1.由上位机发送1给单片机时,蜂鸣器以400ms频率发声,发2时以200ms频率发声,发3时以100ms频率发声,发4时关闲蜂鸣器。
1.以2400bps从计算机发送任一字节数据,当单片机收到该数据后,在此数据前加上一序号然后连同此数据一起发送至计算机,当序号超过255时归零。
2.以16进制发送一个0-65536之间的任一数,当单片机收到后在数码管上动态显示出来,波特率自定。
3. 用AD以1HZ的频率采集模拟信号,然后转换成数字量,再将其以1200bps发送到计算机,在计算机上显示。
4.按下矩阵键盘第一行时以1200bps发送,1,2,3,4,第二行时以2400bps发送5,6,7,8,第三行以4800bps发送,9,10,11,12,第四行以9600pbs 发送,13,14,15,16.
(1. From the PC to send a single chip, the buzzer to 400ms frequency of sound, made 2 to 200ms frequency sound, made from 3 to 100ms frequency sound, made 4 free buzzer off.
1. To 2400bps from the computer to send any byte of data, when the microcontroller receives the data in this data with a serial number before then sent along with the data to the computer, the serial numbers when more than 255 zero.
2. To send a 16-hexadecimal any number between 0-65536, when the microcontroller in the digital receipt is displayed on a dynamic, custom baud rate.
3. 1HZ with the frequency of AD in order to capture analog signals, then converted to digital, and then send it to 1200bps to the computer, the computer display.
4. Press to 1200bps matrix keyboard to send the first row, 1,2,3,4, 5,6,7,8 the second row to 2400bps send the third line to 4800bps send, 9,10,11,12 , the fourth line to 9600pbs send, 13,14,15,16.

UART_TXaRX
单片机接收从电脑串口发送出来的一串字符串,却只能接收到第一个字符,其他的都丢失了或者是接收到的是乱码,却不知道是什么原因。其实,那是因为,虽然单片机的是全双工串口,但是串口的缓冲区(SBUF)却一般只有一个字节,即1Byte,远没有像电脑串口的缓冲区以KB计算那么大,并且,单片机的处理速度是很有限的,试想一下,假如要求一串字符串以9600bps的速率,一个起始位,一个结束位,无校正位,相当于960Byte/s传输到单片机,单片机要是能够全部接收的话,那么单片机接收和处理一个字节的时间仅为约1ms的时间。这说明了,如果单片机的处理速度不够快,还没有将接收到的上一帧数据及时转送到单片机的RAM中,而电脑串口又传输过来一帧新的数据,这帧新的数据就会把单片机的串口输入缓冲区的SBUF给刷新掉,或者说单片机压根就没有接收到新的一帧数据,造成了数据的丢失或接收到乱码。
如果需要单片机接收到从串口发送过来的一段很长的字符串,并且能够都正常接收和显示(TX&RX FUNCATION between PC and MCU)
