Tutorial 3.7 NAMING THE PROJECT Step Three of the wizard allows you to name the project and put it into a folder. This sample project will be called 18F452Proj. Using the Browse button, place the project in a folder on the C drive named My Projects. Click Next>. FIGURE 3-5: © 2006 Microchip Technology Inc.
MPLAB® PM3 User’s Guide 3.8 ADDING FILES TO THE PROJECT Step Four of the Project Wizard allows file selection for the project. A source file has not yet been selected, so we will use an MPLAB IDE template file. The template files are simple files that can be used to start a project. They have the essential sections for any source file, and contain information that will help you write and organize your code. These files are in the MPLAB IDE folder, which by default is in the Program Files folder on the PC.
Tutorial Next, add the second file for our project, the linker script. There is a linker script for each device. These files define the memory configuration and register names for the various parts. The linker scripts are in the folder named LKR under the MPASM Suite folder. Use the file named 18F452.lkr The full path is: C:\Program Files\Microchip\MPASM Suite\LKR\18F452.lkr To copy this linker script into our project, click on the check box.
