This is a very quick guide to allow you to assemble and generate the programmer HEX files from source code files downloaded from the Picprojects website. Many of the projects on the site already provide the necessary HEX file to program into the PIC.
In this case all you need to do is download the HEX file and program it into the PIC, you do not need to do anything else. Other projects on the site allow you to modify or edit the source code to suit your own needs. With these projects it is necessary to assemble the modified source code to create a new HEX file. To turn the source code into something that can be programmed into the actual PIC microcontroller chip you need to assemble the code. This is done using the MPASM assembler which takes the source files and creates a HEX file that your programmer hardware can write into the PIC chip. You can do this by opening the source code files in the MPLAB IDE program and using the Quickbuild option to generate the HEX file. If you have a PICkit2 programmer attached you can also program the generated HEX file directly into the PIC from within MPLAB.
For other programmer hardware you will need to use the application that came with the programmer to write the HEX file into the PIC. Download the source code for the project you are interested in from the Picprojects website and save or unzip all the files to a working directory. Run the Microchip MPLAB IDE application. From the menu select File – Open and select the file with the . They are named in the . Some code may require you to open and edit one of the . If this is the case it will be covered in the documentation on the project page.

Don’t use the project wizard or or attempt to add the code to a project. It may not assemble correctly if you do. Select the correct PIC type from from the drop down list as shown below. The projects on the Picprojects website use a number of different PIC microcontrollers. You must select the same device that is used in the project for the source code to assemble correctly.
If you need to edit and change the contents of one of the include files before assembling, open the file and make the changes. When you’ve done, save the file before going to the next step. Highlight the file with the . Next select Quickbuild from the Project menu. The Quickbuild option will run the Microchip MPASM assembler that creates the . HEX file from the source .
Note: if the Quickbuild menu option doesn’t show the name of the . Once the Quickbuild has finished check the output window to make sure the build succeeded. If you get the ‘Build Succeeded’ text at the end you will find a . HEX file in the working directory with the same name as the . HEX if the build is successful.
If there are any errors reported here, or the build fails you need to investigate and fix them before programming the PIC. Be aware that if the . HEX file already exists from a previous successful build and the build subsequently fails, the . HEX file in the working directory is the one from the last successful build.
Halting build on first failure as requested. If you see an error 301 similar to the one shown below the processor selected in the device drop down list doesn’t match the one specified in the source code. Select the correct processor before moving to the next step. Select the correct processor from the Configure menu. The code on my website is written as absolute code. I’ve seen the 151 error when people have tried to build it as relocatable code.
