【EWARM】EWARM（IAR）的安裝過程以及GD32的IAR工程模板搭建

一、簡介

IAR官網

EWARM，即 IAR Embedded Workbench for ARM，是由 IAR Systems 開發的一款專門用于 ARM 微處理器軟件開發的集成開發環境。以下是具體介紹：

功能特性：
- 完整工具鏈支持：集成了高級編輯器、全面的編譯器工具鏈以及功能強大的調試器，支持從編碼、編譯、調試到固件下載的完整開發周期。
- 多核心支持：支持多種 ARM 核心，如 Cortex-M、Cortex-R 等，還為不同的 ARM 內核和硬件平臺提供了一系列預設的項目模板，可針對不同處理器進行優化編譯。
- 實時操作系統兼容：支持多種 RTOS，包括 FreeRTOS、RT-Thread、uC/OS 等，方便開發者在多任務或高實時性要求的應用場景中進行開發。
調試功能：
- 豐富調試接口：支持 JTAG 調試，也可使用 SWD 接口，方便開發者訪問微控制器的內部資源，如寄存器、內存和外設等，以進行實時調試和分析。
- 多種調試手段：內置的調試器提供了斷點、步進、單步、變量觀察和寄存器查看等功能，還支持事件追蹤、數據追蹤和地址追蹤等多種追蹤模式，以及代碼覆蓋率分析和性能分析等功能，有助于開發者發現程序瓶頸并優化程序性能。
主要模塊：
- 編譯器：高度優化的 IAR ARM C/C++ Compiler，具有先進的通用編譯器優化和針對特定處理器的速度優化及存儲器優化功能。
- 鏈接器：一個通用的 IAR XLINK Linker，可將編譯后的目標文件鏈接成可執行文件或庫文件。
- 建庫程序和運行庫：IAR XAR 和 XLIB 建庫程序用于創建和管理庫文件，IAR DLIB C/C++ 運行庫提供了運行時所需的函數支持。
- 調試器：IAR C-SPY 調試器是一款先進的高級語言調試器，支持源代碼和反匯編程序調試，具備復雜的代碼和數據斷點、豐富的數據監視功能等。
- 其他：還包括項目管理器、功能強大的編輯器以及命令行實用程序等。
優勢特點：
- 入門容易：相較于其他一些 ARM 開發環境，EWARM 具有較為友好的操作界面和相對簡單的配置流程，開發者能夠較快上手，適合初學者使用。
- 代碼緊湊：通過其優化的編譯器和相關工具，生成的代碼具有較高的效率，代碼體積相對較小，能夠更好地適應嵌入式系統對資源有限的特點。
- 跨平臺支持良好：從軟件模擬器到高性能的硬件調試器，EWARM 提供了廣泛的目標設備支持，可在不同的開發環境和硬件平臺上使用。

二、EWARM（IAR）安裝過程

1.點擊運行安裝程序

2.選擇第1個選項安裝IAR FOR ARM（對于ARM架構的）

3.NEXT

4.accept，NEXT

5.選擇安裝路徑（建議C盤以外，最好新建一個不含有中文的文件夾，因為后續有些版本不支持中文路徑），下一步

6.驅動

7.下一步

8.確定

9.安裝

10.等待安裝完成

11.暫時不打開軟件，暫時取消證書的安裝

12.驅動無腦裝

這是?TI Emulators 8.0.803.0（德州儀器仿真器軟件）的安裝許可協議界面，核心內容是：

1. 界面功能

呈現?德州儀器（Texas Instruments）的軟件許可協議，要求你閱讀并決定是否接受條款。
協議里有版權、使用限制、責任等法律約束內容（2004 年 3 月 11 日版本）。

2. 操作選項

接受協議（I accept the agreement）：選這個才能繼續安裝，代表你同意遵守協議條款。
不接受（I do not accept the agreement）：選這個會終止安裝，無法使用軟件。

簡單說，就是安裝前讓你確認 “是否同意德州儀器的軟件使用規則”，想裝軟件就得選 “接受”，點 “Next” 繼續流程；不想裝就選 “不接受” 或直接關窗口～

這是?TI Emulators 8.0.803.0（德州儀器仿真器軟件）?的安裝路徑設置界面，核心信息是：

1. 標題含義

“Code Composer Studio Installation Directory”：需指定軟件安裝路徑，若和 Code Composer Studio（CCS，德州儀器的集成開發環境）一起用，要選對應 CCS 版本（ccsv5/6/7）的文件夾。

2. 路徑說明

默認路徑是?C:\ti，你可以修改成其他自定義路徑（點輸入框右側文件夾圖標選位置）。
若已有 CCS，按提示選到 CCS 安裝目錄里的?ccsv5/ccsv6/ccsv7?文件夾，能讓仿真器和 CCS 更好配合。

3. 操作邏輯

選好路徑后點 “Next” 繼續安裝；想改路徑就調整輸入框內容；不想裝了點 “Cancel” 退出。

簡單說，就是讓你選 “把 TI 仿真器軟件裝到電腦哪個位置”，按需求（或默認）設好路徑，繼續下一步安裝流程～

13.打開運行，準備安裝證書

取消

14.到help下的License manager

15.點擊License下的離線激活

16.注冊機

17.將注冊機的License Number，放到離線激活里，然后，離線激活里再點擊下一步

18.NO?

19.選擇存放初始證書的位置，后面再使用這個產生一個回應的驗證證書

20.確認下一步

21.使用注冊機去使用初始證書，產生一個回應的驗證證書（真正的證書）

選擇初始證書

點擊產生?

22.回到注冊頁面，選擇回應文件

23.后續

這是?IAR License Manager（IAR 許可證管理器）?的彈窗，對應?IAR Embedded Workbench for Arm 8.32?版本，核心內容是：

1. 功能說明

你的許可證允許提取?IAR Library Source for Arm（ARM 庫源代碼包），這些代碼可輔助開發，但提取需要管理員權限（確保系統級操作權限）。

2. 操作選項

Yes：立即提取庫源代碼，點了之后會觸發管理員權限申請（可能彈 UAC 確認框），完成后把代碼放到指定路徑。
No：暫不提取，之后想提隨時能在許可證管理器里操作；若勾選?Don't notify me about this again，下次不會再彈這個提示。

3. 建議邏輯

若開發時需要調試 / 查看庫代碼（比如做底層優化、排錯），選?Yes?提取，方便后續開發；
若只是簡單用 IAR 編譯、不碰庫源碼，選?No?也不影響基礎功能。

簡單說，就是 “許可證給你權限提取 ARM 庫源碼，要不要現在用管理員權限提取”，按需選就行～

我選的yes?

24.綠色狀態，完成

三、初步新建IAR下的GD32工程模板

注：硬件平臺：立創梁山派

1.到GD32的官網下載固件庫和IAR環境支持包（環境補丁）

2.安裝IAR補丁，一定一定要以管理員身份運行才能讓其自動檢測到你安裝的IAR路徑！！！

3.新建工程文件夾IAR_GD32_Template

4.\GD32F4xx_Firmware_Library_V3.3.1\GD32F4xx_Firmware_Library_V3.3.1\GD32F4xx_Firmware_Library下的Firmware里就是外設源文件，但是，首先，在我們的工程文件夾里新建文件夾

5.搬移文件

（1）CMSIS

\GD32F4xx_Firmware_Library_V3.3.1\GD32F4xx_Firmware_Library_V3.3.1\GD32F4xx_Firmware_Library\Firmware\CMSIS的core內核文件放到CMSIS

（2）StartUp

IAR環境啟動文件

\GD32F4xx_Firmware_Library_V3.3.1\GD32F4xx_Firmware_Library_V3.3.1\GD32F4xx_Firmware_Library\Firmware\CMSIS\GD\GD32F4xx\Source\IAR下的啟動文件放到StartUp

（3）SYSTEM

\GD32F4xx_Firmware_Library_V3.3.1\GD32F4xx_Firmware_Library_V3.3.1\GD32F4xx_Firmware_Library\Firmware\CMSIS\GD\GD32F4xx下的頭文件放到SYSTEM的INCLUDE

\GD32F4xx_Firmware_Library_V3.3.1\GD32F4xx_Firmware_Library_V3.3.1\GD32F4xx_Firmware_Library\Firmware\CMSIS\GD\GD32F4xx\Source下的system_gd32f4xx.c放到SYSTEM的SOURCE

（4）USER

同時根據官方例程需要一些其他文件支持，在\GD32F4xx_Firmware_Library_V3.3.1\GD32F4xx_Firmware_Library_V3.3.1\GD32F4xx_Firmware_Library\Template尋找

根據自己習慣，分個類

（5）GD32F4xx_standard_peripheral

\GD32F4xx_Firmware_Library_V3.3.1\GD32F4xx_Firmware_Library_V3.3.1\GD32F4xx_Firmware_Library\Firmware\GD32F4xx_standard_peripheral

將外設源文件全放到GD32F4xx_standard_peripheral

6.打開IAR，創建IAR工程

7.跟keil就差不多了，就是新建組別，添加文件

8.工程配置

（1）右擊項目，選擇Options

（2）選芯片

（3）配置庫，內核文件已有CMSIS

設置外部文件夾Debug

（4）添加宏，路徑

USE_STDPERIPH_DRIVER,GD32F4XX,LV_CONF_INCLUDE_SIMPLE

下拉選擇相對路徑：

（5）輸出配置

（6）選擇下載模式

差點忘記立創梁山派用的DAP了

（7）選擇鏈接文件

Linker --> Config --> Linker configuration file? 勾選上 Override default 重設默認文件

9.編譯

保存工作空間

10.解決報錯

方法二：

重寫main.c，不用#include "gd32f450i_eval.h"

11.代碼改正

gd32f4xx_it.c

注釋led_spark();
