嗨，我的STEVAL-MKI109V2主板带有LSM9DS1惯性测量单元和STEVAL-MKI159V1适配器。 ST Microelectronics已经在提供该软件。但我想通过LabView整合主板的输出。有人可以告诉我是否可以使用LabView作为此主板的采集软件而不是ST Microelectronics默认软件？ ＃inemo-M1以上来自于谷歌翻译以下为原文 Hi,I have STEVAL-MKI109V2 motherboard with LSM9DS1 Inertial Measurement unit and STEVAL-MKI159V1 adaptor. ST Microelectronics is already giving the software. But I would like to integrate the output from the motherboard through LabView. Can someone please tell me whether it is possible to use LabView as acquisition software for this motherboard instead of ST Microelectronics default software? #inemo-m1

嗨， 我尝试在低功耗模式（电源电压3V）下使用LIS331HH获得大约10 uA的功耗。但是我在低功耗模式下的平均功耗为23 uA（0.5 Hz数据速率）。工作周期：睡眠（功耗约5 uA）2秒 - “唤醒”（290 uA）小于0.1秒 - 睡眠（5 uA）2秒-...等等因此，结果约为23 uA，但目标功耗为10 uA（数据表）。我应该改变什么？掉电模式下的功耗小于1 uA（已测试）。以上来自于谷歌翻译以下为原文 Hi, I try to get power consumption about 10 uA using LIS331HH in low-power mode (power supply voltage 3V).But I've got 23 uA average power consumption in low-power mode (0.5 Hz data rate). Working cycle: sleep (power consumption about 5 uA) 2 sec - ''wake-up'' (290 uA) less than 0.1 sec - sleep (5 uA) 2 sec -...and so on So, result is about 23 uA, but target power consumption is 10 uA (datasheet). What should I change? Power consumption in power-down mode is less than 1 uA (tested).

嗨， 我刚买了新的MKI109V2主板，并为DFU和VCP安装了驱动程序。开始时，我可以在PC上检测VCP并使用DFU DEMO升级固件。升级固件DFU_Patcher_V1.0.2.dfu后，我无法再检测到VCP，但仍能通过DFU DEMO升级FW，然后在PC上无法检测到VCP和DFU。现在我的主板D5 LED始终亮着。 我的问题是如何用固件应该重新编程它。我从stsw-mki109w的软件包中获得了eMotionV2_REL_4_2.dfu。 谢谢！＃STEVAL-mki109v2以上来自于谷歌翻译以下为原文 Hi, I just got new MKI109V2 motherboard, and installed the driver for DFU and VCP. At the beginning, I can detect VCP on my PC and use DFU DEMO to upgrade firmware. After upgrading firmware DFU_Patcher_V1.0.2.dfu, I cannot detect VCP anymore but still be able to upgrade FW via DFU DEMO and then none of VCP and DFU was able to detected on PC. Now my motherboard D5 LED is always ON. My question is how I can reprogram it with what firmware is supposed to be. I got eMotionV2_REL_4_2.dfu from the package of stsw-mki109w. Thx!#steval-mki109v2

嗨，大家好 我正在使用STMEVAL-MKI109V2进行LSM9DS0，使用4线SPI通信？如果在EVAL板上电后保持CS_G = 0且CS_XM = 1，但在CS_G = 1和CS_XM后CS_G = 0，则读取陀螺仪的WAI reg是正常的= 1，读取WAI reg，MCU无法得到任何响应（SDO = 0xFF总是），有人可以解释一下为什么？如果有人能发布LSM9DS0 SPI通信代码，我将不胜感激。谢谢。 ＃lsm9ds0-4-wire-spi＃psm9ds0-purchase以上来自于谷歌翻译以下为原文 hi,guys I'm working on LSM9DS0 with STMEVAL-MKI109V2,using 4-wire SPI communication?read gyro's WAI reg is ok if keep CS_G=0 and CS_XM = 1 after EVAL board power on, but if CS_G=0 after CS_G=1 and CS_XM = 1,read WAI reg, MCU can't get any response(SDO=0xFF always),can anyone explain me why? I would be grateful if anyone could post LSM9DS0 SPI communication code. thanks. #lsm9ds0-4-wire-spi #psm9ds0-purchase

你好社区，因为几个月后我在我以前使用K1的VDI农场安装了一些P40。从那时起我就产生了一个奇怪的效果：当我打开一个新窗口时，例如当我开始一个新程序时，我会看到半秒钟的背面和白色方格窗口，而不是程序窗口。在这个短暂的闪光后，该应用程序正常工作。这是一个已知的错误？亲切的问候克里斯蒂亚诺以上来自于谷歌翻译以下为原文Hello community,since a couple of months I have installed some P40 in my VDI farm where I previously was using K1.Since then I have a strange effect: when I open a new window, for example when I start a new program, I see for half a second a back and white checkered window instead of the program window. After this brief flash, the app works normally. Is this a known bug?Kind regardsCristiano

我正在尝试将UNICO与包含LPS22HB传感器的评估板一起使用。我在他们的环境传感器设备列表下找不到此设备。有没有办法将其添加到列表中，或更新UNICO？我使用的是4.2.0.0版。是否有更新版本的LPS22HB压力传感器？ ＃lps22hb-sensor-non-recognition＃lps22hb-unico以上来自于谷歌翻译以下为原文 I'm trying to use UNICO with an eval board that contains the LPS22HB sensor.I cannot find this device under their Environmental sensors device list.Is there a way to add it to the list, or to update UNICO?I'm using version 4.2.0.0.Is there an updated version that has the LPS22HB pressure sensor in it?#lps22hb-sensor-non-recognition #lps22hb-unico
