How to read multiple IKS01A03 memory register with DMA over i2c?
Hi,I am currently working on DMA combined with I2C bus. I want to read acceleration data from IKS01A3 with HAL function HAL_I2C_Mem_Read_DMA(). I want to read at 6 different memory registers. How can I use that function to get it work properly? Can I...
Why acceleration data of LSM303D on the Z-axis doesn't work?
Hi,I have a LSM303D, compass, and acceleration sensor. I can communicate with the sensor, and I get the magnetometer data on all of the axes, unlike the accelerometer. Accelerometer Z-axis data comes "-32760" all the time. I work on stm32f103c8t6Here...
WHO_AM_I register value read as 0xFF
Hello ST Community,I have some hardware samples with LIS2DH12 accelerometer. For all the samples except one, the value of WHO_AM_I register is read as 0x33 (which is expected). However, for one of the samples, it is read as 0xFF. What could be the po...
Resolved! LIS2DE12 supply 1,8v / 3,3v
Hello,I have an issue with my LIS2DE12, when i'm starting up my board i'm doing the configuration of the device and then i need to put the boad from 1,8V to 3,3V to communicate with an other component. BUT when I come back to 1,8V the LIS2DE12 have t...
Resolved! LIS3DH offset correction
Hi,We've been using LIS3DSH for a few years now and are now searching for alternative sensor because of availability problems.In LIS3DSH there are offset compensation registers OFF_X(Y,Z) for fixing the read axle values with correction values stored ...
MP34DT05-A PDM Digital Microphone for Data Acquisition
hello,Can I use MP34DT05-A PDM digital microphone to get sound DB data on STM32G431RBT6 ？
the accelerometer value exceed the scaling boundary after long time performance of the device.
I have developed a firmware in sensortile.box and I'm using accelerometer data(lsm6dsox imu sensor) for that specific application. The problem I encountered is that, scaling of the accelerometer automatically changed, because after the long time the ...
Resolved! H3LIS100DL: prevent interrupting sample to be overwritten/overrun
The H3LIS100DL has no fifo, and the ODR can be set to 400Hz. This would make it update the axes data each 2.5ms. I have programmed it to interrupt a mcu when a threshold is reached. This wakes the micro controller from deep sleep. Unfortunately it ta...
VL53L1-SATEL circuits question
Dear a ST engineer,I had purchased VL53L1-SATEL and evaluated the function with NUCLEO-F401RE and "VL53L1 Gui". I connected VL53L1-SATEL board to NUCLEO-F401RE board directly through some wires.However the GUI didn't recognize the connection of VL53...
