1。自恢复自发站立
1.单机自发自收串行通信。接收键入字符,从8251A的发送端发送,与同一个8251A的接收端接收,然后在屏幕上显示出来。
2.双机串行通信,在一台PC机键入字符,从8251A的发送端发送给另一台PC机,另一台PC机的 8251A的接收端接收,然后在屏幕上显示出来。
-1. Since the resumption of spontaneous stand-alone serial communication. Type the characters receive from the sending end to send the 8251A, 8251A with the receiving end of a receiver, and then displayed on the screen. 2. Dual serial communication, in a PC-type characters, from the sending end 8251A sent to another PC, another PC-8251A to receive the receiving end, and then displayed on the screen.

采集AIN0和AIN1的信号,通过可调电阻,使输入的模拟信号发生改变,来进行A/D转换。为保证数据的准确性,通常采集10次以上,在求平均值。A/D转换器采集AIN0和AIN1的信号,并显示出来。-AIN1 acquisition and AIN0 signal, through an adjustable resistor, so that the analog signal input to change, to carry out A/D conversion. In order to ensure the accuracy of the data is usually collected 10 times more than the average in the order. A/D converter and acquisition AIN0 signals AIN1 and displayed.
