Programming: Blocks or JavaScript

You can program the Adafruit Circuit Playground Express using Blocks or JavaScript in your web browser:

Blocks

input.buttonA.onEvent(ButtonEvent.Click, () => {
    light.showRing(`blue blue blue blue blue blue blue blue blue blue`)
})

JavaScript

input.buttonA.onEvent(ButtonEvent.Click, () => {
    light.showRing(`blue blue blue blue blue blue blue blue blue blue`)
})

The editor works in most modern browsers without needing any installation. Once loaded in the browser, it works while you’re offline too.

Compile and Flash: Your Program!

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

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

Simulator: Test Your Code

You can run your code using the Adafruit Circuit Playground Express simulator, all within the confines of a web browser. The simulator has support for the LED pixels, buttons, as well as the accelerometer, light sensor, temperature sensor, and digital I/O pins.
