Question #1:In my system, I have 3.3V available, so I was planning to use that for AVDDVCSEL & AVDD since it is within the range but the I2C interface will run at 1.8V.The 1.8V seems fine from a Vih/Vil point of view. My concern is around IOVDD and 2...
To set the wakeup thershold, I use WAKE_UP_THS and for single-tap I use the same functions as the example (https://github.com/STMicroelectronics/STMems_Standard_C_drivers/blob/master/lis2dw12_STdC/example/lis2dw12_tap_single.c). Morever, I set 0x0110...
Hello, I'm using the FusionFX library(V2.5) to calculate quaternions and therefore estimate an object position. I'm using an X-NUCLEO-IKS01A3 that has the LSM6DSO (ACC + Gyro) and LIS2MDL ( Mag). I'm using an 16G scale in acc and 2000dps in the gro...
I want to read LIS2DTW12 data using SPI which is also shared with another device, can I use the LIS2DTW12 CS pin as chip select and operate devices one by one.because according to the LIS2DTW12 datasheet:State of CS1: SPI idle mode / I²C communicatio...
Hi all,I'm currently deploying hardware that can have either the LIS2HH12 or IIS2DLPCAccording to the datasheet the LIS2HH12 stores the temperature as two's complement / 11 bit / 8 digit per degrees celcius.So I convert it this way:int16_t tilt_read_...
Posted on March 01, 2018 at 11:24Hi,I am struggling with moving from the obsolete LSM303D sensor to the LSM303AGR sensor.I had the LSM303D sensor working correctly in continuous mode with the STM32F1 processor using 4 wire SPI mode.But I cannot get ...
I have a battery-based application, so I want to minimize power, by selecting the largest-valued pullup resistor on the CS pin, that will guarantee a high on the input.I cannot calculate this without knowing the maximum input leakage current on the C...
Hello, according to the datasheet for the LPS22HH, in Table 3 the temperature sensor operating range is -40C to +85C. Further down, it specifies that the temperature sensor absolute accuracy is +/- 1.5C from 0C to 80C. What is the accuracy from -40C ...
Wrote 0x40 to the CTRL1_A register, wrote 0x8C to the CFG_REG_A_M register.I was able to read the data on the accelerometer via I2C communication, but the magnetic sensor cannot read it.How do I change the "Zyxda" bit in the magnetic sensor's STATUS_...
