I need to connect X-NUCLEO-CCA02M1 with NUCLEO-401RE and I would like to use I2S. I understood that I need to use a double-clock for the I2S and a clock for the expansion board because I need to read data from rising and falling edge of the clock, bu...
I'm looking at UM2128 (en.DM00337036.pdf), "Getting started with Unicleo-GUI for motion MEMS and environmental sensor software expansion for STM32Cube", also known as "User Manual". The Revision History shows that it was updated 20-May-2019, so it sh...
Hello,I have an issue with the pressure sensor LPS25HB. It looks like the LPS25HB don't work properly when the rest of the circuit drain current from the coin cell.I confirm it is a problem related to the powering of the pressure sensor LPS25HB : Whe...
Hello,I made a new PCB design using the LPS25HB (see PCB prints attached). On this new PCB, the LPS25HB works fine when I put a new coin cell (I get correct pressure value to compute a height difference of 50cm so I use the sensor at its maximum perf...
We are using the LIS3DSH to sample acceleration data on all three axes at 800HZ. No state machine or advanced features are used. The following registers are set on initialization:CTRL_REG4 = 0x87 // 800Hz, all axes enabled CTRL_REG6 = 0x50 // fifo an...
I am using MP34DT05 to calculate the A-Weighted output and for this I want to understand the sampling frequency of the sensor.
Hi, I would like to know what factory calibration procedure has been performed on this sensor and how are the calibration values used behind the scene? More specifically, there is a temperature compensation enable bit in the register map; I would lik...
Hi, I am working on ASM330LHH IMU module. And I want to understand process or steps to get IMU alignment and calibration information.I have following queriesIMU is kept in board which can be placed in any orientation. Now, I do not know whether the X...
Hi team,I use LIS3DH communicating with MCU over SPI. LIS3DH is used in current critical application. I use ST library to get access to registers. I use Low-Power mode with 1 Hz sample rate and expect to get current draw ~2uA, but instead i get ~27u...
Do you have an I2C routine that can read two byte at a time like OUT_X_L and OUT_X H or a read routine to reada all three values X<Y and Z (6 bytes) ? I am not using HAL, i am using CMSIS.
