STM32CubeIDE (MCUs)

I am currently working on a project involving two STM32F446RE microcontrollers, each connected to a CJMCU-2551 MCP2551 CAN Protocol Controller High-speed Interface Module. The setup is intended to facilitate CAN communication between the two microcontrollers.Problem:The STM32F446RE configured as the transmitter is successfully sending data.However, the second STM32F446RE, intended to receive the data, is not receiving any communication.Additionally, I have observed that the MCP2551 module connected to the transmitting STM32F446RE is showing equal voltage levels on both the CANH and CANL pins.Request for Assistance:Could this issue be related to the CAN bus itself, or might it be a problem with the software configuration?What steps can I take to diagnose and resolve this issue?Any insights or suggestions would be greatly appreciated.

I want to use ThreadX and a Command-Line called letter-shell with CubeIDE, used a uart lib(lwrb) but changed it to HAL, but it will crash when send an costum command. Send string is "func 123 "hello word"".Here are a few of the ways I've tried: First, it works well without ThreadX when using CubeIDE, still used a uart lib(lwrb) but changed it to HAL. Here is the repository(link).Second, I tried porting the program to MDK, everything is same but compiler. The project of CubeIDE and MDK are both in this repository(link). Third, I increased the heap and stack when using CubeIDE and ThreadX, it does not work./* Entry Point */ ENTRY(Reset_Handler) /* Highest address of the user mode stack */ _estack = ORIGIN(RAM) + LENGTH(RAM); /* end of RAM */ /* Generate a link error if heap and stack don't fit into RAM */ _Min_Heap_Size = 0x800; /* required amount of heap */ _Min_Stack_Size = 0x1000; /* required amount of stack */ It's very strange, the question is not letter-sh

Mr./Ms. Forum,I have the following system components:STM32CubeIDE Version 1.11.0Segger j-link PLUS Compact debug probe Version 11.0target hardware - custom pcb with an STM32U585CIT6 microcontrollerI can't load code into my target hardware. I have included a bunch of helpful screenshots and a capture of the messaging (Segger_JTAG.txt) between the Segger and target hardware JTAG port. The log says 'Could not connect to target', but I could  see duplex traffic between the Segger and target. Google and forum searches have been useless.Can anyone out there explain the problem and provide a solution?Where can I find the Segger j-link message protocol?  

HAL_UART_Receive and HAL_UART_Receive_IT contain a bug. To reproduce (I use STM32L412KB nucleo 32 for this):Connect a terminal emulator to the ST-LINK as serial port.Configure that serial port in CubeIDE if default not chosen.Use for example the following code:HAL_StatusTypeDef uhst = HAL_UART_Receive (&huart2, uart_buffer, 1, 1);if (uhst == HAL_OK) { /* store the single byte in a larger buffer */ }If one runs the code, there seems to be no issue.Put a breakpoint in the function that stores the UART data.Type 1 char in the terminal: the debugger kicks in. The debugger stops the core but not the UART. Type a number of chars in the terminal, enough to cause UART overrun condition.Resume the software from the breakpoint. Whatever you type from now in the terminal emulator, HAL will never report UART data available. The easiest solution is to put a receiver timeout and when it happens call__HAL_UART_CLEAR_OREFLAG(&huart2);but this isn't a clean way. HAL implemenation should clear t

Why is this error very hard to find?I cannot find the exact reason this is happening?I have project say named Project_1 that works properly (This is created using TouchGFX on STM32H735G- DK board)now if i copy this project manually and paste it in another dir and open that in Stm32cubeide and try buildingbuilding works once for second time the error occursI also tried copying my project codes after crteating a new project using touchgfx instead of just copying existing projectstill same errorNote that i have my own files in separate folders that i added in all the projectsafter cleaning the project - 1st time build ok - 2nd time same errorI also tried copy pasting the main.d file from my Project_1 into the new project but same errorSTM32CubeIDEVersion: 1.16.0Build: 21983_20240628_1741 (UTC) STM32CubeMX - STM32 Device Configuration ToolVersion: 6.12.0-RC9Build: 20240628-1431 (UTC) 

Hi to all comunity I've written the function below to reiceve interrupt from as7058 and LSM6DSOXTR but I have many and long periods that I received interrupts from as7058 only.How can I balance the receiving between them?void HAL_GPIO_EXTI_Rising_Callback(uint16_t GPIO_Pin) { if (AS7058_INT_Pin == GPIO_Pin) {/* Handle AS7058 INT pin interrupt*/extern void _as7058_int_pin_interrupt_callback(void);_as7058_int_pin_interrupt_callback();return;} if (iNEMO_INT1_Pin == GPIO_Pin) {/* Handle here LSM6DSOXTR INT1 pin interrupt*/return;}} 

I have a problem with this part of the code that involves the HAL erase function. I want to calculate the sector address from the block number i, but after execution, I encounter an error during debugging: "target ST-LINK error (DEV_TARGET_NOT_HALTED)."  any one can you give me a solution please  

I have problems with remote debugging of an STM32L432 device from STM cube ide ver 1.9 on arch linux.gI can connect and debug with cube with the target directly connected.When i connect to a remote raspberry with the same tarrgeti i get an error: "Could not verify ST device".In the gdb log in stmcube i get the following: 877,561 &"monitor ReadAPEx 0x0 0xF8\n"877,566 @"invalid command name \"ReadAPEx\"\n"877,567 &"Protocol error with Rcmd\n"877,567 24^error,msg="Protocol error with Rcmd"it seems ReadAPEx command is unavalible.Debugging with cli-gdb seem to work, but has no ReadAPEx instruction.I can connect with an old version of stmcube on windows platform, but this version does not seem to send the ReadAPEx command.I have tried openocd version 0.12 and pyocd 0.36 on the raspberry and result is the same with both servers.st-util 1.7 is not working, neither with new or old cube. Anyone experienced the same thing? I found some thread about mod_cmd_extended.cfg but this

Is there a guide of how to share a STM32CubeIDE project in github for collaboration?I tried this for a modified version of the STM32 demo program "FatFs_USBDisk" - to extend/enhance it in a team.When I adopt the base demo program in github, and someone else clones it, then it can't be compiled.

I want to use the FPU in an ISR. Will I have context switching issues or i have to specifically make changes in the System_stmxx.c if i am using code generated from CubeIDE.Do i need to setup these registers explicitly or it is handled by CubeIDE by default? (i didn't found these bits explicitly setup in System_stmxxx.c ) FPU->FPCCR |= (FPU_FPCCR_ASPEN_Msk | FPU_FPCCR_LSPEN_Msk);This code sets the ASPEN (Automatic State Preservation Enable) and LSPEN (Lazy State Preservation Enable) bits, ensuring that the FPU context is handled appropriately during interrupts.MCU: STM32H723ZGT6CubeIDE Ver: 1.16.0

I am working on STM32G474 and I need to convert float to q1.31.Is there any chance the compiler use command vcvt.f32.s32 s15, s15, #31 in language C?I need this for CORDIC. 

I want to design an mppt solar charge controller my design is ground isolated and a common positive shared between input and output the problem is I want to take two samples twice periodically on ADC Channel 3  one on rising edge (Output volt) of timer PWM output and other on falling edge( input volt). i set the timer to frequency of 10khz to switch the mosfets and trigger the adc as well but both the values are same. it should be different from each other i mean adcBuffer[1] and adcBuffer[6]. the oscilloscope is attached channel 1 in Digital oscilloscope is PWM and the channel 2 is toggle led when the conversion is completed.here is the complete code   uint16_t adcBuffer[10]; /* ADC CALIBRATION */HAL_ADCEx_Calibration_Start(&hadc);HAL_TIM_PWM_Start(&htim1, TIM_CHANNEL_1);// HAL_ADC_Start_IT(&hadc);HAL_ADC_Start_DMA(&hadc, (uint32_t*)&adcBuffer, 10);static void MX_ADC_Init(void){ADC_ChannelConfTypeDef sConfig = {0};hadc.Instance = ADC1;hadc.

Hello everyone, I’m currently working on a project where I need to generate an ultrasonic trigger signal using the Nucleo-L432KC board and CubeIDE. I can successfully generate a constant 40 kHz signal, and I am able to control the number of cycles in each burst (8, 10, or 20 cycles) and the duration of the wait time (20 to 50 ms) between bursts based on the distance to be measured. However, I’m facing issues when trying to sweep the frequency from 38 kHz to 42 kHz. My Setup:1. Board: Nucleo-L432KC2. Development Environment: CubeIDE3. Clock Configuration: 80 MHz system clock4. Timer Configuration:•Prescaler: 0•Period: 1000 - 1 (to generate 40 kHz signal)•Output Compare Mode: Toggle•Timer instance is TIM2. The Problem: I need to sweep the frequency from 38 kHz to 42 kHz at certain intervals. To achieve this, I attempted to dynamically change the timer period. Here’s what I tried: Dynamic Period Update:•Adjust the period and pulse width in the main loop.•Use HAL f

Hi,I installed GitHub Desktop and created a local repository which resides inside a an STM32 CubeIDE project.I can modify any of the .c or .h files with any editor (notepad, notepad++, wordpad, etc) and the changes appear immediately in GitHub Desktop. But if I edit the same file/s with CubeIDE editor the changes do not appear at all on GitHub Desktop. i.e. GitHub Desktop does not show that the file (or any file) has been changed.Does anybody have any idea why?Thank you :)
