pcf8591同时采集两个模拟,数据是被调换过的
这是为什么呢?
老哥儿,还有问题哦
unsigned char Read_Ds1302_Byte ( unsigned char address )
{
unsigned char i,temp=0x00,dat1,dat2;
RST=0; nop();
SCK=0; nop();
RST=1; nop();
Write_Ds1302(address);
for (i=0;i<8;i++)
{
SCK=0;
temp>>=1;
if(SDA)
temp|=0x80;
SCK=1;
}
RST=0; nop();
RST=0; nop();
SCK=0; nop();
SCK=1; nop();
SDA=0; nop();
SDA=1; nop();
return (temp);
}
这是蓝桥杯给的ds1302的驱动,为什么这一步中temp是10进制的(因为给芯片传入的就是十六进制,不知道为啥到这一步突然变成10进制了)写的时候数据一直有问题,研究半天发现这一步的时候数据已经被处理为10进制了,但是我不知道为什么。
