We are creating a Knight Rider scanner using 16 LEDs on a #Raspberry Pi and doing this in #assembler. And with the libraries I created that is very simple in assembler. Almost as simple as Python
Please down load the code for the libraries:

The schematic and Gerber files if you want to make this yourself but you can just connect LEDs to the #gpio with a current limiting resistor as well.
