不好意思後面CONFIG有修改如下:
config1 = (PWM_EN & PWM_IDLE_STOP & PWM_OP_SCALE16 & PWM_IPCLK_SCALE16 & PWM_MOD_FREE & PWM_POUT_1H & PWM_POUT_2H & PWM_GEN_1H & PWM_GEN_2H & PWM_GEN_1L & PWM_GEN_2L & PWM_POUT_1H & PWM_POUT_1L & PWM_POUT_2H & PWM_POUT_2L & PWM_POUT1L_INACT & PWM_POUT1L_ACT & PWM_POUT2L_INACT & PWM_POUT2L_ACT ); config2 = (PWM_MOD1_IND & PWM_MOD2_IND & PWM_MOD3_IND & PWM_PEN3H & PWM_PEN2H & PWM_PEN1H & PWM_PEN3L & PWM_PEN2L & PWM_PEN1L ); config3 = (PWM_POUT1L_INACT & PWM_POUT1H_INACT & PWM_POUT2L_INACT & PWM_POUT2H_INACT & PWM_SEVOPS1 & PWM_OSYNC_PWM & PWM_UEN); OpenMCPWM(PWM_Period,sptime,config1,config2,config3); 有大大知道小弟哪邊有錯的請不吝指教，謝謝您!!!

版主大大您好，我想寫3組PWM的訊號在同一個週期內不一樣的導通時間，也就是PWM輸出改寫的功能，以下為我的部份程式:
PWM_Period = 0x0170 ; PDC1=0x0170; PDC2=0x0170; OVDCON=0x0023; sptime = 0x0; config1 = (PWM_EN & PWM_IDLE_STOP & PWM_OP_SCALE16 & PWM_IPCLK_SCALE16 &PWM_MOD_UPDN); config2 = (PWM_MOD1_COMP & PWM_MOD2_COMP & PWM_MOD3_COMP & PWM_PEN3H & PWM_PEN2H & PWM_PEN1H & PWM_PEN3L & PWM_PEN2L & PWM_PEN1L); config3 = (PWM_SEVOPS1 & PWM_OSYNC_PWM & PWM_UEN); OpenMCPWM(PWM_Period,sptime,config1,config2,config3); } 我的問題是我看WATCH暫存器位址OVDCN也有改成我要的數字，我看操作手冊上有6種狀態(簡體中文版的15-30業)，請問要如何改??我的程式部份是否有誤??謝謝您~~ Attach file:  (0.00 KB)
