想請教一下，以下是我的source code
#include <p18f452.h> #include "i2c.h" #define SW2 PORTAbits.RA4 void InitialPort(void); void Delay(unsigned int count); void main(void); unsigned char arraywr[] = {1,2,3,4,5,6,7,8,9}; unsigned char *wrptr = arraywr; unsigned char arrayrd[10]={0}; unsigned char *rdptr = arrayrd; unsigned char a,b,c; unsigned int aa; void main(void) { TRISAbits.TRISA4=1; // Set SW2 for input InitialPort() ; OpenI2C(MASTER,SLEW_ON); SSPADD= 9; while(1) { if(!SW2) { a = EEPageWrite(0xA0, 0x70, wrptr); b = EEAckPolling(0xA1); c = EESequentialRead(0xA0, 0x70, rdptr,15); aa = EERandomRead(0xA0, 0x30); } } } 這是單純把一陣列寫入eeprom，和讀出，可是小弟用watch觀 察讀出陣列，但都沒有寫入值，不知道寫入法式不對還是怎樣，我有參看版上提供的範例程式，但太複雜，所以就先以Microchip Reference Guide提供的example練習，但還是有問題。 感謝各位大大的回答…小弟感激不盡 m(_ _)m 剛學pic沒幾個禮拜，所以，請各位大大見諒
