我用的脉冲激光测距,峰值功率可以达到70w,脉宽大概100ns左右,测距范围100m以内,请问可以用PIN作为光电探测器接收吗?后面的TIA放大大约10K-20K倍,另外,这个是不是对光学准直和接收系统要求很高,方便起见,单透镜可以准直吗?

,我将非常感激。这将有助于确定这种时髦、功能丰富的MCU是否适合我的低功耗项目(在大约500 kHz下运行大约25%的时间)。非常感谢,卫国明。 以上来自于百度翻译 以下为原文 Hi

我正在使用一种产品(我们称之为键盘),它使用CY8C2664作为它的MCU,并通过RS485与另一主机设备通信。我们在现场与键盘和主机设备之间的通信存在问题,并确定键盘发射机的波特率为3.5%。MCU的主要时钟源是IMO。我检查了UART的时钟分频器设置,发现它们是基于24MHz IMO的期望而正确设置的。然后,用O型范围直接测量时钟速率,并基于我的测量值和我计算的除法器设置。艾德说,IMO实际运行在23.17MHz,误差为3.5%。PSoC技术参考手册在PG109上表示IMO将在2.5%的公差范围内,因此MCU看起来运行不正常。现在看来,唯一的选择是尝试通过IMOOTR来调整IMO修剪。然而,我们早在0543就有了MCU日期代码的字段中的许多键盘。0543部分具有23.75兆赫的IMO FRQ,并且没有波特率问题。我们遇到的设备的日期是1043。这就是我的问题…我们在这个领域有几千个设备,那么我们怎样才能以简单、方便的方式定制每个设备呢?有没有一个程序员POD或软件会自动为我修剪IMO?谢谢。 以上来自于百度翻译 以下为原文I am working with a product (lets call it a keypad) that uses the CY8C27643 as it's MCU and communicates with another host device over RS485.We have had problems in the field with communications between the keypad and the host device and determined that the baud rate of the keypad transmitter was off by ~3.5%.The primary clock source for the MCU is the IMO.I checked the clock divider settings for the UART and found that they were set correctly based on the expectation of a 24MHz IMO.I then measured the clock rate directly with an o-scope and based on my measurements and the divider settings I calculated that the IMO is actually running at 23.17MHz, an error of 3.5%.The PSOC technical ref manual states on pg109 that the IMO will be within 2.5% tolerance, so the MCU appears to be operating out of spec. It looks like the only option right now is to try to adjust the IMO trim via IMO_TR.However we have many keypads in the field that have MCU date codes as early as 0543.The 0543 parts have an IMO freq of 23.75MHz and do not have baud rate problems.The date of the device we are experiencing problems with is 1043.So heres my question..... we have several thousand devices in the field, so how can we custom trim each device in a simple, expedient manner?Is there a programmer pod or software that will auto trim the IMO for me? Thanks.

我们已经注意到在低温下启动FX3的一些问题。我们有一个产品上使用CysB3014-BZXI,它使用了一个从24FC256I/SN正确加载的I2C引导加载程序。注TTAT板上的所有其他部分也额定为全工业温度范围。这个引导装载器查看附加的SPIFFlash(微米N25Q128A11B1240E)以获得更大的启动映像。.在室温下,这个过程运行良好。SPIGION被加载并引导FX3。设备正确枚举。.在低温度(接近0C)时,引导加载程序无法从SPI中检索图像。失败后,它被设计为枚举自己的设备,并且可以接受非常有限的指令。.到目前为止,这些都是现场故障,目前还没有在实验室进行评估。我们没有太多的信息,但想看看是否有人经历过这一点。 以上来自于百度翻译 以下为原文We have noticed some issues with booting the FX3 at low temperatures.We have the CYUSB3014-BZXI on a product which uses an I2C bootloader that is loading correctly from a 24FC256-I/SN.Note thtat all other parts on the board are also rated for the full industrial temperature range.This bootloader looks to the attached SPI Flash (Micron N25Q128A11B1240E) for a larger boot image. . At room temperatures, this process has worked fine.The SPI image is loaded and boots the FX3.The device correctly enumerates. . At low temperatures (approaching 0C), the bootloader fails to retrieve the image from SPI.Upon failure, it is designed to enumerate as its own device and can accept very limited instructions. . These have been field failures so far and not evaluated in the lab just yet.We don't have too much information yet but wanted to see if anyone else had experienced this.

一般来说,天线口径越大,节目的信号越强,接收质量越高。但考虑到成本、安装等因素,用户要求天线口径越小越好。

嗨,大家好,在一些帖子中,当省略32千赫时钟时,会出现问题。这个问题显然取决于该版本的SDK和FX3。今天你可以推荐安全地省略32 kHz时钟时,无需在待机模式下一个看门狗吗?当做格恩特 以上来自于百度翻译 以下为原文Hi all, in some postings problems are indicated when omitting the 32 KHz clock. The problems obviously depend on SDK and FX3 silcon revisions. Can you today recommend to safely omit the 32 Khz clock when there is no need for a watchdog in standby mode? Regards Günter
