LSM6DSV80X gyro offset
I am using the LSM6DSV80X to get roll-pitch-yaw from SFLP and gyro reading. I noticed that the sensor keeps reporting increasing yaw and increasing offset for X axis while at rest even though the data sheet suggests that it should have up to only 1dp...
STHS34PF80 Presence and motion sensor
Hello, In my case, the STHS34PF80 sensor module is powered using I2C communication with the ESP32 module, and I have tested its functionality only up to 2 feet; beyond that, it fails to detect any presence. However, the datasheet indicates th...
Resolved! LSM6DSV16X: Inactivity sleep duration values discrepancy between "LSM6DSV16X" & "AN5763"
Hi,My question is in regard with SLEEP_DUR of the register WAKE_UP_DUR.Datasheet "LSM6DSV16X" (p98) mentions:Duration to go in sleep mode. Default value: 0000 (this corresponds to 16 ODR) 1 LSB = 512/ODR_XL time"Whereas the "AN5763" (p60) instead spe...
Resolved! STATUS_REG of the ASM330LHH
How long does the TDA bit in the STATUS_REG of the ASM330LHH remain “1”?Is the TDA bit itself a latch type and remains “1” until the temperature output register (OUT_TEMP_H/L, 21h/20h) is read?
Resolved! ASM330LHH CTRL9_XL DEVICE_CONF
It is recommended that CTRL9_XL DEVICE_CONF in ASM330LHH always set this bit to 1 when configuring the device, but when should it be set back to 0? Should it not be set back?
Resolved! LIS2DW12TR weird artifacts (or maybe incorrect processing of data???)
Hello, I am working on interfacing with a LIS2DW12TR sensor over I2C. I currently am able to read/write registers, and am working on processing the data coming out of the fifo. I currently have the following: int read_LIS2DW12TR_buffer(int x[32], i...
Resolved! LSM6DS3 SPI Bug?
Hello, I use an AT32F403A MCU to connect LSM6DS3 IMU via SPI 4-wire, then I read the WHO_AM_I register at 0x0F. According to the datasheet, the return value should be 0x69, but the chip returned 0x44. Then I repowered the board, and the value seemed ...
Resolved! IIS2DLPC- Tap threshold
Hi,I'm trying to use the least possible threshold for IIS2DLPC tap detection.Is it achieved by setting TAP_THSX[4:0] as 00000b or 00001b?I see that 1 LSB corresponds to FS/32. Does 00000b means the threshold is 0g or some fixed value?If the threshold...
Resolved! What is the SPI mode of the gyroscope sensor I3G4250D?
I use the KIT STM32F411 DiscoveryWhen I choose:SPI CPOL: LowSPI CPHA: 1 EdgeIt works But when I choose:SPI CPOL: HighSPI CPHA: 2 EdgeIt does not work Could you explain why? Thank you!
