A VGA 666 Hut for the Raspberry PI. It provides a VGA output over the GPIOs It's build wiht a resistor ladder - 6 resistors for each colour. And that's why it will use so many pins: GPIO Pins 2-21.
The design of the adapter is based on Raspberry-Pi VGA Adapter of G.J. van Loo, it needs the same software like the original adapter:

The VGA socket is a bit tricky. One has to cut some pins and solder all ground pins together. Here are some pictures how it is done:
1. 2.
3. 4.

Pin 9 has changed from key to +5V so it's best to remouve it!

 $ sudo apt-get update
 $ sudo apt-get upgrade

In:

 $ sudo nano /boot/config.txt

add this:

 dtoverlay=vga666

and this:

 enable_dpi_lcd=1
 display_default_lcd=1

Dont forget to add the resolution, too:
for 1080p60

 dpi_group=2
 dpi_mode=82

for 1024×768 60Hz

 dpi_group=2
 dpi_mode=16

… more video-mode for DMT and CEA are on:
https://www.raspberrypi.org/documentation/configuration/config-txt.md

Disable the SPI and I2C interfaces, otherwise VGA666 will not work correctly. Use the “Advanced Options” from raspi-config to disable SPI and I2C.

 $ sudo raspi-config

Install blinking LED

If necessary change in the blink file the GPIO pin number to 27.
