# 2. Introduction to Keil5 Debugging Tools

In Keil5, debugging is a crucial part of the development process, helping developers locate and resolve issues within programs. Below, we will introduce the common debugging tools in Keil5 and their functionalities.

### 2.1 Overview of Keil5 Debugging Tools

As a powerful Integrated Development Environment, Keil5 offers a variety of tools for debugging, mainly including:

- **Source-Level Debugger**: Capable of single-stepping through source code, setting breakpoints, and viewing variable values.
- **Peripherals and Logic Analyzer**: Tools for debugging peripherals and collecting and analyzing signals through a logic analyzer.
- **Event Recorder**: Records system events, aiding in the analysis of program execution details.

### 2.2 Analysis of Main Debugging Tools' Functions

#### Source-Level Debugger

The Source-Level Debugger is one of the most commonly used debugging tools in Keil5, featuring:

- **Single-stepping (Step Into/Over)**: Executes code line by line, facilitating the tracking of program execution.
- **Setting/Clearing Breakpoints**: Places breakpoints within the code that halt program execution upon reaching them.
- **Watching Variables**: Enables real-time viewing of variable values, aiding in understanding program status.

By fully utilizing the features of the Source-Level Debugger, developers can debug programs more efficiently, enhancing development productivity.

# 3. Introduction to Keil5 Simulation Tools

Keil5, as a robust development tool for embedded systems, provides a wealth of simulation features, assisting developers in debugging and verifying their embedded applications more effectively. In this chapter, we will introduce the simulation tools in Keil5, including their overview and usage.

#### 3.1 Overview of Keil5 Simulation Tools

The simulation tools in Keil5 mainly include an emulator, emulator configuration, and simulation speed control. These tools allow developers to conveniently simulate the target hardware environment and debug program behavior.

#### 3.2 Using Simulation Tools

In Keil5, the simulation process can be carried out in the following steps:

1. **Selecting an Emulator**: Within Keil5, different emulators can be selected for simulation, such as ULINK2, ULINK-ME, etc. Choosing the appropriate emulator can better adapt to the target hardware environment.

2. **Configuring the Emulator**: Further configuration of the emulator can be done within the simulation tool,
