编译成功了,可是时间无法显示,我测试过了,其他模块没有问题,就是这个模块不知道哪错了。
void DS1302ByteWrite(unsigned char dat)
{
unsigned char mask;
for (mask=0x01; mask!=0; mask<<=1)
{
if ((mask&dat) != 0)
DS1302_IO = 1;
else
DS1302_IO = 0;
DS1302_CK = 1;
}
DS1302_IO = 1;
}
unsigned char DS1302ByteRead()
{
unsigned char mask;
unsigned char dat = 0;
for (mask=0x01; mask!=0; mask<<=1)
