s3c2440从AIN0读取外部直流电压V1，V1为放大100倍的整形值（使用可参考adc_test.c），外部电路图压降比6：1即V1取值范围V1=（0，3.3）*6-adc

at91sam9260的linux的ADC驱动，8位精度，可以修改成10位模式，AIN0--AIN3,四通道输入。应外附上测试程序，方便调试。-at91sam9260 of linux the ADC driver, 8-bit precision, can be modified into a 10-bit mode, AIN0- AIN3, four-channel input. Outside the testing procedure should be attached to faci

mini2440裸机，修改部分程序使之成为采集AIN1通道，从而避免占据AIN0通道。-The mini2440 bare metal, modify part of the program of to become acquisition AIN1 channel, thereby avoid occupy AIN0 channel.
