At end of i2c_start SDA is cleared
and you can see in my I2C_READ routine
i don't use SETB SDA,
therefore when i want to reading from SDA pin
SDA is 0,Why?
why my code works properly!
I accept my corection post was wrong
but jan,your attitude was unsuitable too
Please say your suggestion more friendly,etc.etc
