单片机控制led滚动屏(可扩展)
应用背景使用c8051f020单片机做主机,控制led屏显示芯片带动led发光二级管,使用扫描方式可显示文字 字母等,关键技术由于c8051f020单片机的频率高,做主控制器可做到led亮度可调,无闪烁,稳定性好。本程序是32x24点阵的led模块,可以扩展。

HART协议由Rosemount公司也开
HART协议由Rosemount公司开发且已向每个使用者开放HART协议采用标准的Bell 202频移键控信号以1200波特通信以低电平加载于4mA~20mA模拟信号上,由于载波信号的平均值为零所以它对模拟信号没有影响。-HART agreement develops by Rosemount Corporation also opened
the HART agreement to each user to use the standard the Bell 202
frequency-shift keying signal increase by 1,200 bauds correspondences
by the low level on the 4mA~20mA simulated signal, because
intelligence signal mean value for zero therefore it has not affected
to the simulated signal.
