Well, the first thing you need is a 'C' compiler. Start MPLAB and configure the tools to include the compiler. Then start a new project (use the Wizard if you like) and open a new file. Copy the code into the new file and save it with ".c" at the end of the name. Then add the file to the project and press the F10 key. It should compile OK but depending on which compiler it was originally written for, you may have to make a few small changes.

Thank You. But now i have and another problem.Actually this is a program for digital temperature monitoring system where keypaid, LCD, Buzzer, LED,coller are interface. But my question is that how can i burn this code to the microcontroller. I have a PIC burner. Please inform me details.

Compile your codes,the important output file is .hex file ,then with the downloader softwares of your burner download the .hex file into your Microcontroller.
Hope this help.!!

I have done it. Its ok. but what i have to do to burn this program into the microcontroller. or what have to do after this step?? Please help me.

Hello guy,how man programs (softwares) are u using?
Let give u an exampkle me I am using PIC PGM programmer (burner) for downloading .hex file in the pic. I use also ccs c compiler as code editor so after writing the codes with ccs C Icompile and Build it then It creates for me the .hex file which now I use the pic downloader Ver 4.0 for downloading my .hex file in My microcontroller.

Hope thus helps.

You need hardware to move the data in the hex file to the silicon inside the PIC. There are many programming units on the market or you can build your own. I recommend the Pickit 2 or Pickit 3 from Microchip. The hex file is actually a plain text file with information on your program and the addresses inside the PIC where it is to be saved. If you Google for "intel hex format" it should give you details.

Brian.

Just do what betwixt has told you ,tell us if you have a device which might help you to upload your .hex file in your microcontroller.

I have a PIC Programmer. Pic kit2 v 2.61i burner.

Then all you have to do is connect the Pickit 2 to the PIC using the pins named in the data sheet, select the device in the Pickit software and load the hex file. When you click the "Write" button it will decode the hex file and put the data into the PIC for you. Simple as that!

Brian.
