摘要
介绍了OLED显示模块的特点及其在ARM核处理器S3C4510B和uClinux嵌入式操作系统下的应用,给出了系统的硬件电路设计。根据OLED模块指令集特点,在uClinux下采用对OLED模块编写用户空间设备驱动程序的方法,实现了终端对OLED的控制。实验表明,采用用户空间驱动程序可以减小操作系统开销、提高系统对外设的响应速度。
This paper introduces the characters of OLED display module and the applications of it based on S3C4510B and uClinux and gives the design of the system hardware circuit. According to the characters of the OLED module instructions collection, the control over OLED is realized through the method about how to drive OLED display module in uClinux embedded operating system with a device driver in the user space. The experiments show that the driver program with user space can decrease the cost of operating system and improve the response speed to the terminal
