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

【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

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。

STM32F4family.They are fully pin-to-pin,software and feature compatible with the STM32F2xx devices,allowing the user to trydifferent memory densities,peripherals,and performances(FPU,higher frequency)for agreater degree of freedom during the development cycle.The STM32F429xx devices maintain a close compatibility with the whole STM32F10xxfamily.All functional pins are pin-to-pin compatible.The STM32F429xx,however,are notdrop-in replacements for the STM32F10xx devices:the two families do not have the samepower scheme,and so their power pins are different.Nonetheless,transition from theSTM32F10xx to the STM32F42x family remains simple as only a few pins are impacted.Figure1,Figure2,and Figure3,give compatible board designs between the STM32F4xx,STM32F2xx,and STM32F10xx

Flash andSRAMThe ARM Cortex-M4with FPU processor is the latest generation of ARM processors forembedded systems.It was developed to provide a low-cost platform that meets the needs ofMCU implementation,with a reduced pin count and low-power consumption,whiledelivering outstanding computational performance and an advanced response to interrupts.The ARM Cortex-M4with FPU core is a32-bit RISC processor that features exceptionalcode-efficiency,delivering the high-performance expected from an ARM core in the memorysize usually associated with8-and16-bit devices.The processor supports a set of DSP instructions which allow efficient signal processing andcomplex algorithm execution.Its single precision FPU(floating point unit)speeds up software development by usingmetalanguage development tools,while avoiding saturation.The STM32F42x family is compatible with all ARM tools and software.Figure4shows the general block diagram of the STM32F42x family.Note:Cortex-M4with FPU core is binary compatible with the Cortex-M3core.3.2Adaptive real-time memory accelerator(ART Accelerator™)The ART Accelerator™is a memory accelerator which is optimized for STM32industry-standard ARM®Cortex™-M4with FPU processors.It balances the inherent performanceadvantage of the ARM Cortex-M4with FPU over Flash memory technologies,whichnormally requires the processor to wait for the Flash memory at higher frequencies.T o release the processor full225DMIPS performance at this frequency,the acceleratorimplements an instruction prefetch queue and branch cache,which increases programexecution speed from the128-bit Flash memory.Based on CoreMark benchmark,theperformance achieved thanks to the ART Accelerator is equivalent to0wait state programexecution from Flash memory at a CPU frequency up to180MHz.3.3Memory protection unitThe memory protection unit(MPU)is used to manage the CPU accesses to memory toprevent one task to accidentally corrupt the memory or resources used by any other activetask.This memory area is organized into up to8protected areas that can in turn be dividedup into8subareas.The protection area sizes are between32bytes and the whole4gigabytes of addressable memory.The MPU is especially helpful for applications where some critical or certified code has to beprotected against the misbehavior of other tasks.It is usually managed by an RTOS(real-time operating system).If a program accesses a memory location that is prohibited by theMPU,the RTOS can detect it and take action.In an RTOS environment,the kernel candynamically update the MPU area setting,based on the process to be executed.14/102Doc ID023140Rev2采购电子元器件选择万联芯城,万联芯城是国内一家知名电子元器件网上商城，专为终端研发客户提供电子元器件一站式配套服务，万联芯城只售原装现货电子元器件，货源渠道均来自原厂及授权代理商，品质有保证，价格有优势，为客户节省采购成本。

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。

6.1 新建工程6.1.1 新建本地工程文件夹为了工程目录更加清晰，我们在本地电脑上新建1个文件夹用于存放整个工程，如命名为“LED”，然后在该目录下新建2个文件夹，具体如下：表格 8 工程目录文件夹清单名称作用Listing 存放编译器编译时候产生的c/汇编/链接的列表清单Output 存放编译产生的调试信息、hex文件、预览信息、封装库等图 6-1 工程文件夹目录在本地新建好文件夹后，在文件夹下新建一些文件：表格 9 工程目录文件夹内容清单名称作用LED 存放startup_stm32f429_439xx.s、stm32f4xx.h、main.c文件Listing 暂时为空Output 暂时为空6.1.2 新建工程打开KEIL5，新建一个工程，工程名根据喜好命名，我这里取LED-REG，直接保存在LED文件夹下。

图 6-2 在KEIL5中新建工程1.选择CPU型号这个根据你开发板使用的CPU具体的型号来选择， M4至尊版选STM32F429IGT型号。

如果这里没有出现你想要的CPU型号，或者一个型号都没有，那么肯定是你的KEIL5没有添加device库，KEIL5不像KEIL4那样自带了很多MCU的型号，KEIL5需要自己添加，关于如何添加请参考《如何安装KEIL5》这一章。

图 6-3 选择具体的CPU型号2.在线添加库文件用寄存器控制STM32时我们不需要在线添加库文件，这里我们点击关掉。

图 6-4 库文件管理3.添加文件在新建的工程中添加文件，文件从本地建好的工程文件夹下获取，双击组文件夹就会出现添加文件的路径，然后选择文件即可。

图 6-5 如何在工程中添加文件4.配置魔术棒选项卡这一步的配置工作很重要，很多人串口用不了printf函数，编译有问题，下载有问题，都是这个步骤的配置出了错。

STM32F429开发套件入门指南

STM32F429开发套件入门指南首先，我们需要准备以下材料：1.STM32F429开发套件B数据线3.计算机接下来，我们将按照以下步骤进行设置和配置：1. 连接STM32F429开发套件与计算机，使用USB数据线将开发板的Micro USB端口连接到计算机的USB端口。

3. 打开STM32CubeMX软件，并选择“New Project”创建一个新的项目。

4.在弹出窗口中输入项目的名称，并选择你的开发板型号，这里选择STM32F429ZIT65. 点击“Pinout & Configuration”选项卡，在右侧窗口中配置GPIO引脚、时钟源和外设。

6.配置GPIO引脚：根据你的需求选择对应的引脚功能（如输入、输出、复用等）。

7.配置时钟源：选择适合你的应用的时钟频率，可以使用默认配置。

8. 配置外设：在“Configuration”选项卡中选择需要使用的外设（如 USART、SPI、I2C等），并根据需求进行配置。

9. 点击“Project”选项卡，在右侧窗口中选择你的编译器（如Keil MDK、IAR等）和你希望生成的项目类型（如C工程、C++工程等）。

11. 在生成的代码中，我们可以找到一个名为“main.c”的文件，这是我们编写和修改代码的主要文件。

12.打开生成的项目代码，根据需求编写和修改代码。

13.使用你选择的编译器编译和调试项目。

14. 烧录程序：在生成的项目代码目录中，找到一个名为“xx-firmware.bin”的文件，这是我们需要烧录到开发板上的二进制固件文件。

15. 使用烧录工具（如ST-LINK/V2或J-Link）将二进制固件文件烧录到开发板上。

16.断开开发板与计算机的连接，在开发板上通过使用外设（如按键、LED等）进行功能测试。
