Re: Implicit declaration of function 2019/03/07 02:07:58 +1 (1) A quick read of the XC8 User Guide to see how to use __delay_ms would have told you that you must have a line your file to "define" the symbol "_XTAL_FREQ", so the compiler knows how long to make the delays.

A function in which the dependent variable, and independent variable (s) are not separated (isolated) on opposite sides of the equality are known as implicit function. Implicit declaration of the function is not allowed in C programming. Every function must be explicitly declared before it can be called. In C90, if a function is called without an explicit declaration, the compiler is going to complain about the implicit declaration. implicit declaration of function 'read' implicit declaration of function 'write' read and write functions are declared in unistd.h which we forgot to include in our code. If you omit the declaration, then you will probably get a "conflicting types" warning since the compiler declared it for you and may use a different prototype than what you use in your definition.
