STM32 CubeMX 簡(jiǎn)介

CubeMX (全稱(chēng) STM32CubeMX) 是 ST 公司推出的一款用于 STM32 微控制器配置的圖形化工具. 它能幫助開(kāi)發(fā)者通過(guò)直觀的圖像界面快速完成 STM32 微控制器的硬件配置, 外設(shè)初始化以及中間件設(shè)置等工作. 通過(guò) CubeMX, 開(kāi)發(fā)者可以大幅提高開(kāi)發(fā)效率, 降低開(kāi)發(fā)難度, 尤其是對(duì)于剛接觸 STM32 的新手.

CubeMX 的主要功能和特點(diǎn)如下:

1. 硬件配置: 通過(guò)圖形化界面, 我們可以方便地配置 STM32 微控制器的引腳, 時(shí)鐘樹(shù)以及電源設(shè)置等, 無(wú)需手動(dòng)查閱數(shù)據(jù)手冊(cè)
2. 外設(shè)初始化: 支持 STM32 系列微控制器的各種外設(shè), 包括定時(shí)器, UART, I2C, SPI 等. 我們可以通過(guò)簡(jiǎn)單的操作, 對(duì)外設(shè)進(jìn)行參數(shù)設(shè)置和功能配置
3. 中間件設(shè)置: 內(nèi)置了 ST 公司提供的各種中間件, 如 FreeRTOS, LwIP, USB Device 等. 我們可以通過(guò) CubeMX 輕松地為項(xiàng)目添加所需的中間件
4. 代碼生成: 根據(jù)配置的硬件和外設(shè)參數(shù), CubeMX 可以自動(dòng)生成初始化代碼, 支持不同的 IDE, 如 AR, Keil, STM32CubeIDE 等. 生成的代碼遵循 HAL 庫(kù)標(biāo)準(zhǔn), 方便開(kāi)發(fā)者進(jìn)行二次開(kāi)發(fā)
5. 項(xiàng)目管理: 可以創(chuàng)建, 打開(kāi)和保存項(xiàng)目, 方便開(kāi)發(fā)者對(duì)多個(gè)項(xiàng)目進(jìn)行管理. 同時(shí), 還指出導(dǎo)入已有的項(xiàng)目, 便于后續(xù)的項(xiàng)目維護(hù)和優(yōu)化

新建 STM32 CubeMX 工程步驟

1. 工程初步建立: 新建工程, 選擇芯片型號(hào)
2. 時(shí)鐘模塊配置: 設(shè)置 HSE, LSE, MCO
3. 時(shí)鐘系統(tǒng)配置: PLL, SYSCLK, AHB, APB1, APB2 等等
4. GPIO 引腳配置: 以連接在 LED 燈的 IO 為例介紹如何配置
5. Cortex 內(nèi)核配置: SYS (DEBUG) 配置, NVIC (優(yōu)先級(jí)分組)
6. 生成工程源碼: 設(shè)置工程, MDK 等, 最后生成代碼工程
7. 編寫(xiě)用戶程序: 在 main.c 文件預(yù)留的位置編寫(xiě)代碼
