怎么通过USB将SPI数据流式传输到PC

你好，亚历克斯，CyCOSOL，CyPrand和Telever是单个事务的测试程序。BulkLoop怎么样？当你需要合适的主机程序时，必须自己制作主机程序。使用CysB.DLL或CYAPI，USB套件3.4.7中有C样本，BulkCurror和CyCurror的CurCE样本。

          Hi Alex, CyConsol, CyControl and Streamer is test program for single transaction. How's BulkLoop? When you need proper Host program, have to make own Host program. That using CyUSB.dll or CyAPi, There are C# samples in USB Suit 3.4.7, Of cource sample of BulkLoop and CyControl.   

谢谢你的回答。BulkLoop也不工作。但这可能是因为我不使用BulkRoad中指定的端点插件。你知道如何改变端点地址吗？我还有一个问题：有没有可能用MATLAB直接读出数据？
非常感谢你的帮助，
亚历克斯

  Thanks for the answer. BulkLoop doesn´t work too. But thats maybe because I dont use the endpoint adresses specified in BulkLoop. Do you know how to change the endpoint adress? 
I have another question:Is there maybe a possibility to read out the data directly by Matlab?
    Thanks a lot for the help,
    Alex

好的，小菜一碟。如您所知，UBFS的开放式配置对话框[[设备描述符标签] /端点描述符/端点编号-EP1到EP8是EP编号，设置为输入或输出，传输类型为散装，间隔＝0，马克斯包＝64；当添加新的EP时，单击[++Dead Posit]。第二个问题：我正在使用另一个工具，但是我没有Matlab。通常，这种工具具有脚本语言，如VB或Java。如果是这样，控制PSoC USB由那些。呵呵？



     以下为原文
          OK, Piece of cake. As you know, Open Configure dialog of USBFS, [Device Descriptor TAB] / Endpoint Descriptor / Endpoint Number - EP1 to EP8 is EP number, Set IN or OUT, Transfer type is BULK, Interval=0, Max Packet=64; When add new EP, Click [+Add Endpoint]. Second question: I'm using another tool, I haven't have MATLAB however. Usually, This kind of tool has Script Language, like VB or Java. If so, Control PSoC USB by those. huh?   

你好。
谢谢你的回答。我试着用它们来解决我的问题。以下是结果：
1。我已经做过了，但仍然很慢。我需要以40千赫的速率传输16位值。这意味着我需要每秒至少640比特…
2。当我按下传输文件按钮时，我可以像你所说的那样把数据存储到.txt文件中。但是在.txt中，总是只有一个值。我需要的是源源不断的河流。我试图改变“长度”和“十六进制字节”，但它不会改变任何东西。
我还用VisualStudio改变了“控制中心”，所以当我现在按下“数据传输”按钮时，我从端点得到100个值。但是这些值通常是错误的，有时软件完全停止了通信。（错误代码997）你知道如何解决这些问题吗？
谢谢您。

  Hi.
    thanks for the answers. i tried to use them to solve my problems. Here are the results:
    1. I`ve already done that, but its still to slow. I need to transfer 16 bit values with a rate of 40 kHz . This means that i need at least 640.000 Bits per second...
    2. When I press the Transfer File Button I´m able store data to a .txt-file like you said. But in the .txt there´s always only one value. What i need is a continous stream.  I tried to change "length" and "hex bytes" but it doesn´t change anything.
    I also changed "Control Center" with Visual studio, so when i now press the "data transfer" button I get  100 values from the endpoint. but the values are often in a wrong order and sometimes the software stops the communication completely.(Error code 997)  Do you have an idea how to solve these problems ?
    Thank you.
