STM32 MCUs Products

Hello.. can anyone advise where to download the F767 Nucleo BOM list? 

Does HAL_RTC_AlarmAEventCallback work if the the MCU is in shutdown ?I am using RTC wake-up timer for wake/shutdown cyclingRTC alarm for shutdown trigger via HAL_RTC_AlarmAEventCallbackBut:RTC Alarm A interrupt never fires if the MCU is in Shutdown mode waiting for the RTC Wake-Up timer.For test purposes I am using the following values:Wake cycle set to 10 secondsShutdown cycle set to 5 secondsAlarm set to 28 secondsFrom power up the MCU should run as follows...1. Wake cycle for 10 seconds2. Shutdown cycle for 5 seconds3. Wake cycle for 10 seconds4. Shutdown cycle for 5 seconds..... but after 3 seconds the alarm time is reached (28 seconds). 5. When the alarm occurs.... RTC wake is disabled and WKUP pin wake is enabled, then shutdown is called.6. The MCU must not wake until the WKUP pin is detected

      In my STM32G431CBU6 implementation, COMP1, COMP2 and COMP3 are configured for back-EMF zero-crossing detection with TIM1 CH5 serving as the blanking source. Both rising and falling edge interrupts are enabled on the comparators. TIM1 channels 1, 2 and 3 generate PWM signals for motor MOSFET driving. Despite TIM1 CH5 blanking covering the entire PWM period, the comparator interrupts continue to be erroneously triggered by PWM switching noise  

According to AN5054, to prepare SFI (secure internal firmware install) or SFIx (secure external firmware install) "STM32 Trusted Package Creator" is required. Were do I find it? Searching ST website I find no such software product. Was it maybe recently replaced or "absorbed" by STM32Cube Programmer?

Hi,I originally planned to program my STM32G030K6T6 via USB using the DFU bootloader, but the datasheet doesn’t mention USB_DM/USB_DP, and STM32CubeIDE’s .ioc file shows no USB option under Connectivity, so I believe USB DFU isn’t supported. What’s the best and easiest way to program this MCU, considering future mass production? I’m looking for a reliable, scalable method.Thank you for the assistance!STM32G0 Series Bootloader

Hi,I'm using the Zephyr platform with the STM32U5G9ZJ-DK2 board. I want to put the device into a low-power mode when it's not working. After modifying the DTS file and enabling power management, the device can enter and wake up from Stop3 mode normally. However, according to the datasheet, all IOs are in a floating state in Stop3 mode, but I need to control peripheral devices through some IOs. Is there any way for me to handle these IOs when entering and exiting Stop3, or can I choose to enter only Stop2 mode? Yang,BR

There is an inconsistency in the Reference Manual.The Reference Manual specifies on page 917 that:"Option 2) has the advantage of using the system without additional PLL. In addition, whenadc_sclk is twice faster than the adc_hclk clock, the latency between the trigger and thestart of conversion is fixed. This can be useful when the ADC is triggered by a timer and ifthe application requires that the ADC is precisely triggered without any uncertainty(otherwise, an uncertainty of the trigger instant is added by the resynchronizations betweenthe two clock domains)."At the same time, on page 1036 it says:"In synchronous clock mode, when adc_ker_ck = 2 x adc_hclk, there is no jitter in the delayfrom a timer trigger to the start of a conversion."Since adc_ker_ck is not the same as adc_sclk, and in fact will always be at least twice slower than adc_sclk, which of the

Hi there Is there any stm32 MCU versions that has can run both CAN and USB simultaneously without conflicting with the PB8 boot pin? Also the USB will only be recognized if the PB8 pin is pulled high can i just directly connect it to 3.3v and always keep it on. will that be a problem 

Hi, I am new to the field of ST Microcontrollers and am currently working on developing firmware for a product that utilizes the STM32 Microcontroller, specifically the NUCLEO-H7A3ZI board. We are using the design implemented on this board as a reference for our product. This product will be deployed at remote locations for data collection purposes, among other things. We have a requirement from our customer to frequently update the firmware on these deployed products. The most feasible option we have identified is to distribute the latest firmware on USB pen drives, which local technicians or end-users can then use to perform the update. Could you please explain the necessary steps to accomplish this firmware update process using a USB pen drive? You can explain  the process of firmware upgrade using USB pen drive,  by taking a simple example say :Hello world or a LED blinking program as an example. Once I learn how to do it for simple LED blin

Hello.. I'm designing a project using STM32F767 that upgrades firmware using USB Host 2.0.

Should i use the 4 wire USB female connector? with these pins VCC, D+, D- , Gnd? Please advise soon, thx woldes

Hello everyone, I encountered a problem while using the STM32H750 MCU. The hardware environment is STM32H750 + USB3300, which is used as a USB HOST HS to collect camera data. An LTDC interface is used to connect a TFT-LCD for display. An external SDRAM of 32MB is expanded, with a bus width of 16 bits.  Currently, when both the camera data and the LCD frame buffer are in the internal RAM, the MCU works normally. However, when the LCD frame buffer is placed in the external SDRAM, the USB HOST fails to work properly.

Hi everyone,I'm encountering an issue with the reset cause on my STM32H723VE microcontroller.Whenever I perform either a software or hardware reset, the RCC->RSR register does not retain any value—it always reads as zero.Here’s what I’ve observed using Ozone:If I set a reset breakpoint, execution halts immediately after the reset, as shown in the image below. However, if I set a breakpoint at the first instruction of the Reset_Handler, and then press "Run", execution stops correctl

Hello.I am using STM32F745 to write to FLASH, but the write fails and the ERSERR flag is set.However, this ERSERR flag is*(__IO uint32_t*)0x080C0000 =data; /* (4) */*(__IO uint32_t*)(0x080C0000+4) =data2; /* (4) */If you comment out this part, it will not set.Why does the flag not set during erase operations, which should cause an erase error, but instead set during write operations?By the way, when only FLASH unlock and FLASH erase operations are performed, the selected sector is erased normally.I am seeking a solution to ensure that write operations to FLASH are performed normally.#define FLASH_SR_BSY (1 << 16) #define FLASH_SR_EOP (1 << 0) #define FLASH_CR_LOCK (1 << 31) #define FLASH_CR_SER (1 << 1) #define FLASH_CR_SNB (0x7 << 3) #define FLASH_CR_STRT (1 << 16) #define FLASH_CR_PG (1 << 0) #define FLASH_CR_PSIZE (0x3 << 8)

Hi, I am looking for the offline programmer and adaptor required to program STM32H753VIH6.

Hello all, I want to ask you that is any microcontroller in STM32 series which gives the 5V digital output .. I'm using STM32F746ZGT6, that gives 3.3V as digital output.. I want 5V digital output from microcontroller.. if somebody know then please suggest me .. 

I'm designing a power supply for an STM32H745. I have a 28V source and was planning to implement two buck convertersthe first regulates from 28V to 3.3V and supplies the Vdd railthe second regulates from 3.3V to 1.15V and supplies the Vcore railHowever, this seems to violate the power rail sequencing requirements of the STM32H745. I'm having a little trouble deriving the exact requirements from the datasheet and "Getting Started Guide" (AN4938), but the following excerpt makes me think that if I'm bypassing the internal LDO and driving Vcore externally, the Vcore rail must come up before the Vdd rail: 

Hello... i recently downloaded STM32 example from ST website,  How can i load these example into CubeIDE ?

I am currently evaluating the STM32G0 series for a project that requires two USB Type-C ports.Each port needs to support both Dual Role Port (DRP) functionality and DisplayPort Alternate Mode (DP-Alt).Can the STM32G0 be implemented?

Hi guys, sorry if I'm posting this in the wrong area.I'm starting a project that uses a 1024x768 graphics display and I was wondering which STM32F MCU  (LQFP 176pin) would be the better to drive the RGB Panel. I would be using external memory but if there is a MCU with internal memory that can display 1024x768 that would be easier and would make the project cheaper as well.Can you please let me know as soon as possible as at this stage I'm doing the research on what I need before I purchase all the parts.Thanks guys and hope to hear from you soon.Peter 

Hi @st Team,We had observed some unknown behaviour with respect to flash.MCU => STM32U073CC.Tools => STM32Cube ProgrammerWe need to write this mentioned value @last page of flash @address = 0x0803F800.After doing multiple connect/disconnect, The mentioned value got disappeared abruptly.

Hi.I like to make a little spreadsheet/graphic for MCUs that shows all of the available pins and the functions available on them. You can sort of view it in CubeMX, but not in a table. Makes selecting pins and layouts easier.I do them by hand but it's a chore, especially on MCUs with a lot of peripherals. Is the data available in some form that I can process automatically? There is a table in the reference manual of each part, but it's not easy to convert to something like CSV.Thanks.

HiI'm testing a FMC connection between the mcu on a STM32H753I-EVAL2 board, and a FPGA acting as a SRAM device.Write operations looks OK, but when I try to perform a read operation, it looks like that even thought the nxe and noe behave as expected, the mcu is driving the data bus with random data, not allowing the FPGA to drive desired data.I tried various timing settings, and also changed to PSRAM, in regular and muxed mode, but nothing changed.I also turned on the MPU, with a allow all transactions setting. Can you please point me to what I'm missing here?

I want to check and ensure the option bytes are correct from with my executing program. But writing the option bytes is very flaky if the IWDG is active. For some reason, there is a stall at "FLASH_CR_OBL_LAUNCH". Or maybe it makes it past but not soon after the watch dog resets the MCU and the option bytes are not written. This is an ongoing cycle forever.If I disable the IWDG then things work normally. Any idea why? void CodeProtect() { bool needsUpdate = false; // Unlock FLASH if (READ_BIT(FLASH->CR, FLASH_CR_LOCK) != 0x00U) { /* Authorize the FLASH Registers access */ WRITE_REG(FLASH->KEYR, FLASH_KEY1); WRITE_REG(FLASH->KEYR, FLASH_KEY2); } // Unlock Option Bytes if (READ_BIT(FLASH->CR, FLASH_CR_OPTLOCK) != 0x00U) { /* Authorizes the Option Byte register programming */ WRITE_REG(FLASH->OPTKEYR, FLASH_OPTKEY1); WRITE_REG(FLASH->OPTKEYR, FLASH_OPTKEY2); } // --- C

Hello STM Community,I am currently working with the STM32C031C6 Nucleo board to implement various power reduction techniques, including Sleep, Stop, and Standby modes. At this stage, I am trying to wake the MCU from STOP mode using the RTC wakeup timer without relying on any external triggers such as the user button.While several working examples and tutorials exist for other STM32 families like STM32L4 and STM32F4, I have found that those approaches do not directly apply or work as expected on the STM32C031C6.If anyone has successfully implemented RTC wakeup from STOP mode on this MCU, I would greatly appreciate any guidance, insights, or a minimal working example to help move forward.Thank you in advance for your support!
