About

The Maker Microsoft MakeCode editor allows to program various Cortex-based microcontrollers.

• Add a new board

Programming: Blocks or JavaScript

You can program the board using Blocks or JavaScript in your web browser.

forever(function() {
    pins.LED.digitalWrite(true)
    pause(500)
    pins.LED.digitalWrite(false)
    pause(500)    
})

forever(function() {
    pins.LED.digitalWrite(true)
    pause(500)
    pins.LED.digitalWrite(false)
    pause(500)    
})

The editor work in most modern browsers, work offline once loaded and do not require any installation.

Compile and Flash: Your Program!

When you have your code ready, you connect your board to a computer via a USB cable then press the reset button so it appears as a mounted drive (named board).

Compilation to machine code from Blocks or JavaScript happens in the browser. You save the binary program to a .uf2 file, which you then copy to the board drive, which flashes the device with the new program.

Simulator: Test Your Code

You can run your code using the Metro Express simulator, all within the confines of a web browser.

forever(function() {
    pins.LED.digitalWrite(true)
    pause(500)
    pins.LED.digitalWrite(false)
    pause(500)    
})
