STM32 MCUs Products

Hii,Can someone please help me out in configuring QSPI in DTR mode to read and write data to the external QSPI memory. What all configurations are required to change to switch from STR to DTR? I am using STM32F469xx MCU with MT25QL128ABA NOR Flash in STM32CubeIDE.

Hello,I'm designing a pcb with a STM32L031 MCU. I will use serial UART2 for bootload and debug.In ST application note nº2606 and "STM32L031x4 STM32L031x6 datasheet", it is said :"The boot loader is located in System memory. It is used to reprogram the Flash memory byusing SPI1 (PA4, PA5, PA6, PA7), USART2 (PA2, PA3) or USART2 (PA9, PA10). SeeSTM32™ microcontroller system memory boot mode AN2606 for details."My question is : Is it possible to flash the device with USART2 but with USART2_TX located on PA14 and not PA2 ?My application context makes it mandatory insofar as PA2 is already used for ADC purpose.Thank you very much for any help !

Hello,I am trying to read the value from the INA186A3IDCKR current integrated circuit using the ADC2_INO channel on the stm32f103c8t6 microprocessor. My ADC channel is connected to the Vout section. When I examined the datasheet, I did not come across a formulation, but I want to use the adc value Vout I read in the formulation I will find.Can you help me?(Below is the usage of the integrated circuit)

We have one of our products failing a certification test because the radiated RF energy at 168 MHz is too high. This 168 MHz being the MCU clock frequency. The treshold is only exceeded by 0.8 dB so that's really annoying. We could solve this by placing a metal hood over the MCU but that requires quite a bit of redoing the PCB-layout and it seems a bit of overkill to solve just this 0.8 dB.....  I wonder if there are any other tips and tricks that we could use to bring the clock frequency RF leakage down?(note: we are already using a multilayer PCB of which two layers are groundplanes, so nothing to gain there)

Hi, I'm trying to create my first project with ethernet on STM32H7. I tried to give an example with a nulceo with a similar chip and I succeeded, now I'm moving on to my custom board.I configured the system with STM32CubeIDE, generated the code and just tried to launch the program, what happens is that during initialization, at this point:  /* Dummy read to sync with ETH */ (void)SYSCFG->PMCR; /* Ethernet Software reset */ /* Set the SWR bit: resets all MAC subsystem internal registers and logic */ /* After reset all the registers holds their respective reset values */ SET_BIT(heth->Instance->DMAMR, ETH_DMAMR_SWR); /* Get tick */ tickstart = HAL_GetTick(); /* Wait for software reset */ while (READ_BIT(heth->Instance->DMAMR, ETH_DMAMR_SWR) > 0U) { if (((HAL_GetTick() - tickstart) > ETH_SWRESET_TIMEOUT)) { /* Set Error Code */ heth->ErrorCode = HAL_ETH_ERROR_TIMEOUT; /* Set S

When I configure 8 EDATA sectors withFLASH_OBInitStruct.OptionType = OPTIONBYTE_EDATA;FLASH_OBInitStruct.Banks = FLASH_BANK_1;FLASH_OBInitStruct.EDATASize = 8;HAL_FLASHEx_OBProgram(&FLASH_OBInitStruct); and then I read the result: FLASH_OBInitStruct.Banks = FLASH_BANK_1;HAL_FLASHEx_OBGetConfig(&FLASH_OBInitStruct);The FLASH_OBInitStruct.EDATASize member has the value 3. This is caused by two issues:In CMSIS/Device/stm32h563xx.h (and 562xx, 573xx and 503xx as well)#define FLASH_EDATAR_EDATA_STRT_Msk (0x3UL << FLASH_EDATAR_EDATA_STRT_Pos) /*!< 0x00000003 */while according to the datasheets this field is 3 bits wide:

Hello,I am Currently working on STM32 Low Power Mode and For an Application, I have to Wake Up the Controller from CAN Receive Interrupt. Although In the Datasheet it is mentioned that wakeup is possible using External Interrupt and RTC but I would love to understand, is there any method to Implement Stop Mode and Wakeup using CAN Receive Interrupt. Currently I am using HAL Libraries for the Development.

Hi I am working on multichannel ADC ,if its a single conversion I am getting correct values but when it is more than 1 i am getting same conversion values from all channels. void Adc_Vbat(void) { ADC_ChannelConfTypeDef sConfig = {0}; sConfig.Channel = ADC_CHANNEL_16; sConfig.Rank = ADC_REGULAR_RANK_1; sConfig.SamplingTime = ADC_SAMPLINGTIME_COMMON_1; if (HAL_ADC_ConfigChannel(&hadc1, &sConfig) != HAL_OK) { Error_Handler(); } } void ADC_Mains(void) { ADC_ChannelConfTypeDef sConfig = {0}; sConfig.Channel = ADC_CHANNEL_5; sConfig.Rank = ADC_REGULAR_RANK_1; sConfig.SamplingTime = ADC_SAMPLINGTIME_COMMON_1; if (HAL_ADC_ConfigChannel(&hadc1, &sConfig) != HAL_OK) { Error_Handler(); } } static void MX_ADC1_Init(void) { /* USER CODE BEGIN ADC1_Init 0 */ /* USER CODE END ADC1_Init 0 */ ADC_ChannelConfTypeDef sConfig = {0}; /* USER CODE BEGIN ADC1_Ini

hi there, I want to communicate between two Stm32 using SPI, when i transmit date from master to slave, it received(using received interrupt). but when want to transmit date from slave side it gives HAL_error,master side code while (1) { for(int i=0; i<9;i++) { HAL_GPIO_WritePin(SPI1_NSS_GPIO_Port, SPI1_NSS_Pin, GPIO_PIN_RESET); // HAL_Delay(10); HAL_UART_Transmit (&huart1, "OK1\r\n", 5, 10); data[0] = 0x40 + i; // multibyte write data[1] = 0x60 ; status = HAL_SPI_Transmit (&hspi1, data, 2, 1000); // write data to register // HAL_Delay(10); status = HAL_SPI_Receive (&hspi1, Rxdata, 2, 5000); // write data to register HAL_GPIO_WritePin(SPI1_NSS_GPIO_Port, SPI1_NSS_Pin, GPIO_PIN_SET); if(Rxdata[0] == 0x11) { HAL_UART_Transmit (&huart1, "Received11\r\n", 12, 10); } HAL_Delay(1000); }Slave side code

HiI would like to know about filter behavior in ID list mode and 16bit scale.I would like to receive 3 standard IDs.I know that with the combination of ID list and 16bit scale, I can receive 4 standard IDs. In this case, one will remain when setting in the CAN_FiR1/CAN_FiR2 register. If there is a surplus, the initial value of this CAN_FiR1/CAN_FiR2 register is undefined, so is it better to set it to 0x0000 or to set one of the three IDs that you want to receive? If you set 0x0000, you will be explicitly set to receive ID=0x000, so I am thinking of setting one of the three IDs you want to receive.For ID List (16bit), Filter Num is 0 to 3. With the following settings, CAN ID 0x001 will be set in two locations( 0 or 3).CAN ID 0x001 is Filter Num = 0CAN ID 0x002 is Filter Num = 1CAN ID 0x003 is Filter Num = 2CAN ID 0x001 is Filter Num = 4In this case, is the Filter Num stored in the receivi

RM0481 says: (I am using STM32H563)USB_ISTR.IDN is the endpoint (or channel in host mode) identification number that generated the interrupt request, and if there are more than one endpoint requesting an interrupt, the lowest (CHEP0R) has a higher priority (than CHEP1R etc.). IDN is set by the hardware, thus read-only.USB_CHEPxR.EA is endpoint (or channel in host mode) address. EA is programmed by the software. "x" can be 0..7 since the hardware supports 8 endpoints.Is IDN and EA refer to the same thing (USB endpoint number) ? or is IDN refer to the number "x" in CHEPxR, and CHEPxR.EA is actually the USB endpoint number ? So, for example if CHEP1R.EA=5, and an interrupt with ISTR.IDN=1 arrives, does it mean the interrupt is for an endpoint with endpoint number 5 (i.e. defined in USB descriptor with bEndpointAddress[3:0] = 5) ?

This is a question I posted on Reddit a long time ago, but it hasn't been solved yet, so I'm asking here.I solved the dlc value in the notepad picture.And there was an error even though I connected the rs pin afterwards.I want to know the solution to this error code 2097152.Is there anyone who got the same error as me while using the can protocol?

Hi,When using the STM32CubeMX to configure the ethernet pins for the STM32H573VI, the TXD1 and TX_EN pins can be configured to the PB13 and PB14 pins. But the STM32CubeMX does not allow these pins to be configured for ethernet for the STM32H563VI. In the datasheet of both, PB13 and PB14 cannot be configured for ethernet. I wonder if PB13 and PB14 really cannot be configured for ethernet?

I am trying to send data from a buffer to a GSM module. The buffer contains the AT commands. For each communication this will vary. If i use the Circular mode the transfer will not end. But when i am trying to use the Normal mode so that i can control when to send data I cannot use the  HAL_UART_Transmit_DMA  function. This function only works once. Please Help.

Posted on November 10, 2015 at 15:39Hi, I need to disable a EXTI interrupt and then enabling it again later. How can I do that using the hal implementation? I am working on STM32F070.

hello, I am applying the safety library provided by st company to stm32f103c8.In the example provided, the capture function of TIM5 is connected to the LSI oscillator, but the MCU (stm32f103c8) I use does not seem to be able to connect to the LSI oscillator.I need your advice.

Hi,I have a problem in my program with the CAN SCE Interrupt. I work with a STM32F412VG but I have the same problem with a STM32F413VG, STM32F103C8 and STM32F042K6. And I work with MikroPascal Pro IDE from MikroElektronika.I try to get an interrupt when there is an error in the CAN bus, and to achieve that I try to use the CAN SCE Interrupt.The problem is that the register (CAN_IER) is configured in accordance with the reference manual for the STM32F412VG but the interrupt is never triggered by the CAN1_MSR.ERRI flag. The flag CAN1_MSR.WKUI triggers correctly the interrupt.I monitored the CAN1_MSR register to verify that the bit is really set when there is an error and it is set correctly (tested with an ACK error), the only thing that doesn't work is the trigger of the interrupt.In the configuration procedure, I configure the CAN_IER like that :CAN1_IER.LECIE := 1; //LEC CodeCAN1_IER.BOFIE := 1; //B

My target:I want to use the same uart lines(RX line and TX line) to achieve communication between computers and multiple devices (in other words: multiple slave devices, computer as master). I use some STM32F072C8 as slave devices, and configure these slave devices as follows:configure USART1 to DMA send modeDisable exti interrupt at USART1 TX gpio PA9 or enable the interrupt and add some delay time in the interrupt handle function.Total methord:I use computer to send a message through UART. The slave devices reply the message as soon as receiving the  master message by uart.Avoid slave device

During self flash programming (IAP - InApplicationProgramming) the STM32 reference manual states that a clear BSY1 flag indicates the end of erasing/programming cycle.Carefully examining the HAL library: it uses FLASH_WaitForLastOperation function that contains waiting for both of BSY1 and CFGBSY flags to be clear.Examining the behavior of both flags with scope (flag state copied to a portpin), it shows that both flags works the same.SO, what is the real difference between the two flags, and which one to use to be sure flash erasing/programming done?

There is any possibility to detect exact point on  Rising to Falling or Falling to Rising place .Because when i enabling  Falling edge or Rising/Falling detection in cube ide and same time if  i2c  sensor activated then interrupt signal generated and Interrupt Call Back has been activated two times because LOW level interrupt time (t) .

hello , where can i see cpu cycle count from one breakpoint to next breakpoint in stmcubeide ? i am using stm32f103 board.

My STM32H743 SPI interrupt handler is being repeatedly called even though the interrupt enable register (IER) is 0. I'm running in slave mode and probably doing something really wrong for this to happen. Here are the register values:Name   Value   Access   CR1   0x00000001   ReadWrite       IOLOCK   0   ReadWrite       TCRCI   0   ReadWrite       RCRCI   0   ReadWrite       CRC33_17   0   ReadWrite       SSI   0   ReadWrite       HDDIR   0   ReadWrite

Hello,I am utilizing the FDCAN1 CANbus protocol on the STM32H725AGI6 MCU currently. I am trying to determine the execution time for the firmware to execute the lines of code, as the timing can be critical in some applications.  So for example, I would like to determine how long this line of code takes to execute:HAL_FDCAN_AddMessageToTxFifoQ(&hfdcan1, &TxHeader, &TxData0[0]); The FDCAN is running on a 48 MHz clock currently.  Obviously HAL_GetTick() does not work, since it's in the time frame of milliseconds and the execution would be less than 1ms. So I am looking to get a more accurate time. Does anyone know if this is possible?

Hi all, I was wondering if there is a way to set up the LSE as the source for a Timer on the STM32F030R8 to generate a PWM output signal. Currently doing a deep dive on clock configurations, timers, etc. and I have been able to use the HSE for PWM, but can I use the LSE for PWM? Maybe with RTC?Thank you in advance for answers!

Hi i m using 26 keyboard key to interrupt via UART received, should i coded the 26 interrupt in a single rxcplt callback function or a multiple callback function? Whats the best way? pls advise...void HAL_UART_RxCpltCallback(UART....){  HAL_UART_Receive_IT(huart, &rx_data....)  if (rx_data  == 'a')....  if (rx_data == 'b')...if (rx_data == 'c')}
