【正文】 re it is important to research PWM technology. It is easy to use the timer of STM32 to produce PWM output. PWM is produced by the timer of STM32. The cycle of PWM is the timer’s regular time. By calculating the frequency of square wave, dutycycle, configuring the timer and IO, then use oscilloscope displayed the PWM. Based on the STM32, by configuring the timer of STM32, PWM is displayed by oscilloscope.Key words：STM32，timer，PWM目錄第 1章 前言 ..................................................................5 ARM應(yīng)用背景 .............................................................5 研究?jī)?nèi)容 .................................................................6 研究成果 .................................................................7第 2章 STM32 處理器概述 .....................................................8 STM32簡(jiǎn)介 ...............................................................8 內(nèi)部資源 ................................................................10 CORTEXM3內(nèi)核簡(jiǎn)介 ......................................................10 STM32定時(shí)器簡(jiǎn)介 ........................................................12 通用定時(shí)器 .........................................................12 高級(jí)控制定時(shí)器 .....................................................12 小結(jié) ................................................................15第 3章 PWM 概述 .............................................................16 原理 ....................................................................16 PWM 模式 ............................................................16 互補(bǔ)輸出與死區(qū)插入 ..................................................19 PWM輸出的實(shí)現(xiàn) ..........................................................21第 4章 軟件設(shè)計(jì) .............................................................22 開發(fā)環(huán)境 ................................................................22 STM32的開發(fā)軟件 ....................................................22 MDK370 .............................................................22 軟件實(shí)現(xiàn) ...............................................................23 設(shè)計(jì)標(biāo)準(zhǔn) ...........................................................23 程序流程圖 .........................................................25第五章 測(cè)試及結(jié)果 ...........................................................26 JTAG仿真器介紹 .........................................................26 測(cè)試 ....................................................................27 現(xiàn)象及結(jié)果 ..............................................................28結(jié)論 .........................................................................31致謝 .........................................................................32參考文獻(xiàn) .....................................................................33ARM處理器ADCI/O 接口鍵盤RAM LED傳感器轉(zhuǎn)換器LCD DACEPROM主機(jī)第 1 章 前言 ARM 應(yīng)用背景如今，學(xué)習(xí)一種處理器的就有許多ARM內(nèi)核的處理器可供使用，現(xiàn)在社會(huì)已步入嵌入式學(xué)習(xí)階段。It is easy to use the timer of STM32 to produce PWM output. STM32的 PWM由定時(shí)器產(chǎn)生，PWM 的周期即定時(shí)器定時(shí)的時(shí)間，通過(guò)計(jì)算方波的頻率，占空比，配置定時(shí)器和 IO口，最后用示波器顯示相應(yīng)通道占空比的方波即可。On the intention of study on ARM, timer of STM32 produce pulses PWM (width modulation) is studied in this paper.PWM就是某個(gè)頻率占空比的方波，其應(yīng) 用 領(lǐng) 域 包 括 測(cè)量，通信，功率控制與變換，電 動(dòng) 機(jī) 控 制 、 伺 服 控 制 、 甚 至 某 些 音 頻 放 大 器 ， 因此研究 PWM技術(shù)具有十分重要的現(xiàn)實(shí)意義。 基于 STM32 定時(shí)器產(chǎn)生 PWM 的研究摘要隨著科技水平的提高， ARM 的應(yīng)用越來(lái)越廣泛。With the develop of technology, ARM is used in various situations.旨在對(duì) ARM的深入學(xué)習(xí)，論文對(duì) STM32 定時(shí)器產(chǎn)生 PWM(脈沖寬度調(diào)制)輸出進(jìn)行了研究。 PWM is the square wave which has a sure dutycycle and frequency. Its application fields include measurement, munication, power control and transform, motor control, servo control, even some audio amplifier. Therefore it is important to research PWM technology.本設(shè)計(jì)采用 STM32 定時(shí)器產(chǎn)生 PWM。PWM is produced by the timer of STM32. The cycle of PWM is the timer’s regular time.
