9260 EVC延時(shí)怎么精確到1us? 好像IO.h里有一個(gè)EM9260_DelayInUs（）函數(shù)，但是用起來(lái)與lcd_api.h沖突。

EM9260_DelayInUs（）怎么可能與LCD_API沖突呢？請(qǐng)具體一點(diǎn)，以便我們這邊也測(cè)試，謝謝！
us級(jí)的延時(shí)，延時(shí)的線程由于時(shí)間太短，所以是不可能釋放CPU資源的。對(duì)幾u(yù)s的延時(shí)，可以試試Sleep(0)，大概是5us - 6us。 我們提供的EM9260_DelayInUs（）是以u(píng)s為單位的。 |

我用了LCD_API.h EM9260_DIO_EX.h。運(yùn)行正常
我想用EM9260_DelayInUs（）的時(shí)候，在頭文件加上em9260_isa_dio.h。編譯就會(huì)出現(xiàn)說(shuō)em9260_isa.dio.h中的子函數(shù)已經(jīng)在lcd_api.lib中defined了。如下： //==================================================== Compiling...

我們馬上測(cè)試一下，然后答復(fù)。

測(cè)試了,包含了你所需要的三個(gè)文件,能正常編譯通過(guò),建議你重新從我們公司網(wǎng)上下載一個(gè)SDK包更新一下試試.或者將你的工程文件發(fā)過(guò)來(lái)我們?cè)囈辉?
