CodePudding user response:

AT24C02Read defined as two parameters, and use it every time it is a parameter

CodePudding user response:

That there should be how to change ah, thank you

CodePudding user response:

refer to the second floor Augustus, Dallas, Anton response:

here how to change the world, thank you

You declare the function is
Unsigned char At24C02Read (uchar addr, uchar num)
Call is At24C02Read (addr)

You need to change the function declaration, such as
Unsigned char At24C02Read (uchar addr)
{
Uchar num.
