hey i have got a very simple solution……
just copy and paste the following statements(ANSI prototype)…….
lcdcmd(unsigned char value);
MSDelay(unsigned int value);
lcddata(unsigned char value);
but make sure that the function you have defined must include the contents of prototype statement.
example:
#include<reg51.h>
lcdcmd(unsigned char value);
MSDelay(unsigned int value);
lcddata(unsigned char value);
void main()
{
.
.
.
.
.
.
}
functions:
lcdcmd(unsigned char value);
{
rs=0;
rw=0;
en=1;
MSDelay(200);
en=0;
}
lcddata(unsigned char value);
{
…..
}
MSDelay(unsigned int value);
{
………….
}
