您好,我在CH559HID复合设备例程Compound_Dev_1.4中看到了hid_recv.exe,可以读取HID复合设备的数据,能发上位机的源码参考下吗?谢谢。我试过使用hidapi只能读取单个hid设备,不能读取复合设备的。

hi 各位 我们有个产品用了dlpc2607和pad10000,dlpc2607 i2c通信正常,我想得到pad1000 采样到的温度值,请问下要怎么实现呢? 我对那个compound i2c command不理解,能具体解释下吗?

2607的 Compound I2C Command 命令给光机写数据.一般光机已经是固化了预设了一组值,我只需要把值通过2607写给pad1000就行? 是不是写pad1000 的 SW4/SW5

当为PIC24FJ256GB206做一些Bang-I2C代码时,我意外地将一个错误从我自己(通过计时器工作)改为内置的编译器时引入了一个bug。这是我在复制粘贴过程中最后得到的结果:我没有注意到错误,同时我做了很多其他的改变。然后,当我测试了一个更大的函数,它使用了I2C功能几个级别时,代码就不再工作了。我的问题是:1)为什么C30编译器不把这个标记为一个错误?2)如果这不是一个错误,那么有人能告诉我它会写什么吗?正确的线是这个(并且当改变到这个我的代码开始正常工作): 以上来自于百度翻译 以下为原文 When working on some bit-bang i2c code for a PIC24FJ256GB206 I accidentally introduced a bug when changing a delay call from my own (working via timers) to the compiler built in. This is what I ended up with during the copy-paste:__delay_us(1)(100);I did not notice the error and I was doing a lot of other changes at the same time. Then when I tested a larger function that used the i2c functionality a few levels away the code no longer worked.My questions here are:1) Why did not the C30 compiler flag this as an error?2) If it is not an error, then could someone please tell me what it will do as written?The correct line is this (and when changed to this my code started working properly again):__delay_us(100);

您好,我有一些LabVIEW代码,我试图将其集成到VEE中,并且在大多数情况下,我在模仿相关示例中的过程后已经成功了。但是,当我尝试将值传递给LabVIEW集群时,我遇到了重大问题。有问题的集群包含一个字符串和一个数字,因此我尝试传递具有相同结构的记录。但是,当我这样做时,我得到一个通用错误弹出窗口“Agilent VEE遇到了问题。”当我将此集群作为输出而不是输入传递时,我发现VEE正确处理它并创建一个与我之前构建的记录具有相同结构的记录。是否有任何人可以了解我为什么能够'将记录传递到LabVIEW集群输入中?感谢您提供的所有帮助! 以上来自于谷歌翻译 以下为原文Hello,I have some LabVIEW code that I am trying to integrate into VEE, and for the most part, I've been succesful after mimicing the procedure in the relevant example. However, I am running into major problems when I try to pass a value into a LabVIEW cluster. The cluster in question contains a string and a number, and so I tried to pass a record with the same structure. However, when I do so, I get a generic error pop up window "Agilent VEE has encountered a problem." When I pass this cluster in as an output instead of an input, I've found that VEE handles it properly and creates a record that has the same structure as the one I built earlier.Does anybody have any insight as to why I can't pass a record into a LabVIEW cluster input?Thanks for any and all help!

毫米波长范围(30-300GHz)内除了其较低端外,还没有很好地被利用。而在成像,安全,医疗,和短距离无线传输以及数据速率不断提高的光纤传输中的新应用可能会迅速地改变这种状态[1],[2]。在过去的三十年里,III-V 技术(GaAs 和InP)已经逐渐扩大到这个毫米波范围中。新近以来,由于工艺尺寸持续不断地减小,硅技术已经加入了这个“游戏”。在本文中,按照半导体特性和器件要求,对可用于100-GHz 和100-Gb/s 应用的半导体有源器件进行了综述,介绍了什么是用于甚高频率的半导体技术?接着是两个不同方面具有竞争性的技术现状:分频器,来说明该技术适宜用在高速数字电路中,以及振荡器,用来说明其在模拟电路应用中的性能。
