Hi,I have plenty of embedded code that was written in a mixture of C/C++ with target of NXP processors, now I am going to port it onto STM32 targets, I wrote a mini class OutputPort as a test in CubeIDE: OutputPort.h: #include "stm32f767xx.h"class OutputPort{public:OutputPort(GPIO_TypeDef* gpio, uint16_t gpioPin);virtual ~OutputPort(); private:GPIO_TypeDef* gpio;uint16_t gpioPin; public:void Toggle();void Set();void Reset();}; OutputPort.cpp: #include "OutputPort.h"#include "stm32f7xx_hal.h" OutputPort::OutputPort(GPIO_TypeDef* gpio, uint16_t gpioPin){this->gpio = gpio;this->gpioPin = gpioPin;}OutputPort::~OutputPort() { }void OutputPort::Toggle() { HAL_GPIO_TogglePin(gpio, gpioPin); }void OutputPort::Set() { HAL_GPIO_WritePin(gpio, gpioPin, GPIO_PIN_RESET); }void OutputPort::Reset() { HAL_GPIO_WritePin(gpio, gpioPin, GPIO_PIN_SET); } main.c :/* USER CODE BEGIN Includes */#include <OutputPort.h>/* USER CODE END Includes */ /

Hello,I wonder if it is or it is not possible to use more than one ADC independet of each other. My problem is as follows: I want to use ADC1 and ADC2  in independent scan conversion nothing works anymore. My code work for ADC1 alone   or ADC2 alone,     uint32_t courant1;// TENSION VIA LE CAPTEUR uint32_t courant2;// TENSION VIA LE CAPTEUR /* Private variables ---------------------------------------------------------*/ ADC_HandleTypeDef hadc2; ADC_HandleTypeDef hadc3; /* Private function prototypes -----------------------------------------------*/ void SystemClock_Config(void); static void MX_GPIO_Init(void); static void MX_ADC2_Init(void); static void MX_ADC3_Init(void); /* USER CODE BEGIN PFP */ void HAL_ADC_ConvCpltCallback(ADC_HandleTypeDef* hadc) { if (hadc->Instance == ADC3) { courant1=HAL_ADC_GetValue(&hadc3)*20.5/4096; HAL_ADC_Start_IT(&hadc3); } if (hadc->Instance == ADC2) { courant2=HAL_ADC_GetValue(&amp

Hi Gfx Team,Could you consider adding an option to screen item in Canvas to exclude a screen from build/code generationThanksFerro 

Hi Gfx Team,When I try to call Line::setLine ()touchgfx::Line line {}; line.setLine ( .5f, 7, 5.5, 7 );my MSVC compiler saysError C2672 'touchgfx::Line::setLine': no matching overloaded function found Error C2784 'void touchgfx::Line::setLine(T,T,T,T)': could not deduce template argument for 'T' from 'int' Error C2782 'void touchgfx::Line::setLine(T,T,T,T)': template parameter 'T' is ambiguous Error (active) E0304 no instance of function template "touchgfx::Line::setLine" matches the argument list I tried and it seems to help when Line::setLine () is defined like this:template <typename T1, typename T2, typename T3, typename T4> void setLine(T1 startX, T2 startY, T3 endX, T4 endY) { setStart(startX, startY); setEnd(endX, endY); } template <typename T1, class T2> void setStart(T1 x, T2 y) { setStart(CWRUtil::toQ5<T1>(x), CWRUtil::toQ5<T2>(y)); } etc. Do you think you could change function templates to this form ?ThanksFerro 

Hello,We encountered a problem with the internal Bootloader of the STM32G0B1KBU6 MCU.ConditionsFirst, the option bytes are set with an STLINK-V3 programming adapter (SWD interface) and CubeProgrammer (2.15.0) according to Pattern 11 of AN2606:nBoot_SEL => uncheckednboot1 => checkednboot0 => uncheckedReproduction1. In our product assembly process:Initial programming of the user software is successful with STLINK-V3 Programming Adapter via SWD interface. Stm32flashtool is used to flash the controller at I2C address 0x5d. Pin PB6 and PB7 are used to access I2C bootloader.2. Trying to reprogram the controller while testing:Now, with the software already running on STM32G0B1KBU6 (verified) we go through the STM bootloader activation Pattern 11 (AN2606, Sec. 4.1) with pulling boot0 and reset low, then pulling boot0 and afterwards reset high.Expected3. MCU is reflashable via I2C bus.Observed3. As soon as the bootloader is addressed by an erase or flash command with the stm32flash too

Hello,we use an STM32WB55 with an RTC backup via a super capa.when the Vbat voltage drops below 0.6V, the RTC registers are no longer incremented.if the board reboots at this point, we have a datetime offset.is it possible to detect this problem when the STM32WB55 starts up?thank you in advance for your help

Hello,We are using ST25R3920B as NFC reader for our project. The communication is through SPI between mcu and NFC reader. I configured a GPIO as an interrupt and wrote a callback function for this GPIO.At the end of the callback function, interrupt flag is cleared. Inside this callback function, a task is notified. Before jumping to the task, interrupt flag is cleared at the the end of the callback function.The task I notified will call the "st25r3916CheckForReceivedInterrupts" function.However, I use this GPIO's status (HIGH, LOW) in order to read some registers in the task. Because I clear interrupt, I am not able to read this pin as HIGH. Operating system is FreeRTOS. That's why, I can not put this read operation inside Callback function because I use SPI_send function in this read operation. Problematic part where the GPIO's status is read inside "st25r3916CheckForReceivedInterrupts" function by reading "platformGpioIsHigh".If interrupt flag is not cleared, the syste

Hello Team,I have implemented ADC_DMA (circular mode) Multiple channels in NUCLEO_H745 and in that added ethernet without RTOS when ethernet is implement ADC_DMA is not working it provide only one time data but i have configured for circular mode every 1HZ I need to get new data but after ethernet is implemented I am getting only I time data, So is there any memory mapping I need change any configuration in code?PFA BelowBest Regards,Gagan Gowda G R

Hey, I am using STM32F407 and I am trying to configure the ethernet peripheral (and LWIP) with the cubemx with no success. I cant ping my board.Please anyone can help me with this?

HiI have a problem with my board with STM32L496ZGT6.Some boards works fine (so.. i think there isn't a project problem) some boards are in loop during the power on.I exaplin better:Here a function in main.cpp:  /*Configure the main internal regulator output voltage...............................................*/ if (HAL_PWREx_ControlVoltageScaling(PWR_REGULATOR_VOLTAGE_SCALE2) != HAL_OK) { _Error_Handler(__FILE__, __LINE__); } void _Error_Handler(char *, int) { while(1){} }  If I comment:  /*Configure the main internal regulator output voltage...............................................*/ /* if (HAL_PWREx_ControlVoltageScaling(PWR_REGULATOR_VOLTAGE_SCALE2) != HAL_OK) { _Error_Handler(__FILE__, __LINE__); } /*..... The board power on reguarly so it means: HAL_PWREx_ControlVoltageScaling(PWR_REGULATOR_VOLTAGE_SCALE2) != 0 This is esay but why does this happen?Hardware problem?Here the function HAL_PWREx_ControlVoltageScaling:

Hi, is it necesarry to use a crystal oscilator for DFU USB booltloader for STM32F427zit? Can I use a generator instead of crystal? Marcin

Hello,I have finally received a voucher to get a free NUCLEO-H563ZI board when attended workshop "STM32H5: Ultimate combination of performance, integration and affordability".Despite following the procedure provided in mail I'm unable to get past Place Order, no matter what operating system (Windows, Linux, Android) and browser (Firefox, Opera, Chrome/Chromium, Brave) I was using. I assume the coupon is working as the price and shipping has changed to free after applying it. There can be moving bars after clicking the Place Order button, but nothing really happens, no webpage changed, no order confirmation received.After coupon removal the shop allow me to get to payment method, but I don't want to finish this for obvious reason.Is there something I'm doing wrong? Or who should I contact to solve order problem using e-shop?Thank you

I am trying to launch a MC Workbench project targeting a STM32G431CBUx mcu as the controller. I tried to modify an existing control board file to use the STM32G431CBUx as the mcu. I am able to select my custom control board on the selection page, as well as accompanying power and bridge board. However when I click "OK" in the bottom right corner to try to open the project I get a popup with this message: "The hardware selected is not compliant with the selected algorithm. Please review your selections"Wondering why I am getting this error. Is the STM32G431CBUx mcu simply not supported at this time? Is there an alternative way to open an MC Workbench project with my intended target mcu?

Dear All,My questions are1). Does ST25R3911B also support Apple: ECP v2.3 (or later)?.As per the latest apple support doc to enable Apple NFC integration device chipset should support Apple ECP v2.3 (or later) Protocol with ECP 2 polling protocol.Apple Doc link :  https://register.apple.com/resources/docs/apple-pay/access/program-guide/use-cases/access-nfc-transactions/#key-nfc-features   2). Which are the Chipsets from ST, support Apple ECP v2.3 (or later) Protocol?We wanted to integrate Apple ECP v2.3 (or later) Protocol in our NFC enabled device for Apple certifications process. Please let us know. Regards, Gaurav.  

Hi all, im using Cube IDE STM32H743ZI2 Evaluation boardim curently sampling ADC2 and storing the output at an internal array using DMAthe array size is uint16_t[100,000]my requirements as to store much more data which means i have to use a diffrent memory sector.i was hoping i could use flash for that matter but the examples that i tried online.i was wondering is that kind of thing even possible?do i need some external flash memory for that matter?my final goal would be storing around 1M samples during about 1-2 seconds  which sums up at about 1Mbwhat is the right approach for that matter?according to the reference manual i should be able to access flash memory via D2->D1 AHB BUSThanks! :)   

Hello,I recently upgraded to CubeIde 1.6.0 but I am having many new problems when programming STM32h/43: the configurations generation is much slower and it often stops updating all needed files, which forces me to reboot (I could not find a better way).So I decided to downgrade to 1.5.1 which was stable for me, but I cannot load the .ioc files that were generated with 1.6.0. Is there a workaround?

I need USB interface STM32F373 for circuit.

Three states on a single GPIO pin with two LEDs is possible.For users who want to drive 2 LEDs with three states with one signal GPIO - please, see the details below.But I want to ask one question:On a STM32U5A5 - how does the PC13 behave? - I see "FOUR states" possible (even I can force later just to use three states).MCU was never flashed with a FW: both LEDs are on (dimmed, like getting pulses)both LEDs off: configure PC13 as input (or GPIO_DeInit() to set as analog pin)LED1 on / LED2 off: configured as output and drive lowLED1 off / LED2 on: configure as output and drive highI cannot force again to see both LEDs on.But I am sure: after I have soldered my boards, power it up the first time in order to flush the 1st time my FW - both LEDs are on (but dimmed). I assume: there is a frequency (a toggling signal). But why and which one?BTW: how to configure PC13 for RTC_OUT1? I have not found an ALT setting to do so?One GPIO pin for three statesUse a Dual-LED with two LEDs, "anti-paralle

I use STM32CubeMX and Keil MDKI generate code and open project , but only open project.eww..-. 

Hello ST community,In the software STM32CubeMX there is the possibility to select different timebase sources. By default the SysTick is selected. What criteria should be considered to decide which timebase to use ? What is the advantage/disadvantage of the other timebase sources? Is there an effect on precision or on energy consumption.Are the other timebase options relevant for applications with an RTOS only? Mostly I read that in combination with a RTOS the SysTick is not used for unknown reasons.Many thanks

My STM32F745VET project was built in MX v6.3.0 and uses FreeRTOS. When SysTick is dedicated to the RTOS I get the following message when I try to build code:"When RTOS is used, it is strongly recommended to use a HAL timebase source other than the Systick. The HAL timebase source can be changed from the Pinout tab under SYS"I arbitrarily picked TIM14 for the timebase source and see it has priority 15 in MX, the same as the FreeRTOS tick ISR. The code that MX generates does set the TIM14 ISR priority to 15 in HAL_Init(), but subsequently sets it to "16" in SystemClock_Config() when it calls HAL_RCC_ClockConfig(). This 16 gets truncated to 0 and this ISR interrupts my critical sections of code.I believe this is just a bug in the code generated by MX? I manually fixed it but that solution is not optimal and it'd be better to simply not have this ISR. What risk makes MX "strongly recommend" having a separate HAL timebase?
