Solved

Hi CommunityHope you guys are well. I am trying to implement Bluetooth and emulated eeprom working. i have followed the ble_heartrate_eeprom_emul example and i got blue tooth and eeprom emulation working, the problem i am having is when the EEPROM emulation is implement   my function in custom_stm.c does not work properly, for example when i used any of the GPIO, the controller goes into hard fault, and current went from 0.013A to 0.150A , but as soon as i remove the eeprom emulation code , everything works perfectly. so basically i cant get my things working when there is eeprom emulation , i have tried to release the semaphore 7 in my function but still the same.  there is one more thing, in app_entry.c we have default code , check file attached, but the ble heart rate eeprom emulation tell us to put this code, check file attached,and if i put that code and generate the code again from cubemx it is removed.Assistance is appreciated!

Dear STM support team.My name is Dai. I am working at G-innovation Corporation.Now I have a project using the STM Chip(STM32F0xx).I use the STM32CubeMX (version 6.11.0) to create a project using the STM32F091VBT6 with CMIS_RTOS.this project aims to study all CMSIS-RTOS APIs.the function of the project include:- 6 thread: "idle thread" to blink an LED at 0.5Hz.              "SWI thread: is reserved.             "dut1 thread" to send counter log to the PC over UART1, "dut2 thread", "dut3 thread" and "dut4 thread" as the same "dut1 thread".             mutex to protect the "debug_printf" function.I received a "HardFault_Handler() at stm32f0xx_it.c 0x80033f4" after running it for several milliseconds.I have attached my project, the UART log, and the Debug log to this post.everybody helps me to debug and fix this bug.Regards,         

Hi everyone,I am using SPC58 MCU and Autodevkit IDE. In that I have taken Avas_Compact_Test_Application example as the base source code1. And, During execution, before integration of FreeRtos the execution was entering osalThreadDelayMilliseconds()      and coming out of it and executing further code, but after integration of FreeRtos, the execution is entering                osalThreadDelayMilliseconds() but not coming out of that API and further code is not getting executed. I have            not modified anything in the base source code expect integration of FreeRtos even though I'm facing this                  problem. Can anyone help me to come out this problem. 2. If I run base code it is working fine and if I just import FreeRtos Components without any modifications in source      code then it is building through but getting "NACK_

Hello All,I bought the NUCLEO-F446ZE board and would like to use Ethernet port but it is not soldered onto the board.Which RJ45 jack do I need to buy? Could someone provide reference to Mouser or Digikey? 

Hello,Does someone know where the Backup SRAM is located on STM32F746 (at which address)? I didn't find it in the documentation (RM0385).Thanks !

Hello, I'm trying to build a simple GUI Application with TouchGFX. And right now im trying to resize the updated area (make it bigger than needed) to get it byte aligned and because of other reasons as well.I`ve found one Person who described it here. He has overwritten the Function  void FrontendApplication::draw(Rect& rect) { // Make sure the draw area is always byte aligned rect.x -= (rect.x % 8); rect.width = ((rect.width + 7) / 8) * 8; Application::draw(rect); } like this (Copyright to Mike Norgate - see the link).I dont need exactly this function but i need to resize it at the same position in the code. So i tried to reproduced it but i got confused. I found here some mentioning of the function in touchgfx/Application.hpp but its mentioned under protected functions. So ive looked in my generated code, but in the TouchGFX/FrontendApplication.hpp there is no  function like this and i couldnt find a application.hpp as well. S

Hello, I am working on STM32H743VIT6 MCU. when I generate the code, I get MPU_Config(void) function instead of MX_GPIO_init(void) with no GPIO configuration. How can I fix this? Thank you in advance

Hi, I'm using STM32F767ZG on a development board (Fusion for STM32 V8 by Mikroelectronica).   My problem is that all ADCs will read 4095 for the first 2.3 seconds after power on. If I perform a reset on the uC, they read correctly from the first read. Also, if I power down, hold the reset button, then power on and wait ~3 second and then release the reset button, they will read fine immediately.   I suspect that the analog reference voltage on the uC on the board has an issue stabilizing quick enough, but 2.3 seconds seems waaaay too big.   Sample code: ADC_ChannelConfTypeDef sConfig = {0}; hadc1.Instance = ADC1; hadc1.Init.ClockPrescaler = ADC_CLOCK_SYNC_PCLK_DIV2; hadc1.Init.Resolution = ADC_RESOLUTION_12B; hadc1.Init.ScanConvMode = DISABLE; hadc1.Init.ContinuousConvMode = ENABLE; hadc1.Init.DiscontinuousConvMode = DISABLE; hadc1.Init.ExternalTrigConvEdge = ADC_EXTERNALTRIGCONVEDGE_NONE; hadc1.Init.ExternalTrigConv = ADC_SOFTWARE_START; hadc1.Init.DataAlign = ADC_DATA

Hello community,I am trying to show a shape (line) or text on a background a TFT parallel RGB Display. I am using the NUCLEOH7A3 board without external RAM and a 800x320 Display.Everything works fine using TouchGFX. So it is not a hardware problem or CLK. But I want to program it buy my self using other libraries.I copied the files and functions from the STM32H7B3i Discovery LCD example (stm32h7b3i_discovery_lcd.c and stm32h7b3i_discovery_lcd.h) and changed them a bit.The function UTIL_LCD_Clear() works fine (except of weired pixels on the top (line1 or 2)) but the text and the line are not shown. And if I take the function UTIL_LCD_Clear() out, the text and the line are shown but the Display background looks weird with weired pixels. (see images)   So why the text and the horizontal line are not showing after filling the screen with UTIL_LCD_Clear()?(Nevermind about the horizontal line now. It had another color, that I could see. But now because I've already made the picture

hi ,i gone through usb pcb guidelines and other forum discussion but i couldn't catch my doubt .1). Incase of Using USB Virtual Com Port D+ (PA12) & D - (PA11) pin can be directly connect with Computer USB port  without level shifter ??? During the  communication Device Class selection exactly D+ & D- is open drain or  ???----------------------------------------------------------------------------------------------------------------------------------------2.)Incase of using USB_OTG_FS in Host Only Mode   PA9 - connected to Vbus - 5V  and D+ (PA12) & D - (PA11) pin - Pendrive or Keyboard .Looks  PA9 is 5volt tolerant pin in stm32f722ze nucleo board so it's safe to keep 5v or it can be reduced to 3.3v with separate voltage divider ??? same time  keyboard supply voltage will remain as 5v only . if the Vbus sense PA9 turned to 3.3v sensing then it will affect the D+ & D- signal ???  and additionally logic

I'm using the Nucleo-C031C6 board, and I chose this (NUCLEO-C031C6) from the board selector when starting the IDE. (STM32CubeIDE v1.15). I tried switching Timebase Source (in SYS menu) from SysTick to TIM16, then when I compiled, I got this error:../Core/Inc/stm32c0xx_hal_conf.h:237:11: fatal error: stm32c0xx_hal_tim.h: No such file or directoryIt is just a bare project with no user code added.I had to switch from SysTick to TIM16 because I was trying out ThreadX.

Hi, I am working on a motor control project that need to generate 3 sine waves with 120 degree phase shift to power a 3-phase AC motor. The target MCU is an STM32G483VET6 with 100 pins, and I though that for the first step  to generate 3 PWM with phase shift shouldn't be a problem with this MCU, but it is :) Ok, so as stated in the reference manual, there are TIMx internal trigger connections, which I thought can be used for chaining 3 timers: TIM1, TIM8, TIM20 because they can generate complementary outputs as well: According to Table 252, I should have easily set this up with MX. I started to process this table, TIM1 is the first timer which can trigger TIM8 through ITR0, and TIM8 can trigger TIM20 through ITR5.  TIM1 setup:- Channel 1 -> PWM Generation CH1 CH1N- Channel 2 -> Output Compare No Output- Counter Settings:   - Prescaler: 47 (Because I am using 48MHz clock from HSI)   - Counter Period: 9999 (100 Hz, nothing fancy)- T

HiI'm trying to understand how to configure the hal/peripheral to evaluate the CRC32 MPEG2 over a block of datas.I'm comparing the result with this site where as input I've used the vector 0x01, 0x01. Expected result is 0xD66FB816https://crccalc.com/?crc=0x01,0x01&method=crc32&datatype=hex&outtype=0  I've configured the hal in the following wayhcrc.Instance = CRC;hcrc.Init.DefaultPolynomialUse = DEFAULT_POLYNOMIAL_DISABLE;hcrc.Init.GeneratingPolynomial = 0x04C11DB7;hcrc.Init.DefaultInitValueUse = DEFAULT_INIT_VALUE_DISABLE;hcrc.Init.InitValue = 0xFFFFFFFF;hcrc.Init.CRCLength=CRC_POLYLENGTH_32B;hcrc.Init.InputDataInversionMode = CRC_INPUTDATA_INVERSION_NONE;hcrc.Init.OutputDataInversionMode = CRC_OUTPUTDATA_INVERSION_DISABLE;hcrc.InputDataFormat = CRC_INPUTDATA_FORMAT_BYTES; NOTE that poly and init value that I've set are equal to the default values but I get this result0xeec8fd24 Does someone has an idea how to configure this peripheral to get

I tried to show text via textArea, i put some string into translation field, i see the string in designer but when i ran it the text is not present. I tried similar thing with digital clock with same result. I tried define own typographies with or without wildccards and non generated texts but all with the same result. I tried it on real hardware, other things like images and buttons are visible but the text in textArea not. Should i call some method for rest of init textArea?

Hello,Sorry if i'm asking a dumb question or if someone already ask it, but I have some problem pinging my NUCLEO-H723ZG using Ethernet and lwIP without FreeRTOS.I already tried the tutorial to create a project with Ethernet and lwIP step by step , it didn't turn out well (I have some question about this tutorial on memory layout of the DMA Descriptors) and I couldn't ping over the MCU.I also tried the github example provided on the same article and more precisely I tried the STM32H723_Nucleo_ETH example. It worked very well, but it use FreeRTOS which I do not want to use for now.I tried to create a project from the .IOC of STM32H723_Nucleo_ETH example, I modified it to disable FreeRTOS and disable ETH global interruption. It didn't work (I still couldn't ping over the MCU).So I have multiple questions :Does lwIP must be used with FreeRTOS on the MCU of the H7 series or other kind of RTOS ? (I already use lwIP without a RTOS on a NUCLEO-F429ZI and I didn't have any issue with it).On th

Looking at the FDCAN peripheral application note (AN5348), I don't see any mention of using the DMA. I'm interested in transmitting 30 8-byte messages every second via Classic-Can 2.0.   Since the peripheral's FIFO isn't that deep, I was thinking of either using the TX FIFO empty interrupt to trigger more pushing, OR (preferably)..have the DMA push the data to the FDCAN peripheral automatically without CPU intervention. Does the DMA controller support memory to FDCAN, or are there registers that the FDCAN needs configured for every transfer?

Hello All,I would like some clarification as to how I can verify if the internal clock HSI will run based on what external power input is given.I had originally found that running the board on external 3.3 v will not allow the HSI clock to be used, and the clocks would only run if I attached USB power. If I removed USB power from the board after power it briefly the clocks would still run even at 3.3 v external power. From this post https://community.st.com/t5/stm32-mcus-boards-and-hardware/problem-with-3-3v-external-power-delivery-to-my-board/m-p/88516/highlight/true#M14341 I understand that the ST-link needs to be able on some nucleo board to run the HSI clock.From the NUCLEO-L031K6 board documentation I found this table:this shows that using a 5 v in will not run the ST Link, however reading further the following section is talked about:The section doesn't include "running clocks", but I am not sure if the document would explicitly include "running clocks" since it might be an

The file stm32f4xx_hal_def.h refers to stm32f4xx.h I can find this file in several Github repositories, but which is the official source for this file ?

Hello All, I Hope you are well.I am facing a problem that I spent A LOT of time on. I designed a custom board featuring the STM32F405RGT6 but i cannot connect to it at all.. I will attach the schematic and the board's pictures below. (The schematic is a PDF where I attached the sheet of the MCU's circuitry only there are other sheets for other parts of the board) Things to mention:1- I've assembled the board myself (But i checked the connectivity and voltages on the necessary nodes by a multimeter and i tested on the chip's pins not on the PCB pads and got the following:-VDD on all VDD pins are 3.31V (measured directly on the pins)-VDDA is also supplied by the same source with around 3.31V (measured directly on the pins)-Vcap1 and Vcap2 are both 1.26V (measured on the the two Caps of 2u2 value)-Reset Pin is 3.31V)2- I got suspicious about the SWD pinout that i did so i used an adapter and a Nucleo board's ST-Link to connect to my board where I measured the resistance between the S

I am having issues using sprintf in an application on a STM32H743 using Azure RTOS.  The function works correctly the first time it is used to convert a float to a string but after the first use, it inserts garbage characters where the decimal point should be while the digits are as expected.  The garbage characters continue to show up on subsequent calls to the routine where the sprintf is used and show up in other routines that use sprintf.  The garbage characters are always the same and only appear for float values that have digits to the right of the decimal point.  An example is when printing the conversion for the internal battery measurement which comes out as ...MCU Bat : 3.15 V on the first pass, then comes out as ...MCU Bat : 3"KOq@=xZ15 V on the second pass.  It is repeatable.  The format string is ...MCU Bat : %.2f V\r.  Changing the format string does not seem to effect the result.I have gone over numerous posts regarding s

Hi, I have an application where I need to send send signals to 8 stepper drivers on my STM32F407 Discovery board. Each stepper driver requires an independent PULSE, DIRECTION, and SLEEP signal. DIRECTION and SLEEP are trivial GPIOs high/low. I have used timers in the past to drive the PULSE pins for these stepper drivers with success.I am wondering if I can control all 8 independent PULSE pins with a single board. There are 8 timers on the STM32F4 . TIM2, TIM5 TIM9 and TIM14 are General-purpose timers and TIM1 and TIM8 are Advanced-control timers. I am confident I can drive 6 independent PULSE signals with these 6 timers. TIM6 and TIM7 are basic timers without input/output functionality. Is there is a way to drive two other pins with the basic timers 6 and 7 or is there another way to get up to 8 independent PULSE signals?

I am learning stm32f407ve, And I am facing problem in building the project.GPIO_Init( ) and GPIO_ReadFromInputPin( ) both functions are defined in the same files and declared in same files but when i build the project . I get Error for GPIO_ReadFromInputPin( ) and not for GPIO_Init( ) , how is this possible ? 

Hello,I am using a STM32MP157C development board from Myirtech and trying to interface the board with a CAN device.I am able to bring up the can0 interface.
