不曉得因為沒有寫usb的中斷副程式所造成,還是其它原因 因為下面的code有去進行修改為usbip為最低 且sspip為最高的優先權
但仍無法連續正常讀取 能否請各位大大幫忙解答 void UserInit(void) { unsigned char test[2]; PIE1 = 0 ; PIE2 = 0 ; IPR1 = 0; IPR2 = 0;
// Initialization for Interrpts !!
RCONbits.IPEN = 1 ; //Enable Priority interrupt type !!
IPR2bits.USBIP = 1 ; //Set USBIF as Low priority interrupt IPR1bits.SSPIP =0 ; //Set SSPIF as High priority interrupt
mInitAllLEDs(); mInitAllSwitches(); old_sw2 = sw2; old_sw3 = sw3;
TRISBbits.TRISB4 = 1 ; TRISBbits.TRISB5 = 1 ; TRISDbits.TRISD7 = 0 ; LED8 = 0 ;
ADCON0 = 0x01 ; ADCON2 = 0x25 ; ADCON1 &= 0xFE; // Only AN0 as Analog input ! ADCON0bits.GO = 1 ;
buffer[0]=0; buffer[1]=0; buffer[2]=0; buffer[3]=0;
emulate_mode = TRUE;
Initialize_I2C_Master(); //新增加的函數 }//end UserInit
//按sw3後就進行mssp的read..但此時就會造成當機 //--------------------------------------------------------------------- void ProcessIO(void) { unsigned char test[8]; BlinkUSBStatus(); if(!SW3){ if(flag_one==0){ LDByteReadI2C(0x16,0x0d,test[0],2); Delay100TCYx(10); mLED_3_On(); flag_one=1; } }
// User Application USB tasks if((usb_device_state < CONFIGURED_STATE)||(UCONbits.SUSPND==1)) return; Emulate_IO(); }//end ProcessIO
