Solved

I'm trying to talk to a device that sends a 122 byte message every 500 milliseconds at 115.2 KBaud. I can make it work with HAL_UART_Receive_IT() in a while loop as shown here. #include <stm32l4xx_hal.h> #include <stm32_hal_legacy.h>   #include <iostream> #include <string.h> using namespace std; #ifdef __cplusplus extern "C" #endif void SysTick_Handler(void) { HAL_IncTick(); HAL_SYSTICK_IRQHandler(); }   void lpuart1RXIdleCallback(UART_HandleTypeDef *huart); void configureUART();   static UART_HandleTypeDef s_UARTHandle = UART_HandleTypeDef();   #define RXBufferSize 122 static uint8_t RXBuffer[RXBufferSize]; extern "C" void LPUART1_IRQHandler() { HAL_UART_IRQHandler(&s_UARTHandle); }   void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart) { cout << uwTick << " RXBuffer: " << RXBuffer; }   int main(void) { HAL_Init();   configureUART(); while (1) { memset(RXBuffer, 0, sizeof(RXBuffer));

I've been driving myself crazy trying to learn STM32 programming. I've selected an STM32f103c8 to try and program. I've searched low and high, and have not found a detailed reference for the HAL libraries. Any links to such references or good tutorials would be great.

Hello everyone,I have a STM32H747I-DISCO and I am trying to use it with TouchGFX in the first part. But the problem is I cannot use it directly with TouchGFX "Run Target" mode.I have few errors, I tried to run as admin but it didn't work. I have the external loader file specified.Could you help me please ?Thanks,Simon

Existing STM32CubeIDE works great in Ubuntu 16.04 for STM32H747XI6. When I start it in MobaXterm in Windows laptop, I get these errors:./stm32cubeideSWT SessionManagerDBus: Failed to connect to org.gnome.SessionManager: Could not connect: Connection refusedSWT SessionManagerDBus: Failed to connect to org.xfce.SessionManager: Could not connect: Connection refusedIDE opens in the workspace, but I can not compile or debug the project.

I tried to modify the ViewBase file generated by the designer by adjusting the width and height of the circle progress but nothing happened and I could not resize this element at all. So Is there is any other method to have different sizes of the circle progress either before generating the code from the designer or even after generating it by modifying some other code ???

DS, RM and Nucleo-boards are already available, but I couldn't find a SVD file for the G0 series.

I am porting a project from STM32F105 to STM32F103 using the standard peripheral library. During the compilation process I get the following error:In file included from ../Drivers/STM32F10x_StdPeriph_Driver/src/stm32f10x_can.c:23:0: ../Drivers/STM32F10x_StdPeriph_Driver/inc/stm32f10x_can.h:47:49: error: 'CAN2' undeclared (first use in this function); did you mean 'CANx'? ((PERIPH) == CAN2))And if I go to stm32f10x_can.h file I can find:#define IS_CAN_ALL_PERIPH(PERIPH) (((PERIPH) == CAN1) || \ ((PERIPH) == CAN2))However, STM32F103 only define CAN1 in stm32f103xe.h. The question is how can I compile the standard library for STM32F103? One workaround is to delete all references to CAN2 but this is strange because the standard peripheral library is supposed to be standard for all mcu's in F1 family. In other words, no modification in source code of the library is needed to compile for those mcu's.Regards.

I have been following along with https://www.youtube.com/watch?v=-AFCcfzK9xcand I can see that each change made in CubeMX produces changes in my generated code in main.cHowever, I cannot find any generated code which links the Timer Output Channel 1 to my GPIO Pin PA5. Is it being saved somewhere else, or is it being saved in some obscure way that I've missed?

Hi,How can I easily write/read N213 tags using rfal v2.2.0?For the v1.3.2 version I used to call rfalISO14443ATransceiveFrame() to do it but I don't know how it's done in this latest stack version.regards,gaston

hello, I am trying to convert c project to CPP in STMCUBE IDE, Now I generate the code to STM32H745(Dual core) and convert to CPP by using convert to CPP option in CUBE IDE. I am getting following error undefined reference to `main'. (check in attached screenshot) But same way I generated code to single core MCU, I did not get this error. Now how can I resolve this issue.

HiI am trying to include the standard C++ libraries in my STM32CubeIDE code, however I am getting an "Unresolved inclusion" Error. This project is configured as a C++ program, as the project drop down menu only allows me to convert this project to a C program - which implies that the current project is configured as a C++ project. e.g.  Is anyone familiar with this issue and know how to resolve this ?a swift reply is much appreciated :)Thanks

I'm helping a friend fix his battery charger. The Micro processor in it is a ST6200. Its spec has a list of Application Notes including the AN433. But a search of the ST web site failed to find it - which seems odd. Any assistance will be appreciated.

The update system of CubeMxX don't work. Event at some time, the software don't run at all, only the ST logo appears and... nothing!

I'm moving my first steps on STM's CPU, and I would like to start playing with stm32f469i-disco.Where I can find an updated step-by-step guide to open a project on TouchGFX, export into a project on CubeIDE and successful play on the discovery board?Thanks.

Hello, is there any example available that implements audio reads from the from CN11 jack connector on 32F746GDISCOVERY board?

Hi,Greetings!I have a Bourns Rotary encoder https://www.bourns.com/docs/product-datasheets/pec11r.pdfconnected to PA11(ENCA)/TIM4_CH1 and PA12(ENCB)/TIM4_CH2.Trying to use the encoder as a input control for user input.This is what I am doing:  static void encoder_init(void) { LL_GPIO_InitTypeDef gpio;   LL_APB1_GRP1_EnableClock(LL_APB1_GRP1_PERIPH_TIM4);   gpio.Pin = LL_GPIO_PIN_11 | LL_GPIO_PIN_12; /* Enc A, Enc B */ gpio.Mode = LL_GPIO_MODE_ALTERNATE; /* Alternate function */ gpio.Speed = LL_GPIO_SPEED_FREQ_LOW; /* Low Speed */ gpio.Alternate = LL_GPIO_AF_10; /* AF10=TIM4 */ LL_GPIO_Init(GPIOA, &gpio);   LL_TIM_SetPrescaler(TIM4, 0); LL_TIM_SetAutoReload(TIM4, 100); LL_TIM_SetCounterMode(TIM4, LL_TIM_COUNTERMODE_UP); LL_TIM_SetClockDivision(TIM4, LL_TIM_CLOCKDIVISION_DIV4);   LL_TIM_DisableARRPreload(TIM4); // LL_TIM_SetEncoderMode(TIM4, LL_TIM_ENCODERMODE_X4_TI12); LL_TIM_SetEncoderMode(TIM4, LL_TIM_ENCODERMODE_DIRECTIONALCLOCK_X1_TI12)

Hi,I just got my H745i-DISCO board and started to tinker with ToughGFX right away. I got a test application loaded on the board, but once I disconnected the USB connection and reconnect it (USB connected to STLink USB Port on Nucleo board, power jumper in first position) the STLINK seems not to recognize the MCU anymore. The loaded flash drive contains a "FAIL.txt" file with the following content: "The interface firmware FAILED to reset/halt the target MCU".When I press and hold the reset button while plugging the USB and releasing it within 2 seconds, the FAIL.txt is not present. Either way, I can't get TouchGFX or STLink Utility to connect to the MCU. I tried all day and only got it to again recognize the MCU once. Then I did a full chip erase with STLink Utility and loaded another application with TouchGFX. Unplugging the USB, plugging it again, same error.What am I doing wrong? How can I get consistent results?What I've tried so far:Supplying the board via the scond USB power conn

Hi supporter,I use STM32Cube v1.10 on macos(Mojave) and linux(debian 9). The debug dialog has load mode option to choose production or engineering mode in stm32cubeide on linux system. But that dialog hasn't the load mode on macos.Below picture is debug dialog on macos.Does any thing I am missing to setup for stm32cubeide?

How to install it manually. IS there a oportunity to install it and keep it as a .zip-file?​

Hi,when switching from e.g. a C file to CubeMX file, the view is changed to Device Configuration view. This is also the case if the CubeMX file is already opened in the IDE. Closing the CubeMX file also restores the view back.However, switching to a C (or another) file while leaving the CubeMX file opened doesn't switch back the view. This is a bit annoying, because the view must always be changed back manually.Regards

Why did Viper113XS removed from eDesignSuite?Is there a problem about IC? I need to know that because I made a design and ordered the IC, if IC has some problems I need to change it.

Hello,I am trying to set up a CAN interrupt base communication system and it seems that IRQ handler is never called.Debugger goes through the CAN1_TX and then back to main function, so IRq is never called.USART output:[2020-12-08_21:19:01:191] AFTER  50.[2020-12-08_21:19:01:191]SYSCLK : 100000000Hz[2020-12-08_21:19:01:191]HCLK  : 50000000Hz[2020-12-08_21:19:01:191]PCLK1 : 25000000Hz[2020-12-08_21:19:01:191]PCLK2 : 50000000Hz[2020-12-08_21:19:01:191] BEFORE TX CALL.[2020-12-08_21:19:01:191] After TX call.[2020-12-08_21:19:01:191] END of program.Main:#include "main.h" #include <string.h> #include <stdio.h>   TIM_HandleTypeDef htim2; UART_HandleTypeDef huart2; FDCAN_HandleTypeDef CAN1;    void SystemClock_Config_HSE(uint16_t Clock_Freq); static void MX_GPIO_Init(void); static void MX_USART2_UART_Init(void); static void MX_TIM2_Init(void); void GPIO_Init(void); void CAN1_Init(void); void CAN1_TX(void); void CAN1_R
