本帖子已过去太久远了，不再提供回复功能。在做有AD模块项目的时候遇到几个问题：
1，& ADC配合DMA采样规则是怎样的。
2，& ADC在DMA采可否不连续采样，以提高有效采样使用率和降低功耗。
3，& 如何提高有效利用率和降低功耗，并减少CPU的占用时间。
4，& ADC的如何多通道采样。
针对以上几个问题做解答。
ADC的采样模式主要分两个：规则采样和注入采样。规则模式可采样16个通道，注入模式最多只能4个通道。
配合DMA使用时主要是用规则采样模式。在初始化时配置采样端口为规则采样通道即可如下：
列：&&&&&&&& ADC_RegularChannelConfig(ADC1, ADC_Channel_0, 1, ADC_SampleTime_239Cycles5);&
端口1为规则采样的第一位，239.5的ADC时钟采样周期。
&&&&&&&& ADC在DMA下可以不连续采样，既采样一定数据后，关闭ADC及DMA通道。但是这样子存在一些问题。DMA的存储的变量数组中的数据会出现错位问题。
测试过很多方法，包括ADC和DMA一起重新初始化，依然无法解决这个问题。系统只进行一次初始化时，DMA数据无错位现象。 但是对于长时间不关机的产品来说，缺少了几分可靠性。网上也有相关的评测，ADC用DMA工作在强电磁的环境中可能会输出丢失部分数据的可能。
&&&&&&&& 这里就想到了用中断的方式，进行采样。无法用规则模式，因为只能用单次采样触发中断。由于无法确定第一个通道，这样同样会遇到数据错位的现象。所以这里使用注入模式进行中断出发。
有以下几个优点：
1，& 可以最多4路为一组采样，每组采样结束后才产生一次中断，减少了进中断的次数。
2，& 在读取数据时几路通道都是预先配置好的。某个变量存放指定某个指定通道。这样永远不可能出现错位现象。
由以总结 在4路及以下通道进行采样时，首选注入模式进行中断采样。超过4路及不是长时间工作的产品（几天以上不断电）可以考虑。
单路采样时，这两种方法都很可靠。
&&&&&&&& 最近刚好在学习uCosII系统，并参考了下通用驱动程序开发。附上ADC驱动代码，希望有所帮助。
　　提示，在使用某路通道 只要 该通道宏定义置1就可以了。
#define ADCx_CHANNEL0_EN
1 //ADCx通道1
1:便能，0:失能
注意： 在使用注入模式时 最多使能4个通道。
