A Blocks / JavaScript code editor for the micro:bit powered by Microsoft MakeCode.

The basic idea behind microcode is to replace the custom hardware logic implementing the instruction sequencing with a series of simple instructions run in a "microcode engine" in the processor.

Microcode enables the computer designer to create machine instructions without having to design electronic circuits. Writing microcode is called "microprogramming," and the microcode for a given...
