Hi, I made a minimum CubeIDE project for a Nucleo-L4R5ZI. It clocks the RTC from LSE using the X2 quartz (NX3215SA-32.768kHz-EXS00A-MU00525) and outputs a 512Hz calibration signal on PC13. The output frequency is only ~492Hz which is a deviation of ~5%. I couldn't find any reasonable explanation. Any ideas?

Hello,I am trying to develop a FreeRTOS application which need to detect/read/write an NFC tag.I managed to make the NFC part work (based on ST's example code), but after changing my task stack size, a usage fault occurs (FORCED, INVSTATE).After a few attempt to reproduce and solve this, I noticed the following :Task size of 1024 words : work as expectedTask size of 768 : hard fault / INVSTATE in NFC library (see below)Task size of 2048 : hard fault / INVSTATE with PC out of any source file (0x20001fe8)ReturnCode ndefT4TPollerSelectFile(ndefContext *ctx, const uint8_t *fileId) { ReturnCode ret; rfalIsoDepApduTxRxParam isoDepAPDU;   if( (ctx == NULL) || !ndefT4TisT4TDevice(&ctx->device) ) // HARD FAULT on this line { return ERR_PARAM; }   ndefT4TInitializeIsoDepTxRxParam(ctx, &isoDepAPDU);   if (ctx->subCtx.t4t.mv1Flag) { (void)rfalT4TPollerComposeSelectFileV1Mapping(isoDepAPDU.txBuf, fileId, (uint8_t)sizeof(fileId), &isoDepAPDU.txBufLen); }

This is not made by default when we use STM32CubeMx to set SPI and DMA together. Hello, I am working on a full duplex SPI communication through DMA using STM32H7. So, I have bought 2 NUCLEO-H743ZI, one to be the master, the other to be the slave. I have downloaded, built and flashed SPI_FullDuplex_ComDMA example via TrueStudio. As there is no ''TrueStudio format'' example, I have generated the project with STM32CubeMx and replace Inc and Src generated files with SPI_FullDuplex_ComDMAfiles. And tadada! ... It is not working correctly....... Only a few bytes are sent and Rxbuffer is never filled. I have made connexion wires as short as possible and I have increased spi clock prescaler to get ''slow, nice and smooth'' signals. Electronic not seems to be the problem. I have modified the exampl

Help! I'm new to ST development tools. All I'm trying to do right now is generate an MC Workbench example project. Any example project.MC Workbench GENERATION always reports the following error:"The ST intranet updater server is unknown: mcucrossselector.codex.cro.st.com"Any suggestions greatly appreciated.-----Details:MotorControl Workbench 5.Y.4 (en.X-CUBE-MCSDK_5.Y.4_v5.5.4.zip)STM32CubeMX 6.4.0 (en.stm32cubemx-win_v6.4.0.zip)STM32CubeIDE 1.7.0 (st-stm32cubeide_1.7.0_10852_20210715_0634_x86_64.exe)(All downloaded and installed yesterday.)It does generate a CubeMX project, which generates a CubeIDE project, but that source code is has a massive number of undefined symbols. I have not changed any config or preferences settings. It's all "fresh out of the box", and I'm just following the provided instructions.((Context: I have 2 new B-G431B-ESC1 boards, and started out trying to build the example projects for that board. When that failed, I started trying other examples, and it looks l

After install node-red-contrib-line-messaging-api.I closed STM32CubeMonitor and open it again.It appears an error dialog box as attached picture.I tried to uninstall it and then install it again.It still fails.

Hi I am currently working on a project where I have to implement TCP/IP stack on STM32F429ZI 144 pin nucleo board. Board has PHY chip.My question is how does the MAC controller knows when a jabber or collision event occurs since these events are handled by PHY chip. PHY chip shown in schematic for nucleo board, has no connections other than RMII (like error interrupt?) to STM32 MCU.

I'm trying to get square pulses on PB8 with TIM16.1 output compare, but no pulses on pin (timer seems working: CNT counting, SR flags changing).Setup code:gpio_mode(GPIOB,8, GPIO_MO_AF); gpio_af(GPIOB,8, 2); // PB8 as AF2 rcc_apb2_on(RCC_APB2_TIM16); TIM16->CCMR1 = TIM_CCMR1_OC1M_0 | TIM_CCMR1_OC1M_1; // toggle on match TIM16->CCER = TIM_CCER_CC1E; TIM16->ARR = TIM16->CCR1 = F_CPU / EADC_MCLK / 2 - 1; TIM16->CR1 = TIM_CR1_CEN;Similar code for PA4 and TIM14.1 works as expected:gpio_mode(GPIOA,4, GPIO_MO_AF); gpio_af(GPIOA,4, 4); // PA4 as AF4 rcc_apb1_on(RCC_APB1_TIM14); TIM14->CCMR1 = TIM_CCMR1_OC1M_0 | TIM_CCMR1_OC1M_1; // toggle on match TIM14->CCER = TIM_CCER_CC1E; TIM14->ARR = TIM14->CCR1 = F_CPU / EADC_MCLK / 2 - 1; TIM14->CR1 = TIM_CR1_CEN;

Hi, I am trying to write an interrupt code to trigger LED(PB14) using user button on my NUCLEO board(PC13). however, as I observed from the debugger, pending bit for line 13 constantly at 1 without pushing the button at all.The EXTI->PR1 = 1<<13 still executed but it can't clear the pending bit.Could someone point out my problem? here is my code.Thank you./*--Header--------------------------------------------------------------------------------*/ #include <stdio.h> #include <stdint.h> #include "stm32l4r5xx.h" /*--Define--------------------------------------------------------------------------------*/ /*--Global-Variable---------------------------------------------------------------------- */ /*--Function Prototypes-------------------------------------------------------------------*/ void initPort (void); void Blink(void); /*--Main----------------------------------------------------------------------------------*/ int main() { initPort(); while(1) {   } } /

Hi. I am currently trying to implement USB headset on my old STM32F407 Discovery board.In USB descriptor I have simple topology with two input terminals, 2 out terminals and feature unit. Also I describe two streaming interfaces (IN and OUT) and one control interface.When I am connecting this device to my laptop, host correctly recognize both interfaces. I can play music from host via discovery board and I can record sound from mic, connected to my discovery board.The problem begin, when I am trying to do that simultaneously - try to record sound from mic, during host`s music is playing. When I am start recording, host`s music suddenly stops, but recording is continuing. When I stop recording, host`s music is still not playing. It seems that my device completely lost ability to play music from hots but preserves ability to record sound from discovery mic.After debugging I find out, that after that unsuccessful try of simultaneous work of both interfaces, the OUT EP interrupt is stops.

Good morning, I have developed one board with CC2640 running to 1.8V (External Regulator Mode), this board has one LIS2DH12TR with VDD & VDD_IO to 1.8V, the communication is SPI, when I read register "WHO_AM_I" (0x0F) I get 255, not matter what register, clock or pol & pha I set... I always get 255, if CS=0 then this chip works as SPI and the interface 4-wire is default, what am I making bad?I hope somebody can to help meRegards

Hello,I am looking at the LSM6DSM datasheet for power draws. Here is an exampleAccelerometer Current Consumption @ ODR=52HzVDD = 1.8 VCurrent = 25 uAPower = VDD*Current = 45 uWDoes the current required by the LSM6DSM accelerometer change if VDD is toward the upper end, say, 3.3 V? Should I expect lower, or higher, power draws? Basically fill out the following:Accelerometer Current Consumption @ ODR=52HzVDD = 3.3 VCurrent = TBD uAPower = VDD*Current = TBD uWThanks in advance!

Dear CommunityI am working on a project right now, using a STM32H725 with an external PHY (USB3300-EZK).The board is working and using FreeRTOS with CMSIS I have USB HS working.But trying to build my project on Azure with USBX, I can't get USB HS to work.Diving into the USBX libraries I noticed that:The function 'ux_device_stack_initialize' in 'ux_device_stack_initialize.c' is not using its 'device_framework_high_speed' pointer to high speed FW.Am I missing something? Or is the USBX HS implementation with EXT PHY not functional?Does anybody have a working Azure/USBX EXT PHY project with HS USB?

Hello, The physical infrared filter give some faulty measurements and wont stick perfektly on the VL53L5CX.kind regards Maik H.
