Solved

I have designed my custom stm32f405 board based on Pyboard 1.1 and Adafruit Feather stm32F4 Express and was unable to enter USB DFU with it.I uploaded the code using ST-Link and can confirm that USB OTG FS works, without DFU the device is visible as Serial COM Port and works fine. Code I am using is built in Stm32CubeIDE.Unfortunately shorting BOOT0 pin with 3.3V leaves the board in reset loop and no device is detected by the computer. Microcontroller does not even enter DFU mode because when the connection is removed the code is executed just after.Additionally when BOOT0 is on 3.3V, PB13 pin is high for some reason (I have LED attached there), I couldn't find any information about that.I checked all the connections in schematic and I am almost sure everything is correct.So far I tried:different pulls on PC11 (up), PA10 (up and down), PB5 (up and down), PB11 (up) and PB2 (down)pull-up on PA9 if VBUS sensing was somehow activated (not in my code)desoldering LED that lits upI really hav

STM32WB50 is available at distributors, but RM0471 (mentioned in datasheet) doesn't seem to be available on product page yet.

Hello!. I Have two firmwares: bootloader and application. MCU is STM32L031K6U6First launched bootloader checking backdoor pin and launching appliction or starting firmware update process. If need just start firmware all work fine (bootloader don't change any registers - just executing jump to application)BUT! If need to update firmware - bootloader do init of LPUART and switch system clock to HSI 16MHz then processing commands from host. After this operations bootloader deinit LPUART and sys clock back to MSI and executind same jump to applistion.Main Application work at MSI 2.1MHz, but do initing this mode in any way at start.In result if Bootloader do change System Clock to HSI and then back to MSI - in appliction LPUART will not work. Appliction work fine, but can't send or receive bytes via LPUART.IF I change code of bootloader to skip change System Clock (continue work on MSI in bootloader) then application work fine after bootloader jump to them.What I do wrong?In Bootloader CPU

Hi there,I am new to the STM32 microcontrollers and the STM32 Cube IDE, and I'm tasked with including a binary set of data in a program. Most of the code is generated with the CubeMX program to help me with initialization. Please be advised, that I can't post the code in the forum.Traditionally I would do so by linking it into the binary file during build. However, in the STM32 Cube IDE I can't find any way or option to do so, so I've resorted to incude it as a C-style array of values. As this set of binary data can change, or may be exchanged completely a number of times during development, this is a hassle, and would be avoidable by just including/linking the binary dataset from a file, then using the symbol names.Is there a way to do this in the IDE, which I just haven't found yet?Best regards,Nils

Hello, I'm compiling a custom project with STM32M7 using TouchGFX library on it. Recently, when I started to play with more advance functions from TouchGFX I get this error during the linking process:.........../libtouchgfx-float-abi-hard.a(Math3D.o): In function `touchgfx::Matrix4x4::concatenateXRotation(float)':(.text._ZN8touchgfx9Matrix4x420concatenateXRotationEf+0xc): undefined reference to `sinf'(.text._ZN8touchgfx9Matrix4x420concatenateXRotationEf+0x18): undefined reference to `cosf'I check some of the flags -lm is included in the case that uses the default math.h functions, but the error is in a different place.I'm using libtouchgfx-float-abi-hard.a library and -mfloat-abi=hard.Can anyone help me with this?Thank you.

Hi, I was testing UART communication using F446RE Nucleo Board. I was sending data to COM port by a python program running in PC and trying the receive to same data.ser.write(serial.to_bytes([1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15])) print(ser.read(15))memset(rx_buffer,0, 15); HAL_UART_Receive(&huart2,rx_buffer, 15, HAL_MAX_DELAY); HAL_UART_Transmit(&huart2,rx_buffer, 15, HAL_MAX_DELAY);I'm getting below data.b'\x01\x02\x03\x04\x05\x06\x07\x08\t\n\x0b\x0c\r\x0e\x0f'I tried same code in two different board. both are giving same result.

Hello, I just got a STEVAL-MKSBOX1V1 a few days ago, and had a problem on trying the accelerometer with the ST BLE Sensor APP. When I keep the sensor's Z axis up or down, the APP shows consistent +1g or -1g. However, when I put the sensor's X/Y up or down, it always shows alternately +/- 1g values. Why? Please refer to the following screen shots.

Using the Distribution Package for STM32MP1 I'm able to access to the rootfs partition, example:my_postprocess_function() { cp -dr /home/osboxes/www ${IMAGE_ROOTFS}/opt/ chown -R daemon:daemon ${IMAGE_ROOTFS}/opt/www/ }But how to access to bootfs partition? For example to add the `boot.scr.uimg` or `rproc-m4-fw.elf`. I cannot find a `${IMAGE_BOOTFS}` variable.

There is a big issue I'm facing. I just installed STM32CubeIDE 1.2.0 but then I get an error when trying to install JLink_Linux_V662_x86_64.debI absolutely need those tools because I also do development for other boards with Segger JLink probes.What is going on? My system is Linux Pop!_OS 18.04 LTS x86_64

I am preparing the labs for the undergraduate embedded systems course at the university where I work (the University of Milano-Bicocca in Italy). This year we will change the hardware and we will start using the STM32 Nucleo F767ZI boards. I am a total beginner, so please bear me. I am preparing the usual "blinky" example, so I started STM32CubeIDE, I created a fresh project, did not touch the default pinout configuration, and proudly wrote my first code for a Nucleo board ever:/* main.c: */ ... int main(void) { ... while (1) { HAL_GPIO_WritePin(GPIOB, GPIO_PIN_0 | GPIO_PIN_7 | GPIO_PIN_14, GPIO_PIN_SET); PAUSE_CIRCA_ONE_SECOND; HAL_GPIO_WritePin(GPIOB, GPIO_PIN_0 | GPIO_PIN_7 | GPIO_PIN_14, GPIO_PIN_RESET); PAUSE_CIRCA_ONE_SECOND; } } ...To spice the things up a bit I wrote the pause code in ARM inline assembly:#define PAUSE_CIRCA_ONE_SECOND \ asm volatile("mov r0, #0x4400000\n" \ "sub r0, r0, #1\n" \ "cmp r0, #0\n" \ "bne .-6" : : : "cc", "r0");where I conside

I have a static LCD, a couple of other GPIOs configured as output and SWD which are all working fine. PA12 does not work when I configure it in output mode and i toggle the pin. I have tried using PA11 also with no success. The .ioc file of my project is attached. Thanks.

Hello everybody.I tried to develop a simple application, using a RGB led to produce variable colors in a continous way along the time and I still not have succeeded completely. Let me explain what is happening:1) I used STM32CubeMX 5.3.0 to configure PWM3 (Channel2), PWM4 (Channel 1) and PWM1 (Channel 1N) to control PWM signals respectively in PC7 (Red), PB6 (Blue) and PA7 (Green). These GPIOs are fixed and linked to the RGB led terminals mounted in a commercial shield. I´m using STM32 Nucleo for F1 Board (STM32F103RB MCU).2) I configured STM32CubeMX clock tree with PB1 and PB2 Timer Clocks with 0.0625 MHz (62500 KHz). My intention is to generate a PWM 500 Hz frequency with resolution value equal to 125.3) My initial configuration of the PWM channels in STM32CubeMX was:TIM4 (Channel1 = PWM Generation CH1; Clock Source: Internal Clock; Prescaler = 0; Counter Period = 125; Pulse = 62);TIM3 (Channel2 = PWM Generation CH2; Clock Source: Internal Clock; Prescaler = 0; Counter Period = 125;

Hello. I need ability to send only 8 bit at the time. And I can't figure-out why I can send it, it keeps generating 16clocks no matter what LL_GPIO_ResetOutputPin(GPIOA,LL_GPIO_PIN_4); Delay(0x8); while((SPI1->SR&SPI_SR_TXE)!=SPI_SR_TXE); SPI1->DR = i; while((SPI1->SR&SPI_SR_RXNE)!=SPI_SR_RXNE); b = SPI1->DR; i++; Delay(0x2F); LL_GPIO_SetOutputPin(GPIOA,LL_GPIO_PIN_4);By reading reference manual i know it has something to do with FIFO, but i can't chane anything for only 8bit communicationAny simple solution ?SPI INIT code:static void MX_SPI1_Init(void) { LL_SPI_InitTypeDef SPI_InitStruct = {0}; LL_GPIO_InitTypeDef GPIO_InitStruct = {0};   LL_APB2_GRP1_EnableClock(LL_APB2_GRP1_PERIPH_SPI1); LL_AHB2_GRP1_EnableClock(LL_AHB2_GRP1_PERIPH_GPIOA); /** PA4 ------> SPI1_CS# PA5 ------> SPI1_SCK PA6 ------> SPI1_MISO PA7 ------> SPI1_MOSI */ GPIO_InitStruct.Pin = LL_GPIO_PIN_5|LL_GPIO_PIN_6|LL_GPIO_PIN_7; GPIO_InitStruct.Mode = LL_GPIO_MOD

Trend Micro thinks TouchGFX\4.13.0, is a virus. It then instantly deletes the TouchGFX.exe file. This is the second time it has happened. The Violation is flagging as 'Unauthorized File Encryption' I know you said software doesn't use any file encryption. However the software "copies-, creates-, deletes-, modifies- and generates them" . Both times the software was flagged as a virus I had opened TouchGFX from inside STcubeIDE in an attempt to edit the tool and generate the code in cubeIDE. My assumption is it has something to do with TouchGFX writing to a file that is open in the ST IDE. I attached images of the program it is deleting and the target it thinks is the virus, which is a .png file I made inside the program. target is located in my C:/user/documents/etc... Thank you

I have gone through the methods that are gui generated when change screen transition is done through the designer. I have also gone through the previously asked question how to implement switchscreen() in touchgfx. However, sadly I don't understand exactly how to fulfill my requirement. I want to carry out transition whenever a certain boolean variable becomes true. The variable becomes true after response from the hardware. Please guide me on how to implement this. I shall be thankful.

I'm trying to use X-NUCLEO-NFC01A1 with STM32 F429ZI to read data from phone NFC.

I'd like to turn LED on or off according to UART receiving situation.What I'd like to do is following,1. If there is no receiving during 3 sec from last data, the LED is turned on (showing NO RECEIVING).2. When UART RX interrupt comes, the LED is turned off (showing RECEIVING) .I tried following code, but sometimes the LED turned on during receiving with 1 Hz rate  (one byte comes each 1 sec).// UART RX interruption (UART is 460800bps)void HAL_UART_RxCpltCallback(UART_HandleTypeDef *UartHandle){ <...turn LED off...> // I'd like to restart the timer interruption from 0 again. HAL_TIM_Base_Stop_IT(&htim2); HAL_TIM_Base_Start_IT(&htim2);}// htim2 has been set to 3s interval and started.void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim){ HAL_TIM_Base_Stop_IT(&htim2); <...turn LED on...>}I tried it with both of TIM2 or TIM4. The results were same.I think I should reset something when restart (stop and start) the timer intur

I'd like to use the system DFU on the L476 but Windows says "Device Descriptor Request Failed"Connect ST-Link USB for powerJumper CN7 VDD to Boot0Connect PA11 to white D-Connect PA12 to Green D+Connect USB GNDSB31 is in so Vusb has VDD already. Press Reset buttonNote this Nucleo model lacks an HSE, so the 48 MHz has to come from MSI which is supposed to be automatically trimmed to LSE on this MCU. So my expectation is that this should work. Am I missing something?
