Description: 使用 SN8P1702A 的低成本上下限通用数字表头
图示电路是一款输入电压 DC200mV ,满度读数 2000 个字的数字电压表头电路.分辨力达到 100uV/字 .这种参数与通常使用的 3 位半数字表头相吻合,(但是这里没有负电压信号的测量功能).因此,可以方便地在无需负信号输入的场合替换原来的数字表头.
替换带来的好处是这里具有上下限设置的控制功能,而普通的 3 位半数字表头却只能测量显示而不能进行设置控制.
配原理图应用和连接说明:
图A:测量和控制直流 200mA 信号.如果是交流信号,需要先有 AC-DC 转换.
图B:测量和控制直流 200mV 信号.如果是交流信号,需要先有 AC-DC 转换
图C:测量和控制直流 4～20mA 信号.这种信号可以远传,例如压力传感器的输出.输入配置的 -50mV 电压是在输入 4mA 的时候,恰好抵消取样电阻上的压降而设.实际中需要使用低内阻的恒压源.
图D:测量和控制温度测量信号.LM35D 具有 10mV/℃ 的输出,因此,通过 10:1 的分压,达到 1mV/℃,100℃ 就是 100mV,100mV 就显示 1000 个字,把小数点定位在十位上,就是 100.0℃
附有 AD 转换部分的源程序-Use SN8P1702A low-cost universal digital meter on the lower
Icon is a circuit input voltage DC200mV, full-scale reading of 2000 characters digital voltage meter circuit. Resolution to 100uV/word. This argument often used three and a half number of the header match, (but there is no negative voltage signal measurement function). Thus, it can easily without a negative signal input the number of occasions replace the original header.
The benefits are here to replace a set of control functions on the lower limit, while the ordinary three half-meter can only measure the number of display and control can not be set.
Schematic connection with the application and instructions:
Figure A: 200mA DC measurement and control signals. If the AC signal, you need to have AC-DC conversion.
Figure B: 200mV dc measurement and control signals. If the AC signal, you need to have AC-DC converter
Figure C: measurement and control of DC 4 ~ 20mA signal. This signal can be remote, such as pressure s Platform: |

Description: 随着社会的进步和经济的快速发展，在现代生活中，彩灯作为一种景观照明应用越来越多。彩灯控制器，大家定不陌生，现代城市的一大特色就是各种色彩的灯光，不管发光的元件是什么，它们都离不开彩灯控制，通过设计一款通用型高性能的彩灯控制系统，实现多种彩灯模式功能。
选用ws2812 led 控制芯片，使用STM32设计主控器，实现对8×8或16×16盏led彩灯的控制，主控器通过编程实现可以通过按键或遥控方式进行彩灯模式选择，可实现多种单彩色、混合彩色、闪烁、流水、呼吸、特殊形状等模式。-With the progress of society and the rapid development of economy, in modern life, as a kind of landscape lighting, colorful lights are used more and more. Lantern controller, everyone is familiar with, a major feature of modern city is the variety of colors of light, no matter what the luminous element is, they cannot do without lights control, the control system through the design of a universal high-performance lantern, lantern mode to achieve a variety of functions.
Using ws2812 LED control chip, using the STM32 design of main controller, to achieve control of the 8 x 8 or 16 x 16 LED lights, the main controller can be realized by programming by pressing a button or remote control of lights mode selection, can achieve a variety of single color, mixed color, flicker, water, breathing, special shape model.
