Discover the best Open Source RTOS solutions for embedded systems and IoT devices
This firmware transforms Raspberry Pi Pico or other RP2040/RP2350-based boards into an Altera USB-blaster compatible JTAG/AS/PS programmer. It leverages the tinyUSB stack for USB communication, making it compatible with Intel Quartus, OpenOCD, and other standard FPGA programming tools. The project supports various programming modes and includes optional support for level shifters and RGB status LEDs.
okhi is an open-source hardware implant designed to sniff and log keystrokes from USB and PS2 keyboards. It utilizes an RP2040 microcontroller for data parsing and an ESP32-C2 (ESP8684) for real-time WiFi transmission to a web interface. The project features advanced hardware design choices like TCXO oscillators and custom PIO programs to handle non-standard keyboard signals.
An ESP32-based project designed to fetch and display real-time electricity prices from the Tibber API on a Lilygo T5 4.7-inch E-Ink display. It utilizes the Arduino framework and focuses on providing an accessible, low-cost hardware solution for energy price monitoring.
An IoT-based attendance tracking system built with an ESP32 microcontroller, an MFRC522 RFID reader, and an OLED display. It captures unique card IDs and transmits them to a remote server via HTTP for logging and processing. The system provides real-time user feedback through a local display and manages Wi-Fi connectivity for seamless data synchronization.
