I am trying understand the sampling rate of lis3mdl on the Z axis. The datasheet has only stated on setting the ODR of X and Y but not Z. Only the performance of Z can be set. During testing, I have noticed that the Z axis sampling rate is slower tha...
Dear ST,I am using the ISM330DLC gyro and accelerometer,In the electrical connection mode 1 I have a pin called VDDIO.In my application I connected this pin to 3V but, I don't have any idea what is the use of this pin?Thank you for explaining
I have a MMC5603NJ (i2c addr 0x30) connected to SDx and SCx on LSM6DSOX with INT2 pin grounded. I can see with logic analyzer I2C transactions on BOTH the Slave and Master interface, but every time I try to access a register in MMC5603 on Master bus...
Hello,I am integrating multiple sensors from ST, all of which are connected to a central processor via I2C. Occasionally, I find that the LPS22HB is unresponsive at boot up. When the central processor attempts to read the WHO_AM_I register, there is ...
I am bit-banging since my CPU doesn't have native SPI compatible with the LIS3DH.To initialize the chip, I write:0x57 to Control Register 1 (DATARATE_100HZ, XYZEN) {see pic CR1Write.jpg}0x80 to Control Register 4 (BLOCKDATAUPDATE, SCALE_2G) { see pic...
My application hopes to detect objects on a flat surface (e.g. table). I hope to place the VL53L1X in a vertical plane, close to the horizontal table top. Then I hope to be able to ignore reflections from the table itself by using the RoI feature. I ...
Dear ST hello,I have a question about the bit field,I am using the stm32F429 discovery board, and I am working on the gyroscope Mems.if I declare a union like this:typedef volatile union { uint8_t All; struct { uint8_t Yen:1; /*X axis enable*/ ...
I have the STEVAL-MKI224V1A with the LPS22DF pressure sensor. This is attached to a STEVAL-MKI109V3 motherboard.I downloaded and installed the UNICO GUI version 9.14.6.0 The GUI app opens as expected and I select the "Environmental Sensors" on the le...
Dear Sir,Here set XL ODR = 104 Hz and Gyro ODR = 104Hz, routing XL data-ready to INT1, Gyro data-ready to INT2, respectively.Interrupt mode is set to pulse mode here.Do reading XL register and gyro register on INT1 and INT2 for clearing data-ready i...
