32kHz crystal for 32F411EDISCOVERY board

HelloI want to add a 32kHz crystal on a F411 discovery board for the LSE.On the schematics, X2 has the value XTAL_32K_20PPM but is not fitted.Does someone has some hints for choosing the right crystal ?Bests

Hello, I am new to STM32 and I am trying to generate PWM signal of 10 KHZ and 50% duty cycle and i am not able to achive it and I am using STM32L476VG DISCO board and for reference I have attached the code. Thank you

/*CODE to generate PWM signal of 50%*/#include "stm32l476xx.h"#include "pwm.h"void pwm_init(void){ /*RCC configuration*/ RCC->AHB2ENR|=RCC_AHB2ENR_GPIOEEN;//ENABLE GPIOE RCC->APB2ENR|=RCC_APB2ENR_TIM1EN;// ENABLE CLOCK ACCESS TO TIM1 //RCC->APB1ENR1|...

DMA stay in busy state when using HAL_I2C_Slave_Receive_DMA

Hello,I'm working on 2 NUCLEO-F767ZI Demo Board.I'm using STM32CubeMX with last firmware package to generate the code and STM32CubeIDE to modify it and debug it.One of the board is used as an I2C Master, the other as I2C Slave. Every thing work fine ...

Resolved! I need to use PG10-NRST as a GPIO. So I check the Reference manual to find out how to do it. I find that it can be done if I modify the field NRST_MODE to 2 and I really do this. But it doesn't work.The mcu still reset when PG10-NRST comes a low level.

Here is my code in main() to config field NRST_MODE: HAL_FLASH_Unlock(); HAL_FLASH_OB_Unlock(); gFlashOBST.OptionType = OPTIONBYTE_USER; gFlashOBST.USERType  = OB_USER_NRST_MODE; gFlashOBST.USERConfig = FLASH_OPTR_NRST_MODE_1; HAL_FLASHEx_OBProgram(&...

FDCAN2 4 times slower than FDCAN1 on STM32G491

I was finally able to find the correct settings to configure my CAN peripherals with correct bitrate after tweaking for a while in STM32CubeMX. The settings that work do not make sense. FDCAN2 is 4 times slower so I had to make clock divider for FDCA...

Resolved! PWM Output Not Generating Waveform for STM32F429ZI

Hi everyone, I'm just trying to test and verify some clock frequencies for a PWM waveform are correct. I used CubeMX to generate some code that has set the clock frequency of the MCU to 72 mHz and I am trying to achieve a 20 kHz PWM frequency. I enab...
