標(biāo)題: 求助stc8051U 定時(shí)器t0不工作，pwm也沒工作
/*根據(jù)電池容量的mAh，可以計(jì)算電池的持續(xù)放電時(shí)間的電流數(shù)去確定電池的容量。
以下用了一個(gè)STC12C5608AD去做檢測(cè)電池放電400mA的時(shí)間，再以公式400mA*時(shí)間=mAh

運(yùn)行時(shí)間和檢測(cè)電壓都正常，就是PMW不正常無(wú)輸出，把ADC關(guān)掉PMW有輸出

這里的TL0,TH0改為TL1,TH1試試

還有這里的初始化，TL0,TH0改為TL1,TH1

TL0,TH0改為TL1,TH1，還是不行，
