STM32模拟IIC读写24C02

糖豆豆 · 发表于 2015-11-2 15:07:06

菜鸟想用原子的程序实现float数据参数存入24C02，并读取实现调用，但是调试显示数据写入24C02但是读取不成功，请各位大神帮我看看哪有问题？
下面是我编写的一部分主程序
u8 L_M,t_p;
const float s = 7.0,t = 1.0;
const u8 TEXT_Buffer[]={s,t};
#define SIZE sizeof(TEXT_Buffer)

AT24CXX_Init();

while(AT24CXX_Check())
{
printf("\n 24C02 Check Failed! \n");
delay_ms(500);
printf("\n Please Check! \n");
}

while(1)
{
if(SIZE < 255)
AT24CXX_Write(0,(u8*)TEXT_Buffer,SIZE);
AT24CXX_Read(0,Parameter_Buffer1,SIZE);
L_M = AT24CXX_ReadLenByte(0,4);
t_p = AT24CXX_ReadLenByte(4,4);
printf("\n L= %f",L_M);
printf("\n t= %f",t_p);
}
