Hi st frends:  Yestarday I fuse the OTP PKHTH as followBut today I found  the key I fuse is not the correct one. So I want to re-fuse the OTP ，it seems that can't no fuse again.  is there any way to fuse the OTP this situation? 

I'm using STM32H733VGT6, STM32F030CCT6 and LTE module. As show as attached picture, it is conneted via UART. I want to recieve data through LTE and connect STM32H733VGT or STM32F030CCT to DFU to download firmware. Is it possible with UART? STM32H733VGT have USB DFU, but I want to use UART. Are there any circuits or materials that might be helpful?

Hi Team, Do you have any MCU/MPU that supports UHF RFID reader/writer?I see the ST25RU3993 was into this category, but becomes EoL. Do you have any replacement for the same? Regards,Jenitt 

Hi,I have used TouchGFX on an F4 without any problems so far, except that the animations were a bit slow. Now I bought this H7A3ZIQ and when I add TouchGFX to the project, I get 230 'undefined reference' errors. Any ideas on how this is possible?

  I am trying to find out whether is it possible to send 64bytes of data in one frame of Multiframe in CAN FD. i.e First frame will have 64 bytes, Consecutive frame will also have 64 bytes in STM32G0B1KBU6 basically in G0 series MCU

Hello, I'd like to know if ST could provide software package or any tutorial to realise the Vibro-Acoustic Sensor Fusion demonstrated in this video https://www.youtube.com/watch?v=bi4NenlnR-k? I have an STEVAL-STWINKT1B on hand. Thanks in advance.  

Hello everyone,I'm currently working on a project using the STM32H723VE microcontroller and have encountered a problem with the SAI1 peripheral. Previously, I developed my code on the STM32H723ZG Nucleo and everything worked perfectly, including the SAI1 callback function. However, after writing the same code to the STM32H723VE, the SAI1 callback function is no longer triggered. All DMAs are configured in circular mode with word data width.What works on the STM32H723VE so far is the SAI4 in slave transmit and the I2S1 in slave receive. SAI4 accesses RAM D3 and I2S accesses RAM D2 while sending/receiving data from DMA.As soon as I include SAI1 slave transmit data in the code, all DMA operations of SAI4 and I2S1 stop. As soon as I stop the DMA from SAI1, everything works again.I am confused because the code worked fine on the STM32H723ZG Nucleo.Here is the RAM allocation for the DMA in the .._FLASH.ld file:  .dma_d2_buffer : /* Space before ':' is critical */ { *(.dma_d2_buffer)

With the newest CubeMx version 6.11.x, when selecting oversampling, a ratio is being set, and this ratio is a define, which are in "ADC_VER_V5_V90" that is not being set when a new project is created. #if defined(ADC_VER_V5_V90)#define ADC3_OVERSAMPLING_RATIO_2 (LL_ADC_OVS_RATIO_2)#define ADC3_OVERSAMPLING_RATIO_4 (LL_ADC_OVS_RATIO_4) #define ADC3_OVERSAMPLING_RATIO_8 (LL_ADC_OVS_RATIO_8) #define ADC3_OVERSAMPLING_RATIO_16 (LL_ADC_OVS_RATIO_16) #define ADC3_OVERSAMPLING_RATIO_32 (LL_ADC_OVS_RATIO_32) #define ADC3_OVERSAMPLING_RATIO_64 (LL_ADC_OVS_RATIO_64) #define ADC3_OVERSAMPLING_RATIO_128 (LL_ADC_OVS_RATIO_128)#define ADC3_OVERSAMPLING_RATIO_256 (LL_ADC_OVS_RATIO_256) #define ADC3_OVERSAMPLING_RATIO_512 (LL_ADC_OVS_RATIO_512) #define ADC3_OVERSAMPLING_RATIO_1024 (LL_ADC_OVS_RATIO_1024)#endifThis gives an error in the adc.c file as:hadc1.Init.Oversampling.Ratio = ADC3_OVERSAMPLING_RATIO_4;The "ADC3_OVERSAMPLING_RATIO_4" is missing/undeclared.

I'm trying to use touchGFX with an ILI9341 using SPI. I've gone through the steps to create my timer to call touchgfxSignalVSync() but I get the warning: implicit declaration of function 'touchgfxSignalVSync'.  Is there something that needs to be included in order to call the method?I'm using STM32CubeIDE Version: 1.15.1 Build: 21094_20240412_1041 (UTC) and TouchGFX Version 4.24.0.Kindest regards

Posted on March 10, 2017 at 11:16Hi,The communication between single microcontroller and pc is works fine through ethernet tcp/ip . problem occurs only when i connect two microcontroller to a single pc via ethenet cable,Here d-link 5-port 10/100 desktop is used for multiple connection.when connection made for multiple microcontroller ,the communication doesn't work properly.Either one connection will be in active condition other will be inactive.I need solution to overcome this issue.My requirment is from pc it sends query to microcontroller-1 after receiving response from microcontroller-1 .It has send next query to Microcontroller-2.Process should be repeat.Is it possible? If yes please please guide me. Please anyone reply as soon as possible......Thanking You....

I was using the sensor until now on an Raspberry Pi with direct access to the I2C bus without problems.Now I use an FT260 USB-I2C interface to communicate to the sensor from a PC via USB. In principle the communication is working, e.g. vl53l5cx_is_alive() works as expected.But the initialization fails. On the poll for sensor booted status I now always get a 9 as the answer instead of the expected 1 until the timeout is reached.In the documentation I haven't found any hint what the value of 9 at this point means.This is the place where vl53l5cx_init() fails:  /* Wait for sensor booted (several ms required to get sensor ready ) */ status |= WrByte(&(p_dev->platform), 0x7fff, 0x00); status |= _vl53l5cx_poll_for_answer(p_dev, 1, 0, 0x06, 0xff, 1); if(status != (uint8_t)0){ printf("vl53l5cx_init(): Wait for sensor booted failed\n"); goto exit; } And inside _vl53l5cx_poll_for_answer() I see that the returned value is 9. Because the expected value is 1 _vl53l5cx_poll_f

within the STM32 Cube IDE After creating a hex file, I noticed that some lines had less data than others due to linker separation. How can I use the STM32 Cube IDE to add dummy bytes to the memory? 

Hello,I am working on H750 while the flash is limited.Because the LCD is RGB565, may I know if the the unrelated functions can be removed? such as functions related with ARGB8888 and RGB888.  Thanks.   

I built a custom board and attempted to program it using both the ST-Link Debugger V2 and an STM Dongle, but I'm encountering issues and can't seem to program it successfully.Could anyone suggest what the problem might be?

E.g. the FatFs_USBDisk sample does not have a *.ioc file.Maybe not all example projects use STM32CubeMX?(the issue sounds like https://community.st.com/t5/stm32-mcus/creating-stm32cubmx-ioc-project-for-older-stm32cube-firmware/ta-p/49664)How can I enable the view "Device Configuration Tool" for that example project?Or: what's the best way to see the Mikrocontroller resources used by that project?Reason for asking:I can't add support for serial console (including DMA) to FatFs_USBDisk from a reference project. There seems to be a clashing of using the resources.

I'm using an area of Flash in an STM32U5 to store some information that I need to retrieve connecting the board to the SWD port. Data is sent out using the ITM port. All is working as expected connecting the board using the STM32 Cube Programmer, allowing to save data to a file. The CPU can be run and halted.By setting RDP1 this is not possible anymore. Once the board is connected the CPU is locked and I found no way to run the firmware. I suspect this is the normal behaviour to protect access to the Flash, is this correct? I couldn't find specific information on the manuals. Or is there a sequence to have the firmware run when connected to the programmer?I also expect that there's no way to exclude an are of flash from being protected by RDP.

Hi all,when running the same piece of code (math operations with random access to RAM) on the CM4 of the STM32G474 we measure smaller execution times than on the CM4 core of the STM32H745.The STM32G474 is clocked at 168 MHz and uses the SRAM mapped at 0x20000000.The CM4 of the STM32H745 is clocked at 200 MHz (and its CM7 at 400 MHz) and uses AHB SRAM1 mapped at address 0x30000000. How is it possible that the slower clocked CM4 core of the STM32G474 is more performant? Any explanations? Thanks, Marco Accame, Ph.D.iCub Tech Facility, Istituto Italiano di TecnologiaCRIS, via S.Quirico 19D, 16163 Genoa Italye-mail: marco.accame@iit.it    

Not sure why my previous post was marked as spam:Hello,I'm trying to do something relatively simple but can't figure out the issue. It might also be possible that there is no issue and my expectations are wrong about timer synchronization. I am using TIM1 as a master with trigger out event configured when the timer is enabled. Enabling timer1 should start TIM2 and TIM15 (both configured as slave with appropriate ITR0 triggers). Just for debugging and simplicity all the timers are using the same prescaler and the same period (ARR register value is the same). The timer do start when I enable timer1 as expected. But they are not synchronized. Below are registers dump for tim1, tim2 and tim15 just before setting TIM1.CR1  enable bit. Once I set the enable bit I get the logic analyzer capture shown.I mean it works in the sense that enabling TIM1 triggers TIM2 and TIM15 but why aren't they synchronized?Here is the code. I am using HAL for simplicity but I did try dir

 Finally after a long struggle, I was able to get into the system memory by changing to CP2102 ttl wire. Now I have another problem. Any solution to fix this? The PCROP_PDP bit is unchecked also.

Hi there,  I am using multiple VL53L4CX sensors and the target is a person's hand within a 60cm range. I am wondering if there is a specific calibration method for a hand within a shorter range (60cm), to improve readings. Right now I am just using the default settings and using the STM32H755zi Any help is appreciated, thanks.  Isaac

Setup STM32WL55JC1 embedded on a custom PCB with other peripherals STM32CubeIDE Lora gateway - Multitech MTCDT3AC model with a built-in network server, join server, packet forwarder and gateway. STM32CubeWL f/w version 1.3.0 Application hangs because MBMUXIF_LoraSendCmd() command stuck on Sem_MbLoRaRespRcv sometimes I have an application built around LoRaWAN_End_Node_DualCoreFreeRTOS example provided in the firmware. My application on CM4 sends telemetry roughly every 4-5 minutes. It will run well for a few days and suddenly the MBMUXIF_LoraSendCmd() gets stuck waiting on Sem_MbLoRaRespRcv. Reading more on how dual-core system works I figured that if a response is not received through the IPCC channels, the semaphore is never released. This is a potential pitfall for me because my application requires telemetry to be sent continuously at the 4/5 minute rate. I cannot think of reasons why a Resp might not have been received by the CM4 core for any telemetry send Cmd. How to reproduce

Hello everyone, I want to measure the current consumption on a STM32WB5MMDK discovery board. I've found that I had to put an ammetre on the jumper JP1, and I programmed the RGB LED to be working. However, when I put the ammetre and I power my board, I found that the current is null, and I can't find why, even if I checked the schematics and the datasheets. I was supposed to have something around 100 mA normally.Does anyone know the reason of my problem ?   Thank you Nour

Hello all, I have not been able to get the DFSDM_AudioRecord example to work on STM32H735G-DK.I am using CubeFW v1.11.2 and Cube MX 6.11.1. Furthermore, I tried debugging and noticed that the DMA Callbacks for Half and Full complete are called. Then I checked the buffers to notice that the values in it were always, 32768. The example BSP, also does not playback any recorded audio (through MEMS loopback), but is able to play the stored audio. So, the Line-Out is working fine. It has to be the MEMS.  I wanted to confirm if the examples are configured correctly, or if something on my board is faulty.Can someone from ST or User Community please confirm that this example is working? 

Hello community,I’m encountering a challenging issue with my STM32 setup that I’m hoping to get some insights on. When I mount my microcontroller onto another PCB and connect it via USB, the board overheats near the USB connection and the LD3 (power LED) does not light up. I only soldered the 3V3, 5V, and GND pins on this secondary board, where 3V3 and 5V are used to power peripherals.Here are the symptoms:When connected to a PC via USB, the area near the USB connection on the extension board becomes very hot.The power LED (LD3) on the microcontroller does not turn on.Removing the extension board and powering the microcontroller directly via PC resolves the issue, and everything functions normally.My initial guess is that there might be a power supply issue or a short circuit involving the 3V3 and 5V pins used to power peripherals, possibly causing insufficient power delivery or overheating due to improper load handling.Could anyone provide guidance on how to properly manage power dist

HelloI tried to implement I2S on the chip in question to send the data acquired by the on-board ADC (I tried both 8-bit and 12-bit) with DMA active on a curved buffer and half-word data size. The data should be read by an ESP32, connected to it on the ws, bclk and din lines configured as I2S Master that provides the clock and the ws and that should momentarily only print the received data on the serial monitor. However, despite having set the I2S channel of the STM32 to 8Khz 16 bit only right with Philips standard, equating it to that of the ESP32, I do not get the expected data, I can print only zeros or numbers that apparently are not synchronous data. I also tried to transmit static arrays with predefined values ​​instead of the ADC to have a clear feedback on the receiving end but nothing. I wonder if the STM32G431KB core is the right board to do these tests or should I look at another model?     /* USER CODE BEGIN Header */ /** ***************************
