基于ATMEGA16L-8PI单片机的线阵LED图文显示装置
<p>系统由标志杆、16位线阵LED、单片机、电机及调速控制装置、电池、稳压电源等模块组成。以单片机作为主控芯片,通过光敏三极管检测外界光照变化实现自动调节LED亮度显示,采用顶部的独立按键切换,通过C语言进行软件编程,在定位杆和LED装置中的红外对管进行对齐,利用视觉暂留的原理,实现了电机控制LED线阵进行同心圆的顺序和逆序控制,“秒表”显示时间稳定精确,并能清晰显示“TI杯”字符。</p><p
基于单片机温度采集与报警系统的研究
<p>利用DS18B20设计一种多路温度数据采集和直流电机散热系统,可实现语音播报功能。系统主要由单片机电路和一组DS18B20数字传感器构成,同时具有温度显示、数据存储和串行通信模块。通过keil软件编写和调试程序,并利用Proteus仿真测试硬件电路,测温范围-10~+45℃,最后通过LCD1602显示所测温度。将制作实物与温度计置于相同设定温度的场所,研究数据发现单片机温度采集系统更精确。当
分析基于单片机的嵌入式多节点网络通信系统设计
<p>嵌入式系统将传统的人为控制系统转变为机器控制系统,提升了系统的精确性与稳定性,有效地节省了传统模式产生的损耗问题。随着电子技术的不断发展,基于单片机的嵌入式多节点网络通信系统设计逐渐完善。嵌入式系统设计的核心就是单片机,而stm32作为一种32位微控制器,在嵌入式多节点网络通信系统应用中的效果显著。基于此,文章主要对基于单片机的嵌入式多节点网络通信系统设计进行了简单的分析论述。</p><p>
