这个是我写的2440的SPI主从通信代码。

s3c2410,s3c2440,spi驱动查询模式-s3c2410, s3c2440, spi-driven spolling mode

linux的ad驱动，spi通信，而且是模拟spi通信，每5毫秒采集一次，一共采集10秒钟，平台是s3c2440+linux3.6.9-linux driver of the ad, spi communication, and simulation spi communication, collected once every 5 milliseconds, 10 seconds total acquisition platform is s3c2440+ linux3.6.9
