STM32 MCUs

Split from https://community.st.com/t5/stm32cubeide-mcus/problem-with-file-ioc-quot-not-a-valid-ioc-file-quot/td-p/791325 as this is a new questionBut now, I have another question. The file I use is one of the example on stm32G431RB "DAC_SignalGeneration2" and for this example, the output frequency on Oscillo is 1kHz but for my use, I want to have high frequency for sinusoidal signal on oscilloscope. I try many issu but i don't have what i want. For example, I calculated PSC et ARR corresponding to my frequency i want or double the number of step in tab sinewave or do (programmed a specific tab sinwave at the frequency i want but i stil don't have good result on oscilloscope. And i don't understand the specific roles of each timer (TIM2 & TIM6) in th

Project: samples/basic/blinky board: stm32h735g_disco I am using the latest Zephyr 4.1 If have a simple project `sample/basic/blinky`. Using the west command to compile the project, flash the board, debug the board with OpenOCD protocol. Everytime I used the debugger (dbg), I am able to step by step the project until I reach the k_msSeep() function. A friend of mine help me to debug it and we were able find that the system breaks as indicated in the picture below. If I don't use the debugger DBG, then the software does not crash... It just work.  

The only api that i found related to angle in observer + pll (sensorless) mode is MC_GetElAngledppMotor1 ...Can i do something with this thing ..?@GMA  

Posted on May 23, 2018 at 02:26Hi,I tested the example FDCAN_Com_IT. FDCAN configuration copied below.When I transmit a frame from another board with the ID different from 0x111, the message is received in the 'HAL_FDCAN_RxFifo0Callback' function anyway. I suppose that this configuration should only accept frames with the ID = 0x111.I did verify that the FDCAN1->GFC = 0x00. When I forced FDCAN1->GFC = 0x3F inside the  'HAL_FDCAN_Init ' function, I could receive frames only with the ID = 0x111.Is that a bug in the HAL?  Or this configuration is wrong?How can I change the configuration below for the extended ID = 0x011111111 and with the mask to receive only this ID?Ari. hfdcan.Instance = FDCANx; hfdcan.Init.FrameFormat = FDCAN_FRAME_FD_BRS; hfdcan.Init.Mode = FDCAN_MODE_NORMAL; hfdcan.Init.AutoRetransmission =

Posted on June 29, 2017 at 21:08Hello Guys , I am  writing a programme in STM32F302R8 and  trying to interface  c8855m OEM Print Cartridge Driver through SPI protocol. I have to transmit 8 bit data in DCLK of Controller but it transmit 16 bit. Could you give me idea How can I generate 8 bit data in DCLK line .

Hello, I was reading the RCM Regular Conversion Manager. It states that it is forbidden to add new injected channel on ADCs using current sensing. However, they do give an option to use regular conversion. But in my case, I need to read a sensor at the  same time of the current sensing. Since we have two ADCs used for current sensing since I am using STEVAL-PTOOL4A, is it possible to add this channel as injected one on both ADCs ? and what is the issue in adding it to one of the ADC as injected channel? I don't get what could be the issue? Thank you.

Moved from MPUs forum: STM32C0 is an MCU - not an MPU. Hi, I am not sure if STM32 cryptographic firmware library can run on STM32C071 because this microcontroller does not have embedded Crypto (Hardware) ?   Thanks   Gregory Saint-Jean

Hello all, for STM32H757xI in package WLCSP156, I didn't find a clear explanation about connecting capacitors for power supply. According to the schematic from STM32H757xI  kit, it looks like all VDD_MCU pins need to connect 100 nf capacitors, Only in my case, I can do that, since not enough place on the PCBI wanted to ask, does it

Hello, I have a STM32WBA55G-DK1 board, and i'm trying to build the example code for the Unicast server (BLE_Audio_TMAP_Central example project). I'm importing it using the GUI (new project, example, then i select the example).  I haven't modified anything in the code, but when i try to build it, i have the following error (see image bellow)  I tried to compile another example code (using the same steps as with the one giving errors), and it is working as intended. Can you help me please? Thank you.

NRST configured as GPIO to output MCO clock.In rare cases after power-on, the MCO clock is not output, although the program runs normally (e.g., printf messages are visible via UART).To increase the probability of reproducing the issue: the MCO pin is pulled up to 3.3V with only a 220Ω resistor (no other load), and power is applied rapidly using a mechanical switch. Under these conditions, the issue typically occurs within 10 attempts.The following waveforms show the MCO output in both normal and failure scenarios after MCU power-up:

Hi,I'm currently working on an application for a STM32U575VI6. It's supposed to generate an interruption every 4 minutes and 9 seconds. However, it works only when I mask the seconds, and only work with minutes. The moment I try configure both and enable them, it doesn't activates. Do you know why ? The function that configures the alarm is at line 527./* USER CODE BEGIN Header */ /** ****************************************************************************** * @file : main.c * @brief : Main program body ****************************************************************************** * @attention * * Copyright (c) 2024 STMicroelectronics. * All rights reserved. * * This software is licensed under terms that can be found in the LICENSE file * in the root directory of this software component. * If no LICENSE file comes with this software, it is provided AS-IS. * ****************************************************

I'm trying to get a USB virtial COM Port working on the STM32 Nucleo-H745ZI-Q. I've generated some minimal code to initialize the device on PA11 and PA12 and have tried connecting a four pin USB-C breakout board to wire GND, DP, DM, and U5V, as well as simply using the provided user usb port, but no luck. My configurations are as follows in the screenshots and code.My expected result is to view all COM ports connected to my computer and see this pop up, currently that is not happening.- USB set to device only on CM7- USB Clock source is from RC48- USB device set to CDC with default settingsAny help would be appreciated, I am sure I am missing something minor hereint main(void) { /* USER CODE BEGIN 1 */ /* USER CODE END 1 */ /* USER CODE BEGIN Boot_Mode_Sequence_0 */ int32_t timeout; /* USER CODE END Boot_Mode_Sequence_0 */ /* MPU Configuration-------------------------------------------------

Split from Black Pill: Debugging STM32F103RCT6 in Keil Fails to Enter main()Hi @mƎALLEm  , just about your "not genuine" statement:>- No "ARM " markingSame here on a F103 by STM , should be genuine, because its st-link on a F3-discovery board !>- There is a notch and a hole-like on one of the corners.Exactly same "problem" for many users, using the chip in a rotated position, because they took the "big" point as pin 1 indication. Exactly this is on many H743ZI and H7A3Z chips , we have here.Same on the F303 on the disco board, also " a notch and a hole-like on one " in the cornes.So maybe all these are "fakes", also on the discovery board i have here, or

I am running into a difficult bug when trying to use the SVG and vector fonts on the STM32U5G9NJH6Q that may be related to this specific variant of the chip, or to the dimensions of the RGB LCD that is being driven (or both).  The problem is that SVG images (even a single basic rectangle) end up having a "shattered" look where there are many holes/tears and random lines and shapes that almost make it look like shattered glass.  It also tends to be more prominent on the top left of the image (regardless of size).  A basic square also showed an 'X' shape like it is split into four parts by a fine line (even following rotations).  The strange thing is that animations and rotations of even large SVG images work well (despite the rendering issues).I also have an STM32U5G9J-DK2 where the SVG feature works perfectly fine.  I have built and debugged the demo 7 project in STM32CubeIDE, so my tools appear to be fine (unless this is a hardware issue with the NJH

Hi. I have worked on a project for a long time but had to swap CPU because of lack of memory. Before my device was STM32h743VG6 and I switched to STM32h743VIT6. Since i couldn´t just swap the CPU in mx without starting a new project, I swaped CPU and imported the files into a new project. It compiled and could run after some changes in the  FLASH.ld file. When generating new changes from touchgfx and programming to the flash I got memory issues. Some of them depended on path locations of files which i fixed. But one of them gave me this right before entering MemManage_HandlerNo source available for "<signal handler called>() at 0xffffffe9Somehow I can´t find the address. Any advice on what can be wrong ? 

The datasheets for the new STM32U3 MCUs (375/385) list wake-up from stop3 on SMPS in uA (current), whereas for LDO the docs list the same specs in charge (nAs).Checking the U5 datasheet and the numbers are correctly listed in nAs units. However, the values for U3 are 40-60uA, so if I add 's', it will result in fairly high figures. U5 MCU figures are ~150nAs.Please confirm that if it's 40-60uAs or 40-60nAs, or something else.Thanks.

Hello,I have an application which I would like to build on to of cubeMX generated HAL driver, but I came across strange issue that I am unable to keep RTC value on reset. Drivers part is as generated with cube using freeRTOS. system reset is triggered with `NVIC_SystemReset()`, MX_RTC_Init is as follows:/* RTC init function */ void MX_RTC_Init(void) { /* USER CODE BEGIN RTC_Init 0 */ /* USER CODE END RTC_Init 0 */ RTC_TimeTypeDef sTime = {0}; RTC_DateTypeDef sDate = {0}; RTC_AlarmTypeDef sAlarm = {0}; /* USER CODE BEGIN RTC_Init 1 */ /* USER CODE END RTC_Init 1 */ /** Initialize RTC Only */ hrtc.Instance = RTC; hrtc.Init.HourFormat = RTC_HOURFORMAT_24; hrtc.Init.AsynchPrediv = 127; hrtc.Init.SynchPrediv = 255; hrtc.Init.OutPut = RTC_OUTPUT_DISABLE; hrtc.Init.OutPutRemap = RTC_OUTPUT_REMAP_NONE; hrtc.Init.OutPutPolarity = RTC_OUTPUT_POLARITY_HIGH; hrtc.Init.OutPutType = RTC_

I try to combine the enocer mode of TIM1 with a encoder clock period measument using TIM8. The RM0456 (for U5) mentions this in the end of chapter 54.3.25 under the heading "Encoder clock output". TIM1 works fine and counts up and down according to the encoder signals. Now I want to measure very low speeds where encoder pulses happen only "now and then". My settings: * TIM1 CR2 MMS set to 0b1000: tim_trgo = Ecoder Clock Out* TIM8: Internal clock scaled down to 1Mhz (works fine, it counts as expected)* TIM8 CCMR1 CC1S set to 0b11 = TRC* TIM8 SMCR TS = 0000 = tim_itr0 = TIM1 trgoafter enabling TIM8 and TIM1 I never get an actual capture - somehow the trgo - TSC - CC1 signal chain seems not to work. Does anyone have an idea what I am missing? 

I urgently need to get USB High Speed working on USB1 of the STM32N6570-DK. I have attached the .ioc file I am using.I am able to get the GPIO_IOToggle project working on the board. I am able to put breakpoints step through the code.I am using  STM32CubeIDE version 1.18.0 (Build: 24413_20250227_1633 (UTC)).As a second step, I need ThreadX working on the board. 

Hi,I am working on STM32 MCU, in my application once I start IWDG, based on certain event I want to freeze IWDG.Since my application is running, I don't want to reboot MCU.Once event processed, I want to continue IWDG without resetting MCU.Can anyone let me know how to achieve this?Regards,Utsavi B 

Posted on December 03, 2012 at 20:42I am trying to talk to the bootloader in the STM32F100 and having some issues. I can successfully send the 0x7F and get back a 0x79 ACK. Next when i send a Get Command i don't get any response. I am sending two bytes to the micro (0x00 and 0xFF), but get no response. When i send the Get Command again, I get back a NAK. (0x1F). Is the Get command supported by this processor? -David #stm32-uart-bootloader-parity

I am trying to use the bootloader of the STM32G474QET6 with USART to program my microcontroller. I have multiple questions regarding this but the first one is more about hardware. I have found in AN2606 that for the bootloader I can only use one of three USART, as listed under :So after this info, I can use either USART1, 2 or 3 but when I look at the pins attached and at the datasheet of my microcontroller, pins for USART3 on the MCU a

I have a new STM32U5G9J-DK2 board. I have to port an application running on STM32H747I-DiSCO board.I have a big problem with setting brightness in the new board. In STM32H747I-DiSCO app I used:extern "C" { void LCD_SetBrightness(int value); }The LCD_SetBrightness() function is implemented in TouchGFXHAL.cpp file for the H7 processor. The same thing does not work with U5 processor because the TouchGFXHAL.cpp file does not contain the LCD_SetBrightness() function.So, the question is how I can set the LCD brightness in STM32U5G9J-DK2 board.I tried using the brightness control implemented in Board Support Package but calling BSP_LCD_SetBrightness(0, 50)  (50% brightne

Hi Everyone,I interfaced Nucleo F767ZI with W25Q256JV using SPI and everything was working fine. But due to time and speed requirements, now I have to shift it to QSPI. I have used example code of STM Document named "QSPI_F769_discovery_flashloader" and developed a code for QSPI. But whenever I try to run the code and write/read the memory, nothing happens. I started to run code in debug on STMCube IDE and found that when try to send command to enable write and read status register, the register value doesn't change to write enable (0x02).Always fail here and Error LED turns ON.if (HAL_QSPI_AutoPolling(&hqspi, &sCommand, &sConfig, HAL_QPSI_TIMEOUT_DEFAULT_VALUE) != HAL_OK) { HAL_GPIO_WritePin(GPIOB, GPIO_PIN_7, GPIO_PIN_SET); return QSPI_ERROR; }The Write Enable function is here.uint8_t QSPI_WriteEnable(void) { QSPI_

Hi all,For a project, I made a simple tab structure where I can put all kind of settings, The list is divided under the tabs and shown in 2 list views next to each other. In the class, I have a variable keeping track of the currently selected tab. After clicking a tab button this variable is set to the new tab. I set the number of items for the list views to the amount needed for the number of options and invalidate the list views.After doing this, if the number of items in the listview did not change, the invalidate will not trigger an updateCallback so the list items will not be updated, and instead, the old items will stay in the view. For now, I solved this by setting the number of items first to 0 and calling the invalidate function before I set the number of items to the correct amount.Is this expected behavior, or have I run into a bug here?I attached a screenshot of the view and the code to give you more of an idea of the implementationCode
