说明：  rtl8370单芯片8口千兆交换机原理图(Rtl8370 single chip 8 gigabit switch schematic diagram)

基于74系列数字芯片的8层电梯控制器，Multisim13仿真(An 8- layer elevator controller based on 74 series digital circuit chip.)

说明：  对delta sigma进行设计，实现delta sigma ADC的设计(this is use for delta sigma adc ,and design and achieve adc)

制作电子负载，恒压、恒流、恒阻的情况。有原理图、PCB板，可以参考一下。(Make electronic load, constant pressure, constant current, constant resistance. There is a schematic diagram, PCB board, can be referred to.)

全志A33芯片资料，包括芯片手册，用户使用说明等等(Quanzhi A33 Chip Data)

资源描述spi 测试接口，用来读写寄存器，经过实际测试，可以正确读写。

原理采用Altium Designer软件设计，内含MPPT的BUCK拓扑结构、DCDC复制电源转换、微控制器等电路(The principle is designed by Altium Designer software, including MPPT BUCK topology, DCDC copy power conversion, micro controller and so on)

说明：  通过arduino mega2560驱动2步进电机 以及附加配件如显示器蓝牙等(Drive 2-step motor and additional accessories such as display Bluetooth through Arduino mega2560)

用于驱动2.13英寸的墨水屏，电纸屏。包含arduino、STM32平台的源码。(Used to drive an ink screen of 2.13 inches, an electric paper screen. Contains Arduino, STM32 platform source code.)

说明：  基于51/52单片机 1，探测环境温度，以LCD1602 做显示单元 2，可设置上限/下限数值，从而做到警报的提醒及应急设施的启动 3，超过设置限值时，会启动 LED 、蜂鸣器以及电机（仿真时使用）应用可使用其他代替(Based on 51 / 52 single chip microcomputer 1. Detect the ambient temperature with LCD1602 as the display unit 2. The upper / lower limit value can be set to remind the alarm and start the emergency facilities 3. When the setting limit is exceeded, the LED, buzzer and motor (used in simulation) application will be started, and other alternatives can be used)
