not recieve any impulses. I cheched it with oscilloscope and it also showed that there are no voltage impulses.

impulses on the SCK1 pin and nothing happens on the SDO1. Can't understand what is the problem. Any help would be very appreciated.

大家好：以CY8C4146AZI S433为代表的BLDC系列产品，用于生产和销售。1：IVION CYFLASH.UCIT32 32 CysSyFlash书写器（UTI32 RunnUM，const UITN8 ROWDATABOR[O]）你的尺寸是多少？2：闪存？ 以上来自于百度翻译 以下为原文Hi All： 客户使用CY8C4146AZI-S433来开发一款BLDC电机的产品，需要对芯片的flash进行操作，关于Psoc4的flash的操作有几个问题需要请教一下： 1：我发现CyFlash.c里面的函数uint32 CySysFlashWriteRow(uint32 rowNum, const uint8 rowData[])是一个先进性擦除后写的动作，没有擦除和写分开的函数，这样的操作是否可行？可行的话，可否帮写一个单独写一个flash row size和单独擦除一个flash row size的函数？客户需要用到这样的操作？2：flash操作有没有整个芯片擦除的操作？

嗨！更详细的情况：33500产生1000Hz的窦。我想开始扫描（2秒内1000-> 2000Hz），但我希望它与当前波形“同步”开始。当我发送SCPI命令时，我不希望它立即切换到扫描。相反，扫描应在当前正弦周期结束时开始（无缝转移）。可能吗？怎么样？注意：任意不是一个选项，因为我不知道提前扫描的需要...非常感谢！ 以上来自于谷歌翻译 以下为原文Hi! The situation in more detail: The 33500 generates a sinus with 1000Hz. I want to start a sweep (1000->2000Hz in 2s), but I want it to start "in phase" with the current waveform. I don't want it to immediately switch to sweep when I send the SCPI-command. Instead the sweep shall start when the current sinus period is finished (seamless transfer). Is it possible? How?Note: arbitrary is not an option since I don't know in advance when the need for the sweep appears... Many thanks!

标题真的说明了一切。 LSM9DS1的引脚说明表明DEN_A / G引脚是加速度计/陀螺仪数据使能。这听起来很重要，但我无法在数据表中的任何地方看到它解释了您的意图。我可以将其绑定到3.3V，因为我希望始终启用数据吗？还是把它绑在地上？或者也许是CS_A / G引脚，这样只有当我没有与它进行通信时它才会读取数据？ 我唯一不能做的就是将它连接到微控制器引脚，因为我已经用完了。 谢谢你的帮助 #data-enable＃lsm9ds1＃den_a / g以上来自于谷歌翻译以下为原文 The title really says it all. The pin description for the LSM9DS1 says that the DEN_A/G pin is the Accelerometer/Gyroscope Data Enable. This sounds important, but I can't see anywhere in the datasheet that explains what you're meant to do with it. Can I just tie it to 3.3V, since I want data to always be enabled? Or tie it to ground? Or maybe to the CS_A/G pin, so that it only takes readings when I'm not actually communicating with it? The only thing I can't do is connect it to a microcontroller pin, because I've run out of those. Thanks for any help #data-enable #lsm9ds1 #den_a/g

怎样使用Simple FOC库运行编码器呢？编码器中断设置该怎样去实现呢？

亲爱的大家， 我想使用在spartan-6 FPGA微板中实现的VHDL编码来实现最低分辨率的TDC（时间到数字转换器）...我已经阅读了一些关于实现的信息，其中一个技术是多个延迟线......但是我仍然对它的编码感到困惑......我是VHDL的famaliar ...我只是想要一些关于如何在这个任务中开始编码的指导....如果有人有一些经验可以分享，对我来说非常有帮助.......问候，MSD以上来自于谷歌翻译以下为原文Dear all,I would like to implement TDC(time to digital converter) of least resolution possible using just VHDL coding implemented in spartan-6 FPGA microboard... I have read some info regarding the implementation, one of the technique multiple delay line...however I am still puzzeled about its coding...I am famaliar with VHDL...and I just want some guidance about how to start coding in this task....if anyone has some experience to share that would be very helpful for me.......

你好。我拥有一台DSO-X 2002A 2通道70MHz 2 GSa / s示波器，我正试图通过发射器/接收器P波换能器在岩石核心内的某些边界的反射上进行双向传播。问题是我只看到示波器显示屏上的脉冲。我检查了电缆是否连接在正确的端口，经过了所有可能的配置（Itried改变波的频率，幅度，增益，阻尼，高通和低通滤波器等等，它仍然没有给我一个值得分析的信号）。我的岩石核心长度为6.5厘米，p波速度略高于4000米/秒，其中第一个也是最重要的边界是在第一个1厘米之后，尽管应该给出最高阻抗的边界是边界它的核心和铝板下面（6.5厘米），我在信号中看不到。 prtscr.jpg是脉冲发生器的规格; sig_inter.png是没有核心连接到传感器的信号; dig_read_inter.png是核心连接到传感器的信号。任何人都可以帮我弄清楚为什么我无法看到边界反射的正确信号？干杯! sig_inter.png22.0 KBprtscr.jpg112.6 KB 以上来自于谷歌翻译 以下为原文Hello. I possess a DSO-X 2002A 2 channel 70MHz 2 GSa/s oscilloscope and I'm trying to two way travel time's on reflections in some boundaries within a core of rock through a transmitter/receiver P-wave transducer. The problem is that I only see the impulse on the oscilloscope's display. I've checked the cables are connected in the right port's, went through all of the configurations possible (Itried to change the wave's frequency, amplitude, gain, damping, high and low pass filters and so on and it still isn't giving me a signal worth analyzing). My core of rock has 6,5cm lenght, p-wave velocity is a tiny bit higher than 4000m/s and the first and most importante boundary within it is just after the first 1cm although the boundary that should give the highest impedance is the boundary of the core and the aluminum plate it has underneath (at 6,5cm) which I don't see either in the signal. prtscr.jpg is the specs for the pulser; sig_inter.png is the signal without the core attached to the transducer; dig_read_inter.png is the signal with the core attachedto the transducer. Can anyone help me figure out why I haven't been able to see a proper signal with the boundaries reflections? Cheers!附件sig_read_inter.png25.3 KBsig_inter.png22.0 KBprtscr.jpg112.6 KB
