STM32 MCUs Products

Hi,I want to migrate a project that I have made on a STM32L4 where I make the spectral analysis of the noise that I read from a digital MEMS microphone using the arm_fft dsp functions to a new board with a STM32U5 mcu.I have tried to include the "libarm_cortex_Mxx_math.a" library to my new project with the STM32U5  but I cannot find it. Is this library available for the U5 microcontroller family ? I am running  "STM32Cube_FW_U5_V1.4.0" firmware package, but under the STM32Cube_FW_U5_V1.4.0\Drivers\CMSIS\DSP I cannot find the folder "Lib" where the compiled arm library for dsp function is usually located.Where can I find the library for the cortexM33  of my STM32U5  in order to run dsp signal processing functions?Has the use of this library changed for this new mcu family ? If yes how can I include and make compile th

Hi, I am new about dual core mcu. I have stm32h745 mcu.  I am working about inter core comminication, Firstly setting some setting on CubeMx. When I create project codes, CubeMx creat 2 openamp library for each mcu(m4/m7). After that I am trying build, and getting error like this.  Error: L6200E: Symbol OPENAMP_init_ept multiply defined (by openamp_1.o and openamp.o).  16 times geting similar error like this.  Why CubeMx create wrong library.  CubeIde working properly. (create only 1 library set)

During porting by code from STM32F3 to STM32H7 i had the problem, that the calculated crc of my firmware was not computed correctly.I found out, that on STM32H7 the reflection of the crc peripheral works not correctly if writing data smaller then 4 bytes into the data register of the crc unit.So in my example, i write a single byte into data register. To get the correct result on STM32H7, i have to reconfigure the reflection to byte-wise instead of word-wise reflection like on STM32F3.// result is wrong on STM32H7 and correct with STM32F3 hcrc->Instance->CR = CRC_CR_REV_OUT | CRC_CR_REV_IN_0 | CRC_CR_REV_IN_1; hcrc->Instance->CR |= CRC_CR_RESET; *(__IO uint8_t *)(__IO void *)(&hcrc->Instance->DR) = (uint8_t)data;   // if configure input reflection byte-wise on STM32H7, then the result is equal to STM32F3 hcrc->Instance->CR = CRC_CR_REV_OUT | CRC_CR_REV_IN_0 ; hcrc->Instance->CR |= CRC_CR_RESET; *(__IO uint8_t

Hey all,I am facing problem in configuring my board in I2c protocol. When  i configured the same board in standard mode it is working fine. Rest of the settings for pins(pull-up) ,rise time and fall time are same in both the files. Also attaching waveforms for both the mode. Can anyone suggest me what can be done to make the board work in fast mode as well.Thanking you in advance.

When I configured development board's I2C I am receiving a short high pulse at 8th clock of SCL.I am attaching the waveform on scope following this post.Thanking in advance.

Hello, I have a problem currently, I am a beginner on stm32 and I would like to create a pulse counter but I cannot get the interrupts from my timer 3 to increment my variable. I don't understand then that the function is indeed carried out but it is not called.And my second problem is i want to count with a TIM to 90kHz and i don't now if it's possible to realise with a stm32f103c8t6. thanks, have a good day 

Hi All - Not sure if this is the right place to ask this, but thought I would try anyway.I just finished a project that used Avalonia UI (C# based cross platform system for application GUIs) on a raspberry-pi 4 with a Waveshare touch screen attached.  It worked very well. :)  It now looks like I'll be starting on another project that needs a UI too but runs on an STM32 MCU based system.  Has anyone tried Avalonia UI on their system?  Did it even work?Curious if there are others who have done this before I start down this path.Thanks!

I encountered a problem while desperately trying to make USB OTG_HS Host configured on a new Nucleo-U5A5ZJ-Q using CubeMX and ThreadX+USBX. I know that this board is not designed to provide USB power, but this can be overcome with undocumented SB8-10 jumpers and UCPD is not an issue here. I am also aware that at the beginning of the HAL_HCD_MspInit() function __HAL_RCC_SYSCFG_CLK_ENABLE(); line needs to be added.After several evenings of research (see here) I think I nailed down the problem to USB_HostInit() function.At the end of this function, host mode events are enabled using GINTMSK register (RM0456, section 73.14.8 OTG interrupt mask register [alternate] (OTG_GINTMSK), offset 0x18).  

HelloI'm using NUCLEO-H503 to make an I3C master, and I have some issues.1. I sent the ENTDAA command for I3C communication, but it does not go to HAL_I3C_STATE_READY.The code written after several attempts is as follows.HAL_I3C_Ctrl_DynAddrAssign(&hi3c1, &payload, I3C_RSTDAA_THEN_ENTDAA, timeout);HAL_I3C_Ctrl_SetDynAddr(&hi3c1, DynAddr);hi3c1.State = HAL_I3C_STATE_READY;Is this a normal way to use the Library?2. Please tell me how to read and write data on I3C slab.For I2C, HAL_I2C_Master_Transmit and HAL_I2C_Master_Receive were used to communicate with the slave device.Is there a function like this for I3C?The function I found is HAL_I3C_Ctrl_Transmit, but do not work in my board.Please let me know the functions you use f

Hey, I have a U599 and would like to use the PA11 pin as an input with a pull-up. I've set the CR1_FORCE_USBPWR, USBPWREN, and VDD11USBDIS bits. However, the pull-up voltage only reaches 1.21V in this configuration. The pin works fine as an output.   /* USER CODE BEGIN SysInit */ SET_BIT(PWR->CR1 , PWR_CR1_FORCE_USBPWR); SET_BIT(PWR->VOSR , PWR_VOSR_USBPWREN); SET_BIT(PWR->VOSR , PWR_VOSR_VDD11USBDIS); /* USER CODE END SysInit */ /* Initialize all configured peripherals */ MX_GPIO_Init(); . .  

Hello,Would you please suggest us alternate microcontroller for which should be the advance version of STM32G431RBT6 and operating voltage should be more than 105 Celsius.best regards,Nisha Yadav @Peter BENSCH

I'm trying, unsuccessfully, to get a simplest single-channel single-ended polling-the-ADC example going on the nucleo h723 eval board.At first I started bare-metal in assembler from the datasheet, but couldn't get the second ADC sample to fire no matter what register gymnastics I did (the first ADSTART puts some bits in the DR, I figure that did something to the analog input).Then, figuring I'm still not setting up clocks right or something, I reverted to STM32CubeIDE and followed various HAL tutorials such as this one; same outcome.https://www.youtube.com/watch?v=6uiO68pdjZAThis particular ADC seems more involved than the simple ones usually covered in tutorials. Can anyone point me to an example of repeated single-shot acquisition with polling or interrupts that actually works on the 723ZGT6 part?(Bonus points if it can actually run at the

Using an Advanced Timer (Timer 1 in STM32H743ZI) in PWM One-Shot mode, and using the Repetition Counter, I generate a string of 5 pulses. For each pulse, I generate a Capture/Compare Interrupt and have a CallBack routine (using "HAL_TIM_PulseFinishedCallBack(...)". This works fine.I have also enabled the Update Interrupt for Timer 1 and expected it to service that routine at the completion of the 5 pulses as well but it does not. The code for the Interrupt is generated in the stm32h7xx_it.c file "(void TIM1_UP_IRQHandler(void))" but execution does not appear to reach it. Both Timer 1 Capture/Compare and Update Interrupts are enabled in the NVIC. I am using "void HAL_TIM_Period_ElapsedCallback(...)" as the call back routine for the Update Interrupt.How do I get the Update Interrupt to work?

As I'm having problems passing images in private messages I'm posting my schematic for an STM32F765 to Ethernet Phy here. 

Hi all,I am using the SAI peripheral on the STM32H753 and I have it set-up as follows:SAI2A - Master TX, asynchronousSAI2B - Slave RX, synchronous with sub-block ASAI3A - Slave TX, synchronous with SAI2SAI3B - Slave RX, synchronous with SAI2(SAI2 SYNCOUT has been set to SAI_SYNCEXT_OUTBLOCKA_ENABLE) Audio from SAI2A is clean.Audio from all other SAI sub-blocks has glitches as shown below.Audio 1 - Source signalAudio 2 - Output from SAI2BI am using the simplified initialization mode using HAL_SAI_InitProtocol() with number of slots set to 2 and data size at 32 bits.I am startin

In the STM32H7 ref manual (RM0433 - Section 51.4.4), the following is said about configuring an SAI block in synchronous mode with the other SAI block in the same SAI peripheralI'm confused about the following statements:Typically, the audio block in synchronous mode can be used to configure the SAI in full duplex modeWhat is meant by full duplex mode above?One of the two audio blocks can be configured as a master and the other as slaveORBoth as slaves with one asynchronous block (corresponding SYNCEN[1:0] bits set to 00 in SAI_xCR1)and one synchronous block (corresponding SYNC

Hi,When I set the clock source of SYSCLK to HSI, I can get the 1 ms timer from TIM2. However, when I set the source of SYSCLK to PLLCLK, I can't get 1 ms timer from TIM2. Why? (The MCU is STM32F407VETx) I would appreciate any help. *Edit : The problem was solved.

Hi,I want to put the USB bus into SUSPEND/RESUME state, currently I'm using gState in USBH_HandleTypeDef to manually put the device into HOST_SUSPENDED state and similarly to move to the Idle state I'm manually assigning gState to be HOST_IDLE.With this approach I'm able to move to suspend state, I have verified the same on oscilloscope, there is no bus activity in SUSPEND stateIssue with this approch is if we move from suspend to ideal state and back to suspend state we can't go to ideal state and we are stuck in the suspend state, I have called MX_USB_HOST_INIT() before making USB state=idle but its stuck in some state or its not getting enumerated againCan anyone suggest any other way or why this is happening? Thanks

Hello,Currently I'm playing around with the I3C peripheral and I try to implement a sort of "eeprom" interface on a I3C target where I have 10 slots which I want to be able to address separately.So on the controller side I have this function:  int i3cc_target_read(int slot_id, uint8_t *buffer) { static uint8_t tx_buffer[I3C_SLOT_ADDRESS_LENGTH]; static uint8_t rx_buffer[I3C_SLOT_DATA_LENGTH_LENGTH + I3C_SLOT_BUFFER_LENGTH]; if (slot_id < 0 || slot_id >= I3C_SLOT_COUNT) return -1; if (_state != I3CS_IDLE) return -2; // prepare the tx frame buffer tx_buffer[I3C_SLOT_ADDRESS_OFFSET] = slot_id; // build the I3C transaction uint32_t ctrl_buffer[16]; I3C_PrivateTypeDef private_messages[2] = { { .TargetAddr = _targets[0].dynamic_address, .TxBuf = { tx_buffer, sizeof(tx_buffer) }, .RxBuf = { NULL, 0 }, .Direction = HAL_I3C_DIRECTION_WRITE }, { .TargetAddr = _targets[0].dyna

To Andrew, SofLi Hy Andrew and SofLi. I well received your last informations posted this week-end. Therefore it was week-end. I test a NUCLEO board without ST-link; my computer is a Mac-mini and the NUCLEO board offers capabilities to be separate in to part, the ST-link microcontroller and the targeted microcontroller, enabling to reduce power consumption on plant. Bootloader offer capability to read and write any address in address space; then I think the simply way to give you understable informations it's to give you an excell file with the list of my search. Hoping this is nice to you, I hope an answer. Best regards. Butterfly.  

"Hello, I'm currently working with the FDCAN module on the STM32H747I-DISCO board. I've successfully configured both FDCAN modules in the M7 core, and they are working as expected. However, when attempting to configure them in the M4 core independently, I encounter issues – the FDCAN modules do not work reliably. Interestingly, if I first call the Init and Start functions for both FDCAN modules in the M7 core, then the modules in the M4 core start working. Nevertheless, this behavior is inconsistent. Can anyone provide insights into what might be causing this issue ? Thank you!"

I'm trying to program STM32WBR55VGY microcontroller in my custom board.Recently, I succeed to debug my microcontroller but after one time, I can see this message on the STM32cubeIDE during debugging and the microcontroller does not work properly."Break at address "0x1fff5e8c" with no debug information available, or outside of program code. error."How can I solve this problem?

I received a recommendation for the U5 series for its low power consumption for medical patient monitors. As a beginner, my experience is limited to the F446RE and H743 Nucleo boards. I chose the STM32F769-DISC0 for its ease of use and integrated display, primarily for testing purposes. My initial goal is to display ECG waveforms(ads1298 module) and eventually integrate a thermal printer(fijistu 8inch). I'm seeking guidance on whether this board can support these functions, including connecting to an external 1280x720 display and handling touchgfx or 1080p is limited means can it be easily handle 10' 1080p display of mipi dsi and able to print ecg waveform . Also, is it feasible to use external memory with this board without limitations?I appreciate any advice you can provide as I'm eager to learn and progress in this project.Best regards, Vishwah (R&D Dept. 

CUBEMX, STM32G473 MCU is used.LIN communication worked well when using STM32F103, but after replacing only the MCU on the PCB board, LIN communication does not work.When the MCU was replaced, the HAL_Delay() function did not work,'#define USER_VECT_TAB_ADDRESS' I uncommented this statement and it worked fine.Did uncommenting this syntax affect LIN communication?When designing with CUBEMX, the STIMF103 board and Clock Configuration were designed identically. This image is CUBEMX Current LIN settings. If there is anything wrong, please provide a solution.
