【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。

更多信息参照ST-LINK/V2in-circuit debugger/programmer for STM8and STM32，该文档描述了ST-LINK/V2所有细节特性。
跳线状态描述CN4都设为ON开发板MCU编程调试CN4都设为OFF外部应用开发板编程调试4.2.1使用ST-LINK/V2编程调试板载STM32F429ZIT6要对板上STM32F429ZIT6编程调试，如图连接2个跳线CN4。
但不要使用CN3连接器，因为可能会干扰MCU通信。
4.2.2使用ST-LINK/V2编程调试其他STM32开发板将ST-LINK/V2用来编程外部STM32系统是很容易的，只需要移除两个CN4上的跳线，并连接你的开发板到CN3接口，如图所示。
注：SB7必须OFF，如果你使用CN2的pin5在你的外部开发板上。

1、5V和3V可以用来作为输出电源，当其他板子连接到P1和P2上时。
在这种状况下，5V和3V引脚提供电源且不能超过100mA。
2、5V和3V也可以用来作为输入电源，这时USB没有连接PC。
在这种状况下，STM32F429Discovery必须使用符合EN-60950-1:2006+A11/2009的电源器件或其他外部设备来供电。
且必须满足安全最低电压要求。
注：板子也可以通过USB用户口上电，被D4和D5二极管保护。
这种情况，5V脚大概为4.4V左右）4.4LED1、LD1COM：LD1预设为红色。

2、LD2PWR红色LED，指示电源。
3、用户LD3连接在PG13I/O上，用户定义。
4、用户LD4连接在PG14I/O上，用户定义。
5、用户LD5当VBUS出现在CN6上，绿灯指示。

通过MicroUSB线连接CN6到一个主设备或从设备，如USB key，鼠标等。
两个LED指示此模块：LD5（绿）指示VBUSLD6（红）指示连接设备过流。
4.7陀螺仪（ST MEMS L3GD20）L3GD20是一个极其紧凑、低功耗、三轴角速度传感器。
它包含一个传感器和一个IC接口（I2C/SPI）。
L3GD20在全范围内可以实现动态的、用户可选（±250dps/500dps/±2000dps），和较强的测量速率。
STM32F429ZIT6通过SPI接口控制这个动作传感器。
4.8TFT LCD开发板支持2.41寸，262K色的LCD。
它采用QVGA（240*320），通过STM32F429ZIT6使用RGB协议来直接驱动。
它包含了ILI9341LCD控制器，可以用2.8±0.3V电平操作。
