Hi,I've been trying to get I2S to work without using the HAL to get to know the MCU a bit more. I configured the Peripheral as mentioned in the reference manual, but whenever I write to the SPI->DR the status is stuck on busy.This is my init function RCC->AHB1ENR |= RCC_AHB1ENR_GPIOAEN; // enable GPIOA Port CLK; PA4 I2S1-WS; PA5 I2S1-CK; PA7 I2S1-SD GPIOA->MODER |= GPIO_MODER_MODE4_1 | GPIO_MODER_MODE5_1 | GPIO_MODER_MODE7_1; GPIOA->MODER &= ~(GPIO_MODER_MODE4_0 | GPIO_MODER_MODE5_0 | GPIO_MODER_MODE7_0); GPIOA->AFR[0] |= (GPIO_AF5_SPI1 << GPIO_AFRL_AFSEL4_Pos); GPIOA->AFR[0] |= (GPIO_AF5_SPI1 << GPIO_AFRL_AFSEL5_Pos); GPIOA->AFR[0] |= (GPIO_AF5_SPI1 << GPIO_AFRL_AFSEL7_Pos);   RCC->APB2ENR |= RCC_APB2ENR_SPI1EN; // enable I2S Peripheral CLK SPI1->I2SPR |= SPI_I2SPR_I2SDIV & 47u; // set I2S Prescaler to 47 SPI1->I2SPR &= ~SPI_I2SPR_ODD; // set I2S ODD to 0 SPI1->I2SCFGR &= ~SPI_I2SCFGR_CKPOL;

Hi , Recently i buy STM32F103c8 Bluepill development board. I use STM32CUBEIDE create LED project and download using STM32utility tool. After programming done it will be automatically disconnect.Next, If need connect in STM32utility means need reset while connection making.otherwise it will not be working..By using coocox , i create sample Led Program and i download it through STM32Utility tool. Above problem is solved. always we connect and disconnect and program, program&verify . all is working fine..Why Bin or Hex created fron STM32cubeIDE is getting this problem. Any solution to solve this problem. I attach video. Check it

Hi,In the LPS33WTR pressure sensor,I want to program the LPS33WTR FIFO to a certain pressure and configure the interrupt as Threshold-based interrupt.No Where have I found the duration of the Interrupt logic change. I want to use it as a HW trigger once a threshold is crossed (pressure decreases).For how long will the Interrupt stay in 'high' state ( assuming it is configured as Active high AND Push - Pull).Thanks!

I need a position & speed controller for a brushless DC motor with hall sensor and quadrature encoder over Ethercat (slave).Any suggestions of Nucleo board/Controller/Ethercat adaptor for prototyping purposes please?

I have a straightforward question regarding the DWT counter. I am using the DWT->CYCCNT counter to count clock cycle differences in the STM32L431CC, and I noticed that CYCCNT is 32-bits wide. If I were to use HSI16 as my internal clock source, the CYCCNT would still go up to the maximum value of a uint32_t which is 4294967295, and not 16000000 based on my HSI16 clock source right?Thanks!timestamp_1 = DWT->CYCCNT; DoSomeTask(); timestamp_2 = DWT->CYCCNT;   if(timestamp_2 < timestamp_1) { /* I originally filled 16000000 instead of MAX_INT here */ timedifference = timestamp_2 + MAX_INT - timestamp_1; } else { timedifference = timestamp_2 - timestamp_1; }

hi, I'm developing software with IDE IAR for ARM using STM32H745XI.I would like to ask you, if possible, how to create a dual-core project without going through STM32CubeMX on IAR IDE by loading all drivers for both ARM (CMSIS) and ST HAL drivers with the correct project tree.Many thanks in advance!

It's been a which that I am using NXP FreeRTOS TAD and WHIS StateViewer until now that I've noticed about a new feature added to STM32CubeIDE 1.5.0 as Added FreeRTOS™ debug supportBut what is this exactly and what is included into it? Because I can't find any additional view related to FreeRTOS or any check boxes to enable Thread Awareness Debugging in debug configuration for STLink or openOCD (SEGGER JLink already had this feature) after updating to the latest version (1.5.0)

Hello,I have two X-Nucleo-BNRG2A1 demo board, with Nucleo Board, working fine with the SampleApplication of the X-CUBE-BLE2.The two module pair correctly, one being the Master, sending message to the slave.I would like now to use another device to connect to the X-Nucleo-BNRG2A1. I can see the bluetooth one the other device, but when trying to connect, it ask for a Key.What is the Key, or how to read it? Is there a way to enable Key free connection?Thank you

Using a Nucleo STM32F091RC board, I have configured the ADC to measure all channels in a sequence, i.e. all 10 ADC pins that particular chip has, and the 3 internal ones: temperature, vrefint, vbat.I calibrated the ADC, waited the time before enabling as said in the errata, measured Vrefint a bunch of times (with only that channel in the sequence at that time, just in case MUXing might create slight crosstalk), calculate VDDA from the reference and the stored values from system memory.When I meausre voltages on the 10 external pins, they seem all correct and reasonably accurate.Vbat also looks ok. Vrefint also looks like that is said in the datasheet.But the internal temperature is totally off.It measures around 95 °C, but the MCU clearly feels less than human body temperature.I have tried 3 things to calculate it:read the reference manual and implemented it myself. When that seemed wrong, as a sanity check, Ilooked whether the LL library had something, and indeed, it has the macro __L

I have a screen with some pictures, buttons and a custom keyboard widget. I want to show a modal window on this window. But when I do "view" on my modal window, it only covers the things defined in gfxdesigner not the custom keyboard widget. How can I include custom keyboard to so that it becomes part of the "main window" or is there perhaps an better / other way?

Hi.The datasheet of ST25R3911B shows recommended values of capacitors of 1uF (for AGD/VSS) and 2.2uF for others (VSPx-VSNx) plus a 10nF capacitor very close to the pins, according to the the picture:I just wanted to know if I should use these exact values, or if I can start my custom board project using 4.7uF/0402 for all these 1uF and 2.2uF capacitors. We already have the 4.7uF/0402 in stock. Just wanted to know if I can use them instead of 1uF/2.2uF values recommended on the datasheet. And also if I can use 4.7uF+10nF on VDD pin

Hi.We have a custom board which includes NFC and it is based on ST25R95 transceiver and it has a double layer (top and bottom layer) antenna/coil of 10.5mm x 26mm, 5 turns at each side and 0.3mm width for traces, 1/2oz copper thickness. The reading distance for NFC tags was not sufficient for our project so we decided to switch the transceiver to a ST25R3911B and keep using the same antenna. Use the same antenna because we don't have more space to increase its size, and now the objective is to reach a higher distance reading for NFC tags.We sent a bare board without components assembled to a university and they measured the antenna parameters of it with a ZNL 6 network analyzer, these parameters are required to calculate the matching componentes on "ST25R Antenna Matching Tool". v3.1.0.0 was used.**********************************************************NFC ANTENNA/COIL PARAMETER MEASUREMENTS FOR PCB-SL2-G-BLENETWORK ANALYZER: Rohde Schwarz ZNL 6****************************************

Hello,I am developing on STM32L4R9I-Disco, and I want to display ARGB8888 images on the round DSI display under the command of UART. For example, I send hex 'b2' to this board by uart, one image is displayed. I have succeeded some parts, but the image is not well displayed (the attached picture).Anyone knows what's the problem? Thank you.

Hi, i just started working/learning STM cards as an intern. I want to run C/C++ codes on STM32MP157A-DK1 ARM Cortex-A7.I did the getting started tutorials at wiki, and im using environmet version 2.1.0 release I followed these posts:https://community.st.com/s/question/0D53W00000M9GphSAF/using-stm32cubeide-for-developing-linux-user-space-applicationshttps://wiki.st.com/stm32mpu/wiki/How_to_manage_OpenSTLinux_project_in_STM32CubeIDEThen I wrote an the most basic hello world code. just want to get an build, deploy and see if its working properly then i will start working on the task that i given.#include <stdio.h> int main() { printf("hello world\n"); return 0; }The problem is when i press : Run as -> STM33 Cortex-A Linux deployment it gives an error and says : " Activation DeviceTree... failed"  I really dont know anything about this kind of work, i worked as a programmer but with visual studio, unity engine and unreal engine so this kind of environment is compl

I have found a problem when deriving a class from two base classes.class BaseA{public: BaseA() {} virtual int GetNumber() const {return 42;} };class BaseB{public: BaseB() {} virtual int32_t MathConfuscator(int32_t input) {return input * 97 % 5;}};class DerivedC : public BaseA, public BaseB{public: DerivedC() {} int GetNumber() const override {return 10;} int32_t MathConfuscator(int32_t input) override {return input * 10;}};Running these classes in a program e.g.:int main(){ DerivedC myDerive; int64_t myTick = 4078; int32_t tmp = ((BaseA*)&myDerive)->GetNumber(); if(myTick == ((BaseB*)&myDerive)->MathConfuscator(tmp)) return 1;}The first function call GetNumber() is executed correctly and jumps into the DerivedC function while the MathConfuscator function call crashes with a hard fault.I have tested this on an STM32G031 Nucleo-32 evaluation board using the STM32G031K8T6 procesor. The compiler chain is "9 2020-q2-update". To me it is unclear why I do get a hard fault when r

Hi, when I try to use pin #7 of STM32G031J6 as GPIO A14 configured as input with external interrupt, the debugger crashes and lose control of the application. This is not happening if I change pin, eg. use GPIO B0 on pin #5 the same way.Has anybody encountered a similar problem? Thanks, Elena

This is my code to generate the value of the lookup table?

I am playing with my STWIN evaluation kit and I am trying to understand the final step of configuration of the Machine Learning Core in the sensor. Are the configuration registers on the sensor flashed like that of an MCU when you load the ucf file? Is the sensor configured every time by the MCU upon reset?I ask because I am trying to use an MLC sensor in my design where it would be interfaced to am MCU where you program in Micropython. It would take some time to write equivalent drivers.

we have purchase this item LD1117S50CTR recently, Can i get the marking information, our QA department is asking us provide information to process production, thanks.

I will be using STM32F4 CPU in custom boards. The PCB will be space constrained and I plan on using STMX&IDE for development debug/programming devices. So is there a need for JTAG interface (10 pin) or can I get away with just having the SWD header?

I'm working on PCB with two MCUs, and I'm not sure how to connect power supply lines. Even after reading the datasheet and RM0433, I still find it confusing. Like, which one of the VDD33USB or VDD50USB should I connect and why? Do I connect both? Or do I need to connect VDDLDO? Or VBAT, if I don't plan to use battery and what to do with that pin in that case? Or do I need to connect any of USB VDDs if I'm not using USB or I can keep it floating? Or can I connect the same power supply on all 3.3V power lines? Or can I keep floating analog power input, and use on-chip one?Is there a nice document to explain it all in details? I was working with SILab MCUs before and the document simply had all scenarios, saving me the trouble of experimenting.

The problem that I am facing is that I implemented HAL_UART_Receive_IT function in a while(1) loop and then I check for the elements of buffer for \n or \r. After I type the first message it prints "String Received". But after that it continuously prints "Error". I read a few articles and i enabled the IRQ for the interrupt but i am confused about its implementation. I wish to know how exactly is it done.

I'm using FatFs without RTOS, and quite often the f_mount() call will fail. Right now it always fails, but in a previous version of my code it failed only 20%. My current mount code (using HAL) looks like if (f_mount(&fatfs, "", 1)) led_on_abort();and my initialization before in main.c looks like HAL_Init(); SystemClock_Config(); MX_GPIO_Init(); MX_DMA_Init(); MX_FMC_Init(); MX_SDMMC1_SD_Init(); MX_FATFS_Init(); MX_RTC_Init(); MX_NVIC_Init();I did enable interrupts and DMA for SDMMC1. That's why those init calls are before f_mount().Could there be a timing issue causing f_mount to fail? Note that changing the immediate parameter to 0 does not prevent the failure.When I'm debugging, everything works just fine. That's why I think there could be some timing issue -- not enough time between SDMMC/FatFs-Init and f_mount, or between f_mount and f_open (when not immediate).Any ideas?
