The LPS22HB has an absolute pressure range of 260 - 1260 hPa. It's possible for the 24-bit pressure output value to fall outside that range. A value < 0x104000 is below 260 hPa, and a value above 0x4EC000 is above 1260 hPa. What should I do with a...
I am trying to connect this microcontroller to Unicleo, but on Unicleo it says that it cannot detect any suitable ports. However on the device manager of my windows pc I see that it is connected as a virtual com port. Is there a step that I am missin...
I used the step counter of LIS2DH12 and MMA8542 to make a comparison. I found that LIS2DH12 is a bit slow. For example, we use a step machine to test the bracelet of MMA8542 in 8 hours. The test has more than 60,000 steps, while the number of steps t...
Hello, everyone, we found that the working current is too high during the use of the LIS2DH12 sensor. The current is as high as 290ua. According to the specification, the high resolution of 100Hz is 20ua. The working current is much higher. I...
Hello, I followed this : https://www.st.com/resource/en/application_note/dm00628155-how-to-use-a-sensor-on-a-dil-24-socket-in-xcubemems1-package-applications-stmicroelectronics.pdfand created an STM32L476 Nucleo project for ISM330DHCX DIL 24 daughte...
I found Zephyr drivers for 3 different LSM6* devices. These are LSM6DS0, LSM6DSL, and LSM6DSO. My board has, as you probably guessed, an LSM6DS33. I was hoping that one of these could be used, or that one of them could be adapted. Any knowledge to sh...
I have a question about the high-pass filter mode configuration. With the configuration at 0x00, it states in the data sheet that the high-pass filter mode will be in normal mode in which it will be reset by reading the REFERENCE register. Assuming t...
In our application, the LPS22HB has ODR=1Hz. Every 10 seconds the pressure is read from the device and converted to millibars. The pressure is generally around 990 mbar, and data collection is done over hours of time. At random times, the pressure...
Hi,how to differentiate both chips, if they have the same value for WHO_AM_I register?I know that I could read couple times the accelerometer values, calculate magnitude over all axis and check if the value is near 1g or 0.5g (assuming no movement du...
I am looking for accelerometer ultra low noise with low g.I want to connect 4 sensors using I2C, so I need 2 pin SA0 and SA1.Do you have such sensors
