LABS 0.3.3 Pertinent Information The basic program flow is depicted in Figure 0-1. FIGURE 0-1: LAB 0 BASIC PROGRAM FLOW The template assembly file sets up this basic program flow. The student will need to add the appropriate code to the relevant sections of the file lab0-intro.s. As noted in the Pre-Lab, the maximum delay of a delay loop is about 0.016 seconds. Further delaying will be required to obtain the interval of one second. A nested loop (burying one loop within another loop) is one way to accomplish this. Hint: We advise that you start by writing simple code to initialize the LED port pin and turn the LED on before you dive in and write the delay loop. This will ensure that the project compiles and the device is programmed properly with the simplest code. Debugging of the delay loops will then be confined to just that section of code. 0.3.4 Creating a New Project See Appendix A. “Creating an MPLAB IDE Project” for details about using the Project Wizard to create a new project from scratch. The examples show the three files required to add to the project. In order to view the various files in the project, ensure that you have the Project Toolbar enabled. This is done by selecting View>Project in the menu. It is also useful to be able to view the output window. This will display various status messages during the process of assembling and linking the project. To enable this window, make sure View>Output is selected in the menu. To run the assembler and linker to create the application binary, use the “Make” command. You can access this through the menu Project>Make or using the shortcut “F10” function key. If the make command is successful, the “BUILD SUCCEEDED” message will display at the end of the output window. DS51963A-page 10 2011 Microchip Technology Inc.
0.3.5 Programming the Device In order to program the device, the build must complete successfully. This will create the binary image that is required to load into the device Flash. You must configure MPLAB IDE to use the licensed debugger circuit that resides on the MX PIC24F EDU module, see Figure 0-2. In MPLAB IDE, select “Licensed Debugger” from the menu Programmer>Select Programmer>Licensed Debugger. FIGURE 0-2: SELECT PROGRAMMER Now all that is needed is to program the device. To do this, ensure the programming USB cable is connected, and select Programmer>Program from the menu. The output window will display the status of the process. Any errors will be noted in this window. Once programming is complete, the device should immediately begin to execute the code. If successful, you will see the LED blink at the intended rate. 2011 Microchip Technology Inc. DS51963A-page 11
