Hello, I am using my sensorTile STEVAL-STLKT0V1 with the firmware SENSING_V4. To collect the data, I connect my sensor via Bluetooth to the app and save the data to SD. Unfortunately, it happens to me that if I move the sensor too far away from my ph...
is there any alternate part where no redesign needed?
Hello, I haven't any experience with STM programming. So do you advise me to buy the STM WL series for sending my data? And do I need 2 MCU to transmit/receive the data? Or just an MCU with a receiver ( please note that my data needs to be taken as i...
Hello,I have loaded the SENSING1_V4 firmware on my STEVAL-STLKT01V1 sensor and I am using it with the ST BLE Sensor iPhone app, saving the data on the SD card. Since I would like to use two sensors simultaneously, I wondered if there was a way to do ...
Hi all,I use Arduino to read the LIS2DW12 sensor. The circuit of sensor was as below.According to the circuit, the I2C address was 0x18. But when I use Arduino to scan the address, sometimes it has no response. Has any connection I miss?To read the ...
It appears to be a 2's complement left justified value. But making it simple, how do I convert this data... say for a start:au8_l_Data[0] is the low byte returned from the MEMS (OUT_X_L)au8_l_Data[1] is the high byte returned from the MEMS (OUT_X_H)T...
Hello, I am attempting to build an ultrasonic microphone for predictive maintenance applications. I have produced a flex circuit per ST's Application Note: 5522. I have not, however been able to pick up ultrasonic signals. What sort of output(voltage...
Hi, I'm LeeI'm using the "LSM303D", "LIS3MDL", "L3GD20HTR" chips to make a drone.I would like to know the effect of the"LSM303D", "LIS3MDL", "L3GD20HTR" chips on the magnetic field and electromagnetic waves generated when using a drone.I am wondering...
There are many options for choosing the timing constant for RMS when using FFT. How to choose the right one? Why is the purpose of the timing constant for RMS? Please advise. Thanks!
Hi, Can the time domain output of FFT calculation from MotionSP be speed (mm/s RMS), not acceleration on Y-axis? Please advise. Thanks!
