你一定沒有用 Microchip 的除錯工具來除錯吧! 這樣不是玩的很辛苦嗎?

已經找到問題了...
原來是Watchdog timer設定為Enable... 只要將Watchdog timer設定為Disenable即可...

dsP30F2010 OC模組輸出PWM訊號問題

我使用dsPIC30F2010 OC模組輸出PWM訊號時，當使用RS-232改變一次OC1RS值後，PWM訊號有出來，但是隔一段時間PWM訊號就會消失，需再次使用RS-232設定OC1RS的值，PWM訊號才會出來，不知道是程式哪裡有錯誤還是有暫存器沒有設定到，請大大幫忙看一下..
#include<p30F2010.h> #include <timer.h> #include <outcompare.h> int Duty,V,i; char uart; //---主程序-------------------------------- void main() { //----UART---- TRISFbits.TRISF2 = 1; TRISFbits.TRISF3 = 0; U1MODEbits.STSEL = 0; U1MODEbits.PDSEL = 0; U1MODEbits.ABAUD = 0; U1BRG = 12; U1MODEbits.UARTEN = 1; U1STA = 0x0400; //IEC0bits.U1RXIE = 1; //----DA---- PR2 = 1000; OC1R = 0; OC1RS = 0; OC1CON = 0x0006; ConfigIntTimer2( T2_INT_PRIOR_6 & T2_INT_OFF ) ; TMR2 = 0; PR2 = 1000; T2CON = 0x8000; T2CONbits.T32 = 0; CloseOC1(); ConfigIntOC1(OC_INT_OFF & OC_INT_PRIOR_7); OC1CONbits.OCM = 0; OC1RS = 0x0000; OC1R = 0x0000; OC1CON = 0x0006; while(1){ if(IFS0bits.U1RXIF){ Duty =U1RXREG; V = (Duty-48)*100; IFS0bits.U1RXIF = 0; OC1RS = V; } }
