Ask questions and find answers on ST MEMS sensors, such as the LSM6DSV and the LSM6DSL. Learn how to use the SensorTile.Box, and STEVAL kits.
I'm currently facing a big problem. I've an MCU (STM32L4) connected to an SD card (SDIO) which stores tons of data (5Gb) from a microphone (ST MEMS). I need to send this data as fast as possible from SD card to my PC. With a serial port this is to sl...
Hi,I am using the LSM6DS3 with I2C at 400 kHZ. I would like to know the pin capacitance value so as to calculate the value of the required pull up resistors. I was unable to find this in the data sheet.Thanks
Hi,I would just like to know the date code on the LSM303AGR on our PCB Board. So far I have not found any document to interpret the date code. The markings are 636 AGR.Regards,Markel
Hi,I have been using the LIS3DH successfully but I want to go to the LIS2DE12 because it is smaller and only does what I need. I have wired up a STEVAL-MKI175V1 board to a 3.3 v Arduino close to do some initial evaluation. I can't get it to respond a...
Hello,I connected the nucleo F401RE to max30100 using i2c level shifter tca 9406 https://www.ti.com/lit/ds/symlink/tca9406.pdf?ts=1596413075744, and I am only getting the adderss of the sensor but no data.I also tried to add 10k resistors and got t...
Hello?I have a question.I am developing using MCU.I am using VL53LDK to measure distance.I want to know the I2C Index address.Index address:?How many byte?How can i calculation?Thank you.
Hello everyoneWe are designing a wearable device. It's worn on the waist. We want it can generate an interrupt when a man sit down or stand up, so that we can know a man is sitting or standing. It's a low-power device, wake up every 3 seconds.Now, we...
Hello everyoneOur device use lis2dh12 to measure the acceleration. We tested 10 boards. But we find 3 board work abnormal. These three board are all facing up, the reading of x axis and y axis should be 0, and z axis should be 1g. But the readings o...
I am exploring iis3dwb sensor with stm32f401 nucleo board.i go through the data sheet but not find any information which mode this sensor supported?so i tried with these 2 setting , hspi3.Init.CLKPolarity = SPI_POLARITY_LOW; hspi3.Init.CLKPhase = SPI...
I'm currently using the LPS22HB pressure sensor in order to make a CO2 sensor more accurate. We need to calibrate the pressure sensor so it doesn't incorrectly modify the CO2 reading. We are having difficulty understanding wether the one point calibr...
