Step 2: Create a New Project
To create a new project, launch IAR Embedded Workbench for 8051 and select File > New > Workspace. A workspace is a container for one or more projects. You can name your workspace and choose a location to save it. Then, select Project > Create New Project to create a new project within the workspace. You can name your project and choose a project template from the list of available templates. The project template contains configuration files, code examples, and project settings for a specific device or application.
Step 3: Configure Your Project
To configure your project, select Project > Options to open the Project Options dialog box. Here you can set various options for your project, such as device selection, compiler options, linker options, debugger options, and output formats. You can also use the Quick Settings menu to quickly select predefined settings for common devices and applications. Make sure to select the correct device and debugger for your project.
Step 4: Write Your Code
To write your code, use the editor window in IAR Embedded Workbench for 8051. You can write your code in C or C++, or use assembly language if you prefer. The editor provides syntax highlighting, code completion, code folding, and other features to help you write your code efficiently. You can also use the code templates menu to insert common code snippets into your source files.
Step 5: Build Your Project
To build your project, select Project > Make or press F7. This will invoke the compiler, assembler, linker, and library tools to generate an executable file for your project. The build process will also produce a map file that shows the memory layout of your program. You can view the build messages in the Output window at the bottom of the IDE. If there are any errors or warnings in your code, you can double-click on them to jump to the corresponding source line.
Step 6: Debug Your Project
To debug your project, select Project > Download and Debug or press Ctrl+D. This will download your executable file to your target device and launch the C-SPY Debugger. The C-SPY Debugger is a comprehensive debugger that provides an 8051 simulator and extensive support for debugging probes and target systems. It also supports RTOS-aware debugging, multicore debugging, power measurement, function profiling, timeline analysis, data visualization, and more.
The debugger window consists of several panes that show different aspects of your program execution, such as source code, disassembly code, registers, memory, variables, watch expressions, breakpoints, call stack, etc. You can use the toolbar buttons or keyboard shortcuts to control the execution of your program, such as run (F5), stop (F2), step into (F11), step over (F10), step out (Shift+F11), etc. You can also use the command window to enter debugger commands.
