LIS2DE12 movement recognition (AOI-6D)
Hello !I'm currently confronted with a misunderstanding..First, What is a "Know zone" and an "Unknown zone" ? My idea about it is :"Know zone" : somewhere (direction or orientation) you know you are going to."Unknown zone" : Unknown direction or orie...
Resolved! IIS2DH Anti-Aliasing Low Pass Filter by Design in comparison to IIS3DWB and what are the resonance frequencies of each axis of the IIS2DH?
Hi,so far we want to compare several MEMS accelerometers and their specifications. From ST, two sensors are on our list, the IIS3DWB and the IIS2DH.For the IIS3DWB, the data sheet offers a frequency response curve at page 19 and regarding aliasing th...
Resolved! Counter after interrupt request doesn't enable if condition in main
Hello STM-Community,I'm fairly new to STM programming and I use an STM32 microcontroller with STM32CubeMX encountered a weird issue with my functions.I've got an IRQ, which collects data every interrupt. Similair like this:void HAL_GPIO_EXTI_Callback...

I was wondering If anyone could provide me with detail step as I am new to stm sensor
Resolved! STEVAL-STWINKT1 vs STEVAL-STWIN KT1B
We purchased late in 2020 an STEVAL-STWINKT1.Just learnt that this board has been deprecated and the STEVAL-STWIN KT1B is instead the recommended reference designCould you please let us know:if we have to stop using the STEVAL-STWINKT1if get it repl...
Resolved! ISM330DHCX - SPI driven by FPGA - some questions
Hi, I want to drive an ISM330DHCX by an FPGA using SPI. Due to the fast operation and the exact timing I can realise this way, a few questions occured.Data sheet fig. 6 details the SPI timing. There is no value given for minimum time for CS=HIGH, i.e...
STM32L452RE SAI microphone connection RX returns 0
I'm trying to get the SAI working in receive mode with a MEMS microphone, but when i try to receive data it only returns 0? Here is the SAI setup:saiHandle.Instance = SAI1_Block_A; // audio block A. saiHandle.Init.Protocol = SAI_FREE_PROTOCOL; sa...
How to read multiple IKS01A03 memory register with DMA over i2c?
Hi,I am currently working on DMA combined with I2C bus. I want to read acceleration data from IKS01A3 with HAL function HAL_I2C_Mem_Read_DMA(). I want to read at 6 different memory registers. How can I use that function to get it work properly? Can I...
