"Clean" implementation of Alex Guyver's FireLamp analogue in pure C for ESP32.

Display beautiful effects on a multiple matrices of NxN WS2812B/SK6812/APA106 LEDs.

• ~30 very beautiful effects from different authors, each with set of parameters
• WiFi connectivity in station or access point modes (support for DHCP/static IP addressing)
• JSON HTTP API for remote controlling
• Embedded webserver for remote controlling from browser
• TODO: OTA

You will need:

• ESP32 (ESP32 only! ESP32-S2/ESP32-C3/ESP32-C4 and others are not yet supported)
• One or more WS2812B/SK6812/APA106 LED matrices
• 4 buttons:
  • Main: long press - On/Off, click - next effect
  • Up/Down: brightness up/down
  • Reset: long press - Reset settings to defaults

The LEDs in the matrix are connected in series like a "snake", starting from the bottom row:

The sizes of the most common matrices:

• 8x8
• 8x32
• 16x16

To control one matrix, only one GPIO pin of the microcontroller is needed:

This configuration is the simplest supported. The dimensions of the matrix side are limited to the range 8..128.

You can connect up to 8 LED matrices of the same size to different GPIO pins and achieve high resolution rendering of the effect. For example:

Configure your LED layout at runtime by API or in browser ("Menu -> LEDs Settings"):

You can select GPIOs, set default WiFi config, LED layout and more in idf.py menuconfig (*** EvLamp configuration ***).

• Setup latest ESP-IDF master
• git clone https://github.com/UncleRus/EvLamp.git
• git submodule init --recursive --remote
• idf.py menuconfig
• idf.py build
• idf.py flash to upload firmware to ESP
