STM32CubeMX (MCUs)

I have to develop a product which makes use of STM32. So I was wondering if anyone makes use of STM32 CubeMX in actual product or is it just meant for prototyping.

I welcome do not regenerate main() in new CubeMX, this is very good for bootloaders. My main is also boot_main, I had to rename it everytime after project was regenerated.My suggestion is please add this functionality for every MX_*_Init function. Not generate function call already present, but I mean this for function.Eg: Somewhere I have uart initialized with baudrate loaded from flash, and I would not like to everytime replace newly generated init function with my edited one. Same applies for RTC when somebody uses backup register in MX_RTC_Initfunction.Any thoughts?

I cannot find the corresponding pins on MCU to the I2C Grove connector located on the fanout board. Currently I have an acceleromater connected to the Grove connector and would like to collect data from that. I have tried to open a new CubeMX project but cannot find the STM32L4R9I-DISCO board. I only see the STM32L4R9I-EVAL board. Please help.

When a TSC is selected, CubeMX populates two lines of the same source file in the Makefile. In other words, there are two lines of:Drivers/STM32L0xx_HAL_Driver/Src/stm32l0xx_hal_tsc.cin the Makefile created by CubeMX. To reproduce, create a new project with a L0 device, select TSC with some channel settings, and generate a Makefile project.Another bug is that CubeMX failed to update existing Makefile. To reproduce this bug, simply open up existing Makefile project file (*.ioc) and try to regenerate it.

Hello I am using CubeMX successfully for some time. Now got into strange situation when after configuration is done and trying to generate project files it actually does and reports successful generation , generated code is there but the project folder is missing .project file and .cproject file so it is impossible to open it in IDE... what can cause it?

1 The code was generated by STMCube and the MCU is stm32f030k6t62 I use 8M HSI RC as clock source .3 If I set SYSCLK to 8M (use HSI RC directly), the code can work on the board correctly 4 if I set SYSCLK to 48M (use PLLMUL). the code didn't work at all . 5 I just toggle a LED based on the generated code . 6 why did we can't use PLLMUL with STMCube?

HI, There .​I bought STM32F429I-DISC1 evaluation board.In first. I download demonstration firmware.\STM32Cube_FW_F4_V1.21.0\Projects\STM32F429I-Discovery\Demonstrations\STemWin​Run that . feel so good .ST-LINK is active and I can see USB Mass storage. but not responsed when USB USER connected(CN6).and freeze when I chooose FileViewer in top nemu.​I think 1more mass storage confirm when USB USER connect.Is it misunderstand?​I checked device manager in windows.it is host of USB.unknown device was detected.Need I get driver for that device??​Pls help me. How to resolve it or where check ? ​Thanks in advance.

Hello,CubeMX and libs version as in this topic: https://community.st.com/s/question/0D50X00009cegytSAA/l4-cubemx-package-ver-112-inconsistency?t=1534139773066The problem is that each time one regenerates the project using CubeMX, the optimization flags get reset to -Os, no matter what was set before:Debug level flags are preserved correctly. @Imen DAHMEN​  ?

After updating STM32Cube FW from F7 1.11.0 to 1.12.0 I encountered some problems with CDC FS on STM32F745VET. Short examples of simple code:main.h/* USER CODE BEGIN Private defines */ struct rxDataStruct { unsigned char dataReceived; uint8_t data[25]; };   extern struct rxDataStruct rxData; /* USER CODE END Private defines */usbd_cdc_if.cstatic int8_t CDC_Receive_FS(uint8_t* Buf, uint32_t *Len) { /* USER CODE BEGIN 6 */ USBD_CDC_SetRxBuffer(&hUsbDeviceFS, &Buf[0]);   for (unsigned int i = 0; i < *Len; i++) { rxData.data[i] = UserRxBufferFS[i]; } rxData.dataReceived = 1;   USBD_CDC_ReceivePacket(&hUsbDeviceFS); return (USBD_OK); /* USER CODE END 6 */ }main.c/* USER CODE BEGIN PV */ /* Private variables ---------------------------------------------------------*/   struct rxDataStruct rxData;   uint8_t REPLY_OK[4] = { 0xFF, 0x04, 0, 0 };

Hi,I have an unpleasant experience with NEW CubeMX 4.26.1. I had project for Cube in veriosn 4.20 or something like that. But unfortunately, when I updated the CubeMX to vesrion 4.26.1. Then I opened my project in it, and then after generating code in CubeMX the all my own files (***.c, ***.h) in the projects was deleted. No waring, nothing. All my files in my project for TrueSTUDIO are gone.Is there any solution? When the new fixed version of Cube will be on ready?Thanks, Jan.

Previously posted to the STM32 "community", but it appears this might be the more appropriate forum...?Perhaps I'm a bit thick and am missing something, but it appears that in the most recent versions of the STM32L4 HAL that FIFO support has been added in the USART extension driver. Specifically, there are functions defined:HAL_USARTEx_EnableFifoMode()HAL_USARTEx_DisableFifoMode()HAL_USARTEx_SetTxFifoThreshold()HAL_USARTEx_SetRxFifoThreshold()HAL_USARTEx_RxFifoFullCallback()HAL_USARTEx_TxFifoEmptyCallback()However, the documentation for these is minimal at best, and there are "#if defined(USART_CR1_FIFOEN)" statements throughout the driver code, and I can find no definition for USART_CR1_FIFOEN anywhere, or how this should be defined. Can anyone shed some light on whether this USART FIFO functionality is supported, and how I can get it working?

Posted on June 04, 2018 at 07:10I'm trying to generate some working code for a STM32F746-DISCO board using STM32CubeMX Rev 4.25.1What I was expecting to happen is that I select all the peripherals, configure them how I'd like them to work, hit 'generate code' and it would make me a project that had everything initialised properly, ready to go. I could then write my application to use the peripherals as required.So I go 'new project', select the STM32F746-DISCO board, say 'yes' to 'Initialise all peripherals with their default mode', disable camera, sound, ethernet and USB (I don't need them and it chokes at startup if the Ethernet isn't plugged in), generate code for EWARM and open the project in IAR. I then turn off compiler optimisation and change the debugger to J-Link (I reflashed the board with the Segger firmware because the ST/Link one wouldn't work properly).I then program the board and let it run - the screen starts off

STM32CubeMX Version: 4.26.1Bug description: The project files keep being moved in to the TrueSTUDIO folder as the UnderRoot option is changing by itself when opening the project settings window.Can be reproduced with the following steps:Open a project where the UnderRoot option has been set to trueOpen the project->settings windowCancel the windowFile->Save ProjectCheck the .ioc project file for changes No changes occur as expectedOpen the project->settings windowCancel the windowFile->Save ProjectCheck the .ioc project file for changes UnderRoot has now changed from true to false by itself

Seems like a number of builds of cubemx in history have done this and the response from ST is that a new version fixes it. Or am i doing something wrong?If it is a reoccurring bug, perhaps you guys need to consider revising your automatic-regression-testing strategy on deliveries.

first line in function MX_SPI2_Init() LL_SPI_InitTypeDef SPI_InitStruct; is not filled with zero'sand baudrate is not set for slave mode.But in in funtion LL_SPI_Init baurate is filled in an the destruct SPI CR1 register.I have there fore init the struct to zero and then there is no moer problem LL_SPI_InitTypeDef SPI_InitStruct = {0};

Hello, i validated IN0 and IN1 for ADC1 and ADC2 in CubeMX Pinout tab; in configuration tab, the button ADC and ADC2 are inactive : i can't configure the ADCAny idea to solve this ?Thanks for any supportRegardsNB : it works well for STM32F3 devices...

Hi,I'm trying to use the current CubeMX to generate USB CDC code for SMT32F303RE. The generated code doesn't connect to my Windows 10 machine. The device not even appear.I did almost the same on STM32F411RE and STM32F407VG, both works perfectly.Looking into the code I realized that the GPIO initialization code is not generated, I added it, but still no success.I'm using the following components:CubeMX v4.26.1STM32F3 Series driver package v1.10.0STM32F4 Serias driver package v1.21.0Atollic TrueStudio v9.0.1ThanksZoltan

Posted on January 15, 2017 at 23:06Hello I am reporting a bug generated by cubemx in the file stm32f4xx_hal_sd.c.Please read the thread: https://community.st.com/0D50X00009XkfctSAB , https://community.st.com/0D50X00009XkeRpSAJ Here is the thing:1. Pack version: STM32Cube_FW_F4_V1.13.0, Cubemx 4.16.1. The uSD card I tested is 1GB made in japan.2. The lib for microSD and file is generated by cubemx wizard.3. I tested the microSD on the chip STM32F405RGT6 . . 4. The problem I confronted is that initialization of sd card always fails, but everything goes through smoothly if I reset the chip(via nrst). Weird? Make the story short. Initialization of SD card fails in the function: SD_PowerON(SD_Ha

Posted on December 08, 2017 at 05:49Pretty sure this is a codegen bug in CubeMX v4.23.0 with latest libraries.To reproduce: start a fresh project, select STM32F103, enable USB, choose Custom HID Device, press Generate. When run, this generates a hard fault.We see that the 'user string' feature is enabled by default:C:\Temp\Test\Inc\usbd_conf.h:83 &sharpdefine USBD_SUPPORT_USER_STRING 1And this results in an additional callback added to the end of USBD_ClassTypeDef:C:\Temp\Test\Middlewares\ST\STM32_USB_Device_Library\Core\Inc\usbd_def.h: 177 uint8_t *(*GetOtherSpeedConfigDescriptor)(uint16_t *length); 178 uint8_t *(*GetDeviceQualifierDescriptor)(uint16_t *length); 179: &sharpif (USBD_SUPPORT_USER_STRING == 1) 180 uint8_t *(*GetUsrStrDescriptor)(struct _USBD_HandleTypeDef *pdev ,uint8_t index, uint16_t *length); 181 &sharpendif This is

My hardware developer gave me the attached .loc file which includes DMA enablement. I select Code Generation and then try to generate for AC6 System Workbench, and it hangs almost immediately in the code generation. If I try to create even a simple STM32.loc file (for the Nucleo STM32L073RZ eval board) with DMA enabled and it fails. It seems that it fails whenever the dma is enabled? What is going on?

Hi all,I'm using STM32CubeMX along with Atollic TrueSTUDIO and experiences a small issue.Whenever I generate code from CubeMX, the debug configuration of my TrueSTUDIO project gets modified/overwritten to use JTAG as opposed to SWD (which I would like to use).This means that whenever a generate new code, I need to manually go in and correct the interface.Do you know if there a solution to this (maybe a CubeMX setting that I'm missing)?/ Andreas

Hello, I made a customboard using STM32f217VET microcontroller and KSZ8081 PHY (builtin pull-up resistors for TXP TXM and RXP RXM). I Configured my board to use MII mode, anda I used a 25MHz oscillator to do so. As you can see it is missing a 1k pull-up resistor for the INTRP pin, but I have already fixed this by wiring up a resistor in pin 32. Now it works accordingly.As of this moment I have tried 3 approaches to make this work (it is connected to a point that supports DHCP and is always assigned the same IP).I initially tried to configure freeRTOS + lwIP with a custom PHY, since DP83843 was the only one on the list in cubeMX. With this I was never even able to get a link is up when reading the registers and auto-negotiation never completed. Not to mention that I was unable to receive any data from pins RXD0..RXD3 , even though I can see the differential input data in the RJ45 pins when I ping my board and I can see a 25MHz clock in

Hi, some questions about the HAL USB-CDC (USB_FS) implementation. I use a STM32F405 with TrueStudio and CubeMX (for code generation) and Win10. I changed, as suggested from ST, the heap (0x1000) and stack (0x800) size. The USB CDC user Buffers are 128 bytes each and the USBD_MAX_STR_DESC_SIZ Buffer is 256 bytes.Questions to begin with:What is the use case for USBD_MAX_STR_DESC_SIZ Buffer?Do we store the configured USB-descriptors in this buffer? see https://www.beyondlogic.org/usbnutshell/usb5.shtml#DeviceDescriptorsHow big should this Buffer be (minimal)?My problem:When i change the Buffersize (USBD_MAX_STR_DESC_SIZ) to lower values than 256 or higher values than 512 bytes the USB device is recognized by the OS (WIN10) but i cannot connect to the device/com-port via HTerm or an

STM32CubeMX Version 4.26.1 (STM32Cube V1.0) which is the most recent version (as of late August 2018) available for download. It includes FreeRTOS version 9.0 as middleware. Will ST do updates to provide FreeRTOS updates such as FreeRTOS version 10.0? Or is a STM32CubeMX user expected to download the source code from https://www.freertos.org/FreeRTOS-V10.html and build the newer library(ies)?

I have been working with a USB custom HID device trying to get it to work on Android but I'm failing miserably... It looks like Android keeps re-detecting the device every so many hundreds of milliseconds. Here is the dmesg output:[ 735.380289] input: Motus Nova Hand Peripheral as /devices/platform/fe3a0000.usb/usb6/6-1/6-1:1.0/0003:0483:C0ED.1A2C/input/input6703 [ 735.434904] hid-generic 0003:0483:C0ED.1A2C: input: USB HID v1.11 Joystick [Motus Nova Hand Peripheral] on usb-fe3a0000.usb-1/input0 [ 735.484185] input: Motus Nova Hand Peripheral as /devices/platform/fe3a0000.usb/usb6/6-1/6-1:1.0/0003:0483:C0ED.1A2D/input/input6704 [ 735.545130] hid-generic 0003:0483:C0ED.1A2D: input: USB HID v1.11 Joystick [Motus Nova Hand Peripheral] on usb-fe3a0000.usb-1/input0 [ 735.612361] input: Motus Nova Hand Peripheral as /devices/platform/fe3a0000.usb/usb6/6-1/6-1:1.0/0003:0483:C0ED.1A2E/input/input6705 [ 735.681471] hid-generic 0003:0483:C0ED.1A2E: input: USB HID v1.11 J
