I need to use SD Card in my project because of my mcu has not enough memory space. I need 200MB free space so i want to use SD Card. My html,css, js files are big size. When I convert my html,css,js files to C file (fsdata.c), that file be more than 150-200MB. My MCU memory just 1MB. How can i do it? I looked FATFS-LWIP application in st code but it didnt help to me. It is basic example (i can not do anything with html,css,js file in this example). Please if you have any idea or advice, help to me :)

In Project Explorer view, I have my project directories shown as drop down lists.In >Core, my project used to show >Inc, >Src, and >Startup. Somehow >Src is no longer in the list, yet it is included in the build. I use Windows Explorer to verify that Core in fact does include these 3 sub-directories, the Src one is simply not showing in the Project Explorer view. How to make it displayed again????

I use the CubeMX in batch mode on a "nightly buid machine" without an internet connection. Now with CubeMx version 5 there is always a dialog box "Proxy Error" popping on which prevents the further processing of the batch file so that the code could not be created and tested. Is there a way to get off that dialog box ?

I have a custom board with STM32F302C8T6. I generated a custom HID project by CubeMX(STM32Cube_FW_F3_V1.11.3), and found that only two packets could be received if "USBD_CUSTOM_HID_SendReport" is used to send data back to host.Here are some more details:1. 0.zip is the original code generated by CubeMX. 305dea60e57af8b78b4e49039b6e2bd1fcf512cc.zip is the modified version. You can compare to see the difference. Also, you could see diff.diff to difference.2. In windows10 x64, I use a modified version of hid_test to test custom HID read/write. Please see "test.c" for details.3. In CUSTOM_HID_OutEvent_FS, if "USBD_CUSTOM_HID_SendReport" is called, the first two hid_write and hid_read_timeout will succeed. The following hid_write will fail. Also CUSTOM_HID_OutEvent_FS will be called only twice.4. If "USBD_CUSTOM_HID_SendReport" is not called, hid_write from host will always succeed (and CUSTOM_HID_OutEvent_FS will be called successfully also).

Hello,I'm trying to do the memory position jump using this code:JumpAddress = *(__IO uint32_t*) (APPLICATION_ADDRESS + 4); Jump_To_Application = (pFunction) JumpAddress; __set_MSP(*(__IO uint32_t*) (APPLICATION_ADDRESS )); Jump_To_Application();I managed to make it work with only one GPIO, but when I add peripherals in the bootloader, it no longer works.I'm trying to de-initialize the peripheral, a UART has this reference (stm32f4xx_hal_uart.c):/** * @brief DeInitializes the UART peripheral. * @param huart Pointer to a UART_HandleTypeDef structure that contains * the configuration information for the specified UART module. * @retval HAL status */ HAL_StatusTypeDef HAL_UART_DeInit(UART_HandleTypeDef *huart) { /* Check the UART handle allocation */ if (huart == NULL) { return HAL_ERROR; }   /* Check the parameters */ assert_param(IS_UART_INSTANCE(huart->Instance)); &nbsp

[STM32CubeIDE Advanced Debug Features]https://www.youtube.com/playlist?list=PLnMKNibPkDnEDEsV7IBXNvg7oNn3MfRd6The STM32CubeIDE can be used to create applications for STM32 devices using STM32Cube libraries (HAL and Low Layer versions) and this video series will cover the features for debugging one simple application firmware using that as the basis and augment the debug experience by using the Instrumentation Trace Macrocell (ITM) and the Serial Wire Viewer (SWV) with several different hands-on sessions to explain all possible views and setups in the debug session.Benefits you will take away:• Understand the hardware needs to use the SWD + Serial Wire Output (SWO)• Understand differences between SWD and JTAG, and w

My Firmware Package name and version: STM32Cube FW_F1 v1.8.4Bug detail: After code generates, the code order is:In this order, receiving message of the usart will get some bugs, eg: only can receive the last byte...I let `the MX_DMA_Init();` become the first one solve the problem, but when I genearted code next time, this order will appear again...

Hello,I'm Using STM32H7A3RIT MCU and I'm trying to communicate to 5 sensors at a time, through the UART interface. I configured 5 UARTS in my MCU. But I'm facing some issues while transmitting and receiving from all these at the same time. Is it possible to receive UART data from different UART peripherals at the same time? currently, I'm receiving data in interrupt mode. Is it possible or Do I need to use DMA?--Thank you in advance.

Hello. I would like to print certain messages to UART only in DEBUG mode. These prints will not be necessary in release mode.I have tried the following:#ifdef DEBUG printf("hello from debug \n"); #endifAnd then I have built the project for both release and debug but the message is printed in both cases. How can I only get message to print in debug mode and not in release mode?

I want to use the FLASH bank-swap feature of the STM32H753 for custom firmware updates. I have no problem erasing and programming FLASH bank 2 when running from bank 1 but I get a double bus fault when attepting to erase a sector in bank 1 when running from bank 2. I check SWAP_BANK in FLASH_OPTCR before erasing to determine which bank is currently being run from. I've double checked with STM32Programmer to make sure I'm running from bank 2 and have single stepped in CubeIDE to verify I'm attempting to erase sector 0, bank 1.Has any one else come across this ?ThanksDave

When I set up the USB_OTG_FS peripheral in CubeMX I get the following error: Looking at CubeMX I can't see anything wrong. The only thing I noticed is that I can't enable VBUS Sensing. The only option is "disabled". It has a pin assigned for it, the box is ticked, but the drop down (highlighted above) only has "disabled" as the single option.Edit: I sho

Hi All,I need some help and guidance as to how I can read data off UART sensor?I have tried to following many instructions from my professor and from online but have been so far unsuccessful at obtaining any data. Currently doing testing through CubeIDE and have the STM32F411RE plugged into my pc through USB and am able to transmit and receive data using TERA TERM but cannot get any readings to show from the sensor. I am wondering if I'm at all reading correctly? Can I read data from the sensor while plugged into my PC, similar to I2C?If not how should I read data from the sensor? Please see my current code below.Oh and we have to use LL Logic not HAL!uint8_t USART2_GetChar() { uint8_t data;   data = RxBuffer[RxTailIndex]; // read the character indexed by RxTailIndex (ie the oldest valid character in the buffer) RxTailIndex++; //increment the tail index (now po

I have a random strange delay on SPI2 callback function on my SPI slave application.Normally the function is called regular after interrupt handling without delay but casually is affected by 1ms delay before its execution!void HAL_SPI_TxRxCpltCallback(SPI_HandleTypeDef *hspi) { if(hspi->Instance==SPI1) // SPI MASTER { ACC_ADXL_355.wTransferState = TRANSFER_COMPLETE; ACC_ADXL_345.wTransferState = TRANSFER_COMPLETE; ACC_MA_352.wTransferState = TRANSFER_COMPLETE; ACC_ADIS_16209.wTransferState = TRANSFER_COMPLETE; } else if(hspi->Instance==SPI2) // SPI SLAVE { SamplingData.SPI_Slave.wTransferState = TRANSFER_COMPLETE; } }This make an error on SPI slave response and the master receive a wrong data packet.Do you have any suggestion to avoid this condition and call this function wiyhout delay?uP part number: STM32L071CBTx

I am trying to read IMU sensor data using SPI. I have generated the code and I could verify that I am able to read SPI data while using the function HAL_SPI_TransmitReceive. Later, when I tried using the HAL_SPI_TransmitReceive_DMA function with the same Rx and Tx buffers, I am unable to see any signals on the SCK, MISO, MOSI lines. I have configured the DMA for TX and RX with high priority, Normal Mode, Data width as byte. Can you please give me hints on what to check for?

Hello,I seem to be having some problems with the code generated via STM32CubeMX on the NUCLEO-H743ZI development board. I want to configure it to run on LwIP/RAW API. I can create such a configuration for its close relative: the NUCLEO F767ZI development board. In the latter case I take the following steps: Set the HCLK to 216 MHz (clocked from the HSI);Enable the ETH peripheral, set it to RMII mode, and set ETH_TXD0 and ETH_TX_EN pins to PG13 and PG11 (others are mapped appropriately); Set the PHY address to 0 in ETH Configuration>General: Ethernet Configuration Enable the LwIP middleware;Enable ICMP (LWIP_BROADCAST_PING and LWIP_MULTICAST_PING in LwIP Key Options>IPMP Options). This step is not necessary, although it helps to determine if all is well with the device.After I generate the code, I add an extern variable to my main.c to be able to track whether the device has obtaine

Hello,I'm looking for MTP class in USB Device library but did not find it in cubeMXIDE, would you please let me know if this is possible to implement MTP in USB Device mode.Thanks

I am working on STM32H7532ZIT6 – NUCLEO H753ZI. Trying to connect LTE modem (Quectel EVal board ) via USB I/f using a female connector in between. Programmed STM as USB host at 48MHZ and disabled VBUS. I see that the Enumeration fails as the API USBH_Get_DevDesc. Tried sample code online from several sites and none works

According to my experiences, STM32CubeIDE (1.9.0) does not support SWV message via ITM when using ST-Link GDB server, but it does so via OpenOCD. However, Keil µVision 5 does support ITM tracing, even bidirectional, via the 'Debug (printf) Viewer', when selecting the ST-Link option. What driver is Keil using that STM32CubeIDE isn't?

In STM32CubeMX, version 6.3.0, using STM32CubeF4 v1.25.2, when a SPI port is set to mode "Receive Only Master", it sets `hspi#.Init.Direction = SPI_DIRECTION_2LINES_RXONLY;` in generated code, as (I think) it should. However, the generated code doesn't work for DMA mode (`HAL_SPI_Receive_DMA()`). The SCK doesn't shut off at the end of the requested transfer, and the `HAL_SPI_RxCpltCallback()` interrupt handler doesn't hit.If I set the SPI mode in CubeMX as "Full-Duplex Master", then manually change `hspi#.Init.Direction = SPI_DIRECTION_2LINES;` to `SPI_DIRECTION_2LINES_RXONLY` in the generated `MX_SPI#_Init()`, the bad behavior is the same. I can optionally remove the call to `HAL_GPIO_Init()` for the MOSI line, and it still works, though.Is this an issue with the CubeMX-generated code, the HAL, and/or the Silicon itself?(I realize I'm not using the latest CubeF4 HAL, and we're working on updating that. Meanwhile, I checked the diff against
