can check for me what wrong with my programming? cannot run in mikroC PRO

can check for me what wrong with my programming? cannot run in mikroC PRO
No reaction when i pressed the switch..it suppose will display in LCD..
can you check my coding uploaded? The coding cannot run in mikroC PRO
THANKS..

instead of #define, try using the port directly

I think tou need to read AVR GCC Tutorial (1) – Basic I/O Operations « Suhas’s Blog
You are using PORTA to read the input state (smoke) of the pin , this in not correct, the input register is PINA, PINB...
The PORTA sets the pull-up resistor when the pin is set as input.
The above article explains everything.

What is wrong with using define?

Sorry , I think you are using PIC, if this is the case ignore what I wrote, they are valid for AVR mcu.
You should include in your message the mcu you are using.

your program has been compiled in mikroC pro and it is displaying initial lcd strings (i.e; testing and 0...9).... i didnt check the subroutine... but i think the term shown below can cause a run time error.....

void setting()
{
while(sw1); //no semicolon required
{ // add braces at starting and close at end as you are considering a case i,e; when sw1 is pressed do so...
Delay_ms(100);
lcd_out(1,1,"Setting Number1 ");
x=0x30;
counter=1;
.........................
.............
.........;

similarly check other subroutines ..... if your compiler mikro C doesn't run this try reinstalling it...

but i replace while(!sw1) it will shown in lcd display..zzz

Have you setup ANSEL/H ?

Have you setup ANSEL/H ?

no i dint set..

Have you setup ANSEL/H ?

i think this instruction supports 16F877 and will show error in 16F877A type...

This must be set to define input type Analog or Digital

On the A it may be controlled via ADCON1 and/or CMCON

it is work with adding ADCON1..thanks
