基于STM32直接操作寄存器版本，07年开关电源控制程序，采集反馈的电压进行PI调节，达到稳压目的。(Register version based on the STM32 direct operation, 07 switching power supply control procedures, collect feedback PI regulating voltage, voltage regulator.)

说明：  点阵显示原代码，上传的为c语言，也有原理图。(Dot matrix display of the original code, upload the c language, but also schematic.)

逻辑分析仪，相位和频率分析，可以实现对喜欢冒险分析，频率范围的问题，使用MSP430微控制器(Logic analyzer, phase, and frequency analysis can be achieved on issues like adventure analysis, frequency range, using the MSP430 microcontroller)

说明：  软件模拟解码PT2262(晶体:12MHZ)(simulation software decoder PT2262 (Crystal : 12MHZ))

TM1652 是一款LED（发光二极管、数码管、点阵屏）驱动控制专用芯片，内部集成了数字通讯电路、 解码电路、数据锁存器、震荡器、LED驱动电路。通讯方式采用异步串口通信（UART）协议，因芯片只 接收单片机发来的数据，仅需要单片机的一个TX端口发送数据给芯片即可，实现单线通讯；在显示驱动 方面，芯片采用动态扫描方式，两种显示模式可选，8级段驱动电流可调，16级位占空比可调；TM1652 内置消隐处理优化电路。(TM1652 is an LED (light-emitting diode, LED, dot-matrix screen) driver control ASIC, integrated digital communications circuits, Decoding circuit, data latch, oscillator, LED driver circuit. Communication using asynchronous serial communication (UART) protocol, because the chip only MCU receives data sent only need a microcontroller TX port to send data to the chip can achieve single-wire communication the display driver Aspects, chip dynamic scan mode, two display modes, 8 segment drive current is adjustable, 16-bit adjustable duty cycle TM1652 Built-in blanking processing optimization circuit.)

说明：  本实验将实现如下功能：开机的时候先检测SD卡和SPI FLASH是否存在，如果存在则获取其容量，并显示在LCD上面（如果不存在，则报错）。之后开始USB配置，在配置成功之后就可以在电脑上发现两个可移动磁盘。我们用DS1来指示USB正在读写，并在液晶上显示出来，同样，我们还是用DS0来指示程序正在运行。(This experiment will achieve the following functions: when booting, first detect the existence of SD card and SPI FLASH, and if there is, obtain its capacity, and display it on the LCD (if not, report an error). Then the USB configuration is started, and after the configuration is successful, two removable disks can be found on the computer. We use DS1 to indicate that the USB is reading and writing, and display it on the LCD. Similarly, we use DS0 to indicate that the program is running.)
