SquirrelJME intends to be a Java ME 8 compatible JVM (Embedded/J2ME) and desires to be ported to many systems (Desktops, Phones, Amigas, etc.). It is written in pure Java and is under the MPLv2. http://multiphasicapps.net/

Networked weather station: STM32 firmware in C with a custom UART protocol, NeoPixel LED matrix animated via timer and DMA, OLED and stepper-motor dial, fed by a Raspberry Pi.

Base project for developing on STM32H743 chips. Includes periphery drivers (GPIO, UART, SPI, CAN, I2C, OneWire etc.. will be updated), external modules (slot-signal data exchange template, loger, ring buffers etc..), external libraries (etl, FatFS, FreeRTOS).

Platform-independent no_std driver for the Sitronix ST7305 reflective LCD controller (embedded-hal 1.0, blocking and async)

An experimental port of Micropython for TI-84 Plus CE (and 83 Premium CE) calculators, running on the eZ80 CPU.

Direct-BT provides direct Bluetooth LE and BREDR programming, offering robust high-performance support for embedded & desktop with zero overhead via C++ and Java.

C++ Support Library inclusive Java JNI Binding

A Rust reimplementation of minipro for XGecu TL866xx/T48/T56/T76 chip programmers. Native Windows, Linux, and macOS support with no libusb dependency.

Reverse engineering of the IKEA GETKÅL colour-changing LED string light: decoding its power-line data protocol (pulse-distance coding, 32-bit blocks, 12-bit colour, run-length zones) from oscilloscope captures.

ML engine for discrete circuit design: simulates and labels circuits, trains a GNN surrogate, then uses it to design, self-tune, and run inference on a microcontroller.

Tiny neural amp/pedal capture: a small GRU learns a guitar amp's sound, small enough to run in real time on a sub-$5 microcontroller.

Displays a Mastodon timeline with posts embedded in your website. Very easy to setup, no dependencies, no trackers, cross-browser, WCAG compliant and fully responsive.
