| IoAbstraction | Treat PCF8574, MCP23017 and Shift registers like pins, matrix keypad, touch screen handler, button press and rotary encoder management (switches) on any supported IO (including DfRobot & Joysticks) with event handling, interchangable AVR/I2C(AT24) EEPROMs. |
| LiquidCrystalIO | LiquidCrystal fork for displays based on HD44780. Uses the IOAbstraction library to work with i2c, PCF8574, MCP23017, Shift registers, Arduino pins and ports interchangably. |
| SimpleCollections | An associative container used either as a list or btree without needing std lib, and a concurrent circular buffer. Works from AVR/Uno upwards to ESP32, mbed etc |
| TaskManagerIO | Task manager for Arduino and mbed with marshalled interrupts, first class support for events and timed execution. Thread safe for RTOS use. |
| tcMenu | An IoT ready, modular menu solution that supports many input and display devices with a full designer UI and strong remote control capability. |
