Posted on July 25, 2017 at 20:35LIS3MDL doc says take 16 bit signed Temperature Register values, divide by 8, and add 25 degrees C. I get a value that is always about 11.5 degrees warmer than what the ASM330LXH on the same board is reporting, and...
Posted on July 23, 2017 at 16:54Hi all , I used BlueNRG-MS found a problem , the MCU is freescale chip and used SPI communcation with BlueNRG-MS , but the MCU send the configuration information to BlueNRG-MS , start I could read 0x04 0xFF 0x03 0x...
Posted on June 13, 2017 at 14:08I am working with IIS2DH accelorometer an I would like to configure single/double click tap detection. For that, I have done following configuration:I2C_WriteByte(&ctrl_1,1,0x5F); I2C_WriteByte(&ctrl_3,1,0x80); I2C_W...
Posted on July 17, 2017 at 08:22hello, I have gone through the datasheet and app note of LIS3MDL. But i am not able to get how block data update bit work i.e. if someone has set the BDU bit and if I read registers through I2C one by one, then how th...
Posted on July 19, 2017 at 14:30I have done following configuration to detect double click. I am able to detect double tap but it is consider four times.I2C_WriteByte(&ctrl_1,1,0x5F); I2C_WriteByte(&ctrl_3,1,0x80); I2C_WriteByte(&ctrl_6,1,0x82); I2C...
Posted on July 18, 2017 at 10:45Hi, I am working with LIS2DE12 accelerometer, I want detect any new data is updated to temperature and x,y,z axis registers.can any one provide steps for configuration.
Posted on July 17, 2017 at 16:25Hello,I try to read acceleration values from a LIS3DSHTR using the STM32F091 �C. I use SPI with DMA to read the values but I have trouble with the incoming datas in the RxBuffer.On my two screenshots you can see the b...
Posted on March 29, 2017 at 12:47Hello STM!I am facing a new goal: I want to build my own diferencial beamforming 2 MEMS PDM microphone array to achieve kardioid directivity pattern.So i need to get data out of two MEMS mics simultaneously ... i mea...
Posted on July 14, 2017 at 07:24The magnetometer on my device has different scale and offset on its axes.This is because of influence of hard iron on the board. So, it needs to be calibrated. I've read https://my.st.com/resource/en/design_tip/dm0028...
