STM32F4 Discovery I2C LIS3DSH Problem

I have tried to work with LIS3DSH sensor using I2C protocol. I applied procedures on STM32f manual. But it didn't work. I wanna just receive x axis value. According to this, The GPIOD-12 will be on if it is less than 20. Maybe ı could not realise its...

Algobuilder with ArmCortex M0+ Nucleo

Hi!We are using AlgoBuilder with the NUCLEO-L476RG and it is working pretty nice. We wanted to try out our AlgoBuilder application on an Arm Cortex M0+ board to evaluate power consumption and behaviour. From what I saw from the documentation it seems...

Resolved! What is the advanced feature of the pull up at pin SA0 of IIS2DH?

We discovered that the SA0 Input of the IIS2DH of your accelerometers has a very high pull up current.The pull up is about 40 kOhm at IIC adress select line input. If engineers will use two IIS2DH in there design.Than the IIS2DH at adres 0x18, mea...

I am using the LIS2DH12 and get expected values in normal mode. When changing to high res mode the scaling is not as expected.

FS=11, BLE=0, LPen=0, HR=0 (10-bit normal mode, +/-16g FS). I expect the sensitivity to be 48mg/digit, and sure enough, if I right-align my 10-bit value and divide by 48 I get a value of about 1054 on the z-axis.When I set HR=1, no other changes, I e...

Resolved! H3LIS331DL precision / default calibration

Without any move, my H3LIS331DL on a MKI153V1 kit, and read from and STM32L4 MCU, gives values around X=1,5 / Y=2 / Z=3 G at 200g full scale.Is that "Zero Offset" normal ?Should I do anything to get values closer from 0 / 0 / 1

Less number of samples collected than the sample rate used

I am using Lis3DSH at 1600 sample rate . I am using I2C at frequency 250Hz for communication with sensor.If I want to capture 3 seconds data(4800 samples), the actual time taken to complete this procedure is more than 3 seconds, which means overrun i...
