STM32F103 RS485 DMA方式接收再发送不定长数据，起始和末尾不会有多余数据产生(STM32F103 RS485 DMA transfer and receive variable length data)

可驱动8/16位数码管显示或64/128只独立LED 的芯片BC72811A中断编程。BC7281A只占用单片机3个I/O口(can drive 8/16 Digital Display or 64/128 only independent LED chip BC72811A interrupted programming. BC7281A only occupies three microcontroller I/O port)

一套三相逆变器的原理图和PCB板，控制芯片为HT3117，(A three-phase inverter schematic and PCB board, controller chips for HT3117,)

说明：  使用定时器TIM3输出四路的SPWM波，其中一二路、三四路波形一致，一二路与三四路波形相差180°(Timer TIM3 is used to output four SPWM waveforms, of which one, two, three and four waveforms are identical, and one, two and three and four waveforms are 180 degrees different.)

说明：  采用stm32f4核心板，实现AD采集，效果很理想，可测量流量，液位(Achieving Flow Acquisition)

stm32103RB资料(参考代码)标准例程，包括源代码和pdf解析，有灯，按键，终端，PWM，显示屏，adc，iic，spi，flash，usb等等56个实验例程(Stm32103RB data (reference code) standard routines, including source code and PDF parsing, with lights, keys, terminals, PWM, display, ADC, IIC, SPI, flash, USB and so on 56 experimental routines)

LABjs 的核心是 LAB（Loading and Blocking）：Loading 指异步并行加载，Blocking 是指同步等待执行。LABjs 通过优雅的语法（script 和 wait）实现了这两大特性，核心价值是性能优化。LABjs 是一个文件加载器。(LABjs lets you load pretty much any script file, whether you control it or not, with no intrusion or convention for dependencies, other than the order and blocking that you define. It keeps track of what you ve asked for and what has downloaded, and lets you only define a handler once for a group of scripts that will execute together in parallel. The API style (with chaining) makes is very easy to convert a set of script tags in your page into code to load them, without having to worry that race conditions will cause issues for scripts loading in the wrong order if there are explicit dependencies involved.)
