Need a PIC based Line Following Robot

[mirrayhan08]

Hi Mehedi,
are you sure you need the leading '#' in the following lines?

I give the code. this code i use to compile. but show error.
I have 16f877A PIC and JDM programar with win800 program, i use maplab to compile the code.

Thanks

Hello thamid

Hi,
Paswa,
Actually I did not learn from any specific book or the internet.
I learnt from my dad who is one of the best PIC microcontroller programmers in Bangladesh.
It is very difficult to learn by oneself, but if you stick to it, you will certainly be successful. I can help you on the way.
It is not possible to learn from only one source, but from many different sources.
Stick to it. Do not give up and in the long run, you will certainly be successful.

লেগে থাকলে তুমি নিশ্চয়ই সফলকাম হবে। যারা পরিশ্রম করে এবং ধৈর্য ধরে, সাফল্য তাদের নিশ্চিত। ধন্যবাদ।

Thamid i hope you help me. plz go this link and help me

Need help to convert a c code

Paswa,
Wakibaki has given you a sincere and good suggestion on one sense.
Tahmid is also correct in his perspective. If you want to learn to program Pic, you can purchase Pic kit2 and the board. But are you in a hurry? You are a school going kid and enough time is there in front of you. Instead of lighting some LED etc. with the help of ready made board and programming with pic kit2, you may try to build one by yourself and also can make your own Training Board and by doing so, you will be learning valuable lessons, which will be useful for you throughout. You may be unsuccessful for 1/2 times but ultimately you will be successful. I will provide you the design of my programmer, will provide the source of software, from where you can collect and if cannot, I will mail you the software. You can get these from internet also. If you are interested in Assembly Language, I can post you some of my programs written for 16F84A and these I can post through this Forum, so that others who are interested can see.

When I started Pic Programming, I also faced lot of problems with programmer as it was not available in my country and no office or agent of Microchip are here and hence I went to self making route. I made those with lot of hard work but that effort gave me lot of benefit. Afterwords, I earned lot of money by selling my programmers and Training Boards for different Pics. I furnished my Laboratory lavishly with those money.

Hardwork never goes in vain and shortcut may not help you in the long run.
I will take 3/4 days more and then I will start helping you.

Thanks.

@Mehedi

I'm not sure at all, but for the code of your first post, try modifying the first six lines removing ";" :

#include <16F877A.H> //declare a PIC header
#device adc=8 //set the bit for ADC
#fuses hs, nowdt, noprotect //set the PIC protection
#use delay (clock=20000000) // set the clock frequency
#byte porta=5 //assign port a
#byte portd=8 //assign port d

Hi Paswa,
Where are you? What is your progress regarding Robot?
Thanks.

Hello, Mahbub
I have everything for a making a line following robot. it make using by pic 16f877a.
but i have a problem to convert the c source code. are you help me. i provide the source code. if you able to convert it hex format plz send it. this project is a key point in my study. plz help me...

}
else if (val1>vref) //sensor 1 is dark

Hello Switters

In this case could be useful to read my reply to your first post 😉

What do you think the leading '#' on the first six statement means?

Code is changed in your second post, are you sure compiler errors are still the same?

Yes. error still now.

 

[Switters]

Yes. error still now.

I think it's a tool/compiler problem. I believe that on the latest versions of MPLAB the source code you posted should be complied with the CCS compiler.
