摘要
S3C44B0X作为一款以ARM7TDMI为内核的微处理器,得到广泛的应用,uClinux作为一种运行于没有MMU的嵌入式微处理器的操作系统,也广泛应用到嵌入式开发中。本文首先分析了S3C44B0X的ADC转换器的特点,详细分析了uClinux的设备驱动机制,并论述uClinux的设备驱动的处理过程,应用实例介绍了基于S3C44B0X的ADC转换器的设备驱动程序,以及在uClinux下静态加载设备驱动程序的过程。
S3C44B0X microprocessor with a core of ARM7TDMI is widely used.uClinux running on embedded microprocessor without MMU is also used in embedded design.The characteristic of ADC converter of S3C44B0X is analyzed in this paper.The device driver mechanism of uClinux is analyzed detailedly,and the treatment process of the device driver of uClinux is discussed.The device driver programming of ADC converter of S3C44B0X is introduced through an example.At last the loading process of device driver under uClinux is given.
