Studying the example application in the STSW-IMG 023 software I noticed that in the main.c file in the static void MX_I2C1_Init (void) function a clock speed equal to 1000000 (10 ^ 6) is configured, but if I go to the CubeMX file from where the proje...

Hi, I'm using a board which embeds two ST MEMS: ism330dhcx and lis3mdl. I'm exploiting the MotionFX Library to obtain quaternion and rotation. Which is the way to obtain accuracy regarding roll pitch and yaw. I want to understand how close is the val...

I would like to build an application on an STM32 microcontroller (the one integrated in the NUCLEO-L432KC) that allows to transmit a message of 192 bytes or more if possible on CAN BUS.At first, I was thinking of a mechanism that in the transmission ...

UPDATE: This fact is not present in 1.3.1, I checked again and I saw that in this case the I2C clock speed is set to 400k, but always in the CubeMX there is 100k. I have done some tests and have drawn some conclusions that I have yet to verify via th...

Hello John,thanks once again for your availability. Unfortunately, I did not understand your advice. With the function I mentioned earlier I get the ranging data inside a VL53L5CX_ResultsData structure with different fields. Among these fields there ...

Hi @John E KVAM , related to the VL53L5CX API in the X-CUBE-TOF1 package, I saw that effectively are the same as the ULD driver for VL53L5CX. I don't understand in which way they are used in the X-CUBE-TOF1 package. I will try to explain my doubt. T...

Which value for I2C clock speed in STSW-IMG023 Ultra Lite Driver (ULD) Example for F401RE?

In MotionFX Library, which is the difference between Heading and Yaw?

The MotionFX library provide me quaternion and rotation angles (roll pitch and yaw). It is possible to obtain the accuracy for these data from the Library?

Is there an API that allows you to send data greater than 8 bytes through the CAN communication protocol?

VL53L5CX. Regarding this sensor. Does The output obtained by invoking the function vl53l5cx_get_ranging_data() contain the raw data or does it contain data that are processed by some patented algorithm?

Re: Is the VL53L5CX ToF a good choice, considering all the Time-of-Flight sensors family realized by ST for detecting obstacles below the floor level such as holes or stairs?

Re: Regarding the MotionFX Library. In what order is the quaternion given??
