摘　　要：将低成本的时钟语音芯片融入到嵌入式Linux系统中,不但可以丰富嵌入式设备的功能,而且可以降低开发成本。本文以ARM架构芯片S3C2440结合Linux2.6.22内核作为实例,开发出语音报时芯片YF017的驱动程序,并写出该驱动程序的上层应用程序。测试结果表明,通过上层应用程序可以准确地调用驱动程序,并使语音芯片发出相应的语音。Taking the low cost voice chip into the embedded Linux system,it is not only can enrich the function of embedded system, but also can reduce the cost of development. This paper develops the voice chip YF107 driver and the upper application program,using ARM chip S3C2440 with Linux2. 6. 22 kernel as an example. The test results shows that the program can accurately call the driver through the upper application, and the voice chip can send out the corresponding voice.
