Hi, I am wondering if you can get STM32 MCU with integrated Bluetooth Classic as the only examples I have found (Like WB55) are all bluetooth low energy? 

I followed this tutorial and I'm able to transmit UDP packets from my nucleo board to my computer. I've configured the code to use lwIP without freeRTOS. I'm trying to receive packets on my board over Ethernet by setting up a callback and it never enters the callback even though wireshark shows that packets are being sent. I'm also able to ping the ip address of the nucleo board and get a response. Any thoughts/debugging tips would be helpful! struct udp_pcb* my_udp = udp_new(); udp_connect(my_udp, &PC_IPADDR, 9000); printf("Connected to Ethernet.\n\r"); udp_recv(my_udp, UDP_RXCallback, NULL);void UDP_RXCallback(void *arg, struct udp_pcb *upcb, struct pbuf *p, const ip_addr_t *addr, u16_t port) { printf("in callback\n\r"); /* Free receive pbuf */ pbuf_free(p); }  

 How to debug or run both cores (Cortex-M4 and Cortex-M7) simultaneously on an STM32H747I board using STM32CubeIDE? What are the specific steps and configurations needed to initiate and synchronize the debug sessions of both cores?

Dear all,I'm struggeling to get FDCAN2 working on my board. I also use FDCAN1 - which is working pretty good.For FDCAN1 I selected the RxFifo0 and for FDCAN2 I selected RxFifo1.But for some reasons, I dont get the callback for HAL_FDCAN_RxFifo1Callback().Thats part of my own code, where I used the _weak function HAL_FDCAN_RxFifo1Callback(  // CAN 2 receive interrupt callback void HAL_FDCAN_RxFifo1Callback(FDCAN_HandleTypeDef *hfdcan, uint32_t RxFifo1ITs) { //.... // the incoming message will be used for further scenarios //... } I can also see that the interrupt function will not be called for FDCAN2 if I put a breakpoint into this section (FDCAN1 is working as mentioned) void FDCAN2_IT1_IRQHandler(void) { /* USER CODE BEGIN FDCAN2_IT1_IRQn 0 */ /* USER CODE END FDCAN2_IT1_IRQn 0 */ HAL_FDCAN_IRQHandler(&hfdcan2); /* USER CODE BEGIN FDCAN2_IT1_IRQn 1 */ /* USER CODE END FDCAN2_IT1_IRQn 1 */ } I also added my .ioc file - much appreciate

As per JimSChen.4 said in the year of 2020, "This question has been asked several times but I have to raise it again". I am stuck on this EXACTLY same issue again.Board: STM32H757-EVALSTM32CubeIDE: Version 1.15.1 (Build: 21094_20240412_1041(UTC))STM32CubeMX version (6.11.1)STM32Cube FW_H7 V1.11.2Configuration:System Core->CORTEX_M7: both CPU DCache and ICache are enabledConnectivity->ETH->Mode: RMIIFREERTOS_M7: CMSIS_V2Now the issue is exactly as JimSchen said in this link "STM32CubeMx NO_SYS/With_RTOS option problem with lwip and FREERTOS" 1. LWIP's "Enable" greys out if only Cortex-M7 is selected.2. When both Cortex-M7 and Cortex-M4 are selected, "Enable" becomes available. However, NO_SYS (OS Awareness) is always "OS Not Used" and unchangeable.By the way, an old project, created by using STM32CubeMX version (6.8.1) and STM32Cube FW_H7 V1.11.0, does not have this issue. I can still enable LWIP with only Cortex_M7 selected. However, if migrate to the lates

I decided to replace the STM32F105 with the STM32G0B in my project.I have problems setting up FDcan.The STM32F105 had an “automatic bus-off management” setting, but the STM32G0B does not! This feature is enabled by default, how can I disable it? So that when Can-bus has errors, it doesn’t stop!

hello,I have a very simple question, I have asked a FAE,but not solved.I am using STM32CubeMX to config a project. I used an external 32.768khz crystal. I want to set the RTC clock to the external crystal. below is my setting.I think i have enabled HSE and LSE. the clock to RTC is fixed to LSI RC, but I want to use LSE, not LSI, how can I setting? Thanks,dqsh06

Hi st friends:  stm32mp135f-dk bord use pmic  STPMIC1D, but it is too expensive than STPMIC1A.can i replace STPMIC1D with STPMIC1A

I am using LSM6DSOX with Unico Gui, how can i plot external data in Unico Gui? Is that possible? The data is in the attachement

Hello, I have never used STM before and I am trying to choose a product, but I cannot buy and try each of them due to their prices. I am doing high-frequency work and I need a screen. STM32H735G-DK is a suitable board for me. However, there is a question that comes to my mind: When I select the board with STMCubeIDE, an exclamation mark appears next to the ADC pins on the board and I perceive the usage as restricted. In my application, what I need to do is to determine the time difference between the points above the threshold value among the data coming from an ADC pin. I also want to display the incoming data as a graph. Can I realize the application I want to do using the STM32H735G-DK board? Thanks.

In the ethernetif.c file,typedef enum{RX_ALLOC_OK = 0x00,RX_ALLOC_ERROR = 0x01} RxAllocStatusTypeDef; // Here, RxAllocStatusTypeDef type is not used.It says that RxAllocStatusTypeDef is not used, which violates misra-c:2012 2.3.Inferentially, this would require changing the type in the following code:[before]static uint8_t RxAllocStatus;[after]static RxAllocStatusTypeDef RxAllocStatus;It looks like the code should be changed, what do you think?

Why the uart stops working on stm32h755 device once the core clock has been modified and code has been generated using cubemx. It comes with a BSP code for serial communication (which i tried seperately) , that is also not working once the core clock has been modified.by defualt the core clock is in 64Mhz, if i switch the core to HSI with core running at 400Mhz the uart is giving garabage on the terminal in a fresh project. This is the initilization function generated by cubemxvoid MX_USART3_UART_Init(void){/* USER CODE BEGIN USART3_Init 0 *//* USER CODE END USART3_Init 0 *//* USER CODE BEGIN USART3_Init 1 *//* USER CODE END USART3_Init 1 */ huart3.Instance = USART3; huart3.Init.BaudRate = 115200; huart3.Init.WordLength = UART_WORDLENGTH_8B; huart3.Init.StopBits = UART_STOPBITS_1; huart3.Init.Parity = UART_PARITY_NONE; huart3.Init.Mode = UART_MODE_TX_RX; huart3.Init.HwFlowCtl = UART_HWCONTROL_NONE; huart3.Init.OverSampling = UART_OVERSAMPLING_16; huart3.Init.OneBitSampling = UART_

Hi,I'm developing a GUI invoking STM32TrustedPackageCreator_CLI tool to generate SFI encryption key file and nonce file, but I have no idea on the command syntax, does any one can help me? thanksLuke 

Hello all, I have to develop an application with a 7 inch screen driver SSD1963,for the choice of cpu. I'm deciding between an STM32H7B3 and STM32F7xx, on the card I need RAM for screen storage,touchscreen management, communication with an FPGA in SPI and good fluidity when changing screens. Do you have any advice for choosing the CPU?Best regards, Sébastien

Hi Team, We purchased the LIS2DW12TR MEMS sensor and we found there is a QR code + T marking on the body of the IC. In the datasheet, there is no mention of body marking. Please confirm that this is the correct part we purchased.Thanks,Abishek

I am using the latest OpenSTLinx (5.1.0) Linux version: 6.1.28, and it can display normally when using the official root file system (st-image-eston-openstrinux-eston-stm32mp1. ext4), as shown in the figure below. However, when I use the root file system generated by buildroot myself, it cannot display normally, and there is no output on the screen when using "echo test_ceool>/dev/tty1". Some example screens running qt5 also have no output. Is there anything to pay attention to when building a root file system using buildroot?

Hi,I recently bought an STM32H747I-DISCO board and I'm trying to run the JPEG_MJPEG_VideoDecoding code example with an external display. The code works fine with the on-board display, but I'm struggling to get it working with an external display that uses a GC9A01 driver.I'm confident the issue isn't with the new display or its associated code because I've successfully tested it with static JPEG decoding (not MJPEG). I suspect the problem lies within the code example I'm trying to modify, specifically in the DMA2D section. It appears that the external DRAM is not written to during the final phase of the decoding by the DMA2D peripheral. As a result, when I run my lcd_draw() function, it shows garbage on the display.My modifications to the original code involved disabling all on-board LCD functions and replacing them with my own LCD functions.Can you help me understand why it doesn't work?It follows the part of code I modified and an image. Here is the main code I modified; in

I have a WBC2TX50 eval board along with a STEVAL-WLC98RX for testing Qi powe transfer. When I try to make the transfer, the WBC2TX50 board does not go past FSM_PRE_PING_STATE, either with the WLC98RX or with a phone, both of which work with a standard Qi transmitter.The circuit does respond to the coil (MeasQfactor is 156 free, around 76 with the WLC98RX coil and less than 20 with foreign object). Why is the TX50 board not going past this stage? Do I need to configure something past the default settings for it? Please advise, thank you in advance.

I'm using an STM32 H7 and CubeIDE, As the title states, When placing a breakpoint at HAL_UART_TxHalfCpltCallback, it is triggered.But when placing it at HAL_UART_TxCpltCallback it is never triggered, it used to work, but I don't know where it went wrong. Is there a setting for this in Cube IDE? I don't use the halfcplt function, but it was now just added to search for the error.I'm using normal DMA at highest priority. (I'm running multiple uart's and SAI with DMA) void sendGPSdata(){ if(1){//gps_out[gpsoutpointer-gps_data_size+15] =='A'){ uart_tx_state = 1; set_header(gps_data_size,gps); set_payload(gps); set_footer(gps); HAL_UART_Transmit_DMA(&huart4,&uart_out[0],GPS_packet_size); } gps_data_behind--; } void HAL_UART_TxHalfCpltCallback(UART_HandleTypeDef *uart){ if(uart == &huart4){ //4g } } void HAL_UART_TxCpltCallback(UART_HandleTypeDef *uart){ if(uart == &huart4){ //4g uart_tx_state = 0; if(audio_to_uart_data_behi

Hi guys.I am using the guide below for starting communication between two MCU. Getting started with I2C - stm32mcuThe code is simple, but it did not work.Master code:I checked the SDA and SCL with different transferred data Txdata and Txdata2.But two consecutive pulses series are totally same. There is any idea about this problem.Thank you.Of course, I also cannot receive data at slave MCU too.

Hi,I write my own 'void HAL_SPI_TxRxCpltCallback(SPI_HandleTypeDef *hspi)', intend to override the default weak one. But when debug, my version is never called, it always steps into the 'weak' one. I'm new to CubeIDE, the version is 1.16.0, any suggestions?Thanks.

There is a note for UFQFPN32 package, that says "There is an exposed die pad on the underside of the UFQFPN package.", But there is no similar statement for UFQFPN28 package for the same device. Is it intentional or missed or if there is any plan to add if it is intentional?

Hi,      My one microsecond timer configured by CubeMx running on NUCLEO-C031C6 (STM32C031C6) is 3 times slower than it should be.
