我需要通过串行3线接口设置CYI5SM1300 AB寄存器;
我发现了一些串行串行接口的信息,没有接口定时; 我在哪里可以买到呢? 我找不到对内部寄存器的价值。 另一个问题是,引脚4的描述(SyDATA),它是一个数字输入/输出,所以可以通过串行3线接口读取寄存器值,以及如何实现它。 谢谢,请帮帮我! 丹尼斯。 以上来自于百度翻译 以下为原文 I need to set the register of CYII5SM1300AB through Serial 3-Wire Interface; I have find a few infomation of the serial 3-wire interface, and there is not the interface timing; Where can i get it. And i can't find how to load the value to the interal register. Another question, the description of Pin 4( S_DATA), it's an digital input/output, so can i read the register value through the serial 3-wire interface, and how to realize it. Thanks and please help me! Dennis. |

串行接口是3线SPI接口,该设备工作在半双工模式,这样您也可以读取数据。主时钟操作应达到40MHz。
似乎没有一个确切的描述与接口定时或应用笔记相对于图像传感器你有问题。赛普拉斯具有SPI接口工作,通过PSOC器件的各种实例演示。您可以在其中找到一般的接口时序。关于SPI的几个链接,可以检查更多信息如下: HTTP://www. CyPress?COM/?DOCSID=27209——PSOC软件中的SPI组件数据表。 HTTP://www. CyPress?COM/?RID=34609 AN51234 PSOC®1 PSOC基础- SPI用户模块HTTP://wwwyCysP.COM/?RID=48908 -串行外设接口(SPI)从机2.10 我希望这能帮助你继续前进。 以上来自于百度翻译 以下为原文 The Serial interface is 3-wire SPI interface having the device work in half duplex mode so you can read the data as well. The master clock operation should be upto 40MHz. There does not seem to be an exact description with the interface timing or an application note with respect to the Image Sensor you have in question. Cypress has SPI interface working demonstrated through various examples using the PSoC Device. You can find the general interface timing in them. A few links on SPI that can be checked for more information are as follows: http://www.cypress.com/?docID=27209 – SPI Component Datasheet in the PSoC software. http://www.cypress.com/?rID=34609 - AN51234 - PSoC® 1 - PSoC Fundamentals - SPI User Module http://www.cypress.com/?rID=48908 - Serial Peripheral Interface (SPI) Slave 2.10 I hope this helps you to proceed further. |

谢谢你的回复!
你知道,我有SPI接口的一些信息,但有4线SPI,并将数据通过MOSI和MISO转移,而只有一个线在cyii5sm1300ab 3线接口,所以我不知道如何从传感器数据传输。 我有数据表(启C)的传感器,有界面的一些信息,但这是不够的writingprogrammeto驱动接口。 如果有更多的信息,请告诉我! 谢谢你的回复! 以上来自于百度翻译 以下为原文 Thanks for you reply! You know, i have got some information of SPI interface, but there are four wires for the SPI, and the data is transfered through MOSI and MISO, while there are only one wire of the 3-wire interface in the CYII5SM1300AB, so i have no idea how to transfer the data from the sensor. And i have got the datasheet(Rev.C) of the sensor, there are some information of the interface, but it's not enough for writing programme to driver the interface. If there are some more information, please tell me! Thanks your kind reply! |
