Description: USB、串口、并口是PC机和外设进行通讯的常用接口，但对于数据量大的图像来说，若利用串行RS-232协议进行数据采集，速度不能达到图像数据采集所需的要求；而用USB进行数据采集，虽能满足所需速度，但要求外设必须支持USB协议，而USB协议与常用工程软件的接口还不普及，给使用带来困难。有些用户为了利用标准并行口(SPP)进行数据采集，但SPP协议的150kb/s传输率对于图像数据采集，同样显得太低。因此,为了采集数据量大的图像数据,本文采用了具有较高传输速率的增强型并行口协议(EPP)和FPGA，实现对OV7620CMOS图像传感器进行高速数据采集，它最高速率可以达到2Mb/s。-USB, serial port, parallel port is PC and peripherals used for the communication interface, But for the large volume of data images, if the use of Serial RS-232 data acquisition agreement, speed image data can not achieve the requirements for acquisition; using USB for data collection, can meet the required speed, But requirements must support USB peripherals agreement, and USB agreement with the commonly used engineering software interface is not universal, difficult to use. Some users to take advantage of standard parallel port (SPP), for data collection, But SPP agreement of 150 kb / s transfer rate for image data acquisition, the same is too low. Therefore, in order to collect large quantities of data image data, In this paper, the high transmission rate of enhanced parallel port proto Platform: |

Description: 随着对传输速率要求的日益提高，越来越多的设备都支持并口通讯。目前可用的并口调试工具并不多，而且支持的模式非常有限。为了方便软件和硬件工程师对并口进行调试，开发了该调试工具。该工具支持SPP、ECP、EPP模式的调试。 -With the increasing transmission rate requirements, more and more devices support parallel port communication. Currently available parallel debugging tools are not many, and the support of the model is very limited. In order to facilitate software and hardware engineers to parallel debugging, development of the debugging tools. The tool supports SPP, ECP, EPP mode debugging. Platform: |

Description: 基于CSR官方sink例程修改增加SPP，亲测可用，但是CSR8670开发半开源的，所以烧录程时要配合Sink Configuration Tool和PSTool进行相应配置烧录才能实现SPP双向通讯。(The official CSR sink SPP based on routine modification increases, pro test is available, but the development of CSR8670 semi open source, so the burning process with Sink Configuration Tool and PSTool SPP to achieve the corresponding configuration of burning two-way communication.)
