Keil MDK STM32 Project Template Creation Guide
This guide introduces the STM32 firmware library, its download sources, directory layout, and the essential files required for a Keil MDK‑ARM project template. It explains how to obtain the STM32F10x standard peripheral library (version 3.5) from the STMicroelectronics website and describes the library’s folder structure, including CMSIS, driver sources, and example projects.
The document then details the Keil MDK‑ARM environment (version 4.74), showing how to set up a new project, configure simulation debugging, and use the Logic Analyzer to monitor signals such as PC0. It provides practical instructions for creating, compiling, and testing a template that can be reused across STM32F10x projects. This manual is written in Chinese.
Covers: STM32 Firmware Library Overview · STM32 Firmware Library Download · STM32 Firmware Library Directory Structure · Keil MDK‑ARM Software Overview · Creating a Keil Project Template · Simulation Debugging with Logic Analyzer

Keil ULINK Flash Debugging and Download Setup Guide
This manual shows how to set up the ULINK emulator within the Keil uVision3 IDE for ARM chip development. It assumes a Keil project is already created and a sample LED program is ready.
The document walks through target options, memory layout, selecting ULINK as the debugger, configuring flash download settings, and adding the appropriate flash programming algorithm before performing a download or starting a debug session. This manual is written in Chinese.
Covers: Project Options · LA Locate (Memory Layout) · Debug Tab Settings · Utilitise Options · Flash Download Setup · Adding Flash Programming Algorithm
Keil C51 User Manual
This manual provides a comprehensive guide to the Keil C51 development environment, including system overview, installation steps for both DOS and Windows versions, and descriptions of the various tools such as uVision, Ishell, and dScope.
It also covers advanced programming topics, library function references, example projects, and detailed instructions for using the dScope and tScope debuggers to test and debug 8051‑based applications. This manual is written in Chinese.
Covers: System Overview · Installation · Tool Package Functions · IDE Usage · Compiler Directives · Debugging with dScope and tScope

Keil Cx51 Compiler User Manual
This manual introduces the Keil Cx51 compiler, a tool for developing software for 8051 microcontrollers. It explains how to set up the environment, compile source files, and manage output, with detailed sections on command‑line usage and compiler options.
The document also describes language extensions, preprocessor directives, supported 8051 variants, memory models, and advanced programming techniques such as custom startup files and real‑time function tasks. Each chapter includes reference tables and examples to help users apply the compiler to their projects.
Covers: Introduction · Compiling with the Cx51 Compiler · Control Directives · Language Extensions · Preprocessor · 8051 Derivatives
