基于单片机的全彩OLED静态显示驱动接口电路

摘要

针对奇晶公司生产的CMEL CO283QGLD-T型OLED显示模块的特性,以宏晶科技的STC 11L60XE单片机为主控制器,进行OLED显示模块与单片机在SPI模式下的硬件接口设计和软件设计,并实现了分辨率为240×320的全彩图片静态显示.所设计的OLED驱动电路具有通用性,且可显示多种测试图片用于中小尺寸OLED的显示性能测试和评定.%An all-purposed full-color OLED driver circuit system is designed for the OLED module CMEL CO283QGLD-T based on the single-chip STC11L60XE of macro crystal. The principle of CMEL CO283QGLD-T is analyzed, the design of hardware and software between STC11L60XE and S6E63D6 is showed during SPI mode of S6E63D6, and the picture of 240x 320 resolution and 65 k color is showed. It is a common set of driving circuit for small and medium size OLED, it can display a variety of test images for small and medium size OLED display performance testing and evaluation.
