Hello, I try to use a TIM2 Interrupt to toggle a LED. I use a STM32F401C controller. If I toggle the LED inside the while loop with delay, it works fine.       while (1) { HAL_GPIO_TogglePin(GPIOB, GPIO_PIN_15); HAL_Delay(1000); }       But there is no interrupt for TIM2. I attached the CubeMX ioc file. Have I forgotten something to parmatrize?

Hello STM32 Community,I am currently working on a USB Power Delivery (USB PD) project using an STM32L562CET6 microcontroller, where I successfully vary the output voltages and currents (5V 3A, 9V 3A, 12V 3A, 15V 3A, and 20V 5A) in SPR (Standard Power Range) Mode using the provided usbpd_pwr_if.c code.I am exploring the possibility of achieving the same functionality using a bit-banging method. Specifically, my goal is to configure the CC lines as GPIO in analog mode and generate the SPR signal pattern manually. I understand that USB PD communication involves precise timing and voltage levels, and I would like to confirm whether this approach is feasible with an STM32L562CET6 microcontroller.My Questions:1. Is it technically possible to achieve reliable USB PD communication using bit banging on an STM32L562CET6 microcontroller?2. What are the key challenges and limitations associated with this approach?3. Are there any specific STM32L562CET6 features or peripherals that could assist in

Hi all.Working with the Pack Creator I know I can create a header file that contains defines that are editable in the CubeMX view.I'd like to know if it's possible to have a pack that places defines in the project settings instead of a header file? 

I have an ADC connected to an STM32-L4P5DK. Data should be read in the background by the DMA controller. SPI TX is assigned to DMA1 CHANNEL2, and SPI RX is assigned to DMA1 CHANNEL3. Both DMA1 CHANNEL2 and CHANNEL3 are synchronized with EXTI1 (DRDY signal from the ADC). The STM32 SPI2 is configured as a full-duplex master. Both SPI TX(to transmit dummy bytes) and RX are synchronized with the external interrupt (pin PD1 is assigned to DRDY). The problem is that I can see the data on the scope, but SPI2 is not receiving any data.I start TX using the function:  HAL_SPI_Transmit_DMA(&hspi2, tx, 0x1b);  And receive the transmission using:  HAL_DMA_Start_IT(&hdma_spi2_tx, (uint32_t)adc_buf, (uint32_t)&(SPI2->DR), 0x1b); SET_BIT(SPI2->CR2, SPI_CR2_RXDMAEN);   DMA1 CHANNEL1, set to very high priority, is used to pull the chip select pin low on the DRDY falling edge. This channel generates a DMA request to control the CS pin.Ye

Could you shed some light on what the button "start wireless stack" actually does?1) Is there some flag in flash that has to be set after flashing the wireless stack? Or is it just an option byte or something?2) Why is this seperate button necessary? It would be easier and less likely to result in long debugging sessions if flashing the stack would automatically start it as well.3) Can this process be automated via the CubeProgrammer to have a single to click to install and start wireless stack?

Hi; I am using STM32U585ZIT6Q controller in my current project. I am enabled Trust Zone option. I have configured ADC 1 (4 channel) in non secure with GPDMA.I am not able to read ADC data. I have attached all configuration. I have used HCLK(160MHz) for ADC. if i got working example then it will more helpful. Please help me for same.

For example there would be a file called "common.h" containing a single line no #include or anything:../../../Common/Inc/common.hAnd in that path there is also a common.h containing the actual C code. The STM32Cube project structure is something like this with App1 and App2 being project folders so it is being used to link to common files.- Common/---- Inc-------- common.h- App1/---- Core-------- Inc------------ common.h- App2/---- Core-------- Inc------------ common.h It works so what I would love to know is how it works and what makes it work especially? Is it cube? If so, what in cube is it? How can I reproduce it?Grateful for any insight!Oscar

Hi, I'm trying to store some information in flash, I'm attaching the program. The problem arises when I use HAL_FLASH_Program function. Inside the FLASH_WaitLastOperation function (called by HAL_FLASH_Program), the PGSERR+PGAERR bits are set after the write operation. Do you have any ideas about this.?Thanks in advance// From datasheet rm0440-stm32g4-series-advanced-armbased-32bit-mcus-stmicroelectronics.pdf pag. 95#define ADDR_FLASH_PAGE_127 ((uint32_t)0x0807F800) // Bank 2void _qSaveConfig() {HAL_FLASH_Unlock();uint32_t page = _qGetPage(ADDR_FLASH_PAGE_127);FLASH_PageErase(page, FLASH_BANK_2);HAL_FLASH_Lock(); /* Check FLASH operation error flags */uint32_t e = HAL_FLASH_GetError();if (e != 0u) {qDebugFatalError("Errore in scrittura flash", e);} HAL_FLASH_Unlock(); // afesConfig == configuration to saveuint32_t sizeDataToWrite = sizeof(afesConfig);uint64_t dataToWrite[sizeDataToWrite];memcpy(dataToWrite, afesConfig, sizeDataToWrite); // Scrivi i dati nella memoria

Hello I'm using STM32F030C8.I'm writing the code because I want to use the internal flash memory like rom.Is there a set number of times I can write in internal flash memory? If there is a related document, I would like to see it.Thank you.

I have been using STM32F767zi for long time.I know some of the pin feature by heart.Last night, I enabled ETH for a moment and to see what pin it uses, then I disable it and then all the chaos happened.I realized that many of frequently used USART 2, USART3, UART5, USART6 pins are changed to other pins....I was like okay, then I follow to wire to the new pins, but it doesn't work well... weird.Then I reopen some other project of the  same board and realized that using same UART5, for exmaple, and saw that it was not that 2 pins as TX and RX.... Why and how is this happen?I tried to open new project, then pick the same Nucleo board, and immediately see the UART5 again, and WTF! another new pin?no, UART5 was all the while PB12 and PB13, USART3 is at PB10,PB11.... I have been using it for a year plus... Where come this PCx PDx and other new allocation that not actually working??Is this new update bug?Can anyone help how to load the really true working .ioc back?

Dear STM, May I know do you have product roadmap for Qi2.0 compliant 15W RX, due to obsolescent of Qi1.3 on 2026. 

I see lots of posts with folk struggling to get code into ITCM, but not the (sorta) problem I have after getting things working.  It is just a compiler warning, but I'd like to find an elegant way of handling it.The issue is I am using memcpy to copy my code intended for the ITCM from external flash to ITCM space.  All is good and it works, but since the start of ITCM is at address 0, GCC understandably questions my intentions as I'm doing a memcpy to NULL!  It's just a warning I've been living with, but I'm in a clean-up phase and would like to clear this warning. Options I've considered but none seem a clean solution:1) Use -Wnonnull option: Would work, but the warning overall is a good one and not a good idea to disable for the entire project.  There might be some way to disable it just for the file making the call, but still--ick.2) Manually copy the first 4 bytes (or something like that) and then use memcpy for addresses 4+.  This seems the least ugly

I am currently trying to perform the Cross-talk calibration procedure, but I am confused because the procedures mentioned in the documents "Proximity and ambient light sensing (ALS) module" and "VL6180X cross talk compensation implementation" are somewhat different.The document "Proximity and ambient light sensing (ALS) module" mentions that the offset needs to be written before performing the measurement, but this is not mentioned in the document "VL6180X cross talk compensation implementation."Additionally, the "VL6180X cross talk compensation implementation" document uses RESULT__RANGE_RAW. Could you please advise which one I should follow? Thank you. 

Hello -I have an Accel 28 board made by Mikroe that has the LIS2HH12 device. As per the Mikroe data sheet I set J1,J2,J3 to positions 2-3. I have removed J5 so that line isn't pulled up.I've got the first 6 pins on the lower left up connected to my NUCLEO-L476RG development board.GND, 3V3, SDI, SDO, CLK and CS. I have confirmed CS, CLK and SDI have normal and good signals. Yet, SDO is distorted, almost non-existent, but does return the correct value occasionally. Please see scope pix attached. Top is SDI/MOSI, bottom is SDO/MISO. I've also tried unplugging SDO pin from Accel 28 to STM32 to confirm it's not a loading issue. On this test the function did return the correct value of 0x41 to "Who am I" (0xF) command.It's clear to see this is a peculiar signal and not normal at all. Also attached is Accel 28 schematic.Could you please offer any suggestion as to what the problem might be? Have you seen this before?Thanks!

Hi STM community!I am new to STM microcontrollers and this is my first post :)My board is a tiny STM42F401CCU6 @ 84MHz. I already have made some first steps with CubeMX and CubeIDE, after I came from the arduino IDE which was a bit too simple (reading some ADC voltages, driving a 7-Segment Display with a shift register).Some day I want connect a HIFI DAC (PCM5102) to I2S in order to build a VA synthesizer, using a Half Duplex DMA Transfer. This is a challange for me, because there are so many things to configure in the CubeMX. The programming itself seems quite smooth thanks to the CubeIDE and CMSIS.My current focus is the clock configuration, which is quite complex stuff for MC beginners. I have watched some YouTube vids from STM but I wondered, why the I2S clock ist so high, when I configure a I2S interface. At any sample rates it is set to 96MHz, even when the HCLK is only 16MHz.I thought, the I2S clock is calculated by sampleRate*BitsPerSample*Channels, which is only 128kHz on

Hi all,we are developing a product with the STM32H573. The idea is to use the STiRoT for secure firmware update. The MCU is connected to a Linux CPU via SPI. Now we plan to do the provisioning during the production using the Linux CPU that has a ethrnet connection to the outside world. The question is: Is that possible? Is the boot pin required or is a jump to bootloader sufficient?I have modified the provisioning scripts to use UART and I have tested it using the H573DK eval board, but it failed. This is because after programming the option bytes the bootloader is not starting again, as STiRoT gets activated. Maybe the sequence can be modified?What are the detailed steps? E.g. what is the RSS doing and how? Thx,Roman
