eCxx is a library for AVR and NodeMCU tailored for micro LED displays and lighting effects.

eCxx is utilizing Makefile build system. Java and Python based applications/tools are also included to ease the development and debugging process using the host PC.

On one side, eCxx supports the original megaAVR series (ATmega328P, ATmega1284P, ATmega2560, ATmega32U4, AT90USB1286, etc.) as well as the new megaAVR 0-Series (ATmega4808, ATmega4809, etc.).

On the other side, while eCxx is primarily designed to work in NodeMCU, it should also support other ESP-12 based design as well as ESP-01 based design.

The Makefile build system and some of the tools would only run on Linux. However, the library source code should be portable enough to be built using other build systems for AVR and NodeMCU.

eCxx also comes with some open hardware design (schematics and PCBs) as well as some related test applications and firmware.


  • Tailored for micro LED displays and lighting effects.
  • Some Python and Java based utilities/tools to help with development and debugging.
  • Open Hardware schematic and PCB designs with some ready to use firmware.
  • Utility templates and template functions similar to C++11 (with slightly different name).
  • UniquePtr, SharedPtr, WeakPtr, NumericLimits, and FunctionTraits classes.
  • RingBuffer, Array, String, FixedPoint, and Dec24FP classes.
  • Conversion utility for strings and numbers with simple numeric-punctuation support.
  • Math utility functions.
  • Color space utility functions and color effect classes (including a simple painter).
  • Color animator classes (with their ready-to-use animation processor classes).
  • Utility classes to process IP and MAC addresses as well as UUIDs in string forms.
  • Utility functions related to byte order and C-locale.
  • Output formatter classes and their related utility functions.
  • Static application class with UART, SPI, TWIMaster, TWISlave, and OWIMaster support.
  • A one-wire, half-duplex, software UART for low and medium speed transmission.
  • Data-stream sampler for very low speed transmission.
  • Non-volatile data storage (available/usable capacity depends on the platform).
  • Multiple switch debouncing methods.
  • Keypad scanner that supports reading multiple key press (depending on the hardware).
  • Keypad debouncing that supports modifier key(s) and multiple key presses.
  • A simple reader class for two-axis analog joystick with one switch (push button).
  • A simple incremental (quadrature) rotary encoder reader class.
  • Character LCD driver supporting 4-bit parallel, UART, and TWI output modes.
  • Memory card reader and writer class (raw mode).
  • A simple slot-based file system.
  • BCM (binary code modulation) waveform generator.
  • Drivers for LED strip, LED matrix, DMX512 LED, and LED/OLED display.
  • Drivers for EEPROM.
  • Drivers for ADC, DAC, and other sensors.
  • Drivers for ethernet chips/modules.
  • Drivers for WiFi modules.
  • Drivers for RTCs.
  • Hardware information provider class.
  • Template text processor.
  • Lightweight web server.
  • A simple lighting visualizer system.
  • [x86 Only] Simulation data file generators for 1-dimensional and 2-dimensional LED simulation.
  • [x86 Only] A simple BMP file writer.
  • [AVR and AVRX Only] Analog comparator support.
  • [AVR and AVRX Only] Measurement of internal bandgap/reference voltage and temperature.
  • [AVRX Only] Additional timers/counters.
  • [AVRX Only] Real-time counter support.
  • [AVRX Only] Power-down and wake-up support.
  • [AVRX Only] Event system support.
  • [AVRX Only] Configurable custom logic support.
  • [NodeMCU Only] OTA programming support.
  • [NodeMCU Only] DMA (I2S) support (output-only).
  • [NodeMCU Only] TCP client and server.
  • [NodeMCU Only] TCP console (can be used for debugging without connecting to a physical serial port).
  • [NodeMCU Only] Web server and SSL web server.
