大家好！昨天在淘宝上 看到一个wife移动电源，7800毫安，在充满电情况下，只给其自身的wife模块供电，大约能供多长时间。 谢谢！

手头上有无线wife设备需要实时读取数据。我利用TCP做的 ，但是在实时传输过程中偶尔会有数据读取不全丢数据，而后面在此刷新的时候会多出数据来。听别人建议说最好是实时保存数据同过server来实现。不知道该如何实现?????哪路大神对TCP或者RS232串口做的多能指导一下！感激不尽！！！！

如题，办公室是千兆的光纤，安装有无线路由器我家离办公室大概有3、4百米的距离，中间基本没有阻隔物，如何能够接收到办公室无线路由器的信号，并输出为网线接口，接入家里的无线路由器，供家里的设备上网？

我正在尝试在第二台Linux计算机（LInux Mint）上安装WebPack。内置的许可证管理器在第一台计算机上无法为我工作，但通过访问Xilinx许可站点，我可以通过电子邮件向我发送许可证。这适用于第一台计算机。现在我无法为我的第二台计算机生成WebPack许可证，因为我已经在我的帐户上分配了一个。虽然有人说有些人认为WebPack许可证不是节点锁定的，但由于主机ID不匹配，因此不能简单地复制和使用第二台机器上的第一个许可证。我可以在两台机器上运行WebPack吗？如果是这样，我怎样才能获得许可证，而不是在Xilinx上创建第二个帐户？以上来自于谷歌翻译以下为原文I am trying to install the WebPack on a second Linux computer (LInux Mint).The built-in license manager did not work for me on the first computer, but by going to the Xilinx Licensing Site I was able to get a license emailed to me.This worked fine for the first computer.Now I am unable to generate a WebPack license for my second computer because I already have one assigned on my account.Although is said somewhare that the WebPack license was not node-locked, it does not work to simpy copy and use the first license on the second machine because Host ID does not match. Am I allowed to have the WebPack running on two machines?If so, how can I get a license, shortof creating a second account with Xilinx?

我认识到我必须从MPLAB 8移动到MPLAB X，但是，现在两个都下载了，我非常害怕。至少“8”给了直觉工作的机会——“X”一点都没有，据我说，“折射器”之类的术语让我起鸡皮疙瘩。这里的人能推荐最好的教程吗？E？谢谢 以上来自于百度翻译 以下为原文 I recognize that I must move to MPLAB X from MPLAB 8 but, having both of them now downloaded, I am quite intimidated. At least "8" gives some chance for intuition to work - "X" none at all, according to me - and terms like "refractor" give me goose bumps. Could people here please recommend the best available tutorial for those wanting to make this transition - one that actually talks to human beings in plan language? Thanks

我是Xilinx和FPGA的新手。 我有一个Spartan3A入门套件。我的困惑在于ISE Project Navigator和Xilinx Platform Studio。有什么不同？ 我知道：很多！，但我的意思是他们最终都编程了FPGA吗？平台工作室XPS了解我的入门套件板的所有信息，但ISE并不知道哪个LED连接到我板上的哪个FPGA引脚。 你什么时候使用ISE vs XPS？（我对Microchip PIC和各种IDE有很多经验，但我很无聊，决定看看FPGA的世界是什么。）任何输入的Thanx。以上来自于谷歌翻译以下为原文I'm brand new to Xilinx and FPGAs. I have a Spartan3A Starter kit. My confusion is over ISE Project Navigator and Xilinx Platform Studio. What's the difference? I know: Alot!, but i mean do they both end up programming the FPGA? The Platform Studio, XPS, knows all about my Starter Kit board, but the ISE doesn't know like what LED is connected to what FPGA pin on my board. When do you use ISE vs XPS?(I have lots experience with Microchip PICs and various IDE's, but I was bored and decided to see what the world of FPGAs holds.) Thanx for any input.

嗯，我从来没有这么沮丧过。我的计划失败了。我准备放弃使用MCC，在一年左右再试一次。使用16F1827与MPLAB C IDE v3.35我用MCC 3.15Mtouch对四个按钮进行mtouch操作，在8mHz以上与INTOSC不工作。使用PWM3和PWM4但不使用mTouch按钮，不能使用EPWM1和EPWM2与si一起工作。MPLESMCC。代码编译和加载。什么也没有发生。没有定时器的组合。当输出被配置为GPIO，但不使用EPWM时，我可以设置位。如果我使用定时器，然后决定从项目资源中删除它，那么在我尝试构建时，代码仍然会抛出错误。计时器出现在设备资源中。如果我把定时器放回Project资源中而不使用它，代码就会再次编译。当我不那么沮丧时，我会整理一篇完整的帖子。我可能不得不手动重新做这件事，它花费的时间更少，而且工作起来了，并且我理解它是如何工作的。对于MCC，如果代码不工作，我会不知所措。克雷格的作品 以上来自于百度翻译 以下为原文 Well,I've never been so frustrated.My project is stalled. I'm ready to give up on MCC and try it again in a year or so. Using 16F1827 with MPLAB C IDE v3.35I got mtouch working on four buttons with MCC 3.15Mtouch did not work with INTOSC over 8mHz. Got PWM3 and PWM4 working but not with the mTouch buttonsCANNOT get EPWM1 and EPWM2 to work at all with the simplest mcc set up.Code compiles and loads. Nothing happens. No combination of timers works.I can set the bits when the outputs are configured as GPIO but not with EPWM. If i use a timer then decide to delete it from the project resources, code remains that throws an error when I try to build. Timer appears in the Device Resources.If i put the timer back into Project resources and NOT use it, code compiles again. I will put together a complete post when I'm not so frustrated.I may have to go back to doing this manually, It took less time and it worked, and I understood how it worked.With MCC I am at a loss if the code does not work.

我有一台HP 8720D VNA和Agilent 85033E校准套件，想测量一台SMA母设备。该设备实际上是SMA短路，我想找到参考平面和短路之间的距离。但我得到的结果看起来并不太好，我怀疑它是由于SMA与3.5毫米之间的不匹配，但我可能错了。但我不知道如何最好地纠正这个问题，或者至少减少它的影响。如果我从85033E校准套件中取出* 3.5 mm母短标准*，并应用等于短路偏移延迟的端口扩展，则在史密斯圆图上，设备看起来像左边的点。毫不奇怪，如果我现在用* SMA母短*替换3.5毫米短片，我无法找到任何端口延伸，史密斯圆图在左边显示一个点。史密斯圆图视图（手工编辑，因为我的软件没有非常清楚地显示它），显示端口扩展为25.854 ps的视图。注意，相位首先在一个方向上，然后在3.5 GHz左右改变方向。在用Excel绘制的图表上应该更容易看到。我有什么想法可以找到这个SMA女性短片的偏移延迟？我附上了两个Touchstone文件。 * sma-short-0ps.s2p是用*无端口扩展*测量的SMA短路。 * sma-short-25.854ps是用* 25.854 ps端口扩展测量的SMA短路*有没有人评论我的结果是否令人惊讶，或者可以做些什么（如果有的话）来改善问题。也许我只是要求太多的非精密连接器。 DaveEdited：drkirkby于2013年4月3日8:12 PM SMith-Chart-SMA-short-25.854ps-port-extension.PNG26.8 KBPhase-SMA-short.PNG43.1 KBsma-short-25.854ps.s2p59。 6 KB 以上来自于谷歌翻译 以下为原文I've got an HP 8720D VNA and Agilent 85033E calibration kit, and want to measure an SMA female device. That device is actually an SMA short and I want to find the distance between the reference plane and the short. But the results I'm getting don't look too good, and I suspect its due to the mis-match between SMA and 3.5 mm, but I may be wrong. But I don't know how best to correct this, or at least reduce its effects. If I take the *3.5 mm female short standard* from the 85033E calibration kit, and apply a port extension equal to the offset delay of the short, then on the Smith Chart the device looks like a dot on the left. No great surprise that If I now replace the 3.5 mm short with an *SMA female short*, I am unable to find any port extension at which the Smith Chart shows a dot on the left. The Smith Chart view (hand edited as my software was not displaying it very clearly), shows the view with a port extension of 25.854 ps. Note the phase first goes in one direction then changes direction around 3.5 GHz. It should be easier to see on the graphs plotted with Excel. Any thoughts on what I can do to find the offset delay of this SMA female short? I've attached two Touchstone files. * sma-short-0ps.s2p is the SMA short measured with *no port extensions*.* sma-short-25.854ps is the SMA short measured with *25.854 ps port extensions* Has anyone any comments as to whether my results are surprising, or what (if anything) can be done to improve matters. Perhaps I am just asking too much of a non-precision connector.
