S3C2440-AD应用

使用电位器模拟传感器，进行模数转化，将AD值转化为温度值，实时显示在LCD上。汉字使用48*48字模，字符使用24*48字模。通过软件PCtoLCD2002提取字模。这里主要用到ADCCON寄存器。首先要使能预分频器，因为太快会没转化完，所以降低频率，设置分频比，然后是选择模拟输入通道。然后启动AD转换，该位在开始后自动清零，通过ECFLG位检查是否转化结束。ADCDAT0低10位用来存放转化来的数据。

要做一个项目需要用到mini2440上的adc ，经查 发现其中的8个adc端口只能使用4个（只给了4个输入引脚AIN0，AIN1，AIN2，AIN3），其他的几个通道为触摸屏使用 我在使用adc时遇到的问题： 1.   因为之前没用过板上的GPIO，所以一开始不知道通道分别对应哪些管脚。我用了万用表测了下，如下图所示 2. 编写adc驱动 ，我参照了   http://showyo
