Is it possible to get a single "sample" from a MEMS microphone using the PDM2PCM on an STM32? I'd like to take a single sample instead of reading in 16+ samples during one conversion... How would this be setup?

Resolved! LIS2DTW12 I²C/SPI mode selection

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...

Resolved! LIS2HH12 and IIS2DLPC two's complement temp compared

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_...

Resolved! LSM303AGR SPI operation

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 ...

For LIS3DH 3-axis accelerometer, what is the CS input pin's maximum input leakage current spec?

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...

Resolved! What is the temperature sensing accuracy of the LPS22HH for less than 0C?

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 ...

The magnetic sensor of STEVAL-MKI173V does not enter the data ready state by I2C communication.

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_...

Resolved! BMI055 interrupts problems

Hello,I am writing a code to initialize the BMI055 IMU on my STM32F765. To do so I am using the HAL libraries to enable the SPI connection through DMA and the drivers provided by Bosch: bma2x2 and bmg160.The two sensors work perfectly when only one o...

Resolved! Examples Operation codes for commands for LS3DSH

Hi,I can't find any examples of using commands in the statemachines.I want to create a tilt sensor, by using 2 statemachines, 1 is monitoring x axis, the other z axis.To keep it simple i will add the code for the x axis only . This statemachine setup...
