Solved

Hello everybody, I am new here so please let me know, if there is important information missing. Thank you already for you time! I set up a STM32U575I-EV board for communication with CAN. The STM Board, a PCAN-USB dongle and an Oszilloskope are connected to the bus. The Bus is terminated correctly with two 120 Ohm resistors. I use the HAL libraries to interface with the FDCAN peripherie. The jumpers from the eval board are set to connect PB9 and PB8 with the CAN transceiver and to disconnect PB8 from the USB-C PD-interface. To test the setup I send dummy frames (ID: 0x000, DLC: 1, Data: 0x00). The frame is visible on the Bus and also the ACK from PCAN is visibile. PCAN USB has a 200mV higher voltage on CAN High 0 level. Here is the dummy frame on the Oszi: As you see on the the screenshot, the ACK is there and even though I put only one message in the Tx-Buffer of the FDCAN, it retransmitted. Here is my code: main.cint main(void) { /* MCU Configurati

Hi all, I’m confirming whether the ST LSM9DS1 provides any on-board sensor fusion output (for example quaternion/Euler), or if fusion must be done on the host MCU. If anyone has definitive guidance from ST docs/support, please share. Thanks.

I used CubeMX to generate the "LoRaWAN_AT_Slave" example for the B-WL5M-SUBG1 board.I had some issues with it waking up from sleep and upon a few hours of debugging i found that the LSE Driver Config was set to LOW in the example application, but the datasheet recommends HIGH.Just letting other people with the same issue know and hopefully the ST-Team can fix the example configuration in future releases.

Hi, I am using the STM32L4 B-L475E-IOT01A board with Wi-Fi module Inventek system ISM43362-M3G-L44.I have seen the example WiFi projects but they do not have the .ioc file. So my question is, is there any middleware available in STM32CubeMX which can help me implement WiFi connectivity via USART? The communication interface between the stm32 board and the WiFi module is SPI3 by default but the documentation says that use of USART3 is also possible, and USART3 is what I want to use.So any easy ways to do that? Any available middleware in CubeMX? Or is any example project available online?Thanks!

I am currently evaluating microcontroller options for our project and need your support in identifying a suitable MCU.Our key interface requirements are as follows:   2× MDIO interfaces,3× I2C bus interfaces If you could recommend an MCU that supports these features or share any relevant technical details/datasheets, it would be very helpful.If not, please also suggest alternate part numbers that can meet this requirement.

As mentioned in the title already, the file core_cm4.h is not contained in the recent version of  https://github.com/STMicroelectronics/STM32CubeG4 anymore.Selecting the v1.6.1. in that repo the file is contained. Looks like there was an error genererating the new version.

I am a fan of STM32, especially the peripheral sets offered are great. Over the years however, one type of peripheral is missing which would be a great help for many projects, this is a programmable logic cell.Such a cell would contain elements like Flip-Flops, Look Up Tables and such that can be configured for specific functions. For instance using the LUT's, it would be possible to create all kinds of logic operations like AND, OR, XOR gates.Using the Flip-Flops, I would be able for instance to create a clock gate, which I needed in my last project. There I needed an external clock signal to propagate to other peripherals and be able to enable/disable this. In the end I manage to create this function with a timer but this unfortunately generates something like 9 clock cycles of latency limiting the maximum frequency of the external clock signal. A basic Flip-Flop solution would probably introduce a much smaller latency.Competing products offer this kind of functionality more and more

Hi ST Community,I am new to ST and hope to find a fast solution on this way. Background:I am working on a hobby project and want to drive a BLDC Motor. Once I flash the SW on the target, Overcurrent Protection is hit immediately (can see on debugger and Motor Pilot (in MCSDK). Target: Custom Board based on EVSPIN32G4 Schematic (EVSPIN32G4)Chip: STM32G431VBx3. Workflow: 1.) Board Designer done over Motor Control Workbench2.) New Project created and .ioc file generated3.) Generating the Code over MX Cube (without touching any config)4.) Start Motor Pilot or Debugger -> results in overcurrent protection (PWMC_OCP_Handler() is triggered immediately and OverCurrentFlag is set to true.) My Assumption:1. It is not an HW issue because I removed the Motor from the Board so there can no big current flowing.2. I can see in MX Cube that not all of the Pins are configured from MC SDK, is that normal? Do I need to configure the missing pins (only related to motor con

Hi,I just noticed that CubeProgrammer v1.21.0 always shows me an update notification, but it is already the latest.Restarting the Cubeprogrammer or the operating system does not make any difference. Environment:- Windows 11- I have installed v1.21.0 alongside v1.20, but that should not make any difference, or would it? 

I am currently designing an NFC reader PCB based on the ST25R3916B. Could you kindly share the recommended PCB stack-up configuration and the routing guidelines for the NFC antenna? I have also attached images of the PCB layer stack-up that I am currently using. Could you please review them and confirm whether it is appropriate?

Good morning everyone! I have a fast question related with STPMIC1. I want to use it in a design with a STM32MP135 but I don't clearly see how to do it, specially the DDR rail, because I understand that i have to program it. But, in a 20-30 units production, How can I flash it? Is there a special tool to flash it by i2c? Or i should to make other solution in PCB?Thank you so much!PD: I need STPMIC1D (used in DK EVAL Board)

Following the tutorial here, at step 8, I get to the part where you load firmware onto the dev kit, but I always get an error "No ST-Link detected".  As far as I am aware, programming should be done over the USB cable, or UART, not ST-Link?The board is running Linux OK, UART terminal is working, so is IP over USB cable.  The run configuration I have is show below.  What am I doing wrong?I checked with STM32CubeProgrammer and there are no programming interfaces available over USB or UART, and no ST-Link..

Since there is no caregory to post for the MCU Finder tool I'm posting here. On Windows, the stand-alone app, as well as the Android app, do not show any content when filtering by the H5 range in the series field. Could this please be fixed? It's been like this for multiple months now. Thanks.

Hello — please help with the following questions about parameters:How should I correctly configure the TCXO frequency parameter $PSTMGETPAR,1245 (TCXO Frequency)?How should I correctly configure the CPU clock speed parameter $PSTMGETPAR,1130 (CPU clock speed)?To improve PPS accuracy, is it correct that the CPU clock speed should be set equal to the PPS Clock?What are the maximum supported values for the PPS Clock and for the CPU clock?

Hello, I am beginner with STM32.I have some radiosonde boards with an STM32L051R6T6. I use STM32CUBE IDE V2.0.0When I start a project, select the appropriate MCU, there is no Core directory and no ".IOC" file.So, it is impossible to access to the GPIOs.I've tried some ways to do that and allways unseccessfull. Please, have you an idea ? NoticeI use also an STM32F103C8T6 board.  I've create my own GPIO lib, my own I2C lib,  and I can compile, flash, debug and run my program. Thank you and sorry for my english  Retired 

Hello,I'm using the STM32N657 on a new project, and its not clear how users are supposed to setup GPIOs that are used in different domains (FSBL, Application, ExtMemLoader).  For example I am using pin PN12 as a LED output and defined it in FSBL.  Why doesn't this definition carry over to the other domains, and how can I get CubeMX to carry it over to the other domains? thanksMatthew

I'm planning to use ImGui as framework for creating a GUI application on the MP257 processor.The ImGui is bloat-free e.g it only uses the GPU hardware (OpenGL, Vulkan, etc...) to visulize the graphics such as buttons, menu, labels etc.Will an application like this work smoothly in MP257?

Hello,I'm developing an application with OEMiRoT and trustzone for STM32H563.I'm getting a write protection error (WRPERR) when I try to erase a secure flash sector from secure code that is not protected neither by write protection or HDP. I'm using the method HAL_FLASHEx_Erase() and I mapped the region as readable and writable with the memory management tool of CubeMX.If I try to do the same process without the secure boot provisioning, everything works as expected. I would like to know if there are any additional operation in order to write/erase flash at runtime when secure boot is used.Any help is really appreciated!Thank you,Giulio

I would like to refer you to the following post from @JRuss.4 that was never satisfactorily answered:STM32L4 Standby Mode GPIO State {Schmitt Trigger} Clarification from Reference Manual I also have the exact same question.   Here is my version of the question boiled down to a couple of sentences:The STM32l4 series reference manual, RM0394 (Rev 5 - the latest available), on page 158, states, "In the Standby mode, the IO’s are by default in floating state. If the APC bit of PWR_CR3 register has been set, theI/Os can be configured either with a pull-up (refer to PWR_PUCRx registers (x=A,B,C,D,E,F,G,H)), or with a pull-down (refer to PWR_PDCRx registers (x=A,B,C,D,E,F,G,H)), or can be kept in analog state if none of the PWR_PUCRx or PWR_PDCRx register has been set."This is confusing.  The statement "In the Standby mode, the IO’s are by default in floating state" contradicts the statement, "or can be kept in analog state if none of the PWR_PUCRx or PWR_PDCRx r

I've STM32G474 using the HRTIMER to control a boost converter, each channel has it's own converter. This all works nicely with the deadtime, no issues. When I come to do a pulse skip, (set CMP3 to 0) the deadtime is still being inserted in the the Tx2 output even though Tx1 output is not being pulsed! Is this normal or have I missed something? I've tried a few things to not make the deadtime happen, like disabling the set and reset sources... the only thing that fixes the problem is to also set the falling deadtime to 0 and then subsequently resetting it back to the required value. Tx2 has no set or reset sources configured.

Hi,I would like to know where I can find the SPI controller version of the STM32G491.AN5543 lists features depending on the SPI controller version and says "To identify the version and the available feature set refer to the product reference manual and datasheet". However, I was not able to find this info in the RM or datasheet of the STM32G491 or anywhere else.
