Multi-Platform Gamepad Firmware for Raspberry Pi Pico and other RP2040 boards
Sming - powerful open source framework simplifying the creation of embedded C++ applications.
Open World 3D Game Engine for the PicoSystem & RP2040 Microcontroller
Arduino library for Art-Net (artnet) over WiFi, send and receive DMX data. Runs on ESP8266, ESP32, Pi Pico W, WiFi101 and WiFiNINA devices.
RF tool based on CC1101 module and Arduino Pro Micro 8VMHz/3.3V. Allows using CLI with human readable commands to control CC1101 board over USB interface. Putty or any other serial terminal can be used. It has similar functionality to YardStick One but is cheaper and doesn't need specialized software. Allows for RF jamming and simple replay attack
Arduino LoRa EBYTE E32 device library complete and tested with Arduino, esp8266, esp32, STM32 and Raspberry Pi Pico (rp2040 boards). sx1278/sx1276
Simplest ultrasonic ANTISPY voice recording jammer based on ATTINY13 / ATTINY85/45/25 / ARDUINO with PAM8403 / TPA3116D2 module driving piezo ultrasonic transducers (and optionally AD8933 signal generator)
MIDI over Bluetooth Low Energy (BLE-MIDI) 1.0 for Arduino
PCF8574 library. i2c digital expander for Arduino, Raspberry Pi Pico and rp2040 boards, esp32, SMT32 and ESP8266. Can read write digital values with only 2 wire. Very simple to use and encoder support.
This is simple yet complete WebServer library for AVR, AVR Dx, Portenta_H7, Teensy, SAM DUE, SAMD21/SAMD51, nRF52, STM32, RP2040-based, etc. boards running Ethernet shields. The functions are similar and compatible to ESP8266/ESP32 WebServer libraries to make life much easier to port sketches from ESP8266/ESP32. Coexisting now with `ESP32 WebSer…
