請問 我用Timer3作為PWM Clock的來源 去產生一個9600*16Hz的輸出,工作週期50% 無法正常輸出!!! 但是當我把Clock的來源設成Timer2時,就正常了 也試過其他的Tiemr(除了Timer2),就是無法正常輸出
因為我現在要兩個PWM輸出 且輸出的頻率不同 請問如何解決?!
我用的是PIC24FJ128GA108,Rev 0x1
註:產生的Clock是用來作為外接IrDA Encoder/Decoder Clock用的,在108內無法設定UEN來輸出16xBCLK,但是106可以...囧
謝謝 //--------------------------------------------------------- 以下是程式: static void _section(".oc5") vOC5Init() { mIO_UNLOCK(); RPOR1bits.RP2R=22; mIO_LOCK(); OC5CON1=0x0000; //OC5CON2=0x0000;
OC5CON1bits.OCTSEL = 0b001; OC5R =FCY/9600/16/2; OC5RS = FCY/9600/16/2; OC5CON1bits.OCM = 0x0006; IPC10bits.OC5IP0 = 1; IPC10bits.OC5IP1 = 0; IPC10bits.OC5IP2 = 0; IFS2bits.OC5IF = 0; IEC2bits.OC5IE =0; //--------------------------- T3CONbits.TON=0;
T3CONbits.TCS=0;
T3CONbits.TCKPS=0; PR3=FCY/9600/16;
IFS0bits.T3IF=0; IEC0bits.T3IE=0; T3CONbits.TON=1; } //--------------------------------------------------------- int _section(".main") main(void) { vOC2Init(); while(1); }
