AVR ATmega port of freeRTOS A port of freeRTOS which can be flexibly flexibly configured use almost any available Timer on AVR ATmega devices and will operate with almost any classic Arduino device from Arduino, SeeedStudio, Sparkfun, Freetronics or Pololu. Going forward this repository will be updated less often and only with major releases. Please check at Github for the latest commits. https://github.com/feilipu/avrfreertos The Goldilocks Analogue story is told here....

...It implements several display drivers (VGA output, PAL/NTSC Color Composite, I2C and SPI displays). FabGL can also get input from a PS/2 Keyboard and a Mouse. FabGL implements also: an Audio Engine (DAC and Sigma-Delta), a Graphical User Interface (GUI), a Game Engine and an ANSI/VT Terminal. VGA output requires an external digital-to-analog converter (DAC): it can be done by three 270 Ohm resistors to have 8 colors, or by 6 resistors to have 64 colors. Composite output doesn't require external components (maybe a 5Mhz low pass filter). ...

...To use VitOS on your Raspberry Pi 4 Model B (1/2/4/8GB version), just download the image file and write to the micro SD card with dd or other applications. Then plug in the micro SD card to your Raspberry Pi4. You can use iOS app and Android app named "VitOS Manager" to manage the VitOS. VitOS V1.0 supports USB DAC as audio output device. You can connect your USB DAC to the USB port on your RPi4 board. With VitOS Manager, you are able to install Roon Bridge to the VitOS. Then you can discover the RPi4 board with Roon apps and play music.
