Solved

hi its been months since i started my journey with the ethernet port i need to communicate via UDP to a pc to get data from the board and send i succeeded some times where some of my projects worked for a while then stopped sometimes the board doesnt ping at all the problem is that i work on this project on and off not continuously so i tend to forget what i did every last time now it's not pinging or nothing i tried following the https://controllerstech.com/stm32-ethenret-2-udp-server/ tutorial and it just worked then stopped if any of you succeeded with the udp server please help and thanks in advance

@Community member​ What works:Using STM32CubeIDE 1.6.1 and created a .ioc for the F750 I have used the library with arm_math version V1.4.5 b in my previous project with the STM32F750 without a problem, adding __FPU_PRESENT and using ARM_MATH_CM7 using hal drivers. I don't have any libraries linked. and it compiles and FFT works. Intruction set is THumb2, Floating point Abi-hard, unit = FPv5-D6. using 9-2020-q2-update GNU tools for STM32 toolchain. GNU11 ISOC11 compilerWhat does not work:Using STM32CubeIDE and created a .ioc project using the STM32L072cz. I am trying to include the same DSP CMSIS library to do a little vibration anaysis. The exact same settings except for no FPU and FPU uinti is Software and I am using ARM_MATH_CM0PLUS .In Release compile I getError __SSAT already definedIn file included from ../Drivers/CMSIS/DSP_Lib/Source/TransformFunctions/arm_cfft_f32.c:41:../Drivers/CMSIS/DSP_Lib/Include/arm_math.h:666:25: error: redefinition of '__SSAT' 666 | &nbsp

Hello,The datasheet for STM32WLE5xx states, that this series is capable of OTA firmware update, however I am not able to find any resources on how do perform it. The only document that shows up is the AN5554 application note on firmware update over the air (FUOTA), but it's only applicable to dual-core STM32WL55xx series, and not single-core STM32WLE5xx.Is there an error in the datasheet? If not, I would greatly appreciate any pointers/resources on how to perform OTA for STM32WLE5xx series.

I have a strange issue. I used the SDIO Interface on a F2 and a F429 without issues. But on the first usage with the F446 i run into a strange problem.With the Logic Analyzer i am observing the communication.Card Init:Requesting Card Type, CSD and CID works well over the CLK and CMD Line.While Switching to the 4Bit Mode i'm getting wrong feedback via the Data line. In detail there is a problem with the FindSCR function still in 1Bit Mode. SDMMC_CmdSendSCR is send out correctly. The DPSM is reacting correct to the Data0 lines response. Flags a set correct for 2 32Bit words but SDIO_ReadFIFO() will only give zero as feedback.Log Sending SCR: Response: static uint32_t SD_FindSCR(SD_HandleTypeDef *hsd, uint32_t *pSCR){....   if(__HAL_SD_GET_FLAG(hsd, SDIO_FLAG_RXDAVL))   {       uint32_t data = SDIO_ReadFIFO(hsd->Instance);       printf("copy tmp[%u] = %u\n\r", index,data);&nbsp

It gives this message - Device specific model "SPC574S64E3" not supported! when I tried to edit the pinmap. Is there way to edit the pin map. what component i should install

i would like to output my sensor data by USB, it seems that is it places into a .dat file but how is it encoded ? or it is possible to get the value directly?

I have a STM32L031G6 component in a UFQPN28 package, can I install a 3.68MHZ crystal, will it work or only in a UFQPN48 package

Can't enter into the debug mode on the development branch, but when I switch to master branch I can normally use the debugger. Difference between master and dev branch is minimal, and projects settings and debugging configuration is the same. I've tried to restart the CubeIDE, clean the project and remove all live expressions, restart the PC, but nothing seems to fix it.

Hello,Is it possible to use bigger pressed button image than released button image? How can I achieve it?

Hi everyone,Something weird happened while I was uploading to my board. The upload crashed half way through and now the USB STLink interface isn't recognized. I think I should be able to upload a working ELF file in UART mode, but to do that I need to boot into bootloader. The user manual indicates that BOOT0 is tied to GPIO B12 (PB12), but I can't find that on the board anywhere. There is a solder bridge for the purpose as well, but I would much rather just use the GPIO. Does anyone have experience with this board who can tell me which pin I need to bridge to get into bootloader mode?

Hello,I am currently using STM32WLE5CC MCU, which has a great feature of RTC with 32-bit sub-second wakeup counter, But I need a low cost MCU for my other non lorawan project, which also need this "RTC with 32-bit sub-second wakeup counter" feature.Please suggest MCU in Ultra low Power with RTC with 32-bit sub-second wakeup counter, and if this sub-second counter underflows, then it generates interrupt.Thank You

Hello,I have a X-NUCLEO-IHM07M1 suite. When I used this hardware and the FOC algorithm(PWM frequency is 8kHz) to drive a BLDC motor. Then I found that the overcurrent protection was always triggered, but I didn't know why it was triggered and how to solve it. Can someone help me?In my control algorithm I am using only the next pins of L6230 chip:- EN1, EN2 and EN3 (for enable the whole bridge),- IN1, IN2, and IN3 (on that pins I generate PWM signals, without dead time),- 3 pins for reading currentsAlthough the motor can rotate, it has the strong vibration and the l6230 chip is seriously hot, as the same in this problem community.st.com/s/feed/0D50X0000AeXo70SQCI use 24V DC input. Here are three oscilloscope waveforms.In the first figure, yellow waveform is a PWM input of the l6230, and the blue waveform is the out1 output, It is obvious that the out1 output is discontinuous.The second is a magnified version of the first picture.The third figure shows that the yellow waveform is the wav

I inherited a lot of NOS chips and would really like to know what these are. A datasheet would be perfect, but every other information about them is welcome.

Hi i want to access remotely my stm32mp157c-dk2 with graphical interface. I am running openstlinux-20-02-19 from starter package. I installed tigervnc (apt-get install tigervnc and apt-get install xauth) and start it by typing "vncserver". But when i connect to it (from vncviewer) only terminal shows up, nothing else. I tried to start some desktop session from this terminal by typing (weston / weston-start / dbus-launch weston-start / weston-launch) but nothing works. I also tried to modify ~/.vnc/xstartup and changed to :#!/bin/shunset SESSION_MANAGERunset DBUS_SESSION_BUS_ADDRESSexec dbus-launch weston-startBut after this change, only black screen shows up : /I am new to wayland/weston and vnc configuration. I hope somebody with more experience can help me with this.

Hello,I used the default .IOC configuration by TouchGFX. My intention is to add ETH to the project that was automatically generated by TouchGFX. PA0 was mapped to: VSYNC_FREQ by the default TouchGFX configuration in the IOC. This signal is used for performance monitoring, removing it is ok!Combining ETH/RMII and QSPI is different:I look at the IO’s and OCSPI1 are connected to PD & PG6 (via AF10 for port G)  GPIO’s on the schematic, RMII is connected to PA, PB, PC and PG13 (via AF11 for port G). ( DS13312 Rev 3 datasheet P110) Is it correct to conclude that the IO layout of the board does not allow me to combine QSPI via OCSPI1 and Ethernet communication as both have other requirements for GPIO port G alternate function selection?  Best Regards,Johi.

Hi,I use STM32H7+LWIP+FreeRTOS. With using STM32IDE and this forum I can now ping to my board from PC and get answer - perfect.Now I want to send and recieve some UDP packets - I can browse the code and try to understand how it all works (how to TX/RX). E.g. Is there any callback UDP_Packet_Recieved(..).. ?But is there any documentation for this combo of LWIP + STM32 + FreeRTOS? Or example how to send or recieve data? Thank you.

HiDo we need to calibrate every sensor in the production line, or we just need to make the calibration once to the standard product?Sensor: VL53L1X.Thanks

Hello Community,I want to connect my STM32U5 ( B-U585IOT02A ) using mqtt to local broker which is running on ubuntu system.I found one example running mqtt in STM32U5 ( B-U585IOT02A ). STM32CubeU5/Projects/B-U585I-IOT02A/Applications/NetXDuo/Nx_MQTT_Client at main · STMicroelectronics/STM32CubeU5 · GitHubBut this example demonstration runs mqtt with tls and test broker test.mosquitto.com But in my case I just want to share sensors data using mqtt to mqtt broker running in ubuntu system over same wifi network.Can Anyone can tell me where should I do changes in the example to achieve connection to local broker.Thanks in advance for you valuable answer.

Hello, I am going crazy, I always get the error that the structure Lcd_Ctx is not declared, while it is clearly declared (by including "stm32h750b_discovery_lcd.h"). With F3 I can find the structure declaration.If I change the file from .c to .cpp the error is gone...See screenshot below: 

Hi. When debugging stm32l476rgt6 on NUCLEO-64 __WFI instruction has no effect.My question is simple: is it possible to enter stop mode while debugging? I know that it is possible to stop dbg clock during clear DBG_STOP bit. But after awake debugger detach from MCU. So, how can I enter stop mode while debugging? Maybe there is some specific configuration of clock?

I'm trying to make my custom STM32WB55 board.Recently, I succeed to start programming the STM32WB55VGY6TR but the advertisement of custom Bluetooth low energy does not start. I tested programming the Nucleo-WB55 board with the same coding and it was successfully coded and advertised custom Bluetooth. So, I can conclude that there is no problem with the code.I checked what is happening in the microcontroller using USART communication, but there is no wireless firmware version (It was 1.0.0 in the Nucleo-WB55 board) and no message regarding starting advertisements like below.  Is there any possible reason it does not work?My RF structure in the custom board looks like below.
