Arduino library to upload sketch over network to Arduino board with WiFi or Ethernet libraries
Arduino Bootloader to Flash from SD Card
Fronius Symo Hybrid battery charging/discharging limits setting with Modbus TCP
ESP8266 firmware to read and control EMS and Heatronic compatible equipment such as boilers, thermostats, solar modules and heat pumps
ESP8266 AT Firmware (Command Processor) With TLS 1.2 Capability
Ethernet Library for Arduino
DIY "SG Ready" adapter for Stiebel Eltron ISGweb. This Arduino sketch reads the state of digital input input pin of Arduino and sets the state over Modbus TCP to SG Ready INPUT1 register of ISGweb. It has overdeveloped monitoring and control.
A kitchen timer with clock.
Arduino Library Manager list
My Arduino boards custom variants. You can use it as starting point for your boards specialities.
Firmware for u-blox NINA W102 WiFi/BT module
Small and Fast Bootloader for Arduino and other Atmel AVR chips
The original Eclipse CVS Client plugin in exil
DIY Arduino consumption regulator build to use excess solar power for auxiliary 'summer' heating. The solar power data are retrieved over SunSpec Modbus TCP. IoT monitoring with Blynk and local Web server.
SD Update library for nRF5 Arduino
Arduino library to support Ethernet for STM32 based board
Arduino library with Stream helper classes. BufferedPrint stream for efficient networking. ChunkedPrint for HTTP chunked encoding. ChunkedStreamReader for HTTP chunked decoding. CStringBulder builds a c-string with Print class methods. StringReadStream to wrap string as Stream. And printf() function with formatting string from F macro.
A light 'alarm' clock designed for gentle wake-up with increasing light intensity.
Arduino Stream implementation over Telnet for OTA logging and debugging
