 I can't find the correct answer from Internet and I don't know do I need to write some code to USART /UART. I have those initialized by code generated by Cube MX.

Debugging on STM32H753-EVAL2 board with Atollic.Sometimes the debugger gets into weird state while target is running.Only full stop (red block) and reset buttons are active. The break button (||) is grayed.Has somebody seen this behavior?I thought it is caused by some exception, inserted BKPT(0) in all exception handlers (it is a ST example from Cube package, with Ethernet and FreeRTOS. AFAIK it does not attempt to sleep)But no breakpoint is hit. Usually only power cycle can recover from this state.Restarting debug session fails - cannot connect to target,Thanks for any idea...-- pa

Hi,I have built some bootloader for different application and I was wondering if, in some way, I can check if the file dfu is the one related to that application. I tried to change the PID and VID when I create the file with dfu file manager (as shown in figure in attached), but it does not change anything, I mean, I could write whatever I want and it still works. The version of the DfuSe is the v3.0.6. Can someone help me please? Thanks.

I am using STM32CubeIDE to generate a code and want to transmit two different data(voltage and temperature of battery) serially . I am able to transmit single data at a time means i am able to check voltage or temperature individually but when i am trying to send both the data simultaneously ,facing some problems like it reads only one data or getting data of voltage and temperature alternately .But i want to get separate data for further use. Please give me any suggestion.

I got my Bluepill STM32F103C8T6 device working in the Arduino IDE with the STM32duino bootloader recently.I was curious about 16bit PWM as opposed to the crude PWM output of standard Arduinos.Using core 'maple' from platform in folder: C:\Users\dentaku\Documents\Arduino\hardware\Arduino_STM32\STM32F1I can do pwmWrite and get a very high resolution 16bit PWM.I have an optical encoder that updates a variable which I use to change the value of pwmWrite and 2 LEDs conected to PA8 and PA9 fade up and down according to that value.but... switching over to ST's arduino core which doesn't use pwmWrite but just regular old analogWrite.Using board 'GenF1' from platform in folder: C:\Users\dentaku\AppData\Local\Arduino15\packages\STM32\hardware\stm32\1.7.0Using core 'arduino' from platform in folder: C:\Users\dentaku\AppData\Local\Arduino15\packages\STM32\hardware\stm32\1.7.0 In void setup () I set the resolution to 16analogWriteResolution (16);in my main loopif (lastValue != encoderValue) { //onl

I need sine modulated PWM during +ve half cycle of sine wave and zero output during -ve cycle of sine wave. Desired samples of sine are 200. I have attached the MATLAB simulation circuit snapshot. Problem is that I am getting 5Hz freq.

Hi,Im using the System Workbench and a strange behaviour occured to me.When a certain halting point is reached, Im not able to step to the next one. Pressing Resume brings me back to the very same halting point, stepping over aswell. And stepping into always brings me to the Ethernet Interrupt Handler.Is this by design or a bug?

I mean which file I need to put from attolic project to debug it from STM Studio, as .elf , .axf , .out file is not available in attollic generated files.Thanks

Just download en.x-cube-aws.zip, it is STM32CubeExpansion_Cloud_AWS_V1.4.0.I use TrueStudio to import the STM32F769I-Discovery_AWS project, it works, I can view the project files. But when I build the project, it comes "Info: Nothing to build for NUCLEO_F429ZI".How to fix it?RegardsSam

I am getting warnings that AccY, AccZ and Avg are not being used.

Hi,I maked a .ioc project on STM32F103 used STM32CubeMX, and Enabled its CAN mastor mode, and Enabled CAN's all interrupts(RX,TX,ERROR). Then make a SIMULINK model link to the ioc file, and place a CAN_IT module into it. At this time, it tell me 'Configuration must be done before!', And in the CAN_IT module, the interrupts RX/TX/ERROR are unchecked and disabled.But! When I do same process on STM32F107/407/417/302/469, it is OK.Please help me. thanks.

Dear all,I am trying to program STM32f072 microcontroller with simulink and i use Matlab R2013b and MAT Target 5.1.0 when i have used stm_config block to configure hardware target i got a problem that i can not set the block parameters.I herewith attached the evidence for your reference.

Dear community!Is there an instruction on how to integrate ready-made libraries into a Simulink for STM32 MAT as it is done for Arduino? For example, to work with an SD card using SDIO or SPI? There should be a way to work with the SDIO or SPI SD card without manually prescribing the initialization algorithm and the FAT management system. It is much easier to use a ready-made C / C ++ library for this. Can integration be done with the help of a Simulink S-function block?

I have this code in Arduino,but i need translate in hall library,could have i the translate?​Tested code:Code: [Select]​#include "SPI.h" unsigned int result = 0; unsigned int result1 = 0; unsigned int result2 = 0;​void setup (){Serial.begin(9600);SPI.begin();SPI.setBitOrder(MSBFIRST);}​void loop () {​digitalWrite(SS, LOW);​ //Reading 16 bit frame (the first half of 16-bit SPI transfer) result[0]= SPI.transfer(0b00000000); result[1]=SPI.transfer(0b000000); digitalWrite(SS, HIGH);  Thanks!​

CM4 configuration for the project STM32Cube_FW_H7_V1.5.0\Projects\STM32H747I-DISCO\Examples\GPIO\GPIO_EXTI\EWARM generates error The stack pointer for stack 'CSTACK' (currently 0xA05F0001) is outside the stack range (0x10000018 to 0x10000418) when try to debug the Cortex-M4.

Kindly share the code for Keil.

Hello All,I have used STM32F103RBTx Dev board previously on Windows (windows 7 Professional) Platform with Kiel uVision4 IDE and STM32CubeMX 4.24 tool.I had also build an example code which used PWM, GPIO, UART and SPI peripherals and it worked properly.As per requirement now i have to use Ubuntu 14.04 Linux based system with Atollic TrueSTUDIO® for STM32, Version: 9.2.0 and STM32 CubeMX version 5.3.0.I have Installed Atollic IDE and STM32CubeMX and also installed Embedded Software package for STM32F in CubeMx, reference Image attached belowAfter this by refering the video on the link given below i tried to build the blinky example code,https://www.youtube.com/watch?v=6RqUkFIeN6w&t=470sHowever I was able generate the code but when i compile the code i am getting error mention in the attached screen shoot.So is there any Dev board specific package installation to be done so that it finds the HAL Library path which is mentioned in error messageOr, I am missing out on something while

Hi all,I working on parallel synchronous transmission. I am using LPTIM2 as clock (PWM) and GPIOE as data bus. It is working with BDMA but here is 50ns offset between Clock and data no matter what frequency I setup. Please see pictures below 84kHz and 8MHz.  So I would like to eliminate 50ns offset between clock and data.I trying to make synchronisation at falling edge of CLK. And my goal is reach 16MHz.It is even possible with STM32H7 ?Current configuration STM32H743, 400MHz, SW4STM32, HALThank youMichal

We are using STM32F4079I-EVAL board and are new to it. We have checked the examples and demo apps in --> STM32Cube_FW_F4_V1.24.0 But unable to find anything that could help us to print logs.

i want develop using RTE_device.h classic configuration .So how can I fix this one .

I am working on IAP boot-loader where the user application store either in 2 sector in which update comes in other sector respect to the current sector. So I need to build user app memory independent but I don't know how to do it. Could someone help?

I am working with a STM32F407ZGT, I have downloaded demo code from the ST website containing different projects related to ethernet the file is called "en.stsw-stm32070" (ATTACHED). I am using Atolic TrueSTUDIO and I am having the issue that any changes made to the code have affect only in the edited file and it isn’t recognized by other files which include the edited file. I have used the “httpserver�? project and edited the “main.h�? file, the changes seems to have affect in the same file but are not recognised by other files, is there any help I could get from you to solve this issue?
