Hello,I need the BSD-File for STM32L151RCT6 for Boundary Scan. Does anyone know, where I can get it? In the recources section I can only find an older .zip file with bsd files for other processors.Thanks.

Hi. I am working on creating parallel threads on my STM32U5G9J-DK2 board using freeRTOS. Are there any freeRTOS example projects for this devkit I can reference? I could not find any while creating a project in the STM32 Cube IDE.Thanks, Michael

Hello, I’m working with an STM32L412KB on an evaluation board, and I’m facing an issue with receiving UART data. Here’s a quick overview:Setup: The device receives 5-byte packets over UART every 30 ms using the HAL UART interrupt mode (HAL_UART_Receive_IT).Issue: After running for a few minutes, the received packet occasionally gets corrupted—typically with the first and last byte becoming swapped or confused.Attempted Fixes: I’ve cleared error flags in the HAL_UART_ErrorCallback, and I’m restarting UART with DMA after an error, but the corruption persists.I have tried DMA and circular buffer, but the results are the sameBelow is a code example showing the logic (I cannot share the actual code due to NDA constraints):. HAL_UART_Receive_IT(&UART, packet, BUFF_SIZE); // Initiate UART receive in interrupt mode void H

I am trying to interface a STM32H563 to an LCD using the ST7789v controller over SPI.To test I'm just sending the LCD initialization as specified by the datasheet shown below...//-------------------------------Hardware reset-----------------------------------//LCD_Reset = 1;Delay_Ms(1);LCD_Reset = 0;Delay_Ms(10);LCD_Reset = 1;Delay_Ms(120);//-------------------------------Software reset--------------------------------------//SendIndex(0x01);Delay_Ms(120);//------------------------------ Sleep Out--------------------------------------------//SendIndex(0x11);Delay_Ms(120);//--------------------------------Display setting--------------------------------------//SendIndex(0x36);SendData(0x60);SendIndex(0x3a);SendData(0x06);//-----------------------------ST7789VI Frame rate setting--------------------------//SendIndex(0xb2);SendData(0x0c);SendData(0x0

Hello, Currently I am trying to configure SPI with DMA, where i am only using DMA for Transmit and Not for Receive, I have generated the code through STM32cubeIDE, i have c=external clock at 16mhz and my Baud rate is 4Mhz. i am not using any SPI interrupt. DMA interrupts are by default enabled I am using SPI for writing into FRAM.  My code is misbehaving like sometimes it will write and sometimes not. Sometimes it will read sometimes not. I am not able understand the reason. Basically, it's not working properly

Hello,I'm migrating the code from stm32f4 to stm32h7 and stuck with SDMMC ACMD51 command. This command reads SD configuration register via data lines (8 bytes total).Is there is any way to configure this request to set DBCKCEND flag when it receives all bytes? Or FIFO flags polling only the way?Here is my attempt to do it: #define SDIO SDMMC1 #define SD_ACMD51 51|SDMMC_RESPONSE_SHORT|SDMMC_WAIT_NO|SDMMC_CPSM_ENABLE|SDMMC_CMDTRANS SDIO->DTIMER = 0xFFFFFF; SDIO->DLEN = 8; SDIO->DCTRL = SDMMC_DCTRL_RWSTART|(3<<SDMMC_DCTRL_DBLOCKSIZE_Pos)|SDMMC_DCTRL_DTDIR; result= sdio_send_acmd_blocking(SD_ACMD51, 0); if(result!=0) return result; result = wait_for_sd_data_ready(); //waiting for DBCKCEND interrupt  

Hi,We have a working ( if we can say so ) firmware.The issue is that everytime he calls the build option (IAR EWARM) he calls, at the end, the cubeprogrammer utility that adds the CRC area to the firmware in post-build. The from-to memory region he selects is correct. The issue here is that everytime the build option is called a new CRCs Area with the same VMA (Virtual Memory Address) is created, so obviously CubeProgrammers reads the file as corrupted/not valid. Is this a bug or something else? 18 CRCs area 000001f8 0801f608 0801f608 0034ee5d 2**2 CONTENTS, ALLOC, LOAD, DATA 19 CRCs area 000001f8 0801f608 0801f608 0034f055 2**2 CONTENTS, ALLOC, LOAD, DATA 20 CRCs area 000001f8 0801f608 0801f608 0034f24d 2**2 CONTENTS, ALLOC, LOAD, DATA 21 CRCs area 000001f8 0801f608 0801f608 0034f445 2**2 CONTENTS, ALLOC, LOAD, DATA  

Hi everyone!I am having a hard time making my design work.I prepared a long list of what I did and what I observed to paste into ChatGPT.I am pasting the exact text below:I designed an digital circuit using STM32F417VGT microcontroller.I applied 3.3V to all VDD, VDDA, VBAT and VREF+ pins.I connected all VSS and VSSA pins to the circuit ground (GND).I connected all required bypass capacitors to the power pins as instructed in the datasheet.I added 2.2uF/6.3V ceramic capacitors to the both VCAP pins.I added 32.768kH and 25MHz crystal oscillators to the correct clock pins.I connected the BOOT1 pin to GND.I tried connecting the BOOT0 pin to VDD and GND at separate times.I have several similar designs, which I previously designed before this one.In these similar designs, I exactly did the same conne

Hi All,  I want to read all ADC channels from the nucleo c031C6 using DMA all channels should be read continuously. For example 1k samples per seccond. I have tried to configure lots of different approaches in the CubeMX, but I can not figure it out. Can anyone give me a hint on how to set ADC and DMA settings in CubeMX? Cheers 

Hello everyone, I'm working with the STM32F103RB controller and have encountered an issue with the RTC functionality. While the time continues to update correctly when powered off (with VBAT enabled), the date resets to the default 01/01/2000 instead of retaining or updating the current date. Has anyone experienced this behavior before, or can provide guidance on why only the time updates but not the date? Any advice on possible solutions or steps to troubleshoot would be greatly appreciated. Thank you in advance for your help!

I’m interfacing the STM32H755ZI-Q Nucleo board with an MTFC8GAMALNA-AAT eMMC. What configurations are necessary for this interfacing? I’m also getting warnings in the RCC configurations. Could you guide me on the settings needed for SDMMC1 and FATFS, and let me know if there are any additional configurations required?

Hello, Can I know any available settings to reduce I/O speed. The idea is to reduce power consumption by F429. CubeMX doesn't allow to change I/O speed.

We are trying to transmit data using SPI6 and BDMA.When we perform the following process, we are able to transmit 1 byte + 1 bit of data, but after that, MISO outputs High no matter what the value of the transmitted data is. What is wrong with this?   #define __ATTR_RAM_D3 __attribute__ ((section(".RAM_D3"))) __attribute__ ((aligned (4))) uint8_t g_spitxbuf[4] __ATTR_RAM_D3; // DCDC基板温度センサ模擬_送信バッファ uint8_t rx_buf[2] = {0}; uint8_t tx_buf[2] = {0}; /* SPI3_CS High出力 */ HAL_GPIO_WritePin(GPIOF, GPIO_PIN_6, GPIO_PIN_SET); /* SPI3_CLKを有効 */ __HAL_SPI_ENABLE(&hspi5); /* SPI3_CS Low出力 */ HAL_GPIO_WritePin(GPIOF, GPIO_PIN_6, GPIO_PIN_RESET); g_spitxbuf[0] = 0xA5; g_spitxbuf[1] = 0x00; g_result = HAL_SPI_TransmitReceive_DMA(&hspi6, g_spitxbuf, rx_buf, 2); g_result = HAL_SPI_TransmitReceive(&hspi5, tx_buf, rx_buf, 2, 1000); /* SPI3_CS High出力 */ HAL_GPIO_WritePin(GPIOF,

Hello, I'm using H723 Nucleo. I set 5 ext interrupt pins: PA0, PA1, PA4, PC2_C, and PC13 as EXTI to 5 switches, enabled NVIC interrupt, GPIO pull-up,  interrupt with rising edge triggered, and tied these 5 pins to switches with the other end to ground. The code is working fine, but I observe that only 1 interrupt (either 1 of the 5 switches) can work at any one time, and all 5 interrupts cannot work together at any instance... is this interrupt conflict on H7? Anyone can advise?      if (GPIO_Pin == GPIO_PIN_0) { // on LED1 }    

   

Hello,I'm wondering if there's a way to use the DSIHOST_D1P and D1N pins as GPIOs, or if it's possible to simulate GPIO functionality on these pins. Currently, I don't see any GPIO configuration options for them in STM32CubeMX. The MCU in use is the STM32F469ZIT6.Any insights would be appreciated!

Using the STM32U083C-DK discovery board with STM32CubeIDE and set up the project using the Device Configuration Tool.Set up a simple program to transmit 8-bit data out one UART using interrupts and receive it in another UART using DMA.Variables used:Relevant main.c code:The

I am writing my own SPI driver, and using two B-L072Z-LRWAN1 boards to test them; one as an SPI master and one as a slave. On the master device, whenever I enable the SPE bit in the function SPI_Transmit(), it never actually sets to '1', even though the configuration registers are set to the programmed values. Why is this?Here is the initialization function for the slave device. I am using the HAL SPI handlers so I could debug the SPI registers: void SPI2_Init_Slave(SPI_HandleTypeDef * hspi) { /************** STEPS TO FOLLOW ***************** 1. Wait for the TXE bit to set in the Status Register 2. Write the data to the Data Register 3. After the data has been transmitted, wait for the BSY bit to reset in Status Register 4.

Hello Everyone,Is there any plan for ST to provide support drivers for the MX25L6433F serial NOR flash on the STM32H5 series of micros?MX25L6433F is the flash used on the X-NUCLEO-GFX01M2.Thanks. 

Hello STM32 Community,I’m working with a custom board featuring the STM32H725ZGT6, and I’m encountering some issues I hope you can help with. Out of the 10 boards I've assembled, 7 are functioning perfectly. However, on a few boards, the MCU isn’t being detected in STM32Cube Programmer. When it does get detected, I receive the following error (screenshots attached).To troubleshoot, I’ve attempted the following:Reflowed the MCU with hot air and checked/reballed the pinsTested the MCU on another working board (still facing the same detection issue)Replaced the MCU with a new one on the problematic board (issue persists)Has anyone experienced similar issues or have suggestions on what might be causing this inconsistency? Any guidance would be greatly appreciated!

Hello,I am using the SPI on the STM32H743ZITx as a SPI Master in Full-duplex mode to transfer large data packets (1600 bytes). But instead of seeing the data being transferred in a constant burst, I see it being sent out a byte at a time with gaps in between, apart from a burst at the start of the SPI transaction.Here is my SPI3 settings in STM32CubeIDE, v1.16.1:The SPI initialization is the default MX_SPI3_Init() provided by Core/Src/spi.c in STM32CubeIDE.I am using the interrupt transfer method. My code is as follows:// TxRx complete callback void HAL_SPI_TxRxCpltCallback(SPI_HandleTypeDef *hs
