Dear Sir,​Generally speaking, the coordinates of the g-sensor on the PCB board have an angular deviation from the world coordinates. Assume that the coordinates of the g-sensor are (Xs, Ys, Zs) and the world coordinates (X, Y, Z) have alpha, beta and Theta angle relationship.If we have a g-sensor orientation as following,How to convert (Xs, Ys, Zs) to (X, Y, Z)?It is confused because when Xs, Ys point to gravity direction, it is positive, while Zs point to gravity direction is negative.Could we have a rule to follow?Thanks.

I have an accelerometer located in an arbitrary position on a car. As the accelerometer already has a coordinate system by default, I want to find some method that allows transforming the data I have from the sensor and aligning them with the coordinate system of the car.When the vehicle is stationary on a flat, horizontal surface, use the three components relative to g-sensor, Gxs, Gys and Gzs(Gxs is the g value obtained on g-sensor Xs, the Gys and Gzs are g component relative to g-sensor Ys and Zs) and make rotation can rotate the Gzs aligned with gravity direction and Xs-Ys plane parallel to with horizontial. But how to align the Xs to vehicle X-axis?In theory, the euler angle can be obtained by rotating the coordinate axis of the G-sensor three times, and use this conversion matrix for conversion. But In practice this is not feasible.Is there any simple way to aligning the coordinate systems of accelerometer and vehicle?Thanks.

Hello,I'm trying to send data and retrieve the output from my stm32f4-DISCO. I'm using a python based code and specifically stm_ai_runner. The code is rather simpler but I can't access the board because even runner.summary() doesn't work. My board is flashed with the network :And this is what my code looks like :And the terminal : I thank you in advance,Numa

I saw multiple resources on different conversions between chips, such as AN5094 (between F3 and G4), but I can't find anything for G4 to F7.Is there a step by step process to follow that has a program do most of the work, something similar to MCSDK, but with an already generated project?

Hello, do you have any application on the use of variables:execution rateCut-off frequency

I have acquired both boards. Here is the link to the video:https://www.youtube.com/watch?v=FSIYaWOmzS4

The FreeRTOS debugging tools (as present in Atollic, NXP MCUxpresso, etc) seem to be missing in STM32CubeIDE. These include task view with stack use, semaphore/mutex view, queue view. Those of us using FreeRTOS need these!What's going on? Are available as a plug-in somewhere?Thanks!Best Regards, Dave

I am integrating the cube programmer API into some end of line production test. I've been able to use the API for loading firmware images, and I can prepare a board for OTP programming by loading TFA and uboot, but I can find no API support for programming OTP on the MP1 parts, am I missing something or is this absent from the API? How is this done within the programmer CLI tool? (i.e. how to the OTP commands function, what API calls do they use so I can replicate some of this functionality)I can't easily use the existing programmer CLI to automate since I'm working with 6 boards still on a panel prior to breakout, and the CLI (and API) doesn't handle multiple connected instances well when repeatedly executing programmer CLI commands as the USB device instance seems to change and I need to be sure which boards I'm programming unique values to (e.g. MAC address / serial number etc)It would be really useful if ST followed NXPs lead and open sourced their programming tools so we could sor

Hello Community,I would like to receive and transmit the data via FDCAN.However, I cannot find the real pin on the STM32h745/50 Discovery Board.The Microcontroller pin of FDCAN1_RX is PH14, PA11, PD0, PB8, and PI9.The Microcontroller pin of FDCAN1_TX is PB9, PA12, PD1, and PH13. However, the pins cannot be found on the STM32h745/50 Discovery Board.So, how could I use the FDCAN1,2 pin and function...?

I implement the eeprom emulation library for the STM32F423 controller and was wondering if the variables are 16 bits can I use the virtual addresses like this: uint16_t VirtAddVarTab[NB_OF_VAR] = {0x1, 0x2, 0x3};Or do I need to keep space like 0x1, 0x3, 0x5 because the variables are 2 bytes wide?

I am trying to use the HAL_PWREx_EnableSRAMRetention() function described in UM2319 Description of STM32G0 HAL and low-layer driversI am using STM32CubeIDE, with my project configured as a STM32 project (with .ioc file for managing software packs, etc)Problems I am having:UM2319 - Description of STM32G0 HAL and low-layer drivers doesn't seem to contain any information on how to actually download and access the extension driver that it is documenting.STM32CubeG0 MCU Firmware Package does not contain the PWREx driver (wrong)I cannot find PWREx driver listed in the STM32CubeIDE Embedded Software Packages Manager (see screenshot below)Google searches on this topic have been frustrating - I just get a whole bunch of UMXXXX pdf user manuals for different STM32 MCUs --> I need the driver!Help please?

I am working on a PCB design with a STM32H735IG uC, and I would like to use the integrated SMPS to provide VCORE directly, without the LDO. This corresponds to figure 19.2 of RM0468 (the reference manual). In this configuration the VFBSMPS is connected directly to VCAP and to VDDLDO (I also add 100nF on each of the three VCAP pins and on each of the three VDDLDO pins).  Section 6.4.1 ("System supply startup") stipulates that at startup:When the system is powered on, the POR monitors V DD supply. Once V DD is above the POR threshold level, the SMPS step-down converter and voltage regulator are enabled in the default supply configuration:The SMPS step-down converter output level is set at 1.36 V.The voltage regulator output level is set at 1.0 V in accordance with the VOS3levelSo, at startup, before the LDO is disabled by software, there is a conflict on the VCAP pins: the SMPS is driving them at 1.36V, while the LDO provides 1.0V internally. Is this out of spec? Is the LDO going to

I followed the steps to install the mongodb from the openSTLinux distribution.when I run the mongodb from the terminal, it is crashing with the bus error.root@stm32mp1:/usr/bin# mongodBus error (core dumped) Appreciate your help..

Hi everyone,I have been stuck at a problem. I have been trying to configure HAL_Delay function to work in STM32 BLE_Server example in the STM32WB SDK. However, for some reason, the code gets stuck inside the HAL_Delay() Function. I have searched over the internet and tried the solution to increase Systick interrupt priority. Still there's no solution to my problem. Please help me out.

Hi,I have a project which is based on the STM32L475RC and now I want to upgrade to the STM32L475RE controller. I have changed the device from STM32L475RC to STM32L475RE in options for the target of the Keil environment. But the new project based on the STM32L475RE is not working. Any other steps to change the project configuration?

Hi, newbie here, while browsing the Examples for the NUCLEO-WL55JC1, it came to my attention that some have a dualcore version. The SubGHz_Phy_PinPong for Example.Does one core get disableled in the non dualcore Version? And how can i change the setting? Greets, Daniel

 

Hello All,I am in the process of designing a circuit with four microcontrollers in Daisy chain. I would like to program and debug them via one JTAG port, hence will be daisy chaining them. Which one of the programmers can do this?. I have used ST-Link-V2, but this cannot programm multiple chips in a daisy chain.

Hello,My team is developing a product that integrates the LSM6DSM and IIS2MDC, and we would like to use the MotionFX library for sensor fusion. How can we accomplish this, given that we are using a third-party ARM Cortex M4F processor (not STM)?I have already tried integrating the MotionFX library with our project. Though it compiles and links successfully, our MCU throws a hard-fault within MotionFX_initialize.Thank you,Peter

Hello,I am interesting in STLQ020PUR WITHOUT the output discharge function (presented as an option) : there is no information in the datasheet to recognize if this option is present or not versus the device reference STLQ020PUR : how to be sure that the provided device has no discharge function ?Thanks

Hi, Is there any way to give a more meaningful name to a serial port with the device tree, so that is shows up in the linux kernel?Right now, in a device tree, it is possible to choose an alias in the alias node. But they do show up as ttySTMx in the /dev directory.Is there a way to make it work so that it gets a more intutive name like rs232? For my specific layout some serial ports are connected to a specific interface./ {   aliases { serial1 = &usart1; }; }; /*root*/ // Instead / { aliases { rs232 = &usart1; };   }; /*root*/

Hello. I'm currently implementing USB Drag and Drop Bitstream loader for FPGA using STM32F103CBTB and latest CubeIDE (1.10.0). The implementation uses STM32 in USB Mass storage class and virtual file system based on FAT12. The part of Drag and drop is working fine. But If I add 200ms delay into the code (line 354) which is under STORAGE_Write_FS() in usbd_storage_if.c , This cause USB to halt. So, my question is there any way to pause USB transaction for 200ms delay and continue transaction? I attached the source of usbd_storage_if.c down below for who want to take a look at. Thank in advance!
