LIS2DE12 pull up resistor values
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...
Dont getting data from max30100 connected to NUCLEO F401RE
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...

Use LIS2DH12 detect sit or stand
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...
LIS2DH12 fault
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...
Resolved! which spi mode is supported in iis3dwb sensor and why it fail to read who am i register at first attempt after reset?
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...
LPS22HB non-volatile calibration ?
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...
How to collect sensor fusion and IMU sensor data csv data concurrently on the ST BLE Sensor App with the Steval-STLKT01V1?
On the ST BLE Sensor App, I can only able to either export Accelerometer, Gyroscope, and Magnetometer csv files OR Sensor Fusion csv file. I was wondering if there is a way to export both of these files? Another question, I was wondering if there is ...
Resolved! steval-mki181v1 - i2c connected problem...
Hi, im have:https://www.st.com/en/evaluation-tools/steval-mki181v1.htmlI have connected after i2c in esp32. It works and sometimes disconnects it. Do you need to use any resistors?
