沒辦法，PIC18F1220 只有 18 隻腳，I/O 功能有限你可以先用PIC18F4320 先行代用，或直接用 PIC16F716 取代 ECCP 功能。

你好!
如果是這樣那是否代表full bridge(P1C,P1D)PWM亦不能使用! 除非ICE2000來DEBUG? THANK you

如果妳是用 ICD2 除錯的話，那 RB6, RB7 就必需保留給 ICD2 用。

... CCP1CON = 0b00001100;//p1A=pwm ... ... .. PORTA = 0; TRISA = 0b00111111; // Set RA7 and RA6 asoutputs PORTB = 0; LATB = 0; ADCON1 = 0b11110000; // Configure AN0~AN3 as analog TRISB = 0b00110011; // Set RB7,RB6,RB3,RB2 outputs RBPU = 0; // RB=0,Are pull up resister //結果trisb=10110011
