LSM6DS33 SDO always low
I am interfacing to an LSM6DS33 with an ST32F407using the SPI bus. The SPI is set up as follows: Fully Duplex Master Eight Bit Clock is high when Idle Data sampled on second edge Baud Rate P...

Use LIS3DH on the same SPI bus as an EEPROM, is it possible?
Posted on May 06, 2014 at 17:18I'm planning to use a LIS3DH on the same SPI bus as an EEPROM.But in the datasheet it says the LIS3DH CS pin is selecting SPI or I2C.So is it possible to use SPI to the EEPROM when LIS3DH CS pin is high (the LIS3DH wou...
FSM#14: How to… test your FSM: basic PEDOMETER, the last algorithm example - Part 2
Here below the second part of the algorithm describing the basic PEDOMETER. The picture here below shows the second and last part of the related FSM code: it is dedicated to recognize when the debouncing phase is over (n INCR command), and to count t...
HTS221 with Half duplex SPI
Hello,I'm currently programing a self designed sensor node with a HTS221. I've decided to use SPI to communicate with it (SPI half-duplex master)Here are the settings:static void MX_SPI2_Init(void) { /* USER CODE BEGIN SPI2_Init 0 */ /* USER ...
Unicleo-GUI not starting
Hi,i've installed Unicleo-GUI to test X-NUCLEO-IKS01A2 MEMS but the GUI is not starting. In addition i have installed latest Qt5+MinGW64, AlgoBuilder and STM32CubeMX with Firmwares. I see the Unicleo-GUI.exe popup in Windows Process Explorer and afte...
Resolved! Lowest power mode for accelerometer application in STM32L4 ?
Hi, I wanna use the lowest power mode possible for my stm32l432kc. I want MCU to wakeup on accelerometer motion (which is possible since the accel generate interrupt on motion). I've read in MCU appnopte AN4621(page 13) that i2c is detected only in s...
FSM#13: How to… test your FSM: basic PEDOMETER, the last algorithm example - Part 1
This example describes how to set up a finite state machine to enable the built-in detection of a basic PEDOMETER. The picture here below shows the first part of the dedicated FSM code (tomorrow the second and last part will be published). A human st...
Resolved! How do I save the temperature in a log from the LIS3DH through Unico?
I have a LIS3DH sensor and Unico 7 in my computer and I am using the evaluation board MKI109V3. The thing is that I want to save the temperature data (measured by the Embedded Temperature sensor inside the LIS3DH) in a log file and with Unico this is...
Can someone with internal knowledge confirm that the LIS3DSH in I2C mode never drives the SCL line low and that a standard "single master push-pull SCL" can be used in combination with the bidirectional SDA line.
The LIS3DSH datasheet contains the following text (not very clear):"If a receiver can’t receive another complete byte of data until it has performed some other function, it can hold the clock line, SCL LOW, to force the transmitter into a wait state....
What does COUNTER_BDR_REG1?
Hi,I am using LSM6DSO and I am trying to implement the FIFO feature. I am reading from here (https://www.st.com/content/ccc/resource/technical/document/application_note/group0/56/95/d6/a1/34/4c/49/6d/DM00517282/files/DM00517282.pdf/jcr:content/transl...
