Driving proportional valves from microcontroller I am looking to drive a current regulated proportional (solenoid) valve that needs up to 85mA @ 24V from a microcontroller. So far I found this circuit that looks pretty straightforward: What are other…

AN2820 Driving bipolar stepper motors using a medium-density STM32F103xx microcontroller Introduction This application note describes how to achieve compact size, high speed and low cost with less resources when driving bipolar stepper motors using t…

http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1824&appnote=en011794 In many applications, a DC/DC Converter is used to produce a regulated voltage or current, derived from an unregulated power supply, or from a battery. Ex…

http://www.edn.com/design/analog/4337128/Make-a-DAC-with-a-microcontroller-s-PWM-timer Many embedded-microcontroller applications require generation of analog signals. An integrated or stand-alone DAC fills the role. However, you can often use PWM si…

Few microcontrollers include a DAC. Although you can easily find an inexpensive DAC to control from your microcontroller, you can use unused peripherals instead of adding parts. Fortunately, you can convert a microcontroller's ADC channel along with…

There are commonly three types of memories in a PIC Microcontroller, Flash Program Memory, Data Memory (RAM) and EEPROM Data Memory. We write Programs in the Flash Program Memory of a microcontroller. Flash memory makes it possible to program a micro…

今天看到一篇关于检测的论文<SqueezeDet: Unified, Small, Low Power Fully Convolutional Neural Networks for Real-Time Object Detection for Autonomous Driving>,论文中的效果还不错,后来查了一下,有一个Tensorflow版本的实现,因此在自己的机器上配置了Tensorflow的环境,然后将其给出的demo跑通了,其中遇到了一些小问题,通过查找网络上的资料解决掉了,在这里…

https://zh.wikipedia.org/wiki/单片机 单片机,全称单片微型计算机(英语:single-chip microcomputer),又称微控制器(microcontroller),是把中央处理器.存储器.定时/计数器(timer/counter).各种输入输出接口等都集成在一块集成电路芯片上的微型计算机.与应用在个人电脑中的通用型微处理器相比,它更强调自供应(不用外接硬件)和节约成本.它的最大优点是体积小,可放在仪表内部,但存储量小,输入输出接口简单,功能较低.由于其发展…
