Question about LSM6DS3h : why Accel Z value OUTZ_L_XL (2Ch) & (2D) become negative when module acceleration downward but not upside down.

2021-09-22
I am using this chip to get the X & Y angle of the unit. First read outOUTX_L_XL (28h) & 29hOUTY_L_XL (2Ah) & 2BhOUTZ_L_XL (2Ch) &2Dhand calculate Roll and Pitch.  The angles works good in normal / slow moving or stable condition. Also need to det...

Can LSM6DS3 measure absolute angle or Static angle?

2020-11-23
Dear Sir,Can we use LSM6DS3H measure a tilt angle referenced to Earth? It has 6DOF angular velocity and velocity measurement. Can we combined these 2, do some calculation to measure its tilt angle / static angle. Which mean when unit turn on or...

STM32L152 HAL libary - USART, - no TX transmission ?

2018-09-05
Dear Sir,Now I am using HAL library ( STM32Cube_FW_L1_V1.8.0)after setup USART 3, and after running, in some case, I need to disable the transmit interrupt by using__HAL_UART_DISABLE_IT(&UartHandle, UART_IT_TXE);But then if I need to re-transmit som...
