code warrior 10.5 中使用processor expert _LDD疑问？

liu-391548

 code warrior 10.5 中使用processor expert 生成代码时，有一部分模块名以_LDD，例如DMA_LDD，请问带_LDD和不带LDD有什么区别？在使用上，有什么不同？

暂时我用下来 带LDD的类似库，并附带典型应用等。
蓝色小图标那种更偏向于手动修改寄存器。

最主要的区别是，带LDD的可以用于RTOS， 不带LDD的不可以。 kinetis系列的一般都支持带LDD的
这时从help里抓来的：

·         LDD components - Logical Device Drivers. The LDD components are efficient set of components that are ready to be used together with RTOS. They provide a unified hardware access across MCUs allowing to develop simpler and more portable RTOS drivers or bare board application. See chapter Logical Device Drivers for details.
