I’m using the STM32H750B-DK board to explore FD CAN integration with TouchGFX.  I currently have the FD CAN working but I can't get the touchgfx to work properly.  Is there anyway to merge a touchgfx project with a STM32H750B-DK stm32cubeide?  To clarify, I want to merge a existing stm32cubeide project with a new touchgfx file.

Hi, in my project I am try to jump 0x8002000 address . but I am facing some failure, typedef void (*FunctionPointer)(void); // Example function to jump to another addressvoid jumpToAddress(uint32_t * address) { //address =0x800029c;    // Define a function pointer with the address    FunctionPointer jumpFunction = (FunctionPointer)address;    //void (*jumpFunction)(void) = (void (*)(void))address;     // Disable interrupts if needed       __disable_irq();        // Set the program counter (PC) to the new address       SCB->VTOR = address;        // Execute an instruction to ensure that the jump takes effect       __DSB();       __ISB();        // Re-enable interrupts if needed       __enable_irq();     // Call the function via the f

I noticed that areas of internal SRAM appear to be used by GFX. I inferred this from a project I am doing with an H745 dual core micro; I set aside a small amount of SRAM4 to be shared between the cores, and I can watch on the debugger as portions of that memory space can be updated or not, depending on whether I have interacted with the LCD. This suggests that GFX is helping itself to the SRAM, and I need to know how we can declare an amount of internal RAM off-limits (or, are there documented regions of SRAM that are safe to use when running GFX?). The DISCO board uses external SDRAM, by the way.  Thanks for any insights someone might be able to offer.

I have installed Version 1.11.0 from STM32CubeIDE and have to install an older toolchain for my stm32H7 project. But Toolchain Manager throws the error "Failed to fetch the toolchain list, please check your network settings."In the thread behind this link Employee Julien D say that this is a known error, but in my case I'm not able to choose a new toolchain. Is there a workaround for this problem?

Hello,I have an STM32H750B-DK board which includes two quad SPI flash chips (MT25QL512ABB8ESF-0SIT x 2).When I use STM32CubeProgrammer to write or erase the external flash, the erase operation can only be done in 128KB units.I thought the sector size of the flash was 64KB.Why does STM32CubeProgrammer show the flash size as 128KB?Thank you for your help.  

Hello!I'm trying to make a open source test board which allows people with an Arduino to try out using the STDrive101 chip. However, I'm running into an issue where it appears to be entering fault mode and refusing to leave it (leaving all mosfets disabled and making the board more or less a brick). I've attached the schematic (and here's the repo with the Kicad project and arduino code https://gitlab.com/charlesrwest/stdrive101testboard ) but I've also put a brief rundown on the setup below:Operating voltage: 12.3 volts2 massive 1000uF capacitors to keep source voltage steadyCP set to ground to disable overcurrent shutdown (so CP never higher than Vref)DT/Mode connected to ground with a 200kOhm resistor (should result in dead time of ~2000 ns).SCREF left floating to disable Vds monitoring protectionVS has a 100nf bypass capREG12 has a 22uF cap and a .22uF cap (seem reasonable?)NFault left floating, but adding a pullup resistor doesn't seem to change anything (it pulls down)I

Hi,I just downloaded "STM32L496.svd" (Version 1.3) from ST homepage and noticed that there are missing bits in register definitions:CCMR1:Bit 16 -  OC1M[3]Bit 24 - OC2M[3]CCMR2:Bit 16 -  OC3M[3]Bit 24 - OC4M[3] 

I spent many hours trying to make the SPI3 works through the use of the HAL but it was doing weird things (not clearing IRQ flag so ISR was continuously called).Then I found that SPI3 is limited to a size of 1023.I also found on this forum other people having the same problem with SPI3, so I think some improvement can be done:- It would be great to have HAL function return an error when called with a too big size.- On STM32CubeIDE SFRs, SPI3.SPI_CR2 should have a TSIZE[0:10] instead of [0:16]- In RM0456 Rev 5 page 2924, I think "TSIZE cannot be set to 0xFFFF respective 0x3FFF value when CRC is enabled." is wrong (0x3FFF instead of 0x3FF, respective of what ?). I think something like this would be better "TSIZE cannot be set to 0xFFFF (0x3FF for limited feature) value when CRC is enabled.".

I have an STEVAL-MKI109V3 and the MKI238AA evaluation boards.I was unable to communicate with the MKI238AA with the UNICO-GUI software so I updated the firmware on the MKI109 with the ProfiMEMSToolV3.60.7 .bin file using the STM32CubeProgrammer following the instructions in the video below.ProfiMEMS Firmware Update using STM32 Cube Programmer (youtube.com) The MKI109 LEDs now do not switch on when the board is powered via USB and the device is no longer detected in the Device Manager.The blue LED still switches on when I place the device into DFU mode but I am unable to interact with the device outside of this mode.I am running Windows 10.What can I do to resolve this?

 Hello ST experts,I am a beginner with the STM32WL series and need some support.So first I started with the STM32F407VG disc1 and I tried to communicate two boards of it using a SI4432 module and I didn't succeed, I tried something else and I bought two Nucleo-32WL55JC1 boards and tried to communicate them and it works as shown in the last post.It works as a ping pong application -you can find a better description about this application in this link page 44- after that I tried by developing the same code of the ping pong application to communicate a nucleo-32wl55jc1 with nucleo-32wl55jc2 because in the datasheet they don't use the same frequency but it works!Now I am working on RF communication between nucleo-32wl55jc2 and another RF device like a key car or a key garage with the same developed code of the PING PONG application but still I don't have any answer.My first question is if the NUCLEO-WL55JC cards are able to read RF signals from these RF devices?The second one is if th

As written in the title, the ST25PC-NFC software does not detect the STEVAL-25R3916BA reader, despite being in the list of compatible readers. What can I do?Thank you

I'm currently testing Tracealyzer but I'm having problems in using it in streaming mode. I followed the indications in video "Visual trace diagnostics with STLINK-V3, Percepio Tracealyzer and DevAlert" (https://www.youtube.com/watch?v=rZlSuq7TySA) to setup ITM but it seems not to be working. SWV is enabled, clock is set as on target, "Shared ST_LINK" flag seems to have no effect, ITM Stimuls Port is set correclty.- Tracealyzer 4.8- STM32CubeIDE 1.15.1- ST-Link V3 or ST-Link V3 Mini (same result)- No RTOS (bare metal)- Custom boardOnce the system is set up according to the video, if I start debugging from STM32CubeIDE, starting tracing from Tracealyzer gives the error "Unable to select and reset device" (in the Tracealyzer setting window the ST-LinkID is recognized correclty). The SWV Trace Log window in STM32CubeIDE shows the activity.If I start the trace from Tracealyzer I can't start debugging from STM32CubeIDE as it stops at the ST-Link firmware verification with the error "No

I have created a custom container which includes some text boxes, scrollists labels etc to allow the user to set the parameters for an alarm. I add one of these custom containers to my listlayout in code for each alarm to be set. So the user is presented with a list of alarms, and the opportunity to change the settings for each alarm. I have also created a modalwindow containing a keyboard. The desire is when the user clicks the box for an individual alarm to set the numeric value of the alarm limit, a modalwindow pops up, so the user can enter the new numeric value, which is saved into the model value and displayed in the relevant box in the list for this alarm, when he clicks save in the modal window and closes it.The problem I have is that when the boxclickhandler displays the modalwindow, it only displays the tiny portion of the modal window which covers the listlayout, rather than popping up the modalwindow over the entire screen:I guess this is because the modalwindow is a member

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 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
