各位高手您好：
小弟想請問一下PIC30F4011之OC2要如何設定使其有PWM信號呢?? 以下為小弟設定OC1及TIMER2程式內容，是可以打出PWM的，但是小弟不會設定OC2的PWM訊號，請問一下我該如何設定呢，另外想請問一下，OC1的設定我使用TIMER2為其來源，若我要設定OC2的會，其實麥來源我是否需要另外設定一組TIMER，若需要則該選擇哪一組TIMER以及如何做TIMER的設定，拜託各位了!! OC1設定 void Init_OC1(void) { CloseOC1(); ConfigIntOC1(OC_INT_OFF & OC_INT_PRIOR_7); // IEC0bits.OC1IE = 0 ; // IFS0bits.OC1IF = 0 ; // IPC0bits.OC1IP = 7 ; OpenOC1(OC_IDLE_CON & OC_TIMER2_SRC & OC_PWM_FAULT_PIN_DISABLE, 0, 0); // OC1CON= 0x0006; } TIMER2設定 void Init_Timer2(void) { ConfigIntTimer2( T2_INT_PRIOR_6 & T2_INT_ON ) ; // Timer2 的中斷優先等級設 6 // Timer2 的中斷 OFF OpenTimer2( T2_ON & T2_IDLE_STOP & T2_GATE_OFF & // Timer2 的 Period 設為每 64ms T2_PS_1_1 & T2_32BIT_MODE_OFF & T2_SOURCE_INT, 1023) ; }
