I have set PB0 and PB1 as EXTI. Also set pin PB2 and PB3 for EXTI inturrupt mode as well. But for PB0 and PB1 interrupt never occurs whereas PB2 and PB3 always working perfectly. What could be the issue. I have attached the sample code below. Can someone please help?/* USER CODE BEGIN Header */ /** ****************************************************************************** * @file : main.c * @brief : Main program body ****************************************************************************** * @attention * * Copyright (c) 2023 STMicroelectronics. * All rights reserved. * * This software is licensed under terms that can be found in the LICENSE file * in the root directory of this software component. * If no LICENSE file comes with this software, it is provided AS-IS. * ****************************************************************************** */ /* USER CODE END Header */ /* Includes ------------------------------------------------------------------*/ #include

Reference documents: STM32H755 reference manual - RM0399, ECC implementation guide for STM devices - AN5342I have been implementing a handler for errors triggered by RAMECC on an STM32H755 Nucleo dev board. Testing of the handler has been conducted by initializing RAMECC interrupts and error latching  (monitor specific, the "global interrupts" are not enabled to maintain control on a per monitor basis) and then reading uninitialized memory regions until an interrupt is triggered.In my testing, all of the 32 bit regions, the AXI-SRAM and ITCM-RAM behave as expected - the word offset is latched into the FAR register, and the 1 or 2 32 bit words are latched in the FDRL and FDRH registers as appropriate (FDRH is unused in the 32 bit memory space). Correctness of the FDRL and FDRH registers can be verified by examining the memory that is referenced by the FAR offset (this offset points to a word not a byte, so it needs to be scaled to get the byte address - see AN5342). If a double bit

Hi,I make a project with touchGFX Designer 4.21.1, I place a gauge but the display show only the indicator without needle.I try with a default indicator in library.with simulator is currect. screenViewBase::screenViewBase(){   __background.setPosition(0, 0, 480, 480);   __background.setColor(touchgfx::Color::getColorFromRGB(0, 0, 0));   add(__background);   Centro.setXY(-120, -101);   Centro.setBitmap(touchgfx::Bitmap(BITMAP_OVERLAY_ID));   add(Centro);   gauge1.setBackground(touchgfx::Bitmap(BITMAP_ALTERNATE_THEME_IMAGES_WIDGETS_GAUGE_MEDIUM_BACKGROUNDS_ACTIVE_ID));   gauge1.setPosition(128, 173, 240, 240);   gauge1.setCenter(120, 120);   gauge1.setStartEndAngle(-113, 112);   gauge1.setRange(0, 100);   gauge1.setValue(50);   gauge1.setNeedle(BITMAP_ALTERNATE_THEME_IMAGES_WIDGETS_GAUGE_MEDIUM_N

Hi, I need to control Stlink form python code.1) On some PC I am not able to connect with STLink to my MCU - I tried STM32CubeProg and ST-Link utility. The Error is  UR connection mode is defined with the HWrst reset mode.But why on the same PC the STM32CubeIde can without problem load the program to the MCU? What kinds of "API" STM32CubeIde use? I want these API - because always works!I have not connected RESET pin - but it should not be problem hope2) On the PC when I am able to connect to MCU VIA STM32CubeProgrammer - I also can use STM32CubeProg cli interface to conrol it via python. But is not there something different? Because STM32Cubeprogrammer is too large (about 700 MB on disk?) I also tried ST_Link utitliy - cli, but it was not much reliable.Thank you very much.

The datasheets front page mentions "Reader/Writer" as operating mode, but later only mentions " NFC-A / ISO14443A reader mode". Could you confirm that ISO14443A writing is supported?

Hello,I work for an engineering department. For an new development, I want to discover STM32H5 family to nkow whether cryptographic capabilities are suitable for my project.I tried to learn with the wiki by ST, a learning section uses exactly the same microcontroller for the security parameters. Unfortunately the page is down. It's possible to have this exercise or the good URL to access at this page?Best regards,

I'm using motor profiler for the motor control. I have the following hardware components:STM32 Nucleo-F4446REX-NUCLEO-IHM16M1Mitoot motorIn the motor profiler, it mentions that IHM16M1 can only work sith STM32 Nucleo-G4 and that F4 and IHM16 combined is not supported. Is there a workaround available to test the motor despite this limitation?"

I can link the MotionMC library in the Nordic project and build it successfully. However, the MotionMC_GetLibVersion function is not assigning the version pointer.

I have integrated Micro-ROS into the m4. I have it working such that I am able to publish sensor data and receive it from other nodes. However Micro-ROS takes up a quite a bit of space, 70+ KB. In their documentation it is target at mid tier micro controllers. I am trying to add the parameter server and that pushes the .text over the 128KB limit. I am wondering if it is possible / advisable to recompile the system image to allow for larger text space for the co processor. I believe their are some changes to make to the device tree memory section among other places. My possible options I see would be:Rebuild the system image to increase memory for the M4 and make the other requisite changes to increase the size of the .text spaceDon't use micro-ROS on the m4 and exchange data via packets and a smaller implementation by hand and parse the data on the A7 side to publish it into the ROS2 world.Optimize everything as much as possible to reduce the size and try to keep squeezing it into the

Following the tutorial on How to customize the Linux kernel I made steps as below:Create a custom layer.Add it to the build configuration in bblayers.conf.Create a fragment.config with bitbake menuconfig and put it into my-layer/recipes-kernel/linux/linux-stm32mp/5.15/ as the kernel version is 5.15.Create a my-layer/recipes-kernel/linux/linux-stm32mp_%.bbappend file as advised in the tutorial:FILESEXTRAPATHS:prepend := "${THISDIR}:${THISDIR}/${PN}:"   KERNEL_CONFIG_FRAGMENTS:append = "${WORKDIR}/fragments/${LINUX_VERSION}/fragment-custom.config" SRC_URI:append = " file://${LINUX_VERSION}/fragment-custom.config;subdir=fragments "It seems that the kernel configuration wasn't applied at all, is there something that I'm doing wrong? Without the FILEXTRAPATHS line, the file couldn't be found, yocto didn't look into my-layer at all.

Hello, I'm using STM32H743ZIT6 and have question about DE mode and HSD/VSD mode. In my LCD datasheet is MODE pin with which I can select mode:What are difference between them? If I use DE mode I do not need to generate VSYNC and HSYNC?

Hi,We have written the data in Flash Bank 2 sector 7 successfully. Power cycled the board and trying to read the stored data from Flash Bank 2 sector 7 and found Hadrdfault error at 64th byte.-> The data stored in the form of char.-> Using HAL library to for flash read and write Following image represents the memory layout before reading the data. At 64th byte String had "?" and leading to Hardfault error. Even tried the Flash Bank 2 sector 1 and found the same error.Quick response is much appreciated. Regards,Srinidhi H

My application uses an sx1262 LoRa sub GHz transceiver. I need an MCU which has very low power consumption as well as high performance efficiency. In that case which option will be the best? Is it to choose a lower power series MCU and add an extra transceiver or use STM32WLE5x MCU which has an inbuilt transceiver?

Hello,Looking over the STSpin implementation of the Clarke Park transforms and SVM has raised some questions about the derivation of the transform. Typically the the Clarke Transform takes the form of:𝐼𝛼=𝐼𝑎𝐼𝛽=1√3(𝐼𝑎+2𝐼𝑏STSpin's implementation effectively rotates the Beta component by 180 degrees with a sign flip:𝐼𝛼=𝐼𝑎𝐼𝛽= -1√3(𝐼𝑎+2𝐼𝑏)Next, the Park transform usually takes the form of:𝐼𝑑=𝐼𝛼∗cos(𝜃)+ 𝐼𝛽∗sin(𝜃)𝐼𝑞=𝐼𝛽∗cos(𝜃)−𝐼𝛼∗sin(𝜃)Where as STSpin seems to rotate each dq component by 90 degrees by using the opposite trigonometric functions on the alpha/beta vectors 𝐼𝑑=𝐼𝛼∗sin(𝜃) + 𝐼𝛽∗cos(𝜃)𝐼𝑞=𝐼𝛼∗cos(𝜃)−𝐼𝛽∗sin(𝜃)Considering Beta is negative in the STSpin Clarke, it seems that Iq is actually equal to Id in the "correct" Park transform. Does anyone have an explanation for this?Separately, the SVM seems to be empirically 120 degrees out of phase with an SVM implementation from this paper. Is this to compensate for the different reference frame

What are the settings in the attached picture?When a can interrupt comes in, are you setting whether to receive it through core 2 or core 0?

On stm32u5xx HAL_PWREx_EnterSHUTDOWNMode will not work when a DMA is still active.The fun part is, that after a uart dma transmit, the DMA transmit enable flag is not cleared due the undocumented define  USART_DMAREQUESTS_SW_WA.What's the reason behind  USART_DMAREQUESTS_SW_WA?Is their a way to unset  USART_DMAREQUESTS_SW_WA through CubeMX?

Hi All,Microcontroller running on 2Mhz clock speed, UART is configured at 115200 baud, Transmitting is working fine but facing issue while receiving data by interrupt, UART error occurred but not showing error number(huart.error =0, NO frame error, parity error, no overrun error). If i use lower baud rate its working fine,I want to know why this behavior?​
