C8051F060 自带高速AD进行数据采集 可达100兆采样率 并切缓存与片外ram 并把采集数据通过串口发送给PC ( Data Acquisition example for C8051F060 Description: This example illustrates the use of ADC1 and the DMA to acquire and store data. It is intended for use with the C8051F060 target board in the development kit. // This code measures a signal at the AIN0 input with the 16-bit SAR ADC0. // The data is sampled at a rate of 100kHz. ADC output data is transferred to XDATA memory space using the DMA. // // With the EMIF configured for off-chip XRAM access (on the upper ports), this code moves the ADC data to the C8051F060TB target boards s SRAM device. // Once data acquisition is complete, the code then prompts the user to press the P3.7 // button on the target board when ready to receive the data via the UART0 serial port. The TB features an RS-232 transceiver and connector, so the data can be transferred // to a PC via its serial port. // The code is set to acquire up to 32768 samples (for 64kbytes of data). The SRAM device - can accommodate up to 128kbytes, )

多机通信，设计了一种基于MCS－51系列单片机AT89S52 的多机通信系统。当1号机与2号机通信时，1号单片机为主机，2号机为从机。主机通过串口向从单片机发送指定格式的数据，从单片机收数据并作出响应，从机通过LED数码管显示通信状态。1号单片机通过矩阵键盘控制通信过程与显示。这通信模式是主从模式，只能是主机发信息给从机。当1号机与3号机通信时，不存在主从机之分，是平权模式。1号机可以通过按键发信息给3号机，3号机也可以通过按键发信息给1号机，通过各自的数码管显示通信数据，LED灯显示通信状态。(Multi-machine communication, design a multi-machine communication system based on MCS-51 series single-chip AT89S52' s. When the 1st and the 2nd machine-machine communication, the 1st microcontroller host, the 2nd machine as a slave. Data sent to the host computer through the serial port specified format from SCM, SCM and respond to the received data from the slave via LED digital display communication status. 1 MCU control the communication process through the matrix keyboard and display. This mode of communication is a master-slave mode, the host can only send a message to the slave. When the 1st and the 3rd machine-machine communication, there is no slave master points, is affirmative mode. The 1st machine can send a message to the 3rd through the key machine, the 3rd machine can also send information via the button to the 1st machine, display data communication through their digital tube, LED lights display the communication status.)
