Is there a way to use the HAL library to read the variable specified in the address?

Hello STM32-community,I'm struggling with the USB-connection via hTerm of my STM32. I'm trying to send a few bytes via USB, receiving them with the tool hTerm, but it cannot even connect to the Microcontroller. Terminal20141030 works just fine, while LABView also struggles.I've tried many different things and applications, changed the USB, uninstalled and reinstalled it, tried different microcontroller which all worked fine, made sure that the USB-Port is not occupied by any other tool [...]. Used blank programs who only sent several characters, but it still fails to connect at all via hTerm and LabVIEW, but works with Terminal20141030. Did also some tweaks in the USB.c -

Hi,it seems that the current STM32F4 HAL manual (UM1725, rev.6) is incomplete regarding the U(S)ART drivers, especially for the extension drivers: according to the source code (FW 1.26), there are UART extensions for receiving with idle line detection (which is what I was looking for :beaming_face_with_smiling_eyes: ), but those extension functions aren't mentioned in the user manual.I assume that the functions work and the documentation simply doesn't mention them.

Hey,I'm programming with the STM32F415 MCU and discovered that the FLASH_CR_ERRIE declaration is missing in the CMSIS files. Is this a known issue or even intended?If it is not intended, I assume I can safely add the missing declaration? (I never had to touch them, so I'm careful about that.)If there is a reason why it's missing, could someone please point that out to me?Thank you in advance and best regards,Moritz

In another project I have used USB with HAL library in same MCU (STM32F429) without RTOS and it worked, now I am having problem in read and write USB with FREERTOS. Can you suggest any project example for the same?

I am working with demo board STM32G474E-EVAL and try to run example project in which board works in Source mode.When I connect the power bank (HyperJuice Power Bank 130W USB-C) to the USB-C, the board starts constantly sending messages about its capabilities. In this case, the power bank does not answer anything and charging does not start.The power bank works properly with other chargers and it can work in Source and Sink modes using various power profiles.Can you explain what is happening and how I can start the Source mode so that the board starts charging the power bank.

Hi there,(I'm posting this mainly not as a question, because I know the answer, but as an answer for other people to find, because I spent quite a long time trying to figure this out.)I've recently started with a project that uses the Nucleo-L552ZE-Q board. I've done some things with microcontrollers previously, but nothing with the STM32 until now.I downloaded STM32CubeIDE, created a new project for that board, said yes when it asked to add all of the default peripherals for that board, and added the USB FS device middleware (which specific device class didn't actually matter here). This didn't work out of the box, the newly created project didn't actually enumerate properly with the host.I spent a couple of hours debugging this issue, until I figured out that the interrupt handler wasn't actually called, which is why the device didn't react to USB.I found a checkbox in the Pinout&Configuration tab, under Con

Greetings,I am having difficulties with connecting to my STM32H745IIK6. Normal mode doesn't work as well as Connect under reset. NRST pin works as it halts the program, and the program is running normally otherwise.But the weirdest thing is that connecting the BOOT0 pin to +3V3 and reseting the MCU doesn't cause it to boot from System memory, it still boots from Flash memory and runs the program. I haven't changed any BOOT option bytes.Does anyone know the solution to this?BRDomagoj

Hi all, i have a problem to receive data from USB.use STM32L476.As for the transmission, everything works smoothly. but when i try to send a packet i can't find the arriving data, the byte length is correct, but i don't understand where the buffer is pointing to read my data. I am attaching the code I wrote:static int8_t CDC_Receive_FS(uint8_t* Buf, uint32_t *Len){ /* USER CODE BEGIN 6 */uint32_t received_data_size;   USBD_CDC_SetRxBuffer(&hUsbDeviceFS, &Buf[0]);   USBD_CDC_ReceivePacket(&hUsbDeviceFS);   received_data_size = *Len; // my   memcpy(aRxBufferUSB, Buf, received_data_size); // my   CDC_Transmit_FS(Buf, *Len);         // try echo    return (USBD_OK); /* USER CODE END 6 */}aRxBufferUSB th

Hello,I'm trying to change the HID report to x and y have more accuracy (If i', not wrong, windows drivers accept this without any proprietary driver).My HID mouse report in usbd_hid.c is:__ALIGN_BEGIN static uint8_t HID_MOUSE_ReportDesc[HID_MOUSE_REPORT_DESC_SIZE] __ALIGN_END = { 0x05, 0x01, // Usage Page (Generic Desktop Ctrls) 0x09, 0x02, // Usage (Mouse) 0xA1, 0x01, // Collection (Application) 0x09, 0x01, // Usage (Pointer) 0xA1, 0x00, // Collection (Physical) 0x05, 0x09, // Usage Page (Button) 0x19, 0x01, // Usage Minimum (0x01) 0x29, 0x05, // Usage Maximum (0x05) 0x15, 0x00, // Logical Minimum (0) 0x25, 0x01, // Logical Maximum (1) 0x95, 0x05, // Report Count (5) 0x75, 0x01, // Report Size (1) 0x81, 0x02, // Input (Data,Var,Abs,No Wrap,Linear,Preferred State,No Null Position) 0x95, 0x03, // Report Count (3) 0x75, 0x01, // Report Size (1) 0x81, 0x01, // Input (Const,Array,Abs,No Wrap,Linear,Preferred Sta

I recently learned to use FreeRTOS on STM32F7. The program runs for a certain period of time and then enters HardFault_Handler. The time is variable.The fault analyzer is reporting an error as "FORCED" and "PrecisErr". There are 6 threads in the project.Print time per second in thread A;Thread B is responsible for sending commands from USART1.Thread C receives data from USART1 and sends data to Thread D, Thread E, and Thread F via the queue.Thread D is responsible for obtaining the data sent by C through the queue, and sending the result to thread F through the queue after data processing.Thread E is responsible for saving the received data to the SD card;Thread F is responsible for sending the received data through usart2.Where the thread priority from large to small is C=E>D>F>B>A.The stack space used by each thread is set at around 10*1024. The attached picture is the situation of each thread captured during the program running, among which the thread G

Hello, I am trying to implement TCP and UDP server connection on my STM32F407-Discovery Board. I use Socket API with FreeRTOS. I am able to run TCP or UDP seperately. Single server or client works fine. When I combine TCP and UDP server tasks at the same code. None of them work. I can not even PING my STM32 board. I created different two tasks for each TCP and UDP server.I tried to increase HEAP size of LWIP above 32KB. However, it did not resolved my issue.Are the any solution to my issue ? Thank you in advance for your help. Best Regards

I want demo code for STM32F746 Discovery kit as per follow.1) using lwip for TCP Server / Client.2) Not using RTOS.Demo code available for STM32F756-EVAL at Projects\STM32756G_EVAL\Applications\LwIP\LwIP_TCP_Echo_Client.This demo code is perfect but i don't have this board, I have STM32F746 Discovery board.Both have different PHY IC. And one with MII and another is on RMII.So is there any example / demo code for STM32F746G-DISCOVERY for TCP server/client without RTOS..?

Hello All, i am using Quctel EC21 GSM Module i need help regarding how to store AWS Certificate into the Code and Send this certificate using AT Command if anyone have example code for AWS MQTT using AT Command that is very helpful for me thank you in advance

Hello, I'm using the STM32L476RG and trying to receive data via UART.When I use the following code:int main(void){ ... HAL_UART_Receive_IT(&huart4, data_RX,20); ....}void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart){ printf("\nMessage received is: %s",data_RX);}This works just fine if ONLY the message received is 20 characters long. But not if the message is for example 15. I know that when my data_Rx is full, it then will be printed.I was wondering if anyone came across this problem and was successful implementing a solution. I tried some of the codes I found on the internet, but lot of them where really confusing.Sorry if this topic was already discuss. Any help would be awesome!Thank you.

I'm studying about the DFU mode to use this.​So I'm looking for documents, but I'm confused whether the DFU mode and BOOT Loader are different or the same.​I think,​There is ​various ways to communicate with the MCU in Boot Loader state like UART, I2C, CAN, USB...​And if i want to use USB to communicate with the MCU, i need to use USB in DFU mode.So, in device manager, When i connected MCU using USB cable, PORT must be appear as a STM32 BOOT Loader.​But, it sometimes appears as a bootloader or as a DFU.​what is the difference between BOOT Loader and DFU mode??​​​I'm sorry if my words were awkward, I used a translator. ​

I installed STM32CubeMX 6.2.0, the STM32CubeH7 1.9.0 and the X-CUBE-AZRTOS-H7 thinking that I would do Azure RTOS projects as I did using FreeRtos. Why didn't ST put Azure RTOS and its components as a midware option? As it does for FreeRtos.How to use the X-CUBE-AZRTOS-H7?

Hello,I'm trying to add 5 more buttons in a mouse, to do this, with the Device configuration tool I have enabled the usb as HID (no Custom HID).To add the buttons i changed the HID_MOUSE_ReportDesc:0x05, 0x01, // Usage Page (Generic Desktop Ctrls) 0x09, 0x02, // Usage (Mouse) 0xA1, 0x01, // Collection (Application) 0x09, 0x01, // Usage (Pointer) 0xA1, 0x00, // Collection (Physical) 0x05, 0x09, // Usage Page (Button) 0x19, 0x01, // Usage Minimum (0x01) 0x29, 0x08, // Usage Maximum (0x03) 0x15, 0x00, // Logical Minimum (0) 0x25, 0x01, // Logical Maximum (1) 0x95, 0x08, // Report Count (3) 0x75, 0x01, // Report Size (1) 0x81, 0x02, // Input (Data,Var,Abs,No Wrap,Linear,Preferred State,No Null Position) // 0x95, 0x01, // Report Count (1) // 0x75, 0x05, // Report Size (5) // 0x81, 0x01, // Input (Const,Array,Abs,No Wrap,Linear,Preferred State,No Null Position) 0x05, 0x01, // Usage Page (Generic Desktop Ctrls)

Hi,I have an application running on the stm32F072C8U6.It has a 'bootloader' application at 0x08000000, which successfully jumps to the 'real' application, at 0x08004000. after vector remap, GPIO USB Keypad works fine, but when PC send a message by USB CDC. it caused the MCU out of work.

I am having working tcp/ip project using lwip on STM32F7 using which I can send RAW data.Now I want to send text file from SD card to local server.How can I implement this.

Hi all,In my project I need to read an ADC at a sample rate of 15KSPS. When new data becomes ready to read, the ADC pull low the DRDY line. I've configured this line as input interrupt and in the ISR a signal is sent to a task waiting for it before to do some calculation. It works well, but the call to osSignalSet take about 15usec to be executed that is too much for my goal. Is there a way to speed it up? The MCU clock is 168 MHz.Thanks in advance for any help.
