Based on ARM7-μCLinux and use hyperterminal to monitor two-way voltage parameters

This paper is committed to making a device for simultaneous measurement of two-way circuit voltage parameters.Based on embedded systems,using the uCLinux operating system and LPC2200 series development boards complete the function of this device.Using 10-bit A/D conversion precision,and the system uses the small capacity of the μCLinux kernel.Moreover,the way of kernel module is used to install a A/D device,it makes the kernel more condensed and makes applications run faster.The whole superiority exceeds the original SCM.First,compiled and transplanted μCLinux kernel and file system to the LPC2200 development board.Second,install a A/D device drivers by way of kernel module to connect underlying hardwares and the upper applications.The last,write applications program to read two-way voltage parameters,compile and copy to the development board to run.Obtained measurement results are accurate,real-time,effective.
