基于SPI的OLED显示技术
The Display Technology of OLED Based on SPI
摘要
针对OLED模块应用中8位数据并行接口占用单片机I／O 管脚较多的问题，本文介绍了SPI总线接口在OLED模块中的应用。并以VGG12864L-S002显示模块为例，进行了相应的硬件、软件设计。在实际应用中，采用SPI方式达到了并行接口方式的效果，同时简化了电路设计，节约了I／O 管脚。
Abstract
To resolve the problem that 8-bit data parallel interface ties up much more I／O pins of microcomputer during the application of OLED module，this paper introduces the application of SPI，and do some correlative design of hardware and software with VGG12864L-S002．In actuaI application．it shows that the SPI mode comes to the effect of parallel interface predigesting the design of circuit and saving the I／O pins．
