9260 EVC延时怎么精确到1us? 好像IO.h里有一个EM9260_DelayInUs（）函数，但是用起来与lcd_api.h冲突。

EM9260_DelayInUs（）怎么可能与LCD_API冲突呢？请具体一点，以便我们这边也测试，谢谢！
us级的延时，延时的线程由于时间太短，所以是不可能释放CPU资源的。对几us的延时，可以试试Sleep(0)，大概是5us - 6us。 我们提供的EM9260_DelayInUs（）是以us为单位的。 |

我用了LCD_API.h EM9260_DIO_EX.h。运行正常
我想用EM9260_DelayInUs（）的时候，在头文件加上em9260_isa_dio.h。编译就会出现说em9260_isa.dio.h中的子函数已经在lcd_api.lib中defined了。如下： //==================================================== Compiling... LCD2.cpp Linking...

测试了,包含了你所需要的三个文件,能正常编译通过,建议你重新从我们公司网上下载一个SDK包更新一下试试.或者将你的工程文件发过来我们试一试.
