STM32 MCUs Products

Hi friends,I have to configure Sleep mode  and Wakeup mode in  STM32F103C8T6 and STM32F407VET6 using RTC .But i  did not know how to configure this process .I need your guidance how to configure this by using datasheet and one important point is i have to use only internal clock for my configure. Thank you for advance for yours response

I am using a 32 MHz crystal with STM32U595 and I noticed that selecting HSE/2 (16 MHz) as OTG HS Clock Mux source results in USB_CoreReset() getting stuck in the loop waiting for the reset to complete:  do { count++; if (count > HAL_USB_TIMEOUT) { return HAL_TIMEOUT; } } while ((USBx->GRSTCTL & USB_OTG_GRSTCTL_CSRST) == USB_OTG_GRSTCTL_CSRST); Other configurations of OTG HS Clock Mux, appear to work:- PLL1P configured to 16 MHz- HSE with OTG PHY reference clock selection set to 32 MHz Here is my complete clock tree, which doesn't work - just switching OTG HS to PLL1P resolves the issue:

I am a fan of STM32, especially the peripheral sets offered are great. Over the years however, one type of peripheral is missing which would be a great help for many projects, this is a programmable logic cell.Such a cell would contain elements like Flip-Flops, Look Up Tables and such that can be configured for specific functions. For instance using the LUT's, it would be possible to create all kinds of logic operations like AND, OR, XOR gates.Using the Flip-Flops, I would be able for instance to create a clock gate, which I needed in my last project. There I needed an external clock signal to propagate to other peripherals and be able to enable/disable this. In the end I manage to create this function with a timer but this unfortunately generates something like 9 clock cycles of latency limiting the maximum frequency of the external clock signal. A basic Flip-Flop solution would probably introduce a much smaller latency.Competing products offer this kind of fun

Hello,The TFM application that is based on the stm32u585 board could work for the stm32u575zit6 microcontroller? I have modified the TFM project and I have removed hw accelerator from the SBSFU project because the u575 microcontroller does not contain this peripheral but in the TFM_Appli application I get cryptographic errors when building the project.Thanks in advance

hi ALLI use stm32h753.1) SPI1 , DMA , DMA1_Stream0 2) HAL_SPI_Transmit_DMA(&hspi1, gAudioTxBuffer, VS1063_DMA_TX_LEN);3) void SPI1_IRQHandler(void) interrrupt ==> Very wellbut1) SPI6 , BDMA , BDMA_Channel02) HAL_SPI_Transmit_DMA(&hspi6, gAudioTxBuffer, VS1063_DMA_TX_LEN);3) void SPI6_IRQHandler(void) not interrrupt => not interruptI don't know why spi6 doesn't get interrupt. Do you know why? Please tell me how to solve it Thanks. 

Our product uses a STM32H7xx chip, integrate freeRTOS. We want our product can go into STOP mode to save power, and can be waked up from STOP by USART3 receiving data.Below is some related code, but it does not work, our product can't be waked up by USART data.  MX_USART3_UART_Init is generated by CubeMx, we just add a few code at the beginning and end to config WUS clock and IT.void MX_USART3_UART_Init(void){/* USER CODE BEGIN USART3_Init 0 */__HAL_RCC_WAKEUPSTOP_CLK_CONFIG(RCC_STOP_WAKEUPCLOCK_HSI);/* 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

Hello,I am connecting STM32V2 debugger at following pins.  This supports SWD. I want to use JTAG pins and want to use STM32V2 debugger as a JTAG connection for debugging purpose. can you support me how to connect or which pins to be used and what is the procedure to change from SWD to JTAG mode? Regards,Nikhil  

Hi!I have a problem with the canbus gateway project, I have a very good ring buffer that works without delays and transfers data between can1 and can2. All data copying is done through the main while loop where I check the buffers for can1 and can2 to see if there is anything to send and handle it. The project works great, but after 2-3 hours of driving, strange anomalies start to happen... There is a second delay in data transfer, when I press the reset button on the art-pi board, everything returns to normal and works properly for the next 2-3 hours. I thought it might be a buffer overflow problem which can hold 512 messages for each can. However, when I turn off the vehicle and after a minute there are no frames on the bus and I restart the vehicle, the delay is still there... So it's not the buffers' fault. Has anyone encountered such a problem?

Hello everyone,So I am trying to take Input from the sensor and then turn on the LED_1/Sound on and another senarove is that whne I prace the GPIO_EXTI1 turn on the another LED_2. but what is hapning is when senser is not givin Input even then LED_1/Sound is on.Bun whin i use the TWO code sepratly THe code work with no problem 1. while (1) { /* USER CODE END WHILE */ /* USER CODE BEGIN 3 */ if (!button_pressed) { handle_sensor_input(); } } // Handle sensor input 2. void handle_sensor_input(void) { GPIO_PinState a = HAL_GPIO_ReadPin(SENSOR1_PORT, SENSOR1_PIN); GPIO_PinState b = HAL_GPIO_ReadPin(SENSOR2_PORT, SENSOR2_PIN); // Process the sensor state if (a == GPIO_PIN_RESET || b == GPIO_PIN_RESET) { HAL_GPIO_WritePin(GPIOA, GPIO_PIN_3, GPIO_PIN_SET); HAL_Delay(100); int randomIndex = rand() % size; int randomNumber = numbers[randomIndex]; printf("Randomly selected number: %d\n", randomNumber); sel

HiWe are using STM32H573 in our devices. Recently we have started to face an issue where once we flash the device the MCU stops working and when we try to connect to the cube programmer to re flash the board, the cube programmer shows no target found.I have a feeling that the MCU is hung as I was able to find two GPIOs, one being pulled high, and the other being pulled low. Is there a way to get the board re flashed? I have tried making the BOOT0 pin high and connect to programmer but of no help.Pls let me know if there is a way to debug and resolve this problem. I have 3 boards with the same issue.Programmer: ST-Link V2Regards,Nikhil 

Hello,I have an application where I transfer data to and from a PC with a FT232R and a UART. There is data beeing transfered back and foth constantly and asynchrone to another, so it is sending and receiveing at any random time and simultaneously. Sending and receiving is done by interrupt and use the same interrupt (checking in the interrupt which flag is active). I noticed that there was something wrong and toggled a pin each time the UART reived a byte. The problem is that it occaseonly misses some single bytes. This is when there are several hundred bytes transmitted to the STM32 at the maximum rate without delay between the bytes. Generally the UART is supposed to be fullduplex. The interrupt routine is shorter than a byte. So maybe the sending and receiving on the same interrupt is causing this.I wondered now if it is possible to send the bytes not by interrupt but by using a DMA with a DMA finished interrupt while receiving the bytes with the UART interrupt? It

Hi     Can anybody guide me to choose right STM chip for camera interface and parallel display interface,   Thanks  

I started getting this message when I try to debug my code. However, there are currently no breakpoints in my code at all. I have gotten this in the past and I deleted and redownloaded the IDE which I really do not want to do again. I am running it on Mac.

          Hello! I dont know where to find received data after HAL_I3C_Ctrl_Receive_IT progress.          I set I3C of my H563 as master and sent ENTDAA and master read , the slave answered both command. The interrupt of slave reflects that master read is done and the data in tx-fifo is transferred correctly. But when i read RxBuffer of the HAL_I3C_Ctrl_Receive_IT i find nothing but 0.          Can anybody help me?Thanks!

Hello,I have configured a DMA channel to perform a memory-to-memory transfer triggered by EXTI. I would like to automatically re-arm channel at the end of every completed transfer so that it is ready to process the next EXTI trigger event without any CPU intervention. What are the possible avenues to achieve this goal?Thank you very much for your assistance,P-M

I'm trying to see what's possible in terms of a bootloader in a custom application of an stm32f722. We have an external 2-megabyte flash chip on the QSPI bus, along with the internal 512-kilobyte flash.  I'd like to make the bootloader stored on internal flash as tiny as possible; the best way to do this is to make it evaluate the image stored on internal flash as well as external, and simply jump to whichever one passes this evaluation.  I'd then put the code to handle USB DFU mode, SPI download mode, UART download mode, etc., all on the external flash, and run it from there only if needed. This requires being able to write that code into the external flash using SWD (further upgrades can be done over any of the protocols above, but for the first time we need to use SWD as the code isn't on the device yet to do the other protocols).  What I can't tell is whether the SWD implementation on this chip allows writes to flash chips map

HelloWhen adding the internal temperature sensor reading in the STM32H750 micro FW, out of curiosity I collected voltage reading data based on different sampling times.Based on our ADC clock speed (37.5 MHz) and the datasheet requirements for the temperature sensor (minimum sampling time 9 us) I calculated that the minimum cycles required for the ADC sampling are 337.5.This works out well and with the sufficient sampling time provided I obtain appropriate temperature reading of 27C.Now it seems understandable that when not enough sampling time is provided, the internal ADC SAR capacitors do not have enough time to char

Hello,I am working on a project with STM32H753XI mcu and with external interrupts. The problem is that I cannot take an interrupt to PIN PB2. Specifically:1.The Pin is configured as Rising Edge Interrupt (Also tested as falling edge and rising falling edge).2. The Interrupts in EXTI Line 2 are enabled with high priority. (I have tested to PI2 and I can take the interrupt).3. The clock to port B is enabled. 4. I can read The Pin changes of the status (High-Low) from mcu. (I have tested this with the GPIO debbuging tool from keil and I see the changes and also with Polling the Pin). The problem is that the mcu do not enter the callback function. I have tested with other pins and the mcu enters the callback function and all the system working as expected. Any Ideas?Thanks In Advance, 

Posted on December 28, 2016 at 07:18Hi,I think you might familiar with  this issue if you are proficient user of Eclipse +STM32.In my #include section of main.c file.Red error line indicates like :(,At the same time the system says to do indexer marker, :(Kindly suggest me what to do for this issue?

While connecting the battery, the ground was inverted with the VCC and vice versa. As a result, this capacitor burned out. I need to know the function of this part and if I can continue to work normally after what happened.
