I am trying to validate a new board layout and am looking for the minimal configuration to read accel data.I'm using SPI. When the WHO_AM_I register of the LSM6DSR is queried, the correct response of 0x6B is returned.I take that as validation of the...

Posted on February 06, 2018 at 16:45It is my understanding that the LSM330DLC is a 'System-In-Package', that is it is a separate accelerometer and gyro die packaged together. What are the actual die part numbers?The reason I ask is that the LSM330DL...

Yes, I looked before asking.The problem turned out to be the SPI driver. It was deasserting Chip Select to soon and the device was not being configured correctly.

Is that black line just above C3 silk or a break in the ground plane?If it is the latter is there a large loop area making C3 and C44 ineffective?The via in the pads of the discretes can cause thermal imbalances that lead to tumbestoning during assem...

"Have you already looked at our design tip DT0058?"Yes.Actual source code would be more useful than making everyone of us reinvent the wheel.

I just went through this yesterday for my LSM6DSR part, so had this information at hand.It is from the STMems_Standard_C_drivers repository.git clone https://github.com/STMicroelectronics/LIS2DH12-PID/That will contain:/*** @defgroup LIS2DH12_Sensiti...

Are there any parts in a matching 14-LGA from any supplier so a new layout is not required?
