【STM32F429开发板⽤户⼿册】第29章STM32F429的系统bootloader之。

第29章 STM32F429的系统bootloader之USB DFU⽅式固件升级本章节为⼤家讲解使⽤系统bootloader做程序升级的⽅法，即使不依赖外部boot引脚也可以⽅便升级。

DFU的全称是Device Firmware Upgrade,即设备固件升级29.1 初学者重要提⽰29.2 跳转到系统bootloader的程序设计29.3 STM32CubeProg的安装说明29.3 STM32CubeProg的程序下载说明29.4 USB DFU⽅式系统bootloader驱动移植和使⽤29.6 实验例程设计框架29.7 实验例程说明（MDK）29.8 实验例程说明（IAR）29.9 总结29.1 初学者重要提⽰1. 学习本章节前，务必优先学习第28章。

2. 本章⽤到的相关软件和⽂档下载：。

3. 软件STM32CubeProg和DfuSe都⽀持USB DFU，但是两个软件不能都安装使⽤，因为这两个软件的USB驱动不同，导致⼯作在系统bootloader模式的板⼦通过USB线接到电脑端时，只有⼀个软件的驱动被识别。

4. DfuSe是⽼版的USB DFU软件，不推荐⼤家使⽤了。

建议使⽤STM32CubeProg，此软件实现了之前的DfuSe，STLINK⼩软件和Flashloader三合⼀，并且⽀持外部EEPROM，NOR Flash，SPI Flash，NAND Flash等烧写，也⽀持OTA编程。

5. 本章节的USB DFU的下载软件采⽤STM32CubeProg，如果想使⽤DfuSe的话，此贴有详细说明：。

6. 当芯⽚⼯作在系统bootLoader的USB DFU模式，更新完毕程序后，不会⾃动退出USB DFU，需要重新复位芯⽚后才会退出。

由于DFU模式会⽤到USB线，插拔USB线是难以避免的，所以是否⽀持⾃动退出，并不影响。

STM32学习笔记（⼀）——初⼊门F429⼀、前情电⼦信息专业，有嵌⼊式开发项⽬的经验，但不算完全了解。

上课没认真听，项⽬全靠吃⽼本，现在为了毕业设计和⼯作打算认真从头学习嵌⼊式开发。

⼆、⽬前情况看了⼀个星期正点原⼦关于STM32F429库函数开发的书，主要看的部分是ucos、fatfs和⾳乐播放器这⼏个部分，看的稀⾥糊涂的，应该是因为基础太差。

从头开始看之后，明⽩了很多，但还有很多稀⾥糊涂。

就去看了野⽕的资料，野⽕写的很好，看完清晰⾥很多，包括寄存器概念，⼿册的应⽤这种基础知识都写得很清晰明了，推荐⼤家看野⽕的教材。

我⽬前的打算是看野⽕的教材，⽤正点原⼦的例程和开发板。

正点原⼦的各种项⽬做的确实很好很有参考性。

三、笔记（⼀）STM32芯⽚图M4内核是ARM公司做的，芯⽚集成设计由ST设计的。

除内核以外的部分，是⽚上外设，内核与总线之间通过各种总线连接，其中其中主控总线有8条，被控总线有7条，具体见图其中圆圈的部分表⽰可以通信，黄⾊部分是主控总线，粉⾊部分是被控总线。

（⼆）存储器映射存储器本⾝不具有地址信息，它的地址是由芯⽚⼚商或⽤户分配，给存储器分配地址的过程就称为存储器映射，具体见图。

如果给存储器再分配⼀个地址就叫存储器重映射。

这4GB的地址空间中，ARM已经粗线条的平均分成了8个块，每块512MB，每个块也都规定了⽤途，具体分类见表格。

Boock0⽤来设计成内部FLASH，Block1⽤来设计成内部RAM，Block2⽤来设计成⽚上的外设。

这是⽐较重要的三块。

（三）寄存器映射Block2⽚上外设，四个字节为⼀单元，共32bit，每⼀单元对应不同的功能，控制这些单元时就可以控制不同外设。

除了找到每个单元的起始地址，然后通过C语⾔指针的操作⽅式来访问这些单元外，还们可以根据每个单元功能的不同，以功能为名给这个内存单元取⼀个别名，这个别名就是我们经常说的寄存器，这个给已经分配好地址的有特定功能的内存单元取别名的过程就叫寄存器映射。

STM32F429开发板用户手册介绍STM32F429(32F429IDISCOVERY)开发板可以帮助你去学习高性能STM32F4系列，并去开发你自己的应用。

它包含了一个STM32F429ZIT6和一个嵌入ST-LINK/V2调试接口，2.4吋TFTLCD，64MbitsSDRAM，ST微机电陀螺仪，按键和USB OTG接口。

1约定下表提供了一些约定惯例，目前的文档可能会用到。

2快速入门STM32F429开发板是一种廉价且易于上手的开发套件，可以让使用者快速评估和开始STM32F4的开发工作。

在安装和使用产品以前，请接收评估产品许可协议。

2.1启动跟随以下顺序来设置STM32F429开发板并开始开发应用：1、确认跳线JP3和CN4被设置为“on”（开发模式）2、连接STM32F429Discovery开发板CN1到PC，使用USB电缆（type A/mini-B）,开发板上电。

3、屏幕上以下应用可用：时钟日历和游戏视频播放器和图片浏览器（播放浏览USB大容量存储器上的视频和图片）性能显示器（观察CPU负载和图形测试）系统信息4、演示软件，也像其他软件例程，运行你用来开发STM32F4。

5、从例程开始开发你自己的应用吧。

2.2系统要求•Windows PC(XP,Vista,7)•USB type A to mini-B cable2.3支持STM32F429开发板的开发工具•Altium:TASKING™VX-Toolset•Atollic:TrueSTUDIO•IAR:EWARM•Keil™:MDK-ARM2.4订购码要订购STM32F429Discovery kit，请使用STM32F429I-DISCO订购码。

3特性STM32F429Discovery开发板提供一下特性：•S TM32F429ZIT6具有2MB闪存，256KB的RAM，LQFP144封装。

【STM32F429开发板⽤户⼿册】第41章STM32F429的LTDC应⽤之LCD汉字显。

第41章 STM32F429的LTDC应⽤之LCD汉字显⽰和2D图形显⽰本章教程为⼤家讲解LTDC应⽤中最基本的汉字显⽰和2D图形显⽰功能实现。

41.1 初学者重要提⽰41.2 LCD相关的基础⽀持41.3 LCD硬件设计41.4 LCD驱动设计41.5 LCD板级⽀持包（bsp_ltdc_429.c和bsp_tft_lcd.c）41.6 LCD的驱动移植和使⽤41.7 实验例程设计框架41.8 实验例程说明（MDK）41.9 实验例程说明（IAR）41.10 总结41.1 初学者重要提⽰1. 学习本章节前，务必优先学习第40章，需要对LTDC的基础知识和HAL库的⼏个常⽤API有个认识。

2. 本章的第4⼩节LCD驱动设计⾮常重要。

3. 如果⾃⼰观察的话，LCD上电会有⼀个瞬间⾼亮的问题，在此贴进⾏了描述：。

这个解决⽅案已经应⽤到本章配套的例⼦上。

4. 本章节⽤到的汉字⽅案会在下章专门为⼤家讲解，下⾯是⼩字库的制作⽅法：。

5. 调试状态或者刚下载LCD的程序到⾥⾯，屏幕会抖动，这个是正常现象，之前F429就有这个问题，详情看此贴：。

41.2 LCD相关的基础知识41.2.1 显⽰屏相关知识显⽰屏的结构有必要给⼤家普及下，这⾥我们通过如下三种类型的显⽰屏进⾏说明，基本已经涵盖我们常⽤的⽅式了。

RA8875 + RGB接⼝裸屏⾸先RA8875是⼀个显⽰屏控制器，⾃带显存，它的作⽤就是让不⽀持RGB接⼝的MCU也可以使⽤RGB接⼝的⼤屏。

这起到了⼀个桥接的作⽤，可以将RGB接⼝屏转换成8080总线接⼝、SPI接⼝或者I2C接⼝⽅式。

这种情况下，甚⾄低速的51单⽚机都可以外接⼤屏了。

另外像SSD1963也是同样的作⽤。

ili9488类显⽰屏这种类型是把显⽰控制器和显⽰屏都集成好了，⽀持8080总线接⼝，有些还⽀持SPI或者I2C接⼝，⽽且显存也都集成了，不过主要是驱动⼀些⼩屏。
