Hi,I want to set a common interaction for all buttons on screen. For this, I configured button interactions to call the same virtual function ButtonClicked(). How could I determine in this function, which button was clicked? Is there a way to tell TouchGFX to create a virtual function with a parameter of the clicked button?Thank You

Hello,I wanted to know some suggestion regarding a project, and adding FOTA support in it.The project is stm32f405 based and it configures the gsm module as a server and one can make request and get response using https request.I wanted to update the firmware of the stm32f405 using the gsm module, I have looked into muc like the STM32WB series that have FOTA implemented for Bluetooth, and some basic principle used by the implementation. But I wanted to use the existing stm32f4 mcu and don't want to port my project to stm32wb.Any suggestion(hardware or sotfware) on how can I implement the FOTA.Thankyou.

Hi, I am wondering why STm32CubeMX in some projects will generate the correct order of MX_DMA_Init() before MX_USART6_UART_Init(), but in other projects it will reverse that order. if the order is reversed, then the DMA will not work.I have looked into the *.ioc-files. I notived the Mcu.IPxx fields are not ordered correctly starting with Mcu.IP10.working file (DMA_init before USART6_init)Mcu.Family=STM32H7Mcu.IP0=CORTEX_M7Mcu.IP1=DMAMcu.IP2=NVICMcu.IP3=RCCMcu.IP4=SYSMcu.IP5=USART6Mcu.IPNb=6not working file (DMA_init after USART6_init)Mcu.Family=STM32H7Mcu.IP0=CORTEX_M7Mcu.IP1=DEBUGMcu.IP10=TIM3Mcu.IP11=USART6Mcu.IP2=DMAMcu.IP3=ETHMcu.IP4=FREERTOSMcu.IP5=HRTIMMcu.IP6=LWIPMcu.IP7=NVICMcu.IP8=RCCMcu.IP9=SYSMcu.IPNb=12Is there anything I can do to get generated code that is independent of the Mcu.IPNb < 10 ?

Hi!I am following the instructions of this wiki page:https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP157x-DK2/Let%27s_start/Populate_the_target_and_boot_the_imageI have the DK2 connected to my system using the USB OTG port.The boards dip switches are in the correct position.I copied the udev rules to /etc/udev/rules.d/.Pressing "Connect" results in following error: 16:44:36 : STM32CubeProgrammer API v2.8.0 16:50:03 : USB speed : High Speed (480MBit/s) 16:50:03 : Manuf.

Hi!I don't know really how to explain this. But I have enabled CANBUS and it works very good. I also have activated USB and it works too.But since I have changed the preemption from 0 to 1 for CANBUS RX0, I have no ability to use USB connection.I changed the preemption from 0 to 1 for CANBUS RX0 because else SysTick would stop. HAL_GetTick() gave the same number for ever as long I was inside the CANBUS RX interrupt function.What happen when I have 1 for CANBUS RX0 in priority and plug in the USB. From my computers perspective, it says that it could not connect the device.From my STM32 perspective, I get stuck inside this while loop for ever where wIstr = 41465/** * @brief This function handles PCD Endpoint interrupt request. * @param hpcd PCD handle * @retval HAL status */ static HAL_StatusTypeDef PCD_EP_ISR_Handler(PCD_HandleTypeDef *hpcd) { PCD_EPTypeDef *ep; uint16_t count, wIstr, wEPVal, TxByteNbre; uint8_t epindex;   /* stay in loop while pending interrupts */ while

I have been using USB_FS for some time now and recently added the EXT13 IRQ for the user button in the STM32L5 DK. I set a task to toggle a pin when the button is pressed and noticed that if the USB is running, the event does not wake the user button task. If the USB is disabled or does not start properly, the task wakes and functions as expected. If I remove the event flag wait, the task functions normally. I have tried both IRQ priorities equal and lowering the USB priority with the same result that the task does not wake when the USB is active.

I have a multi target project.My targets are STM32L152CB and STM32L152RC. I use Ubuntu 20.4 with STM32CubeMX 6.3.0.Since STM32CubeMX does not natively support multiple targets I've decided to have two cube projects in the same folder. The generated files are the same since both targets use the same pins and peripherals and have the same core. The only difference is the processor type. Common application code will be in a seperate folder from the generated code and the project files.The first problem I encountered was that you cannot rename the .cproject, .project and .mxproject files. They are nameless and I couldn't find an option in STM32CubeMX to add a name. Therefore they will overwrite the existing files from the other target, so you cannot have both project files in the same folder. My workaround was to place the ioc files in seperate target folders.My second problem is that now each target folder has a copy of all the sources. I want all the sources in one place. The ioc file ha

Hello community,It is possible that an interrupt will be nested over itsef?I mean, I have one interrupt EXTI0_IRQHandler() and inside the interrupt I am waiting an event that requires the execution of the same interrupt. I read the PM0214 and it is said that "Preemption When the processor is executing an exception handler, an exception can preempt the exception handler if its priority is higher than the priority of the exception being handled"In my case, Could I change the prioriry of the IRQ dinamically so the new event will be processed as a new IRQ nested with the same IRQ??Thank you very much for your help

I have an ST25R3916-DISCO board which I am using to communicate with ST25 tags with an antenna. I'm using the ST25R3916 Discovery GUI to see the tag information on the computer. My antenna is being recognized, but how do I read the RSSI value of the signal? I read on multiple forums that they use the rfalGetTransceiveRSSI() command to obtain RSSI values, but how do I send the command? Is there any example code for the same?

i guess it might be the same, but just would like to make sure.thank you very much.

We have a custom board with an STM32F407 on it. I used CubeMX to create the project and enabled HTTPD. I used the example LwIP_HTTP_Server_Netconn to get a webserver running. I have a few pages working including a dynamic page. Next step was to create a page that would allow the user to Submit a file to upload to the webserver. I used the In Application Programming example for the STM324xG_EVAL board to get ideas on how to do this. The big difference is that it does not use netconn... Everything is fine until I press submit on the page, then the following happens:If you submit with no file chosen my code detects this and then does a netconn_write of the same page. Then it closes the connection and deletes the netbuf. When this happens I see from Wireshark that the first packet is sent out to refresh the page but it takes 3 packets and the other two never go out to the browser. I then see keepalive requests and responses from the browser and webserver after this.It gets stuck when you a

Could someone please shed some light on the algorithm the VL53L0X and VL53L1X use to calculate the distance from the returned photons for each laser pulse? @John E KVAM​  you’ve mentioned in other blogs that photons seen are “averaged�? – is the logic something like “during the return period there were X number of photons counted, photon number X/2 was counted in bin #11, therefore use the time of this bin for this pulse�??I’m really interested in this because like a couple of other people have noted I’m finding both these sensors return consistently different distance for surfaces with different reflectance. I’m not using a cover glass, the sensors are perpendicular to the surface, I've been using a 100ms timing budget averaged over 50 ranges and am measuring fairly short distances (between 177-279mm). Some results for different materials arranged from shiniest to least shiny (according to my best judgement) are attached.As you can see the error trend is fairly consistent between

Edit 2: CubeMX 6.2.1 is working aswell. Will use this version for now.Edit 1: CubeMX 6.0.0 and 6.2.0 are workingAfter Code Generation, the 3 injected Channels (0,1,2) would be all initialized with ADC_INJECTED_RANK_1 despite other setting in CubeMX.With older Version this was working. Did something change with the setup which I don't understand or is this a possible bug? 

Hi, I am using B-G431B-ESC1 board for tests and MC-SDK 5.Y.2. I have a motor with Hall sensors. Are there any possibilities for braking the motor other than setting a downward speed ramp to 0.I mean regenerative braking methods, and I'm also wondering if it is possible to keep the motor in place at zero speed despite attempts to turn it. Without using an encoder and position control, namely with Hall sensors and current measurements.Perhaps this is outside the scope of the MC-SDK, but I would still like to know the possible options.

What output data format does the STEVAL-STWINKT01 develepment board use? (.dat) How can I make this data visible and view it? For example, in excel. It would be nice to see what data the device has saved to the SD card and process it. How can this be done?

Hi,Master:MCU: STM32H750VB(LQFP100)Application requirements: Requires LCD controller to drive 7" (1024x600 pixels) TFT screen.Power-on initialization to load image resources from external flash to RAM and LCD buff requires RAM, which requires a lot of RAM, so externally expand SRAM and drive through FMC.Problem: Some FMC pins are the same as the LCD controller, but they cannot be multiplexed and mapped to other pins, causing conflicts. For example, PE14 is the conflicting pin of LCD_CLK and FMC_D11Expectation: Without changing the MCU model, is there a way to resolve this conflict and achieve application requirements?thank you very much!​

Hi,I'm use STM32F103C8T6 for some subsytem of UAV. I want to program my STM32 via USB port but i cant find any document for atollic or cube ide. I find only for arduino IDE. What can i do?Thank you.

Hello, Till now I was using ST25R3911B NFC chip for read/write (ISO15693).Unfortunately ship have long lead time. Can you please advice me which chip to use as alternative to have less changes on the PCB as possible?? (ST25R3912, ST25R3915, ST25R3917,... ??)Thank you,Domen

Hi all,I'm trying to implement a class that should allow me to use the USART with the DMA. It's a learning project in which I'm trying to learn how to retrieve the correct information from the datasheet and the reference manual. I'm reading the reference manual RM0390 and the datasheet STM32F446xC/E.I don't understand how I can choose the correct stream and channel for the USART. take as example the USART1. At page 207 section 9.3.4 there is the table 28 and 29that is telling me what is connected to the streams and channels, but it's written that they are examples.Does it means that there is no fixed configuration and that I have to choose or is it the only usable configuration? If the answer is the first how can I choose?

Hello, all.How to post info about found bugs in STM32CubeMX?Can't find correct way for it. (Feedback? ST Online Support Center?)Thank you.

Hi,I need to change a screen's look at run time. For example, upon command, change background color of screen1 to a specific color. My problem is that after moving to screen2 and then back to screen1 the new background color is lost since TouchGFX calls the base class that uses the original color. Any idea how to keep new setting also after switching between screens? I wouldn't like to change the base code that is generated and not meant to be updated by user.Thank you,Ari

HelloI am new to STM32. I want to Use FOC for controlling sensorless motor. Which MPU/MCU can be used for ESC of drone motor. I found STEVAL-ESC001v1 can be used as reference design for entry level commercial drone design. Which software I need to download and only ordering ESC001v1 will be sufficient to start project? or is there necessity to order other board?
