Description: Linux的射频模块驱动设计。 本文首先从嵌入式系统的概念、ARM微处理器和嵌入式操作系统的概念出发，描述了S3C2410的体系结构，具体研究了UART口和I/O口的控制，然后深入到linux环境下的驱动开发当中，介绍了本论文的软件开发环境，然后讨论了Linux系统驱动程序的程序构架，最后讨论了Linux驱动体系结构，重点叙述了字符型驱动程序的编写方法。然后完成了射频控制模块（ATMEL公司AT86RF211芯片）的驱动以及电路设计，通过S3C2410的UART口传输数据，通过I/O口去控制射频芯片。给出了驱动实现的关键程序和最小系统模块电路图。射频模块（AT86RF211）的驱动程序，包括了对它的模块收发数据的时序实现和对模块实体的控制。-The Linux radio frequency mold piece drive a design. This text set out from the concept, ARM microprocessor of the built-in system and the concept of the built-in operate system first, description the system structure of the S3 C2410, concrete research UART and I/O of control, then thorough arrive under the linux environment of drive a development in the middle, introduction the software of this thesis development environment, then discussion the Linux system drive the procedure frame of procedure, end discussion the Linux drive system structure, point describe character list type drive procedure of write a method.Then completion radio frequency control drive of mold piece(the ATMEL company AT86 RF211 chip) and electric circuit design, the UART which pass the S3 C2410 deliver a data and pass an I/O chip to the control radio frequency .Give drive the key procedure of realization and minimum system mold a piece electric circuit diagram.The radio frequency mold piece(the AT86 RF211) drive
