Create a routine that waits for a keypress and then call it.
Example:
| Code: |
#include <16F877.H>
#fuses XT, NOWDT, BROWNOUT, PUT, NOLVP
#use delay(clock=4000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, ERRORS)
#include "flex_lcd.c"
#include "flex_kbd.c"
// Wait for a key on the keypad to be pressed. Then return it.
char wait_kbd_getc(void)
{
char retval;
while(1)
{
retval = kbd_getc();
if(retval)
return(retval);
delay_ms(10);
}
}
//======================
void main()
{
char k;
lcd_init();
kbd_init();
while(1)
{
k = wait_kbd_getc(); // Wait for a key press
printf(lcd_putc, "\fKey = %c", k); // Display it on LCD
}
} |

| I know this shouldn't be happening but now I have to press the keys for quite some time, otherwise they aren't detected. And what about sending control commands to lcd. How can I do that? |

| Also please tell me can I call "wait_kbd_getc(void)" routine from some other routine? (other than main())? |

Get creative. Try reducing the debounce period. Reduce it from 10ms to 5ms. Experiment.

Don't ask my permission. Just try it. |

I have no idea where lines 32 and 117 are in your code. I am not a
mind reader. I suggest that you read the CCS manual and look at
the correct syntax for whatever lines are causing the problem. Also
look at the code for a few lines above the error line. Sometimes the
compiler generates an error in later lines, if you are missing a brace
or some other syntax error.
In other words, don't depend on me to solve your problems.
Learn how to trouble-shoot the problem by using your own mind. |

You cannot re-declare the function input().
How do expect the compiler to know what you mean here?

| I want to call the function input() and assign the value it returns to input variable. Is that ok? |

You are not allowed to assign anything to the function input().
You cannot name a variable with a reserved word such as the name of a
function. Change the name...

Ok. I changed the name of function and variable. But it still gives error "expecting a numeric expression here" at the last line i.e. line containing '}'
| Code: | abc(){
int key,in;
start_input: lcd_putc("\f1:Temp Thresh.\n2:Level Thresh.");
key=wait_kbd_getc();
switch(key){
case 1: selection=1; lcd_putc("\fSet Temp(0-150)\n"); goto start_temp;
case 2: selection=2; lcd_putc("\rSet Level(0-100)\n"); goto start_level;
case '#': in=0; goto end_input;
default: goto start_input;
}
start_temp: key=wait_kbd_getc();
switch(key){
case '*': if(in>150){lcd_putc("\fOut of range...");
delay_ms(1000);in=0; lcd_putc("\fSet Temp(0-150)\n");
goto start_temp;}
else return(in);goto end_input;
case '#': in=0; goto start_input;
default: in=(in*10)+key; lcd_putc(key); goto start_temp;
}
start_level: key=wait_kbd_getc();
switch(key){
case '*': if(in>100){lcd_putc("\fOut of range...");
delay_ms(1000);in=0; lcd_putc("\fSet Level(0-100)\n");
goto start_level;}
else return(in);goto end_input;

As PCM told you earlier, you are going to have to do some of the work yourself.
Comment out sections of the code until it compiles then put them back one at at time until you find the culprit.

Search:
I am minded to a port where d pic16f887 have a 4x3 keypad and Nogra make it work, this project originally worked well with a PIC16F877A but we have a bad connection Reliz burn, and going to buy indicaroon us that this is the replacement and half cost.
I have to send two draft pic 16F877A with each other with the pic16f887 in each folder is a diagram of proteus 7.2 and ccs compiler used is used inside the MPLAB environment.
