Kaluma Puts JavaScript on the RP2040

Estimated read time 1 min read

With a simple firmware update, Kaluma puts a lightweight JavaScript runtime on the Raspberry Pi Pico (which uses the RP2040 microcontroller), providing handy modules for file systems, graphics, networking, and more. Code for a simple LED blink can then look like:

// index.js
const led = 25;
pinMode(led, OUTPUT);
setInterval(() => {
digitalToggle(led);
}, 1000);

Development can then be done using tools that are very familiar to JavaScript developers, such as npm and flashing new code to a USB-connected Pico with the (Node.js-based) Kaluma command-line interface. Take a look at the GitHub repository for the project, or browse some of the projects made with Kaluma.

Much like with MicroPython, there’s value to be had in putting implementations of high-level languages on microcontrollers. Each new language opens embedded programming to a whole new group of coders. But it’s not just languages making their way to the RP2040. Wonderful projects such as emulating the ZX Spectrum on an RP2040 also happen.

Thanks to [Shri Hari Ram] for the tip!
