用硬件协议栈芯片w3100a实现udp协议，用51单片机实现 kei51环境

这是一个用于实现电脑和pic单片机通讯的，通过usb接口的通讯程序！第二部分-This is a pic for the realization of single-chip computer and communications through the usb interface of the communication process! Part II

avrm16控制ds18b20的使用，使用avrstudio进行编译-DS18B20 use avrm16 control, the use of avrstudio compile

用51汇编语言设计的DTMF发生器程序 输出到PI的每次间隔是52个指令周期 主频：6M，6M/12=0.5M,每个指令周期：2uS 即每次输出到P1的时间间隔是122uS 指令周期数：52 + 9 = 61-51 assembly language using the design process DTMF generator output to the PI for each interval is 52 instruction cycle speeds : 6M, 6M/12 = for 0.5 per instruction cycle : 2uS that each output to the P1 time interval is 122uS instruction cycle : 52 9 = 61

PC 通过串口工具在发送节点A 端输入想要发送的数据，点击发送，在接收节点B 端 PC 上的串口工具上，可以看到节点B 收到的内容。如要发送10 个字节内容为11 22 33 44 55 66 77 88 99 AA 的数据/时，在发送节点A 端的串口工具上输入 0A 11 22 33 44 55 66 77 88 99AA，其中0A 代表要发送数据的长度，以16 进制表示。在接收节点B 端的串口工具上就可以收到相应的数据。-PC through the serial port tool sending node A wants to send data from client input, click on send, at the receiving node B-side on a PC serial port tools, you can see the node B received. If you want to send 10 bytes of content 11 22 33 44 55 66 77 88 99 AA of the data/pm at the sending node A on the input side of serial port tools 0A 11 22 33 44 55 66 77 88 99AA, in which you want to send on behalf 0A the data length to 16 hexadecimal said. Node B at the receiving end of the tool on the serial port can receive the corresponding data.

最近作的AD9852的FM扫频模式，自动计算频率，采用单片机的总线访问方式，非常方便，你要做 的就是填数-Recently, the AD9852 for the FM sweep mode, automatic calculation of the frequency of the use of single-chip bus access method, a very convenient, you have to do is fill in a few
