High Speed SSD1306 Library

[Lewin] wrote in to tell us about a high speed library for Arduino Due that he helped develop which allows interfacing OLED displays that use the SSD1306 display controller, using DMA routines for faster display refresh time. Typically, displays such as the Monochrome 1.3″ 128×64 OLED graphic display , are interfaced with an Arduino board via the SPI or I2C bus. The Adafruit_SSD1306 library written by [Limor Fried] makes it simple to use these displays with a variety of Arduinos, using either software or hardware SPI. With standard settings using hardware SPI, calls to display() take about 2ms on the …read more #Arduino, #ArduinoDUE, #ArduinoHacks, #DirectMemoryAccess, #Dma, #I2C, #ILI9341, #More, #Oled, #SAM3X8E, #Spi, #SPIH, #Ssd1306
