大家都知道EEPOM FL是有擦写寿命的
平时我们的单片机总是会用到其中一小部分 若是这一小部分都擦写到死 那么就会造成机器使用寿命的衰减 我就琢磨能不能平衡擦写或者有序擦写EEPOM中的每一部分 下面的代码解决了我的疑问 void EEPOM_Test_AddrChange(void) { u8 i=0; u8 j=0; Address_Channel_1= ORE_Resistance_Address_Channel_1; Address_Channel_2=STORE_Resistance_Address_Channel_2; Address_Channel_3=STORE_Resistance_Address_Channel_3; DE CT_Address=STORE_RT_DETECT_Address; TEMPER_Address=STORE_RT_TEMPER_Address;//定义了五个存储地址 i = (u8)AD_Get_Average(AD_CHANNEL_0); //A 采集值做随机数 while(1) { EE24c02_transfer(WRITE,Address_Channel_1,&i,1);//写随机数 EE24c02_transfer(READ,Address_Channel_1,&j,1);//读随机数 if(i==j)//E2POM没问题 { #ifdef DEBUG SERIAL_Putchar(Address_Channel_1);//如果读写正确 证明此字节擦写正常 #endif break;//跳出循环 } else { #ifdef DEBUG SERIAL_Putchar(Address_Channel_1); SERIAL_Putchar(i); SERIAL_Putchar(j); #endif Address_Channel_1 += 0x14;//如果擦写不正常 地址+20做为新地址 } } i = (u8)AD_Get_Average(AD_CHANNEL_0); //产生0-127的随机数 while(1) { EE24c02_transfer(WRITE,Address_Channel_2,&i,1); EE24c02_transfer(READ,Address_Channel_2,&j,1); if(i==j)//E2POM没问题 { #ifdef DEBUG SERIAL_Putchar(Address_Channel_2); #endif break; } else { #ifdef DEBUG SERIAL_Putchar(Address_Channel_2); #endif Address_Channel_2 += 0x14; } } i = (u8)AD_Get_Average(AD_CHANNEL_0); //产生0-127的随机数 while(1) { EE24c02_transfer(WRITE,Address_Channel_3,&i,1); EE24c02_transfer(READ,Address_Channel_3,&j,1); if(i==j)//E2POM没问题 { #ifdef DEBUG SERIAL_Putchar(Address_Channel_3); #endif break; } else { #ifdef DEBUG SERIAL_Putchar(Address_Channel_3); #endif Address_Channel_3 += 0x14; } } i = (u8)AD_Get_Average(AD_CHANNEL_0);//产生0-127的随机数 while(1) { EE24c02_transfer(WRITE,DETECT_Address,&i,1); EE24c02_transfer(READ,DETECT_Address,&j,1); if(i==j)//E2POM没问题 { #ifdef DEBUG SERIAL_Putchar(DETECT_Address); #endif break; } else { #ifdef DEBUG SERIAL_Putchar(DETECT_Address); #endif DETECT_Address += 0x14; } } i = (u8)AD_Get_Average(AD_CHANNEL_0); //产生0-127的随机数 while(1) { EE24c02_transfer(WRITE,TEMPER_Address,&i,1); EE24c02_transfer(READ,TEMPER_Address,&j,1); if(i==j)//E2POM没问题 { #ifdef DEBUG SERIAL_Putchar(TEMPER_Address); #endif break; } else { #ifdef DEBUG SERIAL_Putchar(TEMPER_Address); #endif TEMPER_Address += 0x14; } } } -电子元器件采购网（www.ruidan.com）是本土元器件目录分销商，采用“小批量、现货、样品”销售模式，致力于满足客户多型号、高质量、快速交付的采购需求。 自建高效智能仓储，拥有自营库存超过50,000种，提供一站式正品现货采购、个性化解决方案、选型替代等多元化服务。
