Solved

I am using USB peripheral on the STM32U5 with TrustZone enabled. I met a problem. In Non-Secure area, USB_DRD_FS->CNTR, USB_DRD_FS->CHEP0R can be set correctly. In Secure area, I can set "USB_DRD_FS->CNTR = 0x9D00;".But I can not set the "USB_DRD_FS->CHEP0R = 0x8280;". The register value remains at 0. How can I use the USB peripheral in Secure area?

Hi all!Thanks again for the help so far.Just another question, is it possible (or normal?) when creating a pack to have it insert snippets of code into main.c just like the code snippets that get inserted by the cube when you change peripherals etc? Thanks again. 

Hello, is there any documentation regarding the startup on both cores as I see there are several possibilitiess to gate the other core or to let them run directly in parallel. Nevertheless, CubeMx generates a common startup file which is shared I assume. Does ST provide more information on this topic? Where can I find some reference material, e.g. ARM for a dual core approach?

I want to change the screens above into slides. I want to know how to slide between screens without swipe container. Please help me.

I can find the UM1021 document for STM32F105xx, STM32F107xx, STM32F2xx and STM32F4xx, but nothing for STM32F7xx.Any help would be appreciated.Thanks

Hi,in ds for STM32H747xI/G  , DS12930 Rev 2 , for Temp.sensor CAL2 : 130° (Parameter) is written here: BUT  max. temp for chip is 125° :So i assume, this is misspelled  , because in all other : (H743, H750, H7A3 ..) 110° + 30° are given.NOT 130° .   

I just finish a TouchGFX code to generate an adjustable sine wave. I am planning to make 3 of them to mix them and play chords but there is a problem: how can i play a function that generated in STM32 on the speakers of that STM32?I would be so glad to any help from you all.

Hi,  i am using STM32H753z  i try to switching FDCAN GPIO is PD0, PD1  to UART tx and rx (same pins)now i changed FDCAN to UART tx side  is fine but in Rx side  i face issue ( no data is receiving to receive buffer).     #define CAN_AFR 0x99 #define UART_AFR 0x88 #define CHANGING_PORT 0xFFFFFFFA void switch_UART_TO_CAN(void) { if(HAL_UART_DeInit(&huart4) != HAL_OK) { Error_Handler(); } GPIOD->AFR[0] = CAN_AFR; GPIOD->MODER=CHANGING_PORT; MX_FDCAN1_Init(&hfdcan1); } void switch_CAN_TO_UART(void) { if(HAL_FDCAN_DeInit(&hfdcan1)!= HAL_OK) { Error_Handler(); } GPIOD->MODER=CHANGING_PORT; GPIOD->AFR[0] = UART_AFR; HAL_UART_Init(&huart4); MX_UART4_Init(); }      

My use case is about computer vision (yolo model preferably) and how to monitor its inference in order to have an idea of its carbon footprint when running on the chip. I heard that stm32-zoo has a yolo model available, so it is possible to use it on the chip (correct me if I am wrong :D).Would you have any useful tips for such a case regarding the monitoring part? Is there a dedicated software available from ST?Thanks in advance ST Community!

Hi    i am receive data using UART 4 and transfer same data back like loopback but data is mismatch.  same process in stm32f207 is working,    #include "main.h" UART_HandleTypeDef huart4; void SystemClock_Config(void); static void MX_GPIO_Init(void); static void MX_UART4_Init(void); int main(void) { char rx_buffer[10]={0}; HAL_Init(); SystemClock_Config(); MX_GPIO_Init(); MX_UART4_Init(); while (1) { HAL_UART_Receive(&huart4, rx_buffer, 10, 1000); HAL_Delay(100); HAL_UART_Transmit(&huart4, rx_buffer, 10, 100); // HAL_Delay(1000); } /* USER CODE END 3 */ } void SystemClock_Config(void) { RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0}; /** Supply configuration update enable */ HAL_PWREx_ConfigSupply(PWR_LDO_SUPPLY); /** Configure the main internal regulator output voltage */ __HAL_PWR_VOLTAGESCALING_CONFIG(PWR_REGULATOR_VOLTAGE_SCALE2); while(!__HAL_PWR_GET_FLAG(PWR_FLAG_VOSRD

Dear community, on the ADC3 IN18 (internal temperature), I have an unconsistancy between the output of the ADC (reflecting the value of the temperature and the reference value TS_CAL1 and TS_CAL2 (0x3114 and 0x40C0).the ADC is in 16 bits and I got a value from the ADC 0xA152.When using the formulae converting the value from ADC to temperature, the result give 685 °C !!!!I change the conversion scale to 12 bit, and now the result is -163°C.it seems the reference value are fix whatever the ADC scale range. but nowhere I found a formulae explaining the influence of the conversion scale neither the influence of Vref.we extend the sampling time to comply with the minimum 9 µs.  

We are planning to make a board using a STM32 MCU in a Modbus application. What we need is a Modbus-RTU. We found that STM32F030 can satisfy our needs and cheap enough but it does not support Modbus. Could we use STM32F030 in this case by special software additional design or we should find another MCU supporting Modbus? If we could use it then we need support about the additional software design. Would you please support us?Thank you!

I am programming USB DFU in stm32f407g disc1 but i am not able to connect it in stm32cubeprogrammer as it is showing usb port as usb1. Can anyone tell me is it anything missing?

I am trying to interface CAN communication in loopback mode in STM32F469I DISCO but it is not working.

Good morning, I'm looking for the sources of the USB communication library for the CR95HF DLL, unfortunately the downloadable library is only for 32 bit systems, I would need the sources to be able to compile it at 64bit and eliminate the problem.Can anyone help me solve my problem?

[VERSION]: MCSDK 6.2.1, 6.3.0 (CubeMX 6.11.0, STM32G4 FW V1.5.1)[TOOL]: Motor control WorkBench[DETAILS]: When creating a project that has the Hall sensor of a motor selected as the main sensor and also the Open Loop debug feature enabled, the resulting project can't be built due to missing defines and variables.[EXPECTED BEHAVIOR]: I expect the tool to create buildable and working code.[HOW TO REPRODUCE]: Create a configuration like mentioned under DETAILS. I renamed and attached a MCWB configuration made with preset hardware (I-PMSM 24V motor, B-G431B-ESC1 inverter).Generate code from project.When importing the project in CubeIDE and trying to build it, following Errors pop up:- undeclared defines OPEN_LOOP_VOLTAGE_d, OPEN_LOOP_VF, OPEN_LOOP_OFF, OPEN_LOOP_K for the OpenLoop_ParamsM1 typedef in mc_config.c- 'VirtualSpeedSensorM1' undeclared, used in various places in mc_tasks.c

Hi all.Please tell me, for example, CubeIDE has environment variables and I can create my own by setting their values ​​through CubeIDE itself and passing them to the target assembly, but can I somehow change the value of my environment variable using additional scripts?Here's the situation. I create an environment variable and bring it to the assembly definition. I also create a .bat script where I import it and change it, and add the script call to PREBUILD, but unfortunately, when assembling the project, I see that the change has not been changed. Is it actually possible to implement the scenario I described in CubeIDE?Yes, I understand that I can use make/cmake directly or create a separate .h file. My scenario is more of a sporting interest.I will be very glad to help and advice

Please help me to fix the next warning messageaopears when i opened the ST25R3911B discovery gui 

I'm used to using the stm32cube-ide. I found a Nucleo-MB1549 in my attic and wanted to play around with it but i can't seem to find it in the board selector section.  Any ideas what i should do next? This is a genuine nucleo board and i am able to find my other nucelo board using the application

Hi, I have a question.I am developing a BLE HIID device using the STM32WB55 evaluation board.I am not sure how to identify multiple devices with the same firmware loaded.The problem I am currently encountering is as follows ↓↓↓.Prepare two CFG_STATIC_RANDOM_ADDRESS and switch between them on each evaluation board.Two devices appear on the advice screen (windows pairing screen)If one is connected, the other cannot be connected.I would appreciate it if you could tell me the cause of this phenomenon described above! Thank you in advance.

Hello,I am working on a project to design an IO and motion controller board using STM32H755 mcu. Could you please review the attached basic schematic design for the mcu to avoid any design related issues that may arise later. +3.3V power is coming from a switching regulator. Is it necessary to put small value resistors at the TX and RX of UART pins (H3)? Thank you.

As title says.If so, where could I find an example.If not, will it be supported?
