Channel3 is an experimental ESP8266 project that generates analog television signals directly from a microcontroller GPIO pin. It uses the ESP8266 I2S peripheral at an 80 MHz bit rate and DMA buffers to synthesize radio-frequency waveforms. An antenna connected to the output can transmit a signal receivable by an analog television tuned to Channel 3. The implementation produces luma and color information through carefully constructed one-bit modulation patterns. Several demonstration screens show text, graphics, color swatches, lines, and simple 3D scenes. ...

An Arduino NeoPixel support library supports a large variety of individually addressable LEDs. Please refer to the Wiki for more details. Please use the gitter channel to ask questions as the GitHub Issues feature is used for bug tracking. A library to control one wire protocol RGB and RGBW LEDs like APA106, SK6812, WS2811, WS2812, and WS2813 that are commonly referred to as NeoPixels and two-wire protocol RGB like Lpd8806, APA102, and SK9822 commonly referred to as DotStars. Supports most...

...The library is targeted at 32-bit processors, it has been performance-optimized for STM32, ESP8266 and ESP32 types. The library can be loaded using the Arduino IDE's Library Manager. Direct Memory Access (DMA) can be used with the ESP32, RP2040, and STM32 processors to improve rendering performance. "Four wire" SPI and 8 bit parallel interfaces are supported. Due to the lack of GPIO pins, the 8-bit parallel interface is NOT supported on the ESP8266. 8 bit parallel interface TFTs (e.g. UNO format mcufriend shields) can use with the STM32 Nucleo 64/144 range or the UNO format ESP32. ...

NOTE: This project is marked with 'Status: Abandoned' on SourceForge because not enough time can be dedicated to this project. However it may still get sporadic commits to the repository. 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...

...This library is intended to help the person programming the SPUs on the Cell processor move data into and out of the local store of an SPU without having to directly program the DMA hardware.
