感謝R大的回覆
可是我目前用的dsPIC30F4011這顆晶片
計數器的Timer3
就會用到PR3

請問
PR3=0xFFFF;
代表計數時間為多少秒阿?
(外部頻率為FCY 7372800*2)

如題
我的ICD2每次開啟電源後
都會出現BUSY
後來程式BUILDING
就會如下
MPLAB ICD 2 Ready
ICD0060: Failed to bulk read target memory (Data) (Address:0x81E) (Size:0x2)
ICD0151: Failed to sync memory (MT = Data) (Dir = 0x0)
ICD0082: Failed MPLAB ICD 2 operation
ICD0082: Failed MPLAB ICD 2 operation
Resetting Target
ICD0082: Failed MPLAB ICD 2 operation
...Failed to reset target

請問這是什麼問題?
該如何解決?

PIC16F877 V.S PIC30F4011
16F877的程式語言寫法
和30F4011的寫法相同嗎?
還有哪些差異呢

#define __dsPIC30F4011__

#include <p30f4011.h>

#define FCY 7372800*2 //one instruction frequency
//constract initial
_FOSC(CSW_FSCM_OFF & XT_PLL8);
_FWDT(WDT_OFF);
_FBORPOR(0x008300); //enable MCLR, PWMPIN=1(controlled by port at device reset),HPOL=1 and LPOL=1 active high output polarity
_FGS(CODE_PROT_OFF);

int main(void)
{
ADPCFG=0xFFFF;

initial_PWM();

while(1);
}

void initial_PWM(void)
{
PTCONbits.PTEN=0; //base timer close
IFS2bits.PWMIF=0; //PWM interrupt flag clear
IFS2bits.FLTAIF=0; //PWM fault interrupt clear
IEC2bits.FLTAIE=0; //disable PWM interrupt
IEC2bits.PWMIE=0; //disable PWM fault

PTCONbits.PTSIDL=1; //PWM halt when idle mode
PTCONbits.PTOPS=0x0; //interrupt 1:1 postscale
PTCONbits.PTCKPS=0x0; //1:1 prescale
PTCONbits.PTMOD=0x0; //operating in a free running mode

PTPERbits.PTPER=0x024D; //PWM time base period register
PDC1=0x024D; //PWM1 50%
PDC2=0x024D; //PWM2 50%

PWMCON1bits.PMOD1=1; //independent PWM 1H 1L output mode
PWMCON1bits.PMOD2=1; //independent PWM 2H 2L output mode
PWMCON1bits.PEN1H=1; //PWM1H enabled for PWM output
PWMCON1bits.PEN1L=1; //PWM1L enabled for PWM output
PWMCON1bits.PEN2H=1; //PWM2H enabled for PWM output
PWMCON1bits.PEN2L=1; //PWM2L enabled for PWM output

PWMCON2bits.SEVOPS=0x0; //special event trigger 1:1 postscale
PWMCON2bits.OSYNC=1; //overrides synchronous PWM time base
PWMCON2bits.UDIS=0; //enable updata duty cycle
PTCONbits.PTEN=1; //base timer open
}


這是我目前的程式
我想控制無刷馬達
請問OVDCON要如何設定
(放在哪個程式段)
才能得到講義上的波形?
(應該是說如何產生截波)
講義我已經下載看過了
都說要在獨立輸出模式
可是試了很久都弄不出來
不知該如何設定
還是我的程式有錯?

學了不少...3Q

ICD2 Firmware　如何更新?
FAE是什麼阿?

我build完後，按燒入鍵時，出現下列文字
請問我的燒錄器怎麼了?
還是哪邊設定有問題?

小弟我目前正在寫用於無刷直流馬達的PWM
我試過OVDCON暫存器
也在設定了在獨立的PWM輸出
可是還是波形出不來
請教各位高手
教一下吧
如有範例程式最好
謝謝!
