FX2丢弃数据包

你好，Chris Hawthorne，
-请让我知道，如果数据从FPGA或外部设备转移到FX2，然后到主机PC。如果是这种情况，亲切地，探测IFCK，SLWR和数据线。
另外，如果您使用的是CyPress提供的主机应用程序，或者是您自己的自定义应用程序，请告诉我。
-好心地，使用像LeCryy这样的硬件分析器或者像USBLyzer这样的软件分析器捕获USB跟踪。
最好的问候，
斯里纳斯

Hello Chris Hawthorne,

- Please let me know if the data is transferred from an FPGA or external device to the FX2 and then to the host PC. If this is the case, kindly, probe the IFCLK, SLWR and the data lines.
- Also, let me know if you are using a host application provided by Cypress or is it your own custom application.
- Kindly, capture the USB traces using either a hardware analyzer like LeCroy or software analyzer like USBLyzer.

Best regards,

该装置产生的16字节的数据在11khz大量使用USB传输。每16个字节或数据线我们从应用来看，有意义。两个16位字节连接我们的ADC则连接到包括RTC和线计数器各数据点。这是我们如何知道我们正在下降的数据。我们有我们自己的软件生成。有时取决于计算机使用它将运行小时没有一滴。有时它会运球一点数据。数据的准确性是99%以上，但客户想看看我们是否能得到它更好因为我们通常下降512个字节的时间是在屏幕上32行数据。有一个安全的方式，我可以在柏树审查固件代码有一个支持工程师和软件电话，看看有什么可以优化得更好一点？我们有问题在过去的数据下降，Vikas能够帮助。如果需要我能发送一个链接的情况下。



以下为原文
The device generates 16 bytes of data at 11Khz using a Bulk USB transfer. Each of the 16 Bytes or a line of data as we see it from the application, has significance. Two 16 bit bytes connect to our ADC while the others connect to various data points including a RTC and a line counter. This is how we know we are dropping data. We have generated our own software. Sometimes depending on the computer used it will run hours without a drop. Other times it will dribble a bit of data. The data accuracy is above 99% but the client would like to see if we can get it better since we typically drop 512 bytes at a time which is 32 lines of data on the screen.. Is there a secure way I can have one of the support engineers at Cypress review the firmware code and the software calls to see if there is something that can be optimized to get a little better yield? We have had issues in the past with data drop and Vikas was able to help. I can send a link to the case if needed.
