Hi,I want to know by when STMicrolectronics is going to support STM32U0 series in STMCubeMX.-Sumit

Hey, I have a problem with the callback for FDCAN1. I am sending frames through ucandevices converter but the callback for FIFO0 is not called. The frames are definitely arriving, I added a test FreeRTOS and a task to receive and send frames to CAN1 and it worked very well, frames were received and sent back to the bus.I have NVIC interrupts set up, I fiddled with the clock for CANFD and speeds, also with no effect.Is anyone able to help me?I am sending my project as an attachment

Hello,I am currently Using STM32F779NIH6 for one of our application prototypes. Currently the internal RAM size is 512KB and based on our evaluation, for certain peripherals we need a higher RAM size ( Atleast 2X or 3X). Can you suggest any Controller from the High performance MCU family which can satisfy this higher internal RAM requirement but at the same in pin to pin compatible ? Thanks,Siddharth

Hi everyoneI'm currently using the NUCLEO-F429ZI development board. I'm planning to create a PCB using the STM32F429ZIT6, but I've encountered some questions during the planning stage.According to the datasheet, HSE_OSC is specified to provide 8MHz, and CubeIDE also indicates "Input Freq HSE = 8MHz." However, on the NUCLEO-F429ZI development board, the JFVNY 25.000 oscillator supplies 25MHz. I have verified that the SPI clock indeed derives from multiplying and dividing an 8MHz source, but when I measure the JFVNY 25.000 oscillator on the development board, it does indeed supply 25MHz. Why are these two frequencies inconsistent, or am I misunderstanding something?Referring to the Clock tree and considering, if not using the RTC section, is it possible to omit providing the external LSE_OSE?

Hello, I want to use X CUBE USB AUDIO examples in X CUBE IDE.After generating the binary code (without errors) and flashing the binary code via DFU, the card is not recognized as an audio device, I tried on all 4 projects. I unplugged USB, do reset, nothink change.On the other hand, if I generate for example the binary of another audio project: FP-AUD-SMARTMIC1, and flash it via DFU, the card is recognized as an audio device. Thanks by advance.

Hi,I have my master and slave applications running on NUCLEO-H563ZI Boards both of which normally receive/transmit  10 bytes of data in each SPI transfer. I use SPI in DMA mode.However, in one test case, master starts a SPI transaction for only 4 bytes i.e it calls HAL_SPI_TransmitReceive_DMA with Size as 4. So, my master sends clock for only 4 bytes even though the slave has 10 bytes of data. At this point, the Master receives 4 bytes but the HAL_SPI_TxRxCpltCallback on Slave is not called.I am doing a GPIO Pin toggle in the callback to denote completion of the SPI transfer which is necessary for my slave application. How do I abort the SPI communication in this scenario?I see there's a HAL_SPI_Abort_IT. Not sure how to use it. Appreciate if you would provide some insight on this.

Hi, guys, anyone has met such an issue?I was trying to generate code by CubeMX, and I also wanna generate USART1 IRQ handler but failed.here are my settings, anyone can help me with this?thanks 

Hello,I purchased a soldering crystal for X3 according to the BOM list,but it seems that the X4 on the board is the same product.Where is the X4 used?I checked UM2407 User Manual and STM32H742xI/G, STM32H743xI/G datasheets,but couldn't find it. Plus, Is it correct that the MCO (default) from STLINK-V3E uses the X1 source? Thank you.

Hi,I am trying to use the FSM of the ISM330DHCX to check multiple decision tree outputs from the MLC.I want to be able to change the Decision Tree value in the CHKDT condition within the program flow, as I want to be checking multiple decision trees and outputs in the same FSM.From the documentation, I understand that to do this, I need to use the SETP command to change the value of the DECTREE Byte. However, I cannot seem to find the right configuration for the SETP command to be able to change the expected Dec. Tree value.Could you please point me in the right direction?Specifically, what State Machine Address should I be selecting, and what value should I be writing to it, to change the Decision Tree and Decision Tree result in the CHKDT condition? Thanks in advance.

Hi, I'm using  multi channels ADC3 of "STM32H735ZGT6" (3channels) I want to use these channels in parallel, but I've only found a way to convert in order in the Datasheet. Can I run all the ADC3's channels at once in parallel?If that is the case, can I get a reference manual or some advice?If you want to see my CUBEMX or Code, Please tell me. Thank you.

hello everyone i am using stm32h7 MCU, i want averaged ADC data using  hardware over sampling. how can get this.

I am struggling to get USB CDC working. I am very far down a rabbit hole and I'm completely stuck.I am using HAL libraries for USB_OTG_HS on the STM32F746ZGT6, with a 16MHz HSE.I am running in bus powered mode, VBUS detect disabled, and I have hardwired an external D+ pullup, because I have not been able to get the internal pullup to activate. I know the hardwired pullup is not recommended, but I don't think that is what is causing my problems. My IOC file is attached. When I connect the device to my computer, windows reports "device descriptor request failed" in device manager. I have determined the following sequence of events is occurring:1. Connect STM32 to computer (powers on STM32)2. USB suspend interrupt (USBSUSP)3. USB wakeup interrupt (WKUPINT)4. USB reset interrupt (USBRST)5. Enumeration done interrupt (ENUMDNE)6. RX fill level interrupt (RXFLVL), packet status == STS_SETUP_UPDT7. RX fill level interrupt (RXFLVL), packet status == STS_SETUP_UPDT8. RX fill level interrupt

Hello! Recently I got into STM programming for my internship and I cannot figure out register level programming yet, I have this piece of code ```RCC->AHB1ENR |= RCC_AHB1ENR_GPIOAEN | RCC_APB1ENR_TIM2EN;GPIOA->MODER |=GPIO_MODER_MODE5_1 | GPIO_MODER_MODE5_0;TIM2->CCER|=TIM_CCER_CC1E;TIM2->CR1 |=TIM_CR1_ARPE;TIM2->CCMR1 |=TIM_CCMR1_OC1M_1|TIM_CCMR1_OC1M_1|TIM_CCMR1_OC1M_0|TIM_CCMR1_OC1PE;TIM2->PSC=42; //trivialTIM2->ARR=1000; //trivial valuesTIM2->CCR1=250; //trivialTIM2->EGR |=TIM_EGR_UG;TIM2->CR1 |=TIM_CR1_CEN;/* USER CODE END 2 *//* Infinite loop *//* USER CODE BEGIN WHILE */while (1){/* USER CODE END WHILE *//* USER CODE BEGIN 3 */}/* USER CODE END 3 */}```Which in theory, to me, looks like it should work, however there are things I still do not fully understand, for example: Here I wanted to use Tim2 on channel 1 because I can use that on my PA5 pin which is LED2 on my Nucleo f401RE board, and I wanted to produce a PWM signal on it, however, it ju

Hello,I am experiencing the following problem. When I setup an ADC with DMA for 5 channels, occasionally I get lower readings than the expected ones. It also happens in some of our hardware of our production, but others perform ok. We have inspected the components and everything seems identical. We have measured the reference voltage and all the expected voltages on ADC input pins (some are fixed and known) and all looking good too. On the other hand, when I sample only one ADC channel in polling mode, I do not get this problem, the voltages read as expected.Here is the ADC configuration with DMA (source code attached too): 

We use ITM, locally configured by the embedded code at startup, for our trace output.  We have code for this that works with STM32F4 (see below), as advised by Segger; this advice doesn't seem to have changed since we adopted it. Using the same code with STM32U5 we end up in a hard fault after a few calls to ITM_SendChar().  What do we need to add to this code for the STM32U5 case?  I have seen a post on this topic here but that person did not succeed, hence asking this narrower question.Working ITM set-up code for STM32F4 (where U_CFG_HW_SWO_CLOCK_HZ is 125000 to guarantee reliability):uint32_t stimulusRegs;// Enable access to SWO registersDEMCR |= (1 << 24);ITM_LSR = 0xC5ACCE55;// Initially disable ITM and stimulus port// To make sure that nothing is transferred via SWO// when changing the SWO prescaler etc.stimulusRegs = ITM_ENA;stimulusRegs &= ~(1 << 0); // Disable stimulus port 0ITM_ENA = stimulusRegs;ITM_TCR = 0; // Disable ITM// Initialize SWO

Hello  I have been using an STLink v3 pod successfully for several months but suddenly it stopped working.  The green light is lit and the red one flashes slowly.  I cannot see it in Device Manager and there are no Unknown Devices.  There is no chime when I plug it in.  I also don't see the Virtual Com Port in Device Manager or the drive in My Computer that usually comes up.   Cube IDE reports "No ST-LINK detected!  Please connect ST-LINK and restart the debug session" Windows does not report any malfunctions or driver failures. I tried  the following things and all of them get the same blinking lights.--rebooting my machine  (Windows 10)--upgrading CubeIDE 1.15.0-- running installer for ST Link driver: https://www.st.com/en/development-tools/stsw-link009.html-- upgrading LibUSB: https://community.st.com/t5/stm32-mcus-boards-and-hardware/no-st-link-detected-only-in-cubeide/m-p/220718--different cable and usb port  (p

Hi community,I wrote the following functionUINT PrintOut(const char* format, ...) { va_list args; va_start(args, format); char buffer[1024] = { 0 }; vsprintf(buffer, format, args); va_end(args); return PrintString(buffer); }No problems at compiling time, but at runtime the execution falls in HardFault.Any suggestion?

Hi everybody,I am using STM32F042G6 MCU for an automotive project and since It doesn't have mush FLASH (32kB) I am trying to reduce code size as much as possible.Lookign at the linker file generated by STM32CubeMX, I see that instructions are aligned to 4 bytes. Since M0 architecture uses Thumb instruction set which is 16 bit wide, I was wondering wether instructions can be aligned to 2 bytes, saving some flash. Since I am not very experienced in this area of MCU I would like to know from you if this is correct or if I am missing something. I will link part of the linker script. I definitely understand why isr_vector is aligned to 4 bytes but I quite don't why .text is.Thank you in advence!  SECTIONS{/* The startup code into "FLASH" Rom type memory */.isr_vector :{. = ALIGN(4);KEEP(*(.isr_vector)) /* Startup code */. = ALIGN(4);} >FLASH /* The program code and other data into "FLASH" Rom type memory */.text :{. = ALIGN(4);*(.text) /* .text sections (code) */*(.text*)

Is there a way to reset the counter and the prescaler via a hard event or something when an input capture happens?I use timer 1 to have a hall interface and to drive timer 8. But there are some fluctuations, because the interrupt (where i reset counter and prescaler) is not fired at the exact time as the input capture happens.

Hi,I am trying to calculate the MTBF (mean time between failures) value for the ASM330LHHTR module. Please suggest any techniques for the same. I am currently using the Qjc (Junction to Case Thermal Resistance) and Pd (Power Dissipation) values to calculate the same.Please provide the Qjc value for ASM330LHHTR at 35 degrees Celsius or suggest another appropriate method to calculate the MTBF value for the same. Thanks,OF
