Dear STMicroelectronics Support Team,I hope this message finds you well.I am currently working with an STM32WB series microcontroller and using STM32CubeMX (version [insert version number]) for configuration.While setting up the project, I noticed that the STM32_WPAN middleware component is grayed out and cannot be selected or enabled.I have verified that the correct MCU/board is chosen and that the project is properly configured for wireless features. However, the WPAN stack remains unavailable in the MX configuration interface.Details:MCU/Board: STM32WB5MMGHx STM32CubeMX Version: 6.15.0STM32Cube Firmware Package:  v1.23.0IPCC : ActivatedHSEM : ActivatedRCC : HSE + LSERF : Activate RFObserved behavior: “STM32_WPAN” option is grayed out and cannot be selected.Expected behavior: The STM32_WPAN middleware should be selectable to configure wireless stack features.Could you please advise what might cause this and how I can enable or access the WPAN middleware in CubeMX?Thank

Hi, I have been using NemaGFX on STM32U5G9J-DK2 kit with no problems however my luck with the STM32H7S78-DK kit is different.1. The NemaGFX for this platform only seems to work with 32-bit framebuffers, not 24-bit ones. Or am I doing something wrong?2. The NemaGFX for this platform uses the beginning of the framebuffer as a sort of workspace. We see random dots at the beginning. I think I'm having trouble allocating buffers correctly.3. I can draw filled rectangles, but filled circles with 'nema_vg_draw_circle()' only show the edge slightly and produce small images in a sort of workspace at the beginning of the frame buffer.nema_vg_set_fill_rule(NEMA_VG_FILL_NON_ZERO); does not fill the shape, as it should.Well, 'nema_vg_draw_rect()' works fine with nema_vg_set_fill_rule(NEMA_VG_FILL_NON_ZERO).4. Many more graphics functions don't work properly on the STM32H7S78, but they all work fine on the STM32U5G9J, which one uses 24-bit framebuffers, while the STM32H7S78 can o

Please i need help. The datasheet, says the VDDA voltage level must be always greater or equal to the VDD voltage leveland must be provided first. My qustion is: will my circuit work, if I tie the VDDA and VDD together, to be powered by the same  LDO DC-DC converter?   Thanks in advance.

I could successfully operate the X- NUCLEO IKS4A1 in the MEMS Studio with the default sensor selection on the board. However, when I tried to select the LSM6DSV, which is connected on the DIL24 socket of the  X-NUCLEO IKS4A1 board, for the accelerometer and gyroscope sensor configuration in MEMS Studio, I get the following error window: The WHO AM I register value does not match the device selected I also connect two jumpers between 9-10 for the headers J4 and J5 on the X-NUCLEO IKS4A1 board and removed the two jumpers between 11-12 for the header J4 and J5. Do you have some recommendation, what I miss here?Many thanks in advance. Best regardsChristian

Hi,Looking into STM32CubeN6\Projects\STM32N6570-DK\Examples\SD\SD_ReadWrite_DMA example,I see that quite heavy operations are used:SCB_CleanDCache_by_Addr (aTxBuffer, BUFFER_SIZE); // ...

Hello everyone,I'd first like to mention that this project is being developed with support from ST Brasil, which has provided important components to aid in this development.I'm working on firmware for motor control and, being new to this area, I'm looking for guidance on the best way to implement a specific part of the logic. 1.

Hello Expert, I am working on an STM32F303VET6 project using the MCSDK. I want to configure TIM16 to generate a 10 ms periodic interrupt . However, I noticed that on this MCU, TIM16 shares its NVIC vector with TIM1 (TIM1_UP_TIM16_IRQHandler), which is already used by MCSDK for motor control.Could you please advise:Can I safely use TIM16 for my 10 ms task while TIM1 is used by MCSDK?If yes, what is the recommended way to handle the shared interrupt? Are there any potential conflicts or timing issues I should be aware of?If the solution could be illustrated with an example, it would make me so happy. In MCSDK- 6.41 , #define TIMx_UP_M1_IRQHandler TIM1_UP_TIM16_IRQHandlervoid TIMx_UP_M1_IRQHandler(void){/* USER CODE BEGIN TIMx_UP_M1_IRQn 0 *//* USER CODE END TIMx_UP_M1_IRQn 0 */LL_TIM_ClearFlag_UPDATE(TIM1);R3_2_TIMx_UP_IRQHandler(&PWM_Handle_M1);TSK_DualDriveFIFOUpdate(M1);/* USER CODE BEGIN TIMx_UP_M1_IRQn 1 *//* USER CODE END TIMx_UP_M1_IRQn 1 */}

Dear STM experts:     I am using the STM32G473RET6 chip for classic mode communication debugging in FDCAN, but there is a phenomenon where I cannot send information. In FDCAN-PSR, I can see an error of LEC being 5. After removing the CAN chip (SN65HVD230, R pin floating), an error of LECt being 2 appears. I am preparing to replace it with SN65HVD232,Is there any STM with similar routines to refer to? If so, where can I find it? Thanks. Best regards!

We have a batch of custom boards using the STM32H725IGK3 and have experienced several failures getting started with them as the SWD interface appears to be fried. Initially we thought just bad luck with the first couple (inexperienced engineers or ?) but the most recent unit failed after a few successful programming and debugging sessions. Do these processors need special handling or design considerations ? Our debug header follows previous designs, with Vcc, GND, nRST, SWDIO, SWCLK provided. nRST is gated with a couple other inputs to the MCU while SWDIO and SWCLK just have 100R series resistors to protect possible voltage conflict. So far just default 3v3 supply.When the boards were working, SWDIO showed Vcc while SWCLK showed 0V before any connections (expected based on internal pullups) while now the pins show about 0.8V until the STLINK/V2 is connected (upon which its pullup/downs take over). The STLINK pod has been tested and working on a NUCLEO_H723.It looks like we'll

Testing a board with STM32U5A5. VDD is 3.3VI have configured one GPIO as input with an external pullup to 3.3V through a 470k ohm resistor.The input reads high, but when I measure the input with a scope, I read 2.2V on the input, which is below 0.7VDD which is guaranteed as V_IH, but above 0.5VDD+0.2 which is specified by design as V_IH.Is 470k ohm too high of a pullup resistance?

Hello ST Community teamThe pin F11 on the TFBGA216 figure (figure 4 of the AN4660) should be VDD and not VSS according to the products datasheets (for the STM32F469N and STM32F769Nx6). That should be rectified on the next doc revision. Best Regards.II

Hello, our company is concerned about potential export control restrictions affecting Nexperia products.We currently use several automotive logic devices from Nexperia and would like to know if STMicroelectronics offers equivalent parts as alternatives. Could you please advise?Thanks,Claude.

The STM32CubeG4 package comes with CMSIS v5.6 (https://github.com/STMicroelectronics/STM32CubeG4/tree/master/Drivers/CMSIS) which I think was released in July 2019.Is it necessary to use this version or can I upgrade it to a later release? Currently v6.1 is the latest CMSIS release. 

Hi ST Community,I’m using the STM32MP257F-DK board and successfully followed this guide: Modify, rebuild and reload the firmware Everything worked fine during the initial setup and firmware modification. Now I’m trying to flash a new image to the SD card and connect to the board again, but I’m unable to establish a connection via ST-LINK.

Section 6.1 of AN5056 (for X-CUBE-SBSFU) states that the projects are delivered with the highest level of compiler optimizations turned on for size aspects.If the Optimization Level was set to 'None', then how much larger is the generated code expected to grow for the mapped regions (SE, SBSFU, etc.) excluding the image regions? (% increase in general)Which of the regions will be impacted the most?Update: To aid debug via IAR EWARM, I prefer to develop without any optimizations enabled, understanding that the code output size will be larger. I have no issues if the mappings are allowed to be adjusted to accommodate the larger code outputs.
