功能描述：
|
|
|
此样例演示了USB U盘功能
|
|
|
USB U盘主要是借助 USB MSC 类实现，将MCU的flash划分成两部分，0x08000000~0x08007FFF
|
|
|
作为用户代码区，0x08008000~0x8060000模拟成一个352Kbytes的U盘

|
|
This sample demonstrates the USB Udisk functionality.
|
|
|
USB Udisk is mainly implemented by USB MSC class, the MCU flash is divided into
|
|
|
two region, 0x08000000~0x08007FFF as the user code area, 0x08008000~0x8060000
|
|
|
simulated into a 352Kbytes USB flash drive

测试环境：
|
|
|
测试用板：PY32F403_STK
|
|
|
MDK版本： 5.28
|
|
|
IAR版本： 9.20
|
|
|
GCC版本：GNU Arm Embedded Toolchain 10.3-2021.10
|

Test environment:
|
|
|
Test board: PY32F403_STK
|
|
|
MDK Version: 5.28

|
使用步骤：
|
|
|
1. 下载并运行程序；
|
|
|
2. 通过usb连接线，一端连接STK板，另一端连接PC电脑；
|
|
|
3. PC端显示出一个352Kbytes的U盘，可以在U盘中存储数据
|
|
|
|
|
|
Example execution steps:
|
|
|
1. Download and run the program;
|
|
|
2. Connect the STK board to the PC computer using the USB cable;
|
|
|
3. A 352Kbytes USB Udisk is displayed on the PC. Data can be stored on the
|
|
|
USB Udisk.

|
|
注意事项：
|
|
|
1. 第一次使用时PC端会弹出格式化U盘，请按提示格式化U盘即可。
|
|
|
2. 此样例使用的是384Kbytes flash的MCU，如果要应用到其它尺寸的flash，需要修改代码
|
|
|
3. 此样例中MCU的flash，只预留了32Kbytes给用户程序，如果用户程序超过32KBytes，需
|
|
|
要修改代码
|
|
|
|
|
|
1. When you use the USB flash drive for the first time, format the USB Udisk as
|
|
|
prompted.
|
|
|
2. This example uses the MCU of 384Kbytes flash. If you want to apply other
|
|
|
sizes of flash, you need to modify the code.
|
|
|
3. In this example, the MCU flash reserves only 32Kbytes for the user program.
|
|
|
If the user program exceeds 32KBytes, the code needs to be modified
