目前个人测试过AT24C02-AT24C128，感觉还可以。里面没有页写函数，有兴趣的伙伴可以补充一下，该程序仅供参考
单片机源程序如下:
- #include "led.h"
- #include "delay.h"
- #include "sys.h"
- #include "usart.h"
- #include "key.h"
- #include "24cxx.h"
- #include "myiic.h"
- //要写入到24c128的字符串数组
- const u8 TEXT_Buffer[]={"STM32 AT24c128"};
- #define SIZE sizeof(TEXT_Buffer)
- #define ADDRESS 163 //读写地址
- int main(void)
- {
-
-
- u32 fan,fan1=6553;
-
- u8 datatemp[SIZE];
-
- NVIC_Configuration();
- delay_init(); //延时函数初始化
- uart_init(9600); //串口初始化为9600
- LED_Init(); //初始化与LED连接的硬件接口
- KEY_Init(); //按键初始化
- AT24CXX_Init(); //IIC初始化
- while(AT24CXX_Check())//检测不到24c128
- {
- delay_ms(500);
- LED0=!LED0;//DS0闪烁
- }
- while(1)
- {
- //每一个函数都已经测试过，适合AT24C02-AT24C128
- //AT24CXX_WriteOneByte(2049,fan1);
- //AT24Cxx_WriteTwoByte(16383,fan1);
- //AT24CXX_Write(ADDRESS,(u8*)TEXT_Buffer,SIZE);
- //printf("Write:%s\r\n",TEXT_Buffer); //显示写入内容
- AT24CXX_WriteLenByte(0,fan1,2);
- delay_ms(1000);
-
- //fan=AT24CXX_ReadOneByte(2049);
- //fan=AT24Cxx_ReadTwoByte(16383);
- //AT24CXX_Read(ADDRESS,datatemp,SIZE);
- //printf("Read:%s\r\n",datatemp);//显示读取内容
- fan=AT24CXX_ReadLenByte(0,2);
- printf("Read:%d\r\n",fan);
- }
- }
