Writing structures of language C in general is consisted of 4 blocks:
1. Header.
2. Constanta declaration global and or variable.
3. Function and or procedure (this can be written under principal program).
4. Principal program.
In general, programming C was simplest programming to be done with only writes down main program only, that is:
Void main (void)
{
….
}
The full programming done is:
/*HEADER for call library that will used*/
#include
#include
/*Constanta declaration and or global variable */
Unsigned char dt, xx;
Char buf[33];
/* Function declaration and or procedure */
Unsigned char lamp (unsigned char bitn)
{
PORTA=bitn & 0x3C;
}
/*Main program */
Void main (void);
/* Constanta declaration and or local variable */
Char data;
PORTA=0x00;
DDRA=0xF0;
While (1)
{
…
};
}
