JARU IDE
Lightweight IDE and language for ESP32 development
JARU IDE turns ESP32 development into one lightweight workflow. Write code in JARU, a small language made for microcontrollers, run and test it on Windows first with the built-in virtual machine, and step through it in the visual debugger. Check wiring in the GPIO simulator, draw sprites and images for your display, compose chiptune music in the built-in tracker, and connect devices over MQTT. When it works, one click flashes the board. No heavy toolchain, no long setup.
Hi Product Hunt,
I used to build my ESP32 projects in C/C++. It works well, but for small experiments and proofs of concept I was spending more time on toolchains and libraries than on the actual code.
I have always been curious about programming languages, so I started a small one with the libraries I use most already built in. That "small project" grew into a full system: a custom language, a virtual machine that runs on the ESP32, and a compiler targeting that VM.
At some point I made the same VM run on Windows so I could test everything before flashing hardware. Once that worked, an IDE around it was the obvious next step, and it kept growing:
- Code editor with autocompletion
- Debugger with breakpoints and variable watch
- One-click flashing to the ESP32
- Image, sprite and tilemap editors, plus a chiptune music tracker
- GPIO simulator, so programs with LEDs, actuators or panels can be tested on the PC with no board attached
The result is a very fast way to prototype MQTT integrations, REST APIs, sensor tests and small retro-style games. I have been using it for demos myself, including a recent ray tracing experiment.
Happy to go deeper into any part of the system: the language design, the VM, the compiler or the simulator. Which boards, displays or peripherals should I support next?
