Hi is it possible to use a 14.7456MHz crystal with a STM32G031 (LQFP32). If I'm right it is not possible at the data sheet, there is no OSC_OUT for this package. Or is the option missing in the data sheet? We need this crystal for an IO-Link application.Br Maurice

Also I got the Error seen on the picture. I am a newbie to the topic and just want to get the kit startet. Any Suggestions

Hi, recently we purchased LD39200PU33R Fixed voltage circuit.i have to give 5v input voltage but i get 4.7V..that datasheet mentioned 3.3V..expected voltage i didn't get..

Hi,I'm working on a STM32L072 project, with an environment composed of arm-none-eabi-gcc compiler version 10-2020-q4, make and Eclipse IDE.I'm having trouble with a hardfault occuring in libc_init_array function call in startup file. Using disassembly in debug mode, I can see that the instruction that causes the issue is "blx r3" which jumps at address 0x0. At this point, the r3 register value is 0x0.According to ARM documentation, the blx instruction exchange the instruction set. I've then tried to write the libc_init_array function in my project asI thought maybe the external libc_init_array function used was not compiled with the right instruction set. Though this does not fix my problem, I am able to see that the jump at 0x0 address is due to callback call using an array of callback named "__init_array_start" that is initialized with 0x0, in the libc_init_array function.I'm now stuck at this point and don't really know where to look next.I've looked into the linker file and the map

I've looked in many places and haven't found a definitive answer yet. The reference manual simply states that reading the GPIO port input register returns the value of the associated pins. Does that mean that an external device has to be driving the GPIO pin at that time? What if no external device is driving the GPIO pin at that time (i.e. all candidate drivers are in hi-z) but have previously driven a value onto the GPIO pin. For what it's worth I am planning to use the STM32H725 (CORDIC + FMAC + MDMA -- very cool!)

I have read the accelerometer data using(H3LIS100DL) sensor then I got some negative value x=-3, y=-2, z=-1. I used these register OUT_X(29h), OUT_Y(2Bh), OUT_Z(2Dh). My question is how to verify these accelerometer X, Y, Z data is correct or not?

I have a project on stm32f4 with SPL library(standard peripheral library), so I want to switch to stm32f7 mcu and now i want to know is there any SPL library for stm32f7. i couldn't switch to hal library so is stm has any life time code for it or not?

I ask this method because I am familiar with Arduino, and I am a beginner in using Arm as embedded systems and also for my research

I'm working with the STM32F7 dual-core capability for the first time. Using NUCLEO-H745ZI-Q, DfuSe Demo v3.0.6, DFU File Manager v3.0.6I have one program for the CM7 core and another for the CM4 core. I can enter the system bootloader by applying 3.3V to BT0 on my NUCLEO-H745ZI-Q board. Here's my testing:I can load and run both programs on each core with the onboard ST-LINKI can load and run the CM7 program by itself with DFU.I cannot load and run the CM4 program by itself with DFU. DfuSe doesn't even look to start.I cannot load and run a DFU file containing the CM4 and CM7 program. It stalls halfway through the erase. To have both BIN files in one DFU file, the DFU File Manager allows multiple BIN files under the BIN file button. The CM7 is placed at address 0x08000000 and the CM4 is placed at 0x08100000. This matches the memory map file for my ST-LINK, which is working.I'm curious how to utilize the DFU to program for both cores. What am I missing? Can you point me to any threads or

I have setup UART1 clocked with HSI clock, with drivers version 1.16Which led to incorrect output on the line.Same code with drivers version 1.14 worked completely fine. See picture.Turns out HSI trimming value is not correct in clock setupRCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0}; RCC_PeriphCLKInitTypeDef PeriphClkInit = {0};   /** Initializes the CPU, AHB and APB busses clocks */ RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI; RCC_OscInitStruct.HSIState = RCC_HSI_ON; /* RCC_HSICALIBRATION_DEFAULT seems to be wrong */ RCC_OscInitStruct.HSICalibrationValue = RCC_HSICALIBRATION_DEFAULT; RCC_OscInitStruct.PLL.PLLState = RCC_PLL_NONE; if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK) { Error_Handler(); } /** Initializes the CPU, AHB and APB busses clocks */in different versions of drivers it is hardcoded to different value:v 1.14 - 0x10uv 1.16 - 0x40uAlso, when I entered debug mode and checked actual value

I created STM IDE project from the scratch. I'm using STM32H742Zi Nucleo board. When I configure the debugger I have only two options , all to them are ST-LINK debugger. See attached picture.This features worked flawlessly in Atollic True Studio.The project is available on githubhttps://github.com/mirtcho/ADS1256Thanks in advance

In the STM32H7 Example project, the CubeMx .ioc file is missing.Does CubeMx support STM32H7?Could anyone please tell me about the above?

Hi guys,I hope you can help me with this one:In approximately 1 out of 100 devices we have some strange behaviour which ultimately boils down to a HardFault Interrupt which triggers a Watchdog Reset.The majority of products in the field does not have this error, and the ones that does "randomly" generate it. Sometimes the stack trace is readable sometimes not, and when it is the hardfault hits at different parts of the code wihtout any obvious corelation to executed code or runtime (sometimes it hits after 2 minutes, sometimes after hours).And now the most interesting part: I tried to isolate the error and started to remove parts of my code. Currently I have a blank while(1) main loop with an alive counter without any configured or enabled interrupts and still - the hardfault hits.Do you have any ideas or clues what could cause such behaviour? I checked against all hardfault causes listed in the cortex-m0 manual but couldn't find anything promising.What I have now is only clock init (h

Hello!Is there an overview of how big the ST wireless stack is depending on the activated features?Thank you!

I want a list of TFT enabled MCU

no distributor nor STM's eshop has any STM32-device."Out of stock" or "on allocation".Why shall we waste any further development time on STM32 when there are no chips available?So, is STM32 dead?In my opinion, STM32 is dead.Currently any other experiences? Thanks.
