Description: 串行通信接口标准经过使用和发展，目前已经有几种。但都是在RS-232标准的基础上
经过改进而形成的。所以，以RS-232C为主来讨论。RS-323C 标准是美国EIA(电子工业联合
会）与BELL等公司一起开发的1969 年公布的通信协议。它适合于数据传输速率在0～
20000b/s 范围内的通信。这个标准对串行通信接口的有关问题，如信号线功能、电器特性
都作了明确规定。由于通行设备厂商都生产与RS-232C制式兼容的通信设备，因此，它作为
一种标准，目前已在微机通信接口中广泛采用。-Serial communication interface standards through the use and development, now has several. But they are in the RS-232 standard on the basis of improved formed. Therefore, in RS-232C-based discussion. RS-323C standard U.S. EIA (Electronic Industries Association) BELL companies announced in 1969 with the development of communication protocols. It is suitable for the communication data transfer rate in the 0 ~ 20000b/s range. The standard serial communication interface of the relevant issues, such as the signal line function, electrical characteristics have been clearly defined. Since access equipment manufacturers are producing compatible with standard RS-232C communications equipment, so it as a standard, has been widely used in computer communication interface.

Description: RS-232、RS-485和S-422的区别
1、RS-232-C
RS-232-C是美国电子工业协会EIA（Electronic Industry Association）制定的一种串行物理接口标准。RS是英文“推荐标准”的缩写，232为标识号，C表示修改次数。RS-232-C总线标准设有25条信号线，包括一个主通道和一个辅助通道。 -RS-232, RS-485 and RS-422 difference 1, RS-232-C RS-232-C serial physical interface is a standard Electronic Industries Association EIA (Electronic Industry Association) to develop. RS is in English "recommended standard" abbreviation for the identification number 232, C represents the number of changes. RS-232-C bus standard has 25 signal lines, including a main channel and a secondary channel.

Description: 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,
