On about 15% of the boards in my latest production run I am able to access the accel/gyro registers over the I2C bus but cannot access the magnetometer registers. As a simple test I am trying to read the WHO_AM_I register (0x0F) for both. I get the...
Will I get meaningful data if read the registers without any register modification or do I have to set the registers first. Sorry I'm very new to ST products and I would like to incorporate into my product.
Hello,I am trying to get the STEVAL-MKI109V3 upgraded to support the STEVAL-MKI179V1.When I first tried to use the 109V3, Unico said my firmware was out of date and needs to be updated to support the 179V1.So I used Dfuse to update the part. I am usi...
I try to use the LPS22HB as real pressure sensor (measure of force against the skin, but I almost didn't see any change. Only when press with big force I see the change.Does the name of barometer mean it can't sense pure pressure against its window?
If I want to test the LPS33HW and I already have the X-NUCLEO-IKS01A2 motion MEMS place over STM32 Nucleo test by DataLogTerminal SW from X-CUBE-MEMS1 package.I see there is LPS33HW EV STEVAL-MKI183V1. But I didn't see any reference to use it on the ...
I'm having a nightmare trying to get my LIS2DH to respond. SA0 is high, CS is high.It kind of responds to the right address (others get nothing), but data is all zeros.All I want to do is get XYZ data out, these are all zeros too!The I2C timing chart...
We are testing VL53L1X Time of Flight Sensor with STM32L072(B-L072z-Lrwan) controller. Within 200cm the range measured by sensor is accurate. After 200cm we are getting a lot of variation in the range is measured by the sensor. We have to change the ...
Hello there,can anyone tell me the difference between these both MEMS accelerometers? Based on the data sheet, it seems that both sensors are identical.Thanks in advance!Best Regards,Pascal
When I read any of the axis output registers with SPI (OUT_X_L etc), it appears the MISO line is held high after the read. This causes a sustained high power consumption on my CPU after the read. If I read any other register type after reading an out...
