![]() ![]() Note, that the LED panel topology and the display width/height can currently not be changed in the web interface. Verify that the LED panel topology is correct and you see the "Hello World" on the display.Upload/Update the software and firmware to the target.Build the software and check whether the toolchain works.Once it runs, later on the firmware and filesystem can be updated via the PIXELIX web interface. The following steps are necessary for the first time and to get PIXELIX initial running on the target. Digitial microphone INMP441 for some sound reactive stuff.LILYGO® T-Display ESP32-S3 1.9 inch ST7789 LCD Display Touch Screen Development BoardĪlthough PIXELIX was designed to show information, that is pushed or pulled via REST API, the following sensors can be directly connected and evaluated:.LILYGO® TTGO T-Display ESP32 WiFi and Bluetooth Module Development Board For Arduino 1.14 Inch LCD.Special VariantsĪdditional supported variants, which were original not in focus: Also recommended is to use a esp32 dual core variant, which provides more processing power. 4 MB flash modules are still supported, but the functionality is limited. If you assemble your own Pixelix hardware, its recommended to use a development board with 8 MB flash or more. With the Ulanzi TC001 smart pixel clock you even don't need to assemble the electronic and mechanic together. In the meantime several other boards are supported as well. ℹ️ To avoid any damage on your hardware and by the way to your eyes -), PIXELIX starts up with a low brightness setting. Please use a external power supply with at least 5V / 4A. Avoid increasing the LED display brightness or filling it complete with white pixels. ⚠️ If you power the development board and the LED matrix via USB: Be very careful, because it may destroy your ESP32 board if the LED current is too high. It may differ depended on your development board. The following shows the absolute minimal wiring setup e.g. WS2812B 5050 8x32 RGB Flexible LED Matrix Panel.The original setup for development and the first release was: See the config.ini configuration files in. ![]() for MQTT support you need 8 a development board with 8 MB flash or more. Please note, that not every feature might be available for all kind of development boards. Can be extended with custom effects and animations.Supports REST API and MQTT for remote control and integration with other systems, like Home Assistant.Includes a web interface for configuring and controlling the LED matrix.Can display static or scrolling text, as well as static or animated icons.Its possible to cascade another matrix to have a longer display. Supports 32x8 LED matrix size out of the box.It can be used to display text and animations. The PIXELIX firmware is for ESP32 boards that controls a RGB LED matrix. Can be connected to the local network via WiFi and controlled via REST API or Websocket. My initial goal was to have a remote display that would show multiple kind of information and run reliably 24/7. How to configure my own list of plugins?.Is it possible to use a font with 8px height?.Why do I see sometimes values from the LDR in the SensorPlugin, although no LDR is installed?.How do I know that my sensor is recognized?.The display only shows a error code, like "E4".Where to change panel topology of the LED matrix?. ![]()
