STM32F407 Sector Flash Erase forces WWDG reset

Hello all,I am facing following problem:Trying to perform an erase operation of a flash sector forces a WWDG reset. The WWDG is initialized with following settings: hwwdg.Instance = WWDG; hwwdg.Init.Prescaler = WWDG_PRESCALER_8; hwwdg.Init.Wind...

Footprint of a Microcontroller

HelloI found this article of ST about an LCA of a microcontroller: https://www.st.com/content/st_com/en/about/st_approach_to_sustainability/sustainability-priorities/sustainable-technology/eco-design/footprint-of-a-microcontroller.htmlIs it possible ...

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

Looking for an I2S with DMA example for reading from a MEMS microphone.

I'm building a micropython firmware for running tensorflow lite for microcontroller examples. One of the main reference examples is called micro_speech and involves reading audio from a MEMS microphone at 16Khz using DMA and I2S and then feeding it ...

Is there a way to get the F4 I2C peripheral to toggle the SCL line while it is in the busy state i.e SDA is externally held low by a slave device.

STM32F401CCU6 Blackpill failed connection. I am currently programming blackpill via STM32F7 Nucleo board in STM32Cube, it worked for a while on two Blackpill boards, but now it is not allowing to Erase flash memory, tried almost everything

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

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 ...
