从物联网从业者的角度来看,经常看到对计算更加可用和分布式的需求。当开始将物联网与OT和IT系统整合时,面临的第一个问题是设备发送到服务器的庞大数据量。 在一个工厂自动化的场景中,可能有数百个集成的传感器,这些传感器每1秒发送3个数据点。大部分的传感器数据在5秒钟之后就完全没用了。 数百个传感器,多个网关,多个进程,和多个系统,需要几乎在瞬间处理这些数据。大多数数据处理的支持者都支持云模型,即总是应该向云发送一些东西。 这也是第一种物联网计算基础。

你好,我用I2C块读取一个字节在一个无限循环中的从属设备寄存器值。我使用的逻辑是:I2C*START();I2C.MistCurrStaseSube();I2CyMasksEngStEnter(设备地址,0x00);I2C.MigWrimeWrimeEnter(地址);I2C.MaskestEntRead(设备地址,0xFF);RDYBuff==I2C*MaultRead字节(0);I2CyMasksEdStestStor();I2C~();我在RDI Buffi中获得了注册值。这工作时间很长,但逻辑在某个地方挂起,而我的代码没有进一步运行。原因何在?我使用调试器检查代码停止的位置。我发现,当师父正在产生重启时,我会因为等待而陷入困境。请建议。

嗨,我正在以一个频率连续地以随机顺序接收数据包,并且我想要以相同/不同的频率按顺序缓冲和输出它们。正常的FIFO不起作用,因为数据包不会是“先进先出”,缓冲区大小应该是多少?有什么线索吗?提前致谢桑杰以上来自于谷歌翻译以下为原文Hi, I'm are receiving packets of random length and in random ordercontinueously at one frequency and I want to buffer and output them in sequence at same/difference frequency. Normal FIFO will not work, as packet is not going to be "first in first out" and what should be the buffer size? Any clues? Thanks in advanceSanjay

MCU/TOOLSPIC32MX795F512L、MPLAB X、XC32 1.34I正在与一个客户机合作,该客户机希望将数据文件作为PDF记录并存储到SD卡中。我熟悉TXT、CSV格式的数据存储,但是,对于创建PDF我一无所知。在测试了这个主题之后。因此,在仪器从现场返回之前,不涉及任何计算机。我已经完成CSV了。有人知道如何把数据作为PDF保存到SD卡吗?我已经找到了一些信息,但是,我还没有研究。谢谢。

你好,我在CY8CKIT-042-BLE先锋套件上进行了电流消耗测量。测量主要集中在广告的BLE,广告在所有三个可能的渠道。在执行电流测量时,我做了一个奇怪的观察,我对此没有任何解释。也许这里有人可以帮助我:在“广告包”不变的情况下留下数据字节,改变“扫描响应包”数据(因此不同的字节数)在电流和功耗方面表现出巨大的差异。首先,我认为这是因为另一个BLE设备正在扫描。但事实并非如此。没有观察到的扫描响应。仔细观察广告事件表明,频道间延迟的持续时间存在差异。因此,例如,当选择31字节的扫描响应包时,信道间延迟需要更长时间,如选择3字节的扫描响应包。然而,从来没有发送扫描响应。根据AN92584[ 1 ],第37页,信道间延迟应该固定在1.25MS,这在我的情况下绝对不是真的。然而,根据蓝牙标准4.2,这种信道间延迟必须小于10ms,因此当然,功能不受限制。有人能告诉我为什么频道间的延迟是可变的吗?它背后的原因是什么?托拜厄斯,最好的问候和感谢[1 ] HTTP://wwwyCysP.COM/FIL/14091/1下载 以上来自于百度翻译 以下为原文Hello, I performed current consumption measurements on the CY8CKIT-042-BLE Pioneer Kit. The measurements were mostly focused on the advertising of BLE, advertising on all three possible channels. While performing the current measurements I made a strange observation where I have no explanation for. Maybe someone here can help me: Leaving the bytes of data under "Advertisement packet" constant and changing the "Scan response packet" data (so different number of bytes) showed a huge difference in current and therefore in power consumption. First I thought this would be because of another BLE device which is scanning. But this was not the case. There were no scan responses observable. Taking a closer look to the advertising event showed that there was a difference in the duration of the Inter-Channel-Delay. So, e.g., when choosing a scan response packet of 31 Bytes, the Inter-Channel-Delay took longer as when choosing a scan response packet of 3 Bytes. Nevertheless, the scan response was NEVER sent. According to AN92584 [1], page 37 the Inter-Channel-Delay should be fixed at 1.25ms, which is in my case definitely not true. Nevertheless, according to the Bluetooth Standard 4.2 this Inter-Channel-Delay has to be shorter than 10ms, therefore of course the functionality is not restricted. Could someone explain to me why the Inter-Channel-Delay is variable? What is the reason behind it? Best regards and many thanks in advance,Tobias [1] http://www.cypress.com/file/140991/download

嗨,大家好,我正在使用CYBLE 01200 11-00 BLE模块。我有3个从设备,每个都有基于I2C的传感器和RTC模块。并具有基于I2C的传感器和RTC模块。项目需求是周期性的,应从3个奴隶接收数据,过程应该继续进行。为了实现与奴隶和主人的有效沟通,我应该执行哪些配置文件。我应该怎样去寻求安全和期望的联系?谢谢,萨加尔 以上来自于百度翻译 以下为原文Hi all, I am using CYBLE 0120011-00 BLE module. I have a 3 slave devices each has I2C based sensor and RTC module. and also Have master with a I2C based Sensor and RTC module. project requirement is periodically mater should receive data from 3 slaves and process should go on. which BLE profile should i implement for effective communication with slave and master. how i should go for security and desired connection? Thanks,sagar.

你好,我和PSoC Creator有一个大问题。我想把我的CY8CKIT-042编程成一个字母数字LCD、LED和开关,但我对项目的创建一无所知。我只想编写一个代码并在卡中构建它,但我不能。有没有办法在不创建一些项目的情况下编写代码?另外,当我想集成一个头文件时,它说文件是不可追踪的,这是安装过程中的问题吗?我希望你能帮助我,因为我必须在1月15日之前完成。谢谢你的阅读。
