communication-circuit
- 由于RS232的电平与Arduino Mega 2560的接口电平不能兼容，所以就需要进行电平的转换，即进行串口转换模块的设计，本文选择利用ATMEGA16U2-MU模块来做电平转换，将上位机的指令通过此模块发给下位机-Since the RS232 level is not compatible with the Arduino Mega 2560 interface level, so we need to level conversion, that is designed to seri
ADSTAR-L_STK-V1.1
- ADSTART原理图，驱动TFT液晶显示屏，动画演示，电子相册等。-ADSTART schematic, drive TFT LCD screen, animation, electronic albums and so on.
DatasheetPforP3SP-SO2-20
- Data Sheet for SO, SO2 sensors
SG-MPPT-HL-K-V1
- 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)
Responders
- 本设计为多路智能抢答器，所以这种抢答器要求有不同组别的抢答输入信号，并能识别最先抢答的信号，直观地通过数显和蜂鸣等方式显示出组别；对回答问题所用的时间进行计时、显示、超时报警、预置答题时间，同时该系统还应有复位、倒计时启动功能。(This design is multi-channel intelligent responder, so this responder requires different groups of rush answer input signal, and can id
ST-Link V2
- STM32的JTAG / SWD接口是通过20PIN连接线连接目标板，所以ST-LINK/V2连接至STM32目标板时需要注意连接方向(The JTAG / SWD interface of STM32 connects the target board through the 20PIN connection line, so the connection direction needs to be noticed when ST-LINK/V2 is connected to the STM
dpll源程序
- 一种设计数字锁相环的思路，包含异或鉴相器、k模可逆计数器、脉冲加减计数器、N分频器等，实现相位的锁定。(A design of digital phase locked loop (PLL) consists of a phase discriminator, a K mode reversible counter, a pulse addition and subtraction counter, a N frequency divider and so on, to lock the pha
DS_N76E003中文规格书_SC_Rev1.00
- 随着STM8的停产,新唐的N76E003 pin对pin替换STM8S003F3P6,而且很便宜,故这个时候拿来替换使用再好不过。(With the discontinuation of STM8, N76E003 pin of Xintang replaced STM8S003F3P6 with pin, which was very cheap, so it would be a good time to replace it.)
