STM32 MCUs Products

Hi all,I’m working with an STM32H745 controller and an external ULPI PHY (FUSB2805, pin-compatible with STULPI01A). All hardware connections are verified and correct – the PCB layout and power rails are within spec, and the ULPI lines are as per the datasheets/reference.Problem:If I configure the USB peripheral for HS External PHY and set the speed to 12Mbps (Full Speed), the port is detected and data transfers work using the external PHY. but only when the USB Clock Mux is set to RC48 (internal 48MHz)

Dear friends, I am playing around with NUCLEO-H745ZI-Q.I generated example motor control project from en.X-CUBE-MCSDK-FUL_6.4.0 for CubeIDE v.1.18.1. This example project utilizes CM4 core. Clock frequency for CM7 core can be twice higher than the clock frequency for CM4. Therefore, I believed that CM7 core can run code twice faster than the CM4. I use GPIO Output to measure code execution time on the oscilloscope.To estimate completion time, I use a code in a while() like this: HAL_GPIO_TogglePin(GPIOK, GPIO_PIN_0);Ialphabeta = MCM_Clarke(Iab);HAL_GPIO_TogglePin(GPIOK, GPIO_PIN_0);HAL_Delay(100); I/O pin is in “Very High Speed Mode”. So, running it on CM4 @240 MHz, I get:

Hi all,I'm designing STM32N655L0 based board and I've one question.I'm using XSPI1 and XSPI 2 peripherals.XSPI2->Octa SPI mode, NOR FlashXSPI1-> SDRAM, Hexa SPISo my question is can I use unused CS, NCLK pins as an IO?I just wanted to be sure. BR

Hi,I want to increase the amount of RAM for my application, but I noticed that the NPU seems to be using memory from address 0x34100000 (SRAM2) in the sample application it is based on. Where can I change this? Are there any limitations to the memory that can be used? BR,Artur 

Hello,the following code is generated by CubeMX 6.11.1 in module stm32l4xx_it.c:/** * @brief This function handles TIM1 trigger and commutation interrupts and TIM17 global interrupt. */ void TIM1_TRG_COM_TIM17_IRQHandler(void) { /* USER CODE BEGIN TIM1_TRG_COM_TIM17_IRQn 0 */ /* USER CODE END TIM1_TRG_COM_TIM17_IRQn 0 */ HAL_TIM_IRQHandler(&htim1); HAL_TIM_IRQHandler(&htim17); /* USER CODE BEGIN TIM1_TRG_COM_TIM17_IRQn 1 */ /* USER CODE END TIM1_TRG_COM_TIM17_IRQn 1 */ } /** * @brief This function handles TIM1 capture compare interrupt. */ void TIM1_CC_IRQHandler(void) { /* USER CODE BEGIN TIM1_CC_IRQn 0 */ /* USER CODE END TIM1_CC_IRQn 0 */ HAL_TIM_IRQHandler(&htim1); /* USER CODE BEGIN TIM1_CC_IRQn 1 */ /* USER CODE END TIM1_CC_IRQn 1 */ }Interrupts for TIM1 (capture) and TIM17 (global) are both activated, but with different priorities.The problem is that TIM1_TRG_COM_TI

Hello,I was looking into this wiki tutorial on setting up a UDP echo server by @mƎALLEm , and the clock configuration caught my eye and wanted to confirm a few things.On the nucleo board , the 8 MHz crystal (X3) is not soldered and the 8 MHz clock signal comes directly from the ST-Link MCU (U2) via SB149. I have checked this on a oscilloscope. But in the tutorial , in Section 2.1 Clock configuration Section , the screenshot shows the input frequency set to 16 MHz. As far i am aware this should be 8 , not 16 MHz. Can someone please confirm this?

I am using a STM32H723ZGT6. I am trying to Trigger an Input Capture on TIM1 Channel 1 by connecting to the output of the Comparator internally,but cannot get the TIM1 Configuration to fire the Input Capture Callback. I've turned on the input capture interrupt function and comparator. HAL_COMP_Start(&hcomp1);   __HAL_TIM_SET_PRESCALER(&htim1, 275-1);   HAL_TIM_IC_Start_IT(&htim1, TIM_CHANNEL_1);   HAL_TIM_IC_Start_IT(&htim1, TIM_CHANNEL_2);

Hello,I have an STM32F429 project with a 1PPS input (PA0) and a 10Mhz oscillator (PB3) a PWM output (PA1), I can't get a value in my Timer2 it's always at 0, I don't see where my mistake is, can someone help me?Attached file (.zip)Thanks you all.Sébastien.

Hi All, In datasheet of STM32N657X0H3Q controller only power-up sequencing details are shown., Is there any power down sequencing is required?If Yes, Please suggest the document which gives complete information of power down sequencing. 

I designed a custom board using the STM32H725ZGT3. The references I followed include the datasheet, application note AN5419, and the STM32H745ZIT6 Nucleo board design, among others. After powering up the board, I was able to connect to it via ST-Link using STM32CubeProgrammer, and successfully uploaded a simple blink code using STM32CubeIDE. The code worked, and the LED started blinking. However, after a power cycle (i.e., turning the main power off and on again), the board stopped running the code, and the LED no longer blinked. I tried reconnecting with STM32CubeProgrammer, but I received a "Target not found" error. After that, I connected the BOOT pin to 3.3V. This allowed me to connect to the board again using STM32CubeProgrammer, but I couldn’t upload code using STM32CubeIDE. I then changed a setting in the CubeIDE: System Core → RCC → Parameter Settings → Power Parameters → PWR_LDO_SUPPLY 

Hi, I am working on a project and having the following problem:My UART DMA is not working. I am transmitting a string, that should be visible in the terminal but it is not. The TX complete callback function is being triggered, so it looks like it works but there is nothing in the terminal. Previously, I was using UART without DMA and things were working fine. It confirms that the hardware connections and the VCP connections are correctly set up.   What I have done so far: - I enabled UART2, tested UART (without DMA). It worked well. - I enabled DMA which gave me:   - Then I set up GPDMA1

I am trying to get the RTC alarm working whilst also using a periodic wake, I can get each working independently but not both together.If I DON'T shutdown for RTC wakeup, the RTC alarm DOES work.If I DO shutdown for RTC wakeup, the RTC alarm DOES NOT work.To summarize:I am trying to use RTC Alarm for a shutdown in 1 minuteBut I've also configured an RTC Wakeup Timer to wake every 5 secondsAfter shutdown, RTC Wakeup Timer works — but RTC Alarm doesn'tWhen I re-call MX_RTC_Init(), the Alarm is lostBelow is the function I call to shutdown the mcu for 5 seconds, before waking up again...void shutdownRun (void){ /* The Following Wakeup sequence is highly recommended prior to each Standby mode entry mainly when using more than one wakeup source this is to not miss any wakeup event. - Disable all used wakeup sources, - Clear all related wakeup flags, - Re-enab

Hi,I am working on STM32G474CET mcu. I am trying to use VREFBUFF voltage for ADC channel referance voltage. My configuration looks like the following. When i run the code, it stuck in the HAL_SYSCFG_EnableVREFBUF function. Whenever i check the 'tickstart'  variable it remains 0.  /** * @brief Enable the Internal Voltage Reference buffer (VREFBUF). * @retval HAL_OK/HAL_TIMEOUT */ HAL_StatusTypeDef HAL_SYSCFG_EnableVREFBUF(void) { uint32_t tickstart; SET_BIT(VREFBUF->CSR, VREFBUF_CSR_ENVR); /* Get Start Tick*/ tickstart = HAL_GetTick(); /* Wait for VRR bit */ while

Hello All,I got Classic CAN running on the FDCAN3 module of STM32G474CE device using MXCube and other example projects for STM32G474 devices.Problem is, all these example codes have a fixed baud rate of 1Mbps. My application requires thebaud rate be configurable. Until now, I have not been able to find any table / calculator on the internet that could calculate the bit timing register values for me, based on kernel clock and required baud rate etc... Does anyone here have any clue on this?

Hi ST Community, I am currently trying to evaluate if I can use EXTI GPIO IRQ handlers (function executed at USER BUTTON press) in combination with the STOP3 sleep mode.Firstly, I would like to request, if this is supported by the u5 CPU. Based on the reference manual, only a WKUP interrupt can wake up the CPU from STOP3 mode. So is the following scenario realizable?1) CPU configures EXTI GPIO (USER BUTTON) with IRQ handler/function2) CPU goes into STOP33) User presses USER BUTTON4) CPU leaks STOP3 (WKUP interrupt)5) CPU executes EXIT GPIO IRQ after wake up6) CPU goes pack to STOP3 and waits for next wake up7) <infinite loop from 2.> Or are the WKUP and EXTI GPIO interrupts exclusive? (only one can occur).---Unfortunately, it seems that this sample is not covered by the cube IDE samples.Or have I overlooked one? So I have looked at the samp

Hi EveryOne,                  I have made a custom board with STM32H7B0 and  W25Q128 . where W25Q128 has to hold the user application . I hoped that i can change OSPI in STM32H7B0  to a QSPI config and work with W25Q128  ( which will only work with SPI or Qspi) . I can't able to select QSPI config ( which is mentioned as it is already activated ) in Octal SPI parameters . i'm using  firmware version :FW H7 1.12.1   since this is a personal one i can't change the  W25Q128 to another OSPI supported flash memory  IC. Is there any example or any othe

Hi everyone,I am working on a project where I need to interface an external ULPI PHY (FUSB2805) with the STM32H745 for high-speed USB communication using USB CDC. This is my first time working with an external USB PHY, and I am facing some difficulties.My setup:MCU: STM32H745External PHY: FUSB2805 (connected via ULPI) with Type-C USB connectorIDE: STM32CubeIDEWhat I have done so far:In STM32CubeMX, I have selected the USB HS mode and configured it as CDC class.Under USB HS settings, I have selected external PHY.I followed the hardware design guidelines, and my schematic for connecting FUSB2805 to the STM32H745 as datasheet guidelines.The USB connection results in a "Unknown device: Descriptor request failed" message when connecting to a PC.Issues:--> The USB device is not recognized by the host (shows an error message: "Unknown device: Descriptor request

I have a custom board with an STM32H730 and a LAN8710A PHY, operated in RMII mode.  The board is a new design, based on an older board but with some differences (the older board has an STM32H750).  My short-term goal is to prove out the hardware -- a response to a ping would be sufficient for this.I have no prior experience with the STM32 family.  I set up a project with STM32CubeIDE, following the Ethernet video from ControllersTech.  I'm at a point where the firmware initializes without error, and seems to correctly set up the PHY.  But then I run into problems.With the board plugged into the building LAN and a scope connected to the RX lines of the PHY, I see activity on those signals.  There is, however, no activity on the TX lines going from the processor back to the PHY.  And of course there's no response to a ping.We're outputting a 50 MHz clock from MCO1, and feeding that into ETH_RMII_REF_CLK and into the PHY cloc

 

Hi,I'm working on an STM32G491RE-based project where we need to configure 10 GPIO input pins as external interrupts. Each of these pins is on a different port and mapped to a unique EXTI line (EXTI0 to EXTI10), so there’s no conflict in EXTI line usage.Due to current hardware limitations, we're unable to physically test all these pins simultaneously. However, I’d like to know: is it valid and supported to configure and enable all 10 EXTI lines in the firmware?Thanks in advance!

Hi Mr/Mrs,I have one problem about flash software for Stm32F103C8T6. When I compile and flash software for the first time, everything is OK. But, I have changed code and compile successfully then software can not flash to board. I see that there is one different point about SWDIO. At second time, it is “No target device”. I have tried switch Boot 0 into 1 and software flash success. I also tried with new target board and issue is similar. Here, I have used ST-Link V2 mini for Stm8, Stm32 and target board Stm32f103c8t6 via Keil C IDE.Could you please help me check and give for me some tips to resolve this problem? Thanks so much!

Am I seeing this right? According to the datasheet, the STM32F413xG/H only maps USART3_RX to PB11, PC5, PC11, and PD9. All four happen to not exist in the STM32F413CG/H variants with the UFQFPN48 package!Bit weird this doesn't seem to be noted anywhere. I guess this 10 UART chip is really a 9.5 (or fewer?) UART chip in the 48 pin package? Extra keywords: STM32F413C STM32F413CH

Hello  hope some one can shed some light please,I have a STM32F446RE board with SPI1 setup for 8pin SPI FRAM memoryI have written my own firmware using DMA / SPI1 to read and write to this FRAM ICThis is a very fast no volatile memory IC that does not have the limitations of standard FLASH memoryReading and Writing continuously SPI1 40MHz speedIt does not require or use Block / Page / Sector , polling, time delays for write etc.Its just continually allows write at very high speed, so eliminates all the pain of poor endurance, latency of normal serial flash memory. Can I find an external flash loader routine for this type of memory so I can use STcube programmer to load the FRAM with my custom data, of course not ???? Could someone please advise in very basic steps how to create a flash loader for my ST32446 I have tried looking at various flash files / github et

Hallo,for security reason I have to stop HRTIM generating 3-phase signal for PMSM motor.It works as described in RM0433 (37.3.23) with DBG_HRTIM_STOP = 1: when debugger stops MCU predefined "FaultLevel" appears on outputs as expected. HRTIM goes into STOP mode. So far very good but... The problem is: "This is permanently maintained even if the MCU exits the halt mode."How can I leave FAULT state of HRTIM on leaving debugger halt without writting debugger script?

Hi,I have an stm32G0B1 that i'm working on. I want to use a timer "TIMER2" but the block diagram of the board doesn't not give the AP2B2 clock bus. I know with other boards is usually mentioned. Where do I go to look for it, as I have looked and I struggle to find it.
