是一个基于AT91RM9200的Linux文件系统二进制代码，与刚才的内核代码一起使用！-is one based on the AT91RM9200 Linux file system binary code, and just the kernel code used together!

开发环境为uClinux2.4.x+s3c44b0。此程序以字节方式对IIC器件进行读写。通过硬件测试，可以直接使用。附：IIC测试程序。具体使用说明见其中的readme.txt。-development environment for uClinux2.4.x s3c44b0. This procedure in byte pairs IIC device reading and writing. Through hardware testing can be used directly. Report : IIC test. Specific use see the readme.txt.

The objective is to set up SPI communication between VTI Technologies digital pressure sensor component and an MCU of an application device ATMEGA16L. In this code example: ?The MCU is configured ?SCP1000-D01 is initialized and configured ?The high resolution measurement mode is activated ?Temperature and pressure information is read always when the DRDY pin is in high state Please refer to the document "SCP1000 Product Family Specification 8260800" for further information on SCP1000 register addressing and SPI communication.
