 Hello, I am in the process of planning and testing the STM32mp13 Line.We have equipped our project board with the STM32mp13 CPU, but we encountered an issue when trying to connect it via St-link; it did not establish a connection.The St-Link version we are using is V2. Could you please provide a response? SL1

Hi everyone,I bought a display Riverdi display (RVT70HSSNWC00-B) with a STM32H757XIH6 microcontroller.I want to setup the FDCAN but without success.Has anybody already done and could send a sample ?Thank you in advance.

I downloaded the STM32MP151AAC3 example model (.zip file) that routes traces to the DDR3L memorySTM32MP151A - MPU with Arm Cortex-A7 650 MHz, Arm Cortex-M4 real-time coprocessor, TFT display - STMicroelectronics Then I measured DDR_Q1 to DDR_7, DQM0, DQS0_P and DQS0_N and filled the Excel table that is included inside the downloaded .zip file.Here is the result:I have been using Altium CircuitMaker (very similar to Altium Designer).I measured by first pressing CTRL+H and then mark one part of the track and then I press this button.But when I look at the Excel spred sheet that ST have made, they show me these numbers.My question is: What are ST doing to getting the length of DQ0, DQ1, DQ5 and DQ6 ? It seems that they are the only ones that differs. Others seems to be similar. If they are changed in the model, but not in the Excel spred sheet, which values should I follow? The values made by ST, or the hard ware example model made by ST? The reason why I'm asking this ques

Hey, Is it possible to build a CAN-FD bootloader in STM32G474RE? @STTwo-32 @mƎALLEm 

Hi ST tesam,When I use  HAL_SMBUS_Master_Receive_IT( ) to receive data from device ,I can not got the information directly after the HAL_SMBUS_MasterRxCpltCallback( SMBUS_HandleTypeDef *hsmbus ) was complete.(I had set a flag when HAL_SMBUS_MasterRxCpltCallback( SMBUS_HandleTypeDef *hsmbus )  done)I had to wait for a while and then I can read data from register, but what can I do to know when the saving process was complete? Regards,LSN

Hi !An application I am working on has a PC connecting to an ethernet device (currently through Ethernet) and a STM32 (STM32G0B0CET6) through USB.I am looking to only have one connection to the PC through USB, hence I am looking to have the incoming USB plug into a hub, going to the STM32 on one side and a USB-Ethernet bridge on the other. All devices are self-powered (not through USB) and the STM32 does not have to talk to the other device at all. The USB hub I am looking at is Microchip's USB2412.I am mainly wondering if there is a "standard" way to make sure the STM32 will enumerate fine through the USB hub as I am not too familiar with USB. It looks like the hub has pins that can signal that it is ready and enumerated, and it looks like downstream devices should only boot after this is the case in order to enumerate. Perhaps it would be possible to instead hook this signal to the RESET pin on the STM32 ?Thanks a lot in advance ! Best regards,Adrien

Hi. I'm using STM32U585 with OV5640 to capture the image. I set the DMCI synchronization to hardware to us Hsync and Vsync. However, I set the camera to send JPEG image rather than raw image, so the frame size is unknown. Now the problem is that it's not possible to use the frame_event to capture an frame. because the way I see frame_event, it's fired when the buffer size that we specified when we start capture is filled. which might contain several and half image. So, I have to use Vsync_event. What I can't find out is how to know how many bytes has been transferred when the Vsync_event has happened. The dcmi is using linked list dma. My question is:How can I read how many bytes has been transferred by the DMA? where should I look at?Kind Regards,Milad

Hi~ ​I'm trying to connect uart bootloader. but there is something wrong. I can't connect bootloader via STM32CUBEPROGRAMMER​and I found the datasheet that STM32F401 NUCLEO-64 only support one uart for system memory.​ I connect Uart1 (PA9, PA10) I've already checked that Uart1 is working on user FW ( I have tested )I connect BOOT0 and VDD ( I have checked 3.3V )I checked BOOT1 is grounded.I press the reset button.I think STM32F401 NUCLEO-64 is on system memory boot. (cause I programmed blink led , when I press the reset button, it stopped) I am trying to connect uart via STM cube programmer program.but it shows error message that "Error: Activating device: KO. Please, verify the boot mode configuration and check the serial port configuration. Reset your device then try again... "I used HSI clock which it presented on datasheet.I checked that bootloader FW version , it is D1, ​I don't know what's wrong with this.any Ideas??is that possible to using uart bootloader with STM32F401 NU

Dear community members, I am following the tutorials from ST via: https://www.youtube.com/watch?v=4Vn_cRUfRag&list=PLnMKNibPkDnEju3j_qhe-MFK-NnwD_kuP&index=7&ab_channel=STMicroelectronics I am currently using SPC58EC but when I load workspace from UDE STK 2021 in windows 10 it said that:Message from component 'PpcJtagTargIntf' :Can't connect target !Message from component 'PpcJtagTargIntf' :No JTAG client found !Please check:- target power supply- JTAG cable connection- target configurationEventhough I already enabled load VCP and reinstalled with UDE STK 5.02.04 but it still can't connect target. Whenever I press retry, my board flashed a green LED D5. I upload the log file as well as device manager and error pics. Please help me.Any help would be very much appreciated.TH. 

Hello. I'm trying to obtain CRC value from CRC peripheral. It's supposed to give me 8 bit number. Instead it gives me 32 bit number. What am I doing wrong?

Hello, I'm trying to get Zigbee working on my STM32WB55CG6 custom board. I've verified that the RF section works since BLE works perfect but now I'm trying to get Zigbee working. Since there aren't alot of examples I've tried the Zigbee_OnOff_Server_Distrib but the chip is not the same so when I tried to program it I bricked the STM32.Now my question is if there is an example for the STM32WB55CGU6 in which I can connect it to Home Automation something like this example: https://www.youtube.com/watch?v=W2oB4AmUKr0 but for the right chip.I would appreciate the help, I also shared my project files below

Hi,I'm working on a STM32H755BIT6 with a custom PCB layout, which uses direct SMPS supply hardware configuration.I'm migrating an existing Keil project which was created with STM32CubeMx 6.7.0 to STM32CubeMx 6.11.1 and I discovered that the option PWR_DIRECT_SMPS_SUPPLY is now unavailable.I wonder if this is a bug from CubeMx software or if it was remove on purpose to force user use another hardware configuration? Thanks! 

Hi there, I'm trying to configure a CubeMX project, starting from scratch, for a custom board based on a STM32MP153CAC3. And I'm having an issue with the MPU clock setting. In particular, I can't select any MPU Clock Mux option and see the PLL1 tree as not editable:  Is it normal? Do I have to change something to unlock the configuration? It seems very strange to me that I can't change the MPU clock! NOTE: used CubeMX v6.9 and v6.11, standalone version, same result. Please help me :) Thanks 

Hello everyone,Hello @Martin KJELDSEN , I have read all the posts in the community, thats with this topic relevant and tried to do the same thing in this post.I could reversed the screen with 180 degree, except the buttons they staying on the original position. Even when they are clicked then nothing happens.The post above is few years ago and i don't know if there is some updates to this subject. Otherwise i muss flipping all the screens in the designer.Regards,Mahdi_____________________________________________________________________________Before flipping:After:but the button is not touchable.

Hello,I made 2 project about client and server using stm32wb1mmc product. > server project is using "custom p2p server"It works well but I want to improve usability. 1. How to reduce scan time for connect client to server?  > I quote it from examples. use "CFG_TASK_START_SCAN_ID" when external pin interrupt is set.    so when button is pushed, client start scan request. after 10s appx, client can be connected server.    I want to reduce this time. 2. How to enter sleep(stop) mode cpu2?As far as I know, cpu2 can't enter stop mode after cpu1 & cpu2 booted completely. If it is correct, is it no way to cpu2 enter sleep and wake up? I attached 2 project files.best regard.

Hello,I added the RFAL software library to my existing wireless charger project.When I set totalDuration to 50U, there are cases where it cannot detect the card. I get better results when I set totalDuration to 25U. Will it cause problems if I reduce the value of the totalDuration parameter in the library for NFC/RFID card detection? What is range for totalDuration parameter? How should I adjust it?

After updating Cube to v1.5 for my STM32H5 project (Nucleo-H563ZI), the ethernet stopped working except during the initial run after a load of the firmware with the debugger.  After a reset, either POR or via the debugger, pings to the board fail.  When I checkout an earlier version of the code that uses a Cube v1.4 .ioc file, and bypass the migration to v1.5, the ethernet behaves normally.  Has anyone else experienced a similar issue?

Hi team.I develop a code, employs read the ADC value from the LDR and transmit the ADC value serially by UART, and glow the LED if LDR value goes above 1400. It is work fine up to hardware level. Now I update the value in the HTML page using Ethernet. I will be able to send only the ADC value to web page, I unable to send the LED STATUS to the web page. In the ssi_Handler function the iIndex value execute only the Case 0:(ADC_Value update), it does not update the case 1:(LED_Status) value. I attached my code below, please guide me to what type of error I was made. the code has 3 parts1. main.c2.ssi.c3.shtml codethe first part of the code 1. main.c/* USER CODE BEGIN Header */ /** ****************************************************************************** * @file : main.c * @brief : Main program body ****************************************************************************** * @attention * * Copyright (c) 2024 STMicroelectronics. * All rights reserved. * * This softw

I want to realize a scroll bar in ScrollList.So the scroll bar will work like process bar. And it will tell my user where the current icon is.Is there any clever way to realize it.In addition, can I customize the scroll bar?

I want to program my STM32WB55VG-Q6, but have been getting 'No ST-Link Detected'. I was using a Nucleo board previously and the ST-Link works fine with it. I am able to debug and flash the program onto the Nucleo but not on the STM32WB55VG-Q6 board.  

Hi everyone, I am trying to use an accelerometer with my STM32h745 board thought SPI.DO you have any idea where I can find library for thus accelerometers ?And how to use the SPI protocole with STM32H745 :)

Hi,I have custom developed board that uses STM32F401RCT6TR as MCU. I have LSM6DSLTR IMU sensor on the board and MCU is communicating with IMU using I2C1 channel (PB6 and PB7). I also have 2.4" screen (ILI9341) that displays IMU values and external EEPROM (on I2C2 channel) to store data. I am facing problem in I2C1 (PB6 and PB7) channel. Sometimes the sensors returns correct values, but most of the times it returns weird data. I think that my library is correct because I used same library in  my another board (that uses STM32F030) and it was working as expected. I have pull up resistors attached to the I2C lines. I also changed the MCU and IMU with new ones, but nothing changed and IMU not worked as expected.  I think it is sth related to my code. Could you please help me to solve this issue? I have attached LSM6DSLTR library and main code to this post.Thank you

Hi  I am using the module Lora-E5 which has the STM32WLE5J inside.  Looking at cubeMX , I can select LoraWan, but I want to only use the Lora side. Do I simply select the LoraWan, and use the Lora part, as it requires LoraWan key etc which I wont use. Best RegardsScott

Hello,I started a new design based on an STM32H745XI with a 480x272 TFT screen.I have some experience with TouchGFX with a previous design on an STM32H7B3 with the same screen but this development is stucked at the TouchGFX 4.17 revision.My problem is with images stored in a non mapped external flash (an eMMMC in this case). I setup the bitmap cache as usual using the registerBitmapDatabase call in my TouchGFXConfiguration.cpp file as this : // Use the section "TouchGFX_ImageCache" in the linker to specify the placement of the cacheLOCATION_PRAGMA("TouchGFX_ImageCache")uint16_t imageCache[2*1024*1024/2] LOCATION_ATTRIBUTE("TouchGFX_ImageCache");void touchgfx_init(){Bitmap::registerBitmapDatabase(BitmapDatabase::getInstance(), BitmapDatabase::getInstanceSize(), imageCache,sizeof(imageCache),10);I implemented the blockCopy function to detect address ranges in the ExtFlashSection and provide the copy from eMMC to RAM but this blockCopy function is never called in normal run ...
