on each of the red, green and blue lines which means it should have 32,768 individual colours. • In the video I mislabel 2 resistors. The resistor ladder should be 499 ohm, 1K ohm, 2K ohm, 4.02K ohm and 8.06K ohm in that order. It's supposed to double each time, the linked schematic in the description is accurate here https://datasheets.raspberrypi.org/rp... • The full schematic just for the VGA output including RGB, HSYNC and VSYNC is here • Schematic for Raspberry Pi Pico VGA • The demo code comes from the GitHub repo for RaspberryPi.org see the links below. • Please note this video is not sponsored in any way. There is a follow up video where I fix some of the colour issues I mention in this video. See the end card for the link. • • Useful Links • Setup and getting started with Raspberry Pi Pico • https://www.raspberrypi.org/documenta... • Circuit Diagram for VGA output is here • https://datasheets.raspberrypi.org/rp... • • Github Repos you need • https://github.com/raspberrypi/pico-p... • https://github.com/raspberrypi/pico-e... • BuyAPi.ca where I bought my Raspberry Pi Pico • https://www.buyapi.ca/product/raspber... • VGA Female to Female Gender Changer • https://www.amazon.com/VCE-Changer-Co... • Assorted Resistors and Breadboard Kit • https://www.amazon.ca/Assortment-Resi... • 7 VGA and HDMI screen (like the one I used in this video) • https://www.amazon.ca/Display-Monitor...
