STM32 MCUs Products

Hello, My board is STM32F429I-Disco1, the LED pin is PG13 and PG14, and the pins are set to 1. (So, after I click the run button，the LEDs light up). After I write the code "HAL_GPIO_TogglePin(GPIOG, GPIO_PIN_13);" and "HAL_Delay(500);" in the "while (1)" of main.c, I click the run button and the console shows "Download verified successfully". But the LED does not blink.When I click run button，startup_stm32f429zitx.s appears next to main.c . The 61st line ("ldr sp, =_estack /* set stack pointer */") of startup_stm32f429zitx.s  is marked. May I ask how to handle this problem? Thank you very much.

Hi all,I'm having issues getting ROP Level 1 setup on an STM32L412.Below is the code which is run pretty soon after every reset.After ROP has been set, and the system reset, ROP always reads back as 0xAA which leads to a boot loop of this function being run.Strangely though, to erase/re-program the flash using a JLink, i first need to remove the ROP protection.Any idea's what I'm doing wrong?  void Flash_Protect() { //check RDP level uint32_t rdp_level = READ_REG(FLASH->OPTR) & FLASH_OPTR_RDP; if (rdp_level == 0xAA) { //currently LEVEL0=0xAA (LEVEL1=0xBB) //no read out protection is active //disable flash read out to external devices DEBUGS("FLASH IS NOT PROTECTED\n"); //flash unlock if (READ_BIT(FLASH->CR, FLASH_CR_LOCK) != 0U) { //authorise the FLASH Registers access WRITE_REG(FLASH->KEYR, 0x45670123U); //flash key 1 WRITE_REG(FL

In my graduation project, I'm utilizing the STM32H735_DK microcontroller to communicate with a GMSL (Generalized Memory Scalable Logic) device. Typically, these devices are configured using terminal programs like Putty or TeraTerm. Commands, such as "PICT START," are sent via a USB A to USB B cable from a PC to the GMSL.  

Hello,I'm designing an electronic board with STM32H747 microcontroller. This is my first time using a microcontroller with 2 cores.I would like to ask some questions about bootloaders:- how do I select bootloader over I2C (I2C1 on PB6/PB9 pins)?- at what logic level should I put the BOOT0 pin?Thanks to who helps me.

Hello, first of all, thanks for all the previous help to everyone. I want to debounce my input, using registers, but I'm running into the issue of it "not working" I am surely missing something in the logic I am overlooking.here is my interruptvoid Interrupt_Init(void){ EXTI15_10_Init(); NVIC->IP[EXTI15_10_IRQn] = (1 << 4); NVIC->ISER[40 >> 5] |= (1 << (40 % 32)); } union InterruptFlag { struct { volatile bool flag: 1; // Just one bit for our flag volatile bool press: 1; } bits_access; uint32_t reg; // We'll use this for byte access }; volatile union InterruptFlag flag = { .bits_access.flag = 0 }; // Initialize to 0 volatile uint16_t pressTime; volatile bool lastButtonPress=0; volatile bool buttonPress=1; void EXTI15_10_IRQHandler(void){ flag.bits_access.flag = !flag.bits_access.flag; EXTI->PR |= (1<<13); // Clear PR to re-enable EXTI interrupt }

Hi Team,we are facing issue with flashing NUCLEO-H7A3ZI-Q board.is any problem if we flash stm32h7a3zit6 code on stm32h7a3zit6q.can we give a suggestion ASAP

Hi, I need to use USB in 2 modes:1. See SD card files interfaced to controller through computer via USB2. Transfer SD card files to "data storage device (USB stick)" via USBAny examples for same? Display menu should handle above operations. Since the implementation is new to me what middleware's are needed? a. FATFS: SD cardb. FATFS: USB Diskc. FreeRTOS: is CMSIS needed with FreeRTOSWhat USB be configured to:i. OTG/ dualii. Hostiii. DevicePlease check and guide. 

Hi ,While  I am learining the TIM1 of STM32F030RB . Configured TIM prescalr and ARR at diffrent value to get various Update frequency . when I create 1 second it is able to create .But when i try to create below the 38 micro second the update event still at 38 micro second (maximum 26 KHz) Why so ?What is the maximum update event trigger frequency for TIM1 ,is there any limit .?I used to try 1 micro second update event trigger frequenct but not working  what is the technique behind it ?how achive in nano second and micro seconds  What is the supported values for Prescaler and ARR for proper operations   or How to choose ARR and Prescalar values ?is there any documents for it ?@AScha.3

I want  to understand the sequential steps involved in developing STM32 programs. Could you please provide me with a concise breakdown or outline of these steps?

Hi,I have these two functions ( see below ) that simulate, respectively, a positive and negative quadrature.  void TIM3_Configuration_positive_quadrature(void) { TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure; TIM_OCInitTypeDef TIM_OCInitStructure; int Period; Period = 1000 / 1; // TIM_Cmd( TIM3, DISABLE ); TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up; TIM_TimeBaseStructure.TIM_ClockDivision = TIM_CKD_DIV1; TIM_TimeBaseStructure.TIM_Period = 1000 - 1; //the prescaler is divided by 2 because the toggle mode (see below) halves the frequency. TIM_TimeBaseStructure.TIM_Prescaler = ( TIM3_FREQ / lastSetFrequency ) / 2 - 1; TIM_TimeBaseInit( TIM3, &TIM_TimeBaseStructure ); TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_Toggle; TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable; TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_High; TIM_OCInitStructure.TIM_Pulse

firstly we connect stlink v2 debugger to the  cube programmer later it connect and i get the blue led that show the connection ..after i make all the thing on stm32cube ide and debug according to the video of PHILL LAB after that neither program upload nor it connect to the programmer.cube programmer show stlink not connected where as it show accurate voltage.

I'm trying to get SPI1 working on an STM32U575 (NUCLEO board), starting from a base of existing working STM32F4 LL API code, but have failed.I am running this on a NUCLEO-U575ZI-Q board, so MOSI on PA7 (D11), MISO on PA6 (D12), SCLK on PA5(D13) and with SB63 not bridged so that I can use PB0 (the "IO1" pin of the QSPI pins on CN10) as NSS.Probing the pins, the SPI1 SCLK does not activate when I attempt to transmit data and the NSS pin stays high (it goes high when I configure SPI1 so it is working, after a fashion).  Not sure whether it is relevant but writes to CR1 do not modify the CR1 register contents as seen by the debugger, almost like SPI1 is not enabled (writes to other registers are visible in the debugger).  Here

Hi Team,I'm trying to check the PWM generation using STM32H7A3ZIT6 controller. I can be able to see the PWM generation only under debug mode using STLink-V3set. After power reset the software is automatically getting erased from the flash memory. Now the device itself not detecting while I'm trying to flash again the code (Failed to start GDB server in stm32cubeIDE) (No stm32 target found error showing in the stm32CubeProgrammer). Give any solution to resolve the connection issue and share any support components or ICs to add into our circuit. And I have attached the circuit diagram images for your reference.

Hello fellow seniors:I am still in the learning stage and currently use the part of writing to the memory (Flash Memory). I have encountered a problem and would like to ask for advice:From the picture (instruction manual) of [[Figure 1]], we can see that the blocks that can be written in the memory are 0x08000000~0x08080000For the following questions, please refer to [https://youtu.be/iMChxrvMNG0]Because I opened the memory to see that some user variables used the previous memory. I was afraid of being overwritten and changed it to 0x8020000 t

My project crashes after a random period when sending network traffic (one hour or longer working). I want to debug (but without a debugger connected or sitting there and waiting). So, I want to record some data, e.g. when the HardFault_Handler was called, to verify on which location in code the fault happened.In order to do so, here the approach:if a HardFault_Handler is called - it stores important info (e.g. LR, PC, XPSR, CFSR, ABFSR) in Backup Registers of RTC (to let this data survive a reset: no idea if memories, even Linker Script using NOLOAD attribute on memories, would survive a reset: if SRAMs are power cycled, reset, ... data gets lost, therefore RTC backup registers which are not "touched" on a Reset)if FW crashes (all dead, indicated by a flashing LED) - I want to press reset and with a next command when back again I want to print the Crash Report (command "cr" via UART)All works so far, just:The HardFault_Handler can be a

Hello, I was controlling the LTDC image with STM32F429II (Flash 2MB, RAM 256 + 4KB) from ST.I think there is an error in memory allocation, so I leave a question.The compiler i use is IAR.Currently, we have implemented the RGB888 image as 1.22MB size of the array => const uint8_t RGB888_854x480 [1229760] directly into the code LTDC.c and designated the RGB888 image as 854x480. The LTDC initialization utilized the demo code of the Standard Peripheral Library (SPL) provided by ST and used the same structure as the initialization and image structure like /// const uint8_t RGB888_854x480 [1229760]={0x00, ...};In my case, I referred to the LTDC manual AN4861 provided by ST, and it shows the fastest performance when used for Internal Flash Memory and for the STM32F429II series, it says Up to 2M... I tried using it, but I'm having the problem

After downloading the latest version of MC workbench required drivers and the latest firmware. I am still getting the following error in the IDE- "Connection Failed! No response, check communication cable, the power or the baudrate(set to 9600)". Please help.

So here's the code ; The issue with it is that whenever I press the button, weird things occur, such as my output resetting completely-going to the maximum, at my output I have a variable PWM signal void PB_Init(void){ RCC->AHB1ENR |= RCC_AHB1ENR_GPIOCEN; GPIOC->MODER |= ( 0x0 << GPIO_MODER_MODE13_Pos); GPIOC->PUPDR |= ( 0x1 << GPIO_PUPDR_PUPD13_Pos); } void EXTI15_10_Init(void){ PB_Init(); // Initialize PC13 as input. RCC->APB2ENR |= (1<<14); // Enable System configuration controller SYSCFG->EXTICR[3] &= ~(1<<7); // Select Port C as source, EXTIx = 0b0010 SYSCFG->EXTICR[3] &= ~(1<<6); // Select Port C as source, EXTIx = 0b0010 SYSCFG->EXTICR[3] |= (1<<5); // Select Port C as source, EXTIx = 0b0010 SYSCFG->EXTICR[3] &= ~(1<<4); // Select Port C as source, EXTIx = 0b0010 EXTI->IMR |= (1<<13); // Disable interrupt request mas

Hi,i am testing the ADC at the moment, and the values i get out of it look pretty good. Except, when using a squarewave.See my video: https://www.youtube.com/watch?v=TmKADM2yQvU The manual states for having the ADC run from AHB clock: "... has the advantage of bypassing the clock domain resynchronizations. This can be useful when the ADC is triggered by a timer and if the application requires that the ADC is precisely triggered without any uncertainty ...". But as can be seen, there is an issue, as the blue signal (which represents the bits of the adc - derived from tim2 pwm) does some "steps" over a period of about 1.3us. It does not so when inputting a triangular wave.Anyone has experience here? Or any id

Hello everyone,First of all, I want to say that I have a very limited knowledge about C memory stuff, so a bit of guidance would be of help. I am trying to set up a timer-triggered multi channel ADC with DMA, which I have already succesfully achieved, but as I implement other pieces of code, the DMA buffer either fully stops or does very strange things like swapping around the positions of the channels. I have realized this because commenting out parts of the interrupt of the timer or setting up the ADC with another timer works, so I suspect I am doing something very wrong with pointers usage or variable declaration. I would like to ask for a bit of help figuring out what am I doing wrong. I'll attach the whole project for if anyone wants to take a closer look. Thank you in advance! :) Here are the code snippets Here's the code ran just before the while(1) loop (invLeft is declared as extern and it's just a big struct holding

I have TIM20 configured in reset mode and I want the output of COMP7 to reset it. I have TIM20 configured with ETR routed to COMP7 and I can see the timer being reset on both of the edges of the COMP7 signal. I only want TIM20 reset on one edge. I'm using CubeIDE and I see options for choosing rising\falling\both for input capture, but no way to do it when routing from the internal comparators. Is this possible?

Hi, I have this function to simulate a quadrature outputvoid TIM3_Configuration_positive_quadrature(void) { TIM_OCInitTypeDef TIM_OCInitStructure; int Period; Period = 1000 / 1; // 1 Hz - 1 second on, 1 second off duty TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_Toggle; TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable; TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_High; TIM_OCInitStructure.TIM_Pulse = (Period * 1) / 4; // CH3 at 25% TIM_OC3Init(TIM3, &TIM_OCInitStructure); TIM_OCInitStructure.TIM_Pulse = (Period * 3) / 4; // CH4 at 75%, ie half cycle later TIM_OC4Init(TIM3, &TIM_OCInitStructure); } When I set 1000 Hz as frequency (controlled by oscilloscope that is correctly set) after calling the quadrature function above the frequency becomes half. Any idea on why of this behaviour?

Hello ,I am generating PWM wave of 16khz ,by using TIM1 ,the Duty cycle updating from the DMA array in circular mode .(to generate sinewave ).And worked as expected . The TIM1 is configured the Trigger (TRGO) to update event.Now i want to sample ADC with a 124 micro second (as per the PWM frequency)The TIM1 update event  should trigger the ADC ,to sample  and need to save the data via DMA.how to configure it I triedout some of configuration dosent working correctly please help me uint32_t ADC_RES[200];HAL_ADC_Start_DMA(&hadc, (uint32_t*)&ADC_RES,200);HAL_ADC_Start_DMA(&hadc, (uint32_t*)&ADC_RES,200); I have configured as follows , But i didnt get 124 micro second sample why ?  static void MX_ADC_Init(
