我們想使用BF707-BLIP2進行開發,因我們規劃的專案規格有250MB DDR2,這是放版子核心core與CCES Debugger使用,所以像 OpenCV wrapper APIs也是放在這嗎?

可以看到一些短暂的“BLIP”。因为我使用MCP16301作为我的功率调节器,我想知道这是否可能是由于调节器的瞬态响应或某事。我试着去耦存储器,增加一些体积电容,这很有帮助,但是问题仍然存在。当我在过

你好,我们是电子工程系的4名学生,我们有一个项目与一个PSoC组件保持距离。我们希望产生一个40 kHz频率的方波,并测量时间响应。我们只有PSoC创建者1软件。我们刚刚开始使用这个软件。为了产生信号,我们使用具有6 MHz时钟和150周期的PWM。但是如何提取反射信号呢?我们已经看到了一些具有计数器的PSoC 3的例子,但是我们的例子是不同的。谢谢你的帮助,最好的问候,阿德里安。JPG40.3 K 以上来自于百度翻译 以下为原文Hi, We are 4 students in electronics engineering and we have the project to mesure a distance with a PSoC component. We want to generate a square waveform with a 40 kHz frequency and to measure the time response. We only have the PSoC Creator 1.0 software. We're just beginning with this software. To generate the signal, we use a pwm with a 6 MHz clock and a period of 150. But how to retrieve the reflective signal ? We have seen some examples for the PSoC 3 with a counter but ours is different. Thanks in advance for your help, Best regards, Adrien. start.JPG 40.3 K

我试图直接指派设备的MAC地址,我不知道它的位置在哪里,我肯定它在某个地方。我将尝试引用它在HEX文件中所说的位置,但是那个位置是0xFF90000,它不是这个芯片上的有效内存位置,或者至少当我试图访问它时,它看起来是硬错误。我在补丁SysSDFS文件中找到了配置的定义地址列表,所有这些地址都在0x02的范围内。我假设0xFFFUNM00转换到那个范围的某个地方。 以上来自于百度翻译 以下为原文I'm trying to reference directly to the assigned mac address of the device, and I couldn't figure out where a defined constant of its location is at, i'm sure it is somewhere. I was going to try and reference to where it says it is at in the hex file, but that location was 0xFF000015, which isn't a valid memory location on this chip, or at least it appears to hard fault when I try to access it. I did find a list of defined address locations for configurations in the patch sysmdefs file, and all of those addresses are more in the range of 0x20000. I'm assuming that 0xFF000000 translates to somewhere in that range.

我是PSooCluetooth的初学者,请原谅我的问题。我在BLE车间工作,我成功运行了LAB1-2-3。但是没有任何关于认证的实例。我已经将我的Loap组件设置为Gap外围设备,并将安全级别更改为“通过加密进行身份验证配对”,但我不知道如何配置密钥?有没有与PASKEY配对的简单例子?我只想和我的主机(GAP中央设备)配对,然后让它从外围设备读取一个字节的设备ID。

我目前在我们实验室中的12端口扩展设置中出现了一些不稳定的行为。这是N5230C与FW 09.46.xx上的U3042A E12装置配合使用。我在~1GHz以下的所有单端对上得到的数据相对较差。有趣的是,此行为仅在启用12端口扩展并跨所有端口时显示。到目前为止,我已经尝试过:恢复旧固件尝试不同的电子校准单元交换跳线(当然这不会有帮助,因为它困扰所有测量)仔细检查我们的错误条款似乎是合理的(他们这样做)贯穿整个没有电源孔的12端口扩展的故障排除指南。这是我的第一次猜测,因为过去我们因为这个原因而遇到了问题。我附上了两张图片:一张带有校准功能,一张带有校准功能,比较分析仪的性能,无论是否启用了跳线/多端口。我使用S21来表明这不仅仅是扩展端口上的问题,只有当跳线通过多端口时。正如我所说,这是困扰所有端口的任何东西。在这种情况下,DUT是我们其中一个校准板上的小直通迹线。还有什么我可以调查以隔离问题,或者是否有任何关于发生了什么的想法?我还提供了我拍的.s2p文件,虽然我可以提供一个.s16p文件,我也抓住了这个行为。任何帮助将不胜感激S21WithoutCal.png24.8 KBNoMultiPortCalOn.s2p42.4 KBNoMultiPortCalOff.s2p46.4 KBMultiportWithCalOff.s2p46.4 KBMultiportWithCalOn.s2p42.2 KB 以上来自于谷歌翻译 以下为原文I'm currently having some erratic behavior occurring with one of our 12-port extension setups we have in our lab.This is an N5230C mated to a U3042A E12 unit on the FW 09.46.xx. I'm getting some relatively poor data on all single-ended pairs under ~1GHz. Interestingly, this behavior only shows up when the 12-port extension is enabled and across all ports.So far I have tried: Reverting to old firmware Trying different electronic calibration units Swapping jumpers around (of course this wouldn't help, since its plaguing all measurements) Double-checking that our error terms seemed reasonable (and they do) Running through the troubleshooting guide for the 12-port extension with no power holes to be found. This would've been my first guess, as we've had problems with it for this very reason in the past. I've attached two images: one with calibration on, one with calibration off comparing the Analyzer's performance with and without the jumpers/multi-port enabled. I used S21 to show that this isn't an issue just with ports on the extension, only when the jumpers are run through the multi-port. As I've said, this is plaguing any thru on ALL ports. The DUT in this case is a small thru trace on one of our calibration boards. Is there anything else I can investigate in order to isolate the problem, or is there any idea as to what is going on? I've also supplied the .s2p files I took, though I can supply an .s16p file where I caught this behavior as well. Any help would be appreciated附件S21WithCal.png24.5 KBS21WithoutCal.png24.8 KBNoMultiPortCalOn.s2p42.4 KBNoMultiPortCalOff.s2p46.4 KBMultiportWithCalOff.s2p46.4 KBMultiportWithCalOn.s2p42.2 KB
