What does circular burst-mode (rounding) read from the output registers mean?

Hi,I am implementing the IIS3DWB vibrometer. There is a register that allows circular burst-mode (rounding) read from output registers. What does it mean?Thanks.

Resolved! IIS2MDC single measurement current consumption

Hi,We notice IIS2MDC have single measurement mode which can be used for one shot operation. The datasheet also mention how to calculate current consumption for such mode.However we can not find if the sensor will go sleep immediately after measuremen...

Resolved! Is the ODR of LSM6DS3 the same as sampling frequency?

Hello, I want to use a accelerometer which is LSM6DS3, and it's spec says that it's maximum ODR is 6600Hz.So I want to know is the ODR the same as sampling frequency?Or is it just out data rate? And is sampling frequency less than ODR? If so, what's...

How do I setup lis2dh12 interrupt for a specific amount of shock/impact?

What all interrupt registers do I need to setup for a specific amount of of shock for a specific duration?I specifically want to generate an interrupt when there is a vibration in any direction and should be able to tune the amount of vibration(thres...

LIS2DS12 Direction of the accelerations?

Use 3-axis acceleration LIS2DS12page 10 figure 2 Pin description in datasheetThe z direction is reversed in the output, but I don't know why.ex) Gravity acceleration is displayed as + g.

I am planning to use an HTS221 Temperature and humidity sensor in SPI mode. I wish to use it on a common SPI bus each device on the bus is enabled by bringing its chip select low.

when its chip select input is high, as it is supposed to operating in an I2C mode. Will the HTS221 data bus change into an output state and override the common SPI data?

LIS3DHTR returns 0xffc0 for all channels

I'm having some issues in trying to get valid data out of the LIS3DH. For some reason I am only receiving a constant value of -1 [0xffc0 10 bits left aligned] on all channels and FIFO slots. I can read/write all other registers just fine, it's just t...

LIS3DH sensor is giving me huge offset when just resting on a table.

While flashing the LIS3DH I accidentally commented out a block of code causing read/writes of unintended registers. Below is the code which caused it. static void read_accel(void){ uint16_t MOSI = 0xA9; uint32_t MISO; int8_t dataRec; uint8_t i = 0; f...

My PC after updating the Windows can't detect the STMicroelectronics Port of my sensor!

I really need your help!It is happening something strange here!I have installed the "VCP_V1.3.1_Setup_x64" in the last two months to connect with my hardware. and my PC easily was detecting my sensor and everything was working very fine. But on 19th ...
