电源电路如图2所示，电路中，引脚6的VBAT为电池，引脚22的VDDA为外部芯片电源，VDD_1~5为外部电源，供给3.3V，VSSA接地。The power supply circuit is shown in Figure 2. In the circuit, VBAT onpin 6 is the battery, VDDA onpin 22 is the external chip power supply, VDD_1~5 is the external power supply, supplying 3.3V, and VSSA is grounded.

电源引脚滤波电路如图3和图4所示。图3中在芯片的电源引脚和地引脚之间连接5个滤波电容，用来滤除电源的毛刺。图4中使用电感来滤除电源中的交流信号，并使用一大一小两个电容来分别滤除电源中的低频噪声和高频噪声。VDDA是经滤波后得到的，VSSA是经滤波后的电感所得到的。减少引线，可增加输入电流大小，Vref为参考电压，电感的作用是通直流阻交流，电容的作用是进行滤波，在参考电压之间增加0.1uF和10uF的滤波电容，其中小电容可以虑高频噪声干扰，大电容可以虑低频噪声干扰。The power supply pin filter circuit is shown in Figure 3 and Figure 4.

外部时钟电路在单片机系统里，晶振的作用很大，它结合单片机内部的电路，产生单片机运行时需要的时钟频率，单片机的一切指令的执行都是建立在这个基础上的，晶振提供的时钟频率越高，那单片机运行的速度就越快。晶振分为有源晶振和无源晶振两种，本系统中使用的是无源晶振，晶振时钟电路如图5所示。本系统使用的是无源晶振是25MHz的晶振，外加两个电容，大小为20pF，电容大小由芯片手册中指定，输入信号经OSC IN进入，经X1无源晶振，最后输出的信号依然为25MHz，由此产生反馈。External clock circuit In the single-chip microcomputer system, the crystal oscillator plays a very important role. It combines the internal circuit of the single-chip microcomputer to generate the clock frequency required for the operation of the single-chip microcomputer. The execution of all instructions of the single-chip microcomputer is based on this. The clock frequency provided by the crystal oscillator The higher the value, the faster the MCU will run. There are two types of crystal oscillators: active crystal oscillator and passive crystal oscillator. The passive crystal oscillator is used in this system. The crystal oscillator clock circuit is shown in Figure 5. This system uses a passive crystal oscillator, which is a 25MHz crystal oscillator, plus two capacitors with a size of 20pF. The capacitor size is specified in the chip manual. The input signal enters through OSC IN, passes through X1 passive crystal oscillator, and the final output signal is still 25MHz. , resulting in feedback.

复位电路中使用MAX809复位管理芯片，MAX809为低电平复位管理芯片。用于监控微控制器和其他逻辑系统的电源电压。它可以在上电、掉电和节点情况下向微控制器提空复位信号，当电源电压低于预设的门槛电压时，器件会发出复位信号，直到在一段时间内电源电压又恢复到高于门槛电压为止。MAX809有低电平有效的复位输出，典型值是17uA的低电源电流使MAX809能理想的用于便携式、电池供电的设备。它使用3管脚的SOT23封装。The MAX809 reset management chip is used in the reset circuit, and the MAX809 is a low-level reset management chip. Used to monitor supply voltages for microcontrollers and other logic systems. It can provide a reset signal to the microcontroller under power-on, power-off and node conditions. When the power supply voltage is lower than the preset threshold voltage, the device will issue a reset signal until the power supply voltage returns to high within a period of time. up to the threshold voltage.

复位电路如图6所示。NRST芯片为复位引脚，平常都为高电平，在复位电路中，都会不断监测3号引脚的电压值，当3号引脚的电压值低于2.3V的时候，2号引脚会产生低电平，以此来给主控芯片STM32复位。The reset circuit is shown in Figure 6. The NRST chip is a reset pin, which is usually at a high level. In the reset circuit, the voltage value of the No. 3 pin will be continuously monitored. When the voltage value of the No. 3 pin is lower than 2.3V, the No. 2 pin will be Generate a low level to reset the main control chip STM32.

仿真写入电路如图7所示。仿真写入电路有两种写入方式，分别为JTAG和SWD。JTAG也是一种国际标准测试协议，主要用于芯片内部测试。现在多数的高级器件都支持JTAG协议,如DSP、FPGA器件等。标准的JTAG接口是4线：TMS、TCK、TDI、TDO,分别为模式选择、时钟、数据输入和数据输出线。 相关JTAG引脚的定义为：TCK为测试时钟输入；TDI为测试数据输入，数据通过TDI引脚输入JTAG接口；TDO为测试数据输出，数据通过TDO引脚从JTAG接口输出；TMS为测试模式选择，TMS用来设置JTAG接口处于某种特定的测试模式；TRST为测试复位，输入引脚，低电平有效。The simulation write circuit is shown in Figure 7. There are two writing methods for the simulation writing circuit, namely JTAG and SWD. JTAG is also an international standard test protocol, mainly used for chip internal testing. Now most advanced devices support JTAG protocol, such as DSP, FPGA devices and so on. The standard JTAG interface is 4 lines: TMS, TCK, TDI, TDO, which are mode selection, clock, data input and data output lines respectively. The definition of the relevant JTAG pins is: TCK is the test clock input; TDI is the test data input, and the data is input to the JTAG interface through the TDI pin; TDO is the test data output, and the data is output from the JTAG interface through the TDO pin; TMS is the test mode selection , TMS is used to set the JTAG interface in a specific test mode; TRST is the test reset, input pin, active low.

SWD模式比JTAG在高速模式下面更加可靠。在大数据量的情况下面JTAG下载程序会失败，但是SWD发生的几率会小很多。当GPIO刚好缺一个的时候，可以使用SWD仿真，这种模式支持更少的引脚。当板子体积有限的时候推荐使用SWD模式，它需要的引脚少，当然需要的PCB空间就小了。所以一般用SWD模式更好一些。SWD mode is more reliable than JTAG in high-speed mode. In the case of a large amount of data, the JTAG download program will fail, but the chance of SWD will be much smaller. When the GPIO is just missing one, you can use SWD emulation, which supports fewer pins. It is recommended to use the SWD mode when the board size is limited, it requires fewer pins, and of course requires less PCB space. So it is generally better to use SWD mode.
