基于前面关于瑞萨e ² studio开发软件的使用，以及工程测试基础，本文进一步探索实现硬件IIC OLED的文字和图片显示。 简单介绍IIC通信协议、OLED显示原理、SS1306驱动IC等。 IIC通信协议 IIC（Inter-Integrated Circuit）即集成电路总线。它是一种串行通信总线，使用多主从 ...

OLED屏是一种常见的显示屏，下面以0.96寸OLED模块为例，用IIC的DMA来实现OLED屏幕的刷新。 采用DMA方式不需要程序一个个字节发送，通过启动DMA自动完成整个屏幕的刷新，可以节约大量的CPU时间。 该屏幕分辨率为128x64，每个点占用1bit，于是整个显存占用128x64/8 ...

Small I2C OLED displays are common nowadays, and thanks to the work of helpful developers, there are also a variety of graphics libraries for using them. Most of them work by using a RAM buffer, which ...

[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 ...

Developer Paolo Bernardi has taken to Kickstarter this month to bring his new my-ssd1306 hardware to market. The new board takes the form of an HTML interface to SSD1306 OLED display and is now ...
