Well, give it a try.

SHADIQUE · Dec 26, 2016

yes sir your hex file is working on my hardware and not give any types of error.
how to solve this problem sir.
i want to know procedure to write .
please help me sir

hello sir ,
please tell me how to setting andi want to see your source code .
please help me

Hello everyone,
i am new in pic controller programming.
I am doing a project on PIC16f72 and using mikroc pro compiler.
The problem i am facing is, according to datsheet of PIC16f72 the value of config word should be 0x3fb2 in case of external osc(4 Mhz).
i have tried every option of config word setting but still didn't get that value of config word...
It seems me that's why i am even not able to blink a led through micro.
Please help me to overcome from this situation and suggest possible way to sort out it.

You will use pickit2 as a programmer.

See the attached image. You don't have to worry about unimplemented bits. The Compiler will handle it.

not woking itried all thing according datashheet but not get output while i am change pic16f72 insteadof pic16f72 then working but some problem i am facing when i interfaced switch with ic

Can't help you without seeing your exact circuit including power supply.

Hello,
I can't send complete(due to complexity) circuit but can explaine about it.
One thing,when i choose PIC16f722 in place of PIC16f72 i get same config word 0x3fb2 and get some output using pic16f72 controller.
Now i am able to control four 7 seg and 5 leds.
But now facing another problem.

Here shown in pics there r 4 7 seg display named displa1,display2 ,display3,display4 and micro pins to whom they connected.
display1 and 2 used for timer purpose(00-99) and 3 and 4 used to show voltage of ADC pic as (0.0 to 5.0)

Iam able to display value(00-99) in timer sec and now trying to increse and decrese it with switch.
But it is not working properly.
here i am posting my code.

What problem i am facing is when i put unit =9 ,dec=9....it decreaces automatically from 99 to 00.

Hi,

But it is not working properly.

Means what?

Please learn to give exact error descriptions.

One thing,when i choose PIC16f722 in place of PIC16f72 i get same config word 0x3fb2 and get some output using pic16f72 controller.

For this particular point I have stated earlier that you need not to stick to get configuration word for 16F72 as 0x3FB2. When you compile the code in mikroC with configuration word similar to 0x3FB2, you will get output of 0x12. The compiler ignores the unimplemented bits. However, this will not make any problem in burning the device. skip the verification while burning the device. For this all that you need to do is untick the "Verify After" box of your programmer. See the image. Thus you will be able to burn 16F72 with configuration word of 0x0012 or so.

Iam able to display value(00-99) in timer sec and now trying to increse and decrese it with switch.

I am not clear what you are trying to increase or decrease. Give some more detail of your requirement.

Have you tried with another pic16f72 microcontroller? just in case if the MCU is damaged.
I am sharing the below configuration settings for PIC16F886 MCU, which you can refer as an example,

Code:

; CONFIG1
; __config 0x20F1
__CONFIG _CONFIG1, _FOSC_HS & _WDTE_OFF & _PWRTE_OFF & _MCLRE_OFF & _CP_OFF & _CPD_OFF & _BOREN_OFF & _IESO_OFF & _FCMEN_OFF & _LVP_OFF
; CONFIG2
; __config 0xFFFF
__CONFIG _CONFIG2, _BOR4V_BOR40V & _WRT_OFF

Ref: **broken link removed**
the example which they have given in the above website, i have tried and it was working.

No, the mcu is not damaged. The configuration word programming fails due to verification mismatch. Just disable the verification step of the programmer and see successful burning. Soon I am uploading the image.

See the image and act accordingly.

Yes swapan......it's now flashing the controller and works according to software after untick the varification box.....
Hello klaust...
I have three push buttons in haedware with the help of them i have to increase and decrease the value on timer sections as i shown in picture.
**broken link removed**
I posted my code above....i have many times used same logic with 8051 series controllers and every time i get results.
But here this logic not working for me.....As i mentioned earlier i am not much familiar with PIC controller and may be not defined the ports correctly.
See..when use this code(posted with this comment) able to make increment and show it to timer section....but when i try to make increament or decrement ..it automatically decreases the value....
suppose if i put the unit=9 & dec=9 in code whqn it comes in while lope decrease it value form 99 to 00.(see the above codes, comment #29).

Code:

void main()
  {
       int x;
      // TRISA = 0b00110101;
       TRISA = 0xff;
       //TRISA=0b00000000;
       TRISB = 0X00;
       TRISC = 0x00;
       relay=0;// relay 0 to onn and  1 to off
       delay_ms(500) ;
       led_gnd=cc_1=cc_2=cc_3=cc_4=1;
       unit=0,dec=0;ins_unit=0,ins_dec=0;;
       while(1)
       { 

                  for(x=0;x<50;x++)
                  {
                    cc_3=1;cc_2=0;
                    PORTB=disp_2[unit];
                    delay_ms(50);

                    cc_2=1;cc_1=0;
                    PORTB=disp_1[dec];
                    delay_ms(50);

                    cc_1=1;cc_4=0;
                    PORTB=disp_2[ins_unit];
                    delay_ms(50);

                    cc_4=1;cc_3=0;
                    PORTB=disp_1[ins_dec];
                    delay_ms(50);
                  }
                  if(unit==9 && dec == 9)
                  ;
                  else
                  {
                   unit=unit++;
                   if(unit>9)
                   {unit=0;dec=dec+1;}
                  }
      }
                  

      }

Use this desktop recorder and make simulation video and post it. Show what is happening.

Aussie Susan · Jan 9, 2017

I must admit I'm not sure what the result of the code line:

Code:

unit=unit++;

would be.
The 'unit++' will provide the original value of 'unit' to the assignment and THEN increment it.
The question then becomes the order in which the compiler generates the code for the increment and the assignment. If the increment is performed first and then the assignment, I suspect the outcome will be that the assignment (of the original value) will overwrite the incremented value and so the whole statement does nothing.
On the other hand, if the assignment occurs first and THEN the increment, you will get what you intend.
I would strongly suggest that to either use 'unit = unit + 1;' (or 'unit += 1;') or 'unit++;' so that there is no ambiguity.
