**What is the Development Environment of ARM?**
1. **ARM SDT (Software Development Tools):**
ARM SDT was a set of development tools introduced by ARM for easier application software development on ARM processors. It supported all ARM processors up to ARM9. With the Angel resident program and JTAG emulator, users could easily develop applications using this environment. However, ARM announced the replacement of SDT with ADS 1.0 in version 2.5.1, and it is no longer maintained.
2. **ARM ADS (Advanced Development Studio):**
ARM ADS is an integrated development environment (IDE) that replaced ARM SDT. The latest version is ADS 1.2. It evolved from SDT by enhancing some modules and replacing others. It includes modern IDE features such as project management, code editing, and debugging. It supports all ARM processors and allows for processor emulation and debugging through affordable JTAG boards.
3. **EmbestIDE:**
Developed by Shenzhen Yingwei Special Information Technology Co., Ltd., EmbestIDE is an ARM IDE that works with the PowerICE simulator from Yinghao Special Information Technology Co., Ltd. This combination enables simulation and debugging of ARM processors.
4. **RealView MDK (Microcontroller Development Kit):**
RealView MDK is one of ARM's primary development environments for microcontrollers. It offers a user-friendly interface and powerful tools, supporting ARM processors with the help of the ULINK2 emulator for simulation and debugging. It also provides peripheral simulators for certain ARM chips, allowing developers to simulate peripheral behavior directly within the environment.
5. **RealView Developer Suite (RVDS):**
Designed to meet the challenges of System-on-Chip (SoC) debugging, RVDS provides multi-core debugging, application development, and code generation for all ARM processors and Cortex CPUs. It also offers integration with third-party components, making it a versatile tool for advanced embedded system development.
6. **Multi 2000:**
Developed by Green Hills Software, Multi 2000 is an IDE that supports C/C++ and Embedded C++. It runs on both Windows and Unix platforms and supports remote debugging of various devices. It also supports multiple processors, including 16-bit, 32-bit, 64-bit, and DSPs, and can handle multi-processor debugging.
7. **SldView for ARM:**
This is another integrated development environment used for ARM-based projects, though it is less commonly referenced compared to other tools.
**Introduction to Building an ARM Architecture MCU Development Environment Using Eclipse**
Eclipse is a flexible framework that allows developers to build integrated development environments (IDEs) by installing different plugins. For example, KDS from Freescale or CCS6 from TI are based on Eclipse. To create an ARM development environment, you need:
IDE = Eclipse (editor) + arm-none-eabi-gcc (compiler) + make (build tool) + J-Link (debugger).
**Install JDK**
Since Eclipse is written in Java, you must first install the Java Development Kit (JDK). This is essential for running Eclipse smoothly.
**Install Eclipse**
Download the Eclipse IDE for C/C++ Developers. It serves as the main platform for managing projects, editing code, and organizing files.
**Install GNU ARM Eclipse Plug-ins**
These plugins provide support for J-Link and OpenOCD debugging. They enable GDB server functionality, which helps parse debug signals from arm-elf-gdb and control hardware like J-Link or OpenOCD.
**Install arm-none-eabi**
This is a cross-compilation toolchain provided by GNU, used for compiling ARM MCUs such as ARM7, ARM9, and Cortex-M/R chips. It’s ideal for applications without an operating system. If you're working on Linux projects, you’ll need the arm-linux-eabi toolchain instead.
**Install MSYS**
MSYS is a minimal POSIX environment for Windows, providing basic commands like bash and make. It’s often used alongside MinGW to build tools for Windows. MSYS2 is an upgraded version that includes package management via pacman and supports both 32-bit and 64-bit systems.
**Install J-Link Driver**
J-Link is a JTAG emulator from SEGGER, supporting various ARM cores like ARM7, ARM9, Cortex-M, and Cortex-A series. It integrates well with IDEs and supports a wide range of ARM processors.
**New Project Setup**
In Eclipse, go to [File] > New > C Project > Executable > Empty Project, and select the "Cross ARM GCC" toolchain. Then configure the paths for the build tools and toolchain. Set up the debugger configuration with "GDB SEGGER J-Link Debugging" and specify the device name, such as "Cortex-A7."
PVC rigid tubes are commonly used for Cable Management and protection. They provide a secure and organized solution for routing and protecting cables in various applications, such as electrical wiring, telecommunications, and computer networking.
PVC rigid tubes are made from high-quality polyvinyl chloride (PVC) material, which offers excellent durability, flexibility, and resistance to impact, chemicals, and UV radiation. These tubes are available in different sizes and lengths to accommodate various cable sizes and installation requirements.
The rigid nature of PVC tubes ensures that cables are protected from bending, crushing, and other physical damages. They also provide insulation and shielding properties, preventing interference and maintaining signal integrity.
Installing PVC rigid tubes for cable management is relatively easy. They can be cut to desired lengths using a PVC cutter or saw, and fittings such as elbows, connectors, and couplings can be used to create bends and connections as needed. The tubes can be mounted on walls, ceilings, or floors using appropriate fasteners or adhesive.
Overall, PVC rigid tubes offer a cost-effective and efficient solution for organizing and protecting cables, ensuring a clean and professional installation.
