TPM1通道2。。。請(qǐng)教各位看看中斷程序?qū)幔?br>在PRM文件中我設(shè)置： VECTOR 7 PWMCH2_ISR |

是進(jìn)不了中斷還是進(jìn)去了出不來(lái)？ 我看是出不來(lái)。中斷標(biāo)志CHnF的清除方法是這樣的：在CHnF=1時(shí)，首先讀TPMxCnSC，然后向CHnF位寫0。 所以進(jìn)入中斷后，應(yīng)該這樣來(lái)清除CHnF: interrupt void PWMCH2_ISR(void) { unsigned CHAR tmp; tmp = TPM1C2SC; TPM1C2SC&=0x7F; // ........ 否則，CHnF一直為LOGIC 1，退出中斷后馬上又進(jìn)來(lái)了。 |
