This is one of those problems where I spent more hours than I care to explain.I've got a text box configured with a wildcard:In Designer, I've got a typography set to Voltage, 20px:Here's the typographies:Screen1ViewBase.cpp entry looks like this:   textCellVoltage.setPosition(191, 0, 67, 24); textCellVoltage.setColor(touchgfx::Color::getColorFromRGB(255, 255, 255)); textCellVoltage.setLinespacing(0); Unicode::snprintf(textCellVoltageBuffer, TEXTCELLVOLTAGE_SIZE, "%s", touchgfx::TypedText(T___SINGLEUSE_B9IA).getText()); textCellVoltage.setWildcard(textCellVoltageBuffer); textCellVoltage.setTypedText(touchgfx::TypedText(T___SINGLEUSE_F28R)); textCellVoltage.setVisible(false); ImplantData.add(textCellVoltage); Screen1View.cpp looks like this:void Screen1View::enableScreenElementsAfterInterrogation() { tab2.setAlpha(255); tab2.invalidate(); textCellVoltage.invalidate(); Unicode::snprintf(textCellVoltageBuffer, 20, "%s", "123"); textCellVoltage.setWildcard(textC

I have an STM32F103 board call 野火STM32F103ZE_霸道开发板，i found  enable  FSMC clock will pull up PB7  GPIO to 3.26v ,   i try decrease my code ceaselessly to verify this bug, finaly it can reproduce bug easily like this #include "stm32f10x.h" int main (void) { //RCC->AHBENR |= 0x100//RCC_AHBPeriphClockCmd ( RCC_AHBPeriph_FSMC, ENABLE ); *( unsigned int * )0X40021014 |= ( (1) << 8); } void SystemInit(void) { // nothing in here }Is this a problem specific to a single chip or a more general chip?

Hello,I am working On Customized Board using STM32H755ZIT6 microcontroller. I have written code using .IOC  functionality in stm32 CubeIDE but that code is not working in Our customized board. 2)That same code is working In Nucleo H755ZI-Q board and functionality is working.3)Than I tried to write code without using IOC for gpio toggling that code is working fine.4)Here is the code that is working    /* * main.c * * Created on: Nov 4, 2025 * Author: PK01 */ #include "stm32h7xx_hal.h" #include "main.h" GPIO_InitTypeDef GPIOD_Init = {}; void gpio_config(void); void gpio_config1(void); void delay(uint32_t delayVal); int main(void){ //HAL_Init(); gpio_config(); //USART3_Config(); gpio_config1(); /*gpio_config2(); gpio_config3();*/ // if(HAL_UART_Transmit(&usart3,(uint8_t*)msg,msgSize,timeDelay)!=HAL_OK){ // ErrorHandler(); // } while(1){ HAL_GPIO_TogglePin(GPIOA,GPIO_PIN_0); HAL_GPIO_TogglePin(GPIOE,GPIO_PIN_12); // HAL_GPIO_TogglePin(GPIOE,GPIO_PIN_8); // H

Parts i'm looking to connect * STM32N6 - microcontroller * LSM6DSV320X -  Master Sensor IMU * LIS2MDL - On sensor hub Magnetometer     Question - is there any benefit to connecting the IMU master sensor to the LIS2MDL on the sensor hub vs connecting it directly to the microcontroller.     One of the features of this IMU is to generate quaternions but i don't think i can add the LIS2MDL into that equation.  

HIWe have purchased few STM32H757 Eval board for initial evaluation. We received the boardsWe have generated code using STM32CubeMX and added just GPIO configs.(PK3,PK4,PK5 as outputs) and flashed code. it was working. we disconnected powersupply and connected back from then led's not toggling and also any code not flashing.and the output is No device found on the target. what may be the reason, how to overcome this. even tried in STM32CubeIDE still no luck.STMicroelectronics ST-LINK GDB server.

Heyho,I have a super-stable TCP-audio-streaming server on a H733 here, using custom ETH driver and lwIP, no OS.But I recently found that in a struct which is used for handling / storing the TCP connection, the variable to store the port number "u16Port" (used in lwIP's tcp_bind() to set the TCP port) changes as soon as data is transmitted.It's really crazy: u16Port has the init value before and after the connection is accepted, but as soon as data is transmitted, it changes all the time (checked via UART and http REST). When data transfer stops, it keeps the latest wrong value, after TCP connection is closed,  u16Port has the init value again.All other values in the struct do NOT change and their values make sense.I have tried to set the struct to volatile, use another memory area, align, but still changing.I just checked it with the STM32CubeIDE debugger under Live Expressions, there I see the same change.I admit I have no idea how I can check where this variable is modified.How

Hello All, I am facing a strange situationI have an ISR function1 that is triggered on Falling / Rising Edge of a GPIO pin This function1 according to the state of variable will either start TIMER2 and stop TIMER3 and the way around.TIMER2 & 3 have also ISR. But before starting/stopping TIMER, it needs to update memory variable that will be used by TIMER ISR.The issue is that the variable is effectively updated in memory after the start of TIMER and a few (100 CPU) cycles are needed to get the proper value.This is time critical and I need the value of wrBitPos to be 0 and wrBitCounter to be set a the right value before the first timer iteration. How can I fix this ?I use the volatile declaration for variable.void function1(){ TIM3->DIER &= ~TIM_DIER_CC4IE; // disable CC4 interrupt TIM3->CCER &= ~TIM_CCER_CC4E; // disable CC4 output TIM3->CR1 &= ~TIM_CR1_CEN; // stop the timer wrBitPos=0; bytePtr++; // Reset the BitPos wrBitCounter=by

Hello Everybody, I'm new in this place. I use an Evalboard ISC005V1 with STUSB4500 and an dedicate MCU to manage I²C port. I wanted to change the configuration of the PDO3 from 20V to 15V. I select PORT3 ( write 3 in 0x70 register ) I configure DPM_REQ_RDO3 register ( adress 0x91 )  with 0x96, 0xB0, 0x04 and 0x00. I soft reset the STUS4500  But nothing change. VBUS and PDO3 out still 20V???   What's wrong Thanks for the help!        

Hi everyone,I’m working with STM32L010K4T6, which is based on the ARM Cortex-M0+ core.I’d like to use FFT (Fast Fourier Transform) functions in my project, preferably within STM32CubeIDE.However, I noticed that the CMSIS-DSP library (which provides FFT functions) seems to have limited or no direct support for the L0 series inside CubeIDE.My questions are:Is it possible to add and use the FFT / CMSIS-DSP library with STM32L0 series MCUs like STM32L010K4T6?If yes, what is the recommended way to integrate it in STM32CubeIDE (manual CMSIS-DSP source import, or any ready package)?Are there any performance or memory constraints I should be aware of when running FFT on Cortex-M0+?Thank you in advance for any guidance!Best regards,Burak

Hi All, I'm using an STM32F1 with a 240x240 LCD screen that comunicates with the micro by SPI (with DMA). The screen uses the ST7789 driver (I supose it is not important). I'm working with RGB565 color format.The problem that I have is, for example, when I'm using the ST7789_Fill_Color(YELLOW); the SPI uses the DMA and the LCD shoul be yellow but it's not. If yellow is 0b1111 1111 1110 0000 the DMA only sends to SPI the LSB (0b0000 0000 1110 0000) witch is a wrong color.When I do the same without DMA it work's fine!The DMA is configures this way:I tried every configuration possible but nothing works. My question is why the DMA only graps the first byte of a color and what I have to change in order to send the real color.Thanks in advance!!!

Hi,  I want to count the time that an incoming level signal is high for. To achieve this I setup Timer 15 as a Gated Mode Slave, which has it's counter counting while the trigger input is high. The trigger input is the Filtered Timer 15 Channel 1. For some reason when I connect my signal to my input Timer. Nothing Happens. The signal on the IO Pin TIM 15 CH1  is a 2V square Wave.My own software seems correct. I then moved to Hal to see if I can achieve it.  I've tried to use HAL to achieve this without any luck here is my HAL software.Uploaded is the main and IOC fileI am working on the STM32G071Thanks 

I’d like to use the NUCLEO-N657X0-Q board together with the B-CAMS-IMX camera to output video to a computer as a webcam using CSI → DCMIPP → UVC.However, since all the CSI and UVC examples are provided only for the STM32N6570-DK, I’m having difficulty creating this setup. Although there are some examples for the NUCLEO-N657X0-Q, I’m struggling to understand the code. Is there a simple project or example that uses only CSI – DCMIPP – UVC?

Hello everyone,I'm working on a custom board with an STM32H563 and using CubeMX, HAL, and ThreadX.I am trying to receive variable-length UART data via DMA using HAL_UARTEx_ReceiveToIdle_DMA(). My problem is that the HAL_UARTEx_RxEventCallback never triggers for the HAL_UART_RXEVENT_IDLE event. It only triggers for HAL_UART_RXEVENT_HT (Half Transfer) and HAL_UART_RXEVENT_TC (Transfer Complete).SetupFunction Call: HAL_UARTEx_ReceiveToIdle_DMA()RX Buffer Size: 1000 bytesDMA Mode: CircularData Source: A peripheral sends packets of variable size (approx. 2048 - 4096 bytes) at 1,000,000 bits/s.Idle Time: There is a guaranteed idle time of > 45ms between packets. This should be more than enough to trigger the UART IDLE event.Here is the .iocHere is the RX line on the scope:ProblemExpected Behavior: Given the long idle time, I expect HAL_UARTEx_RxEventCallback to be called with an event type of HAL_UART_RXEVENT_IDLE after each packet.Actual Behavior: The IDLE event never fires. I only get H

I have several an 2 F401RE boards connected to my PCs and getting data by the Virtual Communication Port.Unfortunately when installing a new board on the PC, I ve seen that my 2 boards were declared by Windows with the COM portCOM port 7, 9 and 10 are allocated by Windows to others boards I am under the impression that there is a bug in the Virtual COM driver that do not authorize to declare a virtual COM Port beyond COM10.Is there a fix or a workaround. Otherwise Is it possible to reuse an COM port, for instance the COM 9. Is there a procedure to unsintall the COM9 in order to use for my new boardFinally, I would have connected in parallel, on my system, 3 boards with COM8, COM0 and COM10   

In application note TN1571 "Reference design based on the ST1VAFE6AX and ST1VAFE3BX biosensors..." Table 2 mentions that ST1VAFE3BX has a selectable 50/60Hz notch filter. However, there's no further reference to this filter or how to enable it in the datasheet.Is this an error in TN1571, or something I'm missing.Thank you.  

Hello,I have the LIS2HH12 chip in two separate boards, same board, same firmware.  These devices have been working well, producing X,Y,Z data.  Until today, that is, after a firmware update.This device is the only thing on the I2C bus, 100KHz, 5.1K pullups, 3.3V, connected to an ESP32 S3.  Waveforms on the oscilloscope look clean.The CTRL1 register gets 0x3F and CTRL4 register gets 0x04 which I believe should provide initial functionality.WHOAMI returns 0x41, but STATUS returns 0x00 and all six OUT_ registers return 0, as illustrated below.I have a feeling I've overlooked something really simple.  I've read both datasheet and appnote, and looked through this community for hits on the LIS2HH12.  Thanks for any thoughts or ideas.WHOAMI and STATUSOUT regs

Hi Support team, I am working on the FREERTOS based project and i need to disable the code generation for pendsv handler, systick handler, svc handler . As this handlers are written in freeRTOS, I am getting error for multiple definations. I have seen the option to skip the code generation in previous versions of the software but now i am not able to do so. you can see an empty page in code generation option. Please help solve the issue.    

Hi,I’m using an STM32L052 with LQFP32 package, VDD = 1,8V.According to the datasheet:“VDD_USB = 1.65 to 3.6V: external power supply for USB transceiver, USB_DM (PA11) and USB_DP (PA12). To guarantee a correct voltage level for USB communication VDD_USB must be above 3.0V. If USB is not used this pin must be tied to VDD or VSS. On packages without VDD_USB pin, VDD_USB voltage is internally connected to VDDvoltage”Since in the LQFP32 package VDD_USB is internally connected to VDD, it is therefore powered at 1,8V in my design.As expected, the USB interface does not operate when I connect the board to a PC and risk of damage because D+ and D- tied to 1,8VCould you please confirm that the internal USB PHY cannot operate correctly at 1,8 V, and that USB operation requires VDD ≥ 3.0 V even when VDD_USB is internally tied to VDD ?If so, what would be the recommended workaround for designs that operate the MCU at 1,8 V ?Thanks in advance for your clarification.
