摘　　要：针对小型OLED屏幕驱动和使用存在的问题,设计了一种通过串口控制的OLED屏幕驱动显示系统。该显示系统硬件由STC8F1K08S2处理器、小型OLED屏幕、外部FLASH存储器组成。STC8F1K08S2作为整个系统的控制核心,控制字库数据的读取、OLED屏幕的驱动、串口内部与外部数据的交换;软件上利用封装独立驱动函数模块,通过外部控制指令完成整个显示系统的控制。与传统的控制方法相比,更加方便快捷,节省处理器内部存储空间,可任意显示字符、汉字、图像等信息,支持3种尺寸的GB2312汉字显示,并且可外接蓝牙等无线串口设备实现无线显示驱动。实验结果表明,该显示系统运行稳定可靠,显示效果清晰流畅,可方便地被各种带有串口的处理器驱动,提高了小型OLED屏幕的适应性和应用范围。Aiming at the problems of small OLED screen driver and application, a kind of OLED screen driver display system controlled by serial port is designed. The hardware of the display system consists of STC8 F1 K08 S2 processor, small OLED screen and external FLASH memory. STC8 F1 K08 S2,as the control core of the whole system, controls the reading of font data, the driving of OLED screen, and the exchange of internal and external data of serial port. In software, it uses encapsulated independent driver function module to complete the control of the whole display system through external control instructions. Compared with the traditional control method, the system is more convenient and fast, saves the internal storage space of the processor, can display characters, Chinese characters, images and other information arbitrarily, support GB2312 Chinese character display of three sizes, and can connect Bluetooth and other wireless serial devices to realize wireless display driver. The experimental results show that the display system is stable and reliable, and the display effect is clear and smooth. It can be easily driven by various processors with serial port, which improves the adaptability and application range of small OLED screen.
