S32K1xx Series Reference Manual 用户手册--2029页 Supports S32K116, S32K118, S32K142, S32K144, S32K146, and S32K148S32K是一款符合AEC-Q100规范、基于32位ARM Cortex-M4F和Cortex-M0+内核的MCU，适用于通用汽车和高可靠性工业应用。The S32K1xx product series further extends the highly scalable portfolio of Arm® Cortex®-M0+/M4F MCUs in the automotive industry. It builds on the legacy of the KEA series, while introducing higher memory options alongside a richer peripheral set extending capability into a variety of automotive applications. With a 2.70–5.5 V supply and focus on automotive environment robustness, the S32K product series devices are well suited to a wide range of applications in electrically harsh environments, and are optimized for cost-sensitive applications offering low pin-count options. The S32K product series offers a broad range of memory, peripherals, and package options. It shares common peripherals and pin counts, allowing developers to migrate easily within an MCU family or among the MCU families to take advantage of more memory or feature integration. This scalability allows developers to use the S32K product series as the standard for their end product platforms, maximizing hardware and software reuse and reducing time to market

如果在调谐器或电视机附近使用本机或任何其他使用微处理器的电子设备，则可能会产生图像的噪声或干扰。如果发生这种情况，请采取以下步骤将本机安装在尽可能远离调谐器或T的地方。远离调谐器或T，远离本机的电源线和输入/输出连接电缆。尤其在使用室内天线或300欧姆馈线。我们建议使用室外天线和75 Q / ohm同轴电缆Noise or disturbance of the picture may be generated if this unit or any other electronic equipment using microprocessors is used near a tuner or TV If this happens, take the following stepsInstall this unit as far away as possible from the tuner or T Run the antenna wires from the tuner or T away from this unit ' s power supply cord and input/output connection cables. Noise or disturbance tends to occur particularly when using indoor antennas or300 ohm feeder wires. We recommend using outdoor antennas and 75 Q/ohm coaxial cables

随着科技的发展，人们在日常生活中使用的电器越来越多，电子设备的电磁兼容性（EMC）也越来越重要。所以，人们对电子设备的电磁兼容性的要求也越来越严格，越来越规范。而在市场竞争中，如何降低成本、减少设备体积，是各电子设备制造厂家重点研究的课题。通过对开关电源的EMI滤波电路的类别和相应的技术特点进行分析，设计出一种既能提高性能，又能降低成本的滤波电路。With the development of technology, appliances people use in their daily lives, more and more electronic devices electromagnetic compatibility （ EMC ） has become increasingly important. So, people electromagnetic compatibility requirements of electronic devices have become increasingly stringent, more and more standardized. The competition in the market, how to reduce costs, reduce equipment size, is the subject of the electronic equipment manufacturer focused on research. Through the technical characteristics of the respective category and the EMI filter circuit switching power supply is analyzed both designed to improve a performance of the filter circuit can reduce the cost.

该步进电机驱动器又称为EasyDriver，EasyDriver能够为两级步进电机提供大约每相750mA（两极一共1.5A）的驱动。它默认设置为8步细分模式（所以如果你的电机是每圈200步，你使用EasyDriver时默认为每圈1600步），更多细分模式可以通过将MS1或MS2两个接脚接地进行设置。这是一种基于Allegro A3967驱动芯片的细分断路器。对于此设计的完整规格，请查阅A3967的参数表。它的最大每相电流从150mA到750mA。可以采用的最大驱动电压大概是30V，其中包括板载5V的调压器，所以只需要一个电源。质优价廉，这玩意儿只要十几美元，比你自己制作电路板更便宜。步进电机驱动器设计特色：· A3967 Microstepping Driver· MS1 and MS2 pins broken out to change microstepping resolution to full, half, quarter and eighth steps (defaults to eighth)· Compatible with 4, 6, and 8 wire stepper motors of any voltage· Adjustable current control from 150mA/phase to 700mA/phase· Power supply range from 6V to 30V. The higher the voltage, the higher the torque at high speeds

ATS2819/ATS2819P标准应用方案主要分为以下功能模块：Power supply，BlueTooth，Audio Input/Output（包括codec、I2C、SPDIF），FM Receiver，disaplay（LED&LCD），USB，SPI NOR Flash Memory，SD/MMC/MS Card等。1.2原理图设计总体原则1原理图设计需要按照方案规格的要求实现各项硬件功能，尽量避免功能模块相互间的资源冲突。如果存在I/O复用，接收复用等情况，除了需注意检查I/O上电状态，接口时序等，还需要注意复用的SIO工作频率与工作电压域是否符合要求(如WIO)，确保功能设计正确实现。2原理图设计要求性能达到要求。如稳定性，启动电压，功耗，ESD，EMI等。要注意检查模块电源开关状态，选择的原件标称及精度、材质，接口保护元件和EMI滤波器等。3系统时钟26MHZ，要求CL为7~9PF，精度为+-10PPM。这样才能保证系统能正常工作。4当设计PCB受限于模具大小时，各个模块无法保证均能得到最优的布局布线(如滤波电容要求靠近IC、走线上要求尽量少的过孔与尽可能短的走线)。因为在此给出一个模块优先级以供设计人员参考，从而提高方案设计的效率，增加一版work的可行性。将优先级以阿拉伯数据排列
