STM32 MCUs Products

I want to program an STM32F103C8T6 in-circuit using the SWD interface and an ST-Link. If I don't have a reset button, do I still need to connect a capacitor and pullup resistor to the NRST pin?

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...

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 ...

[BUG] SD_read in sd_diskio.c fails with DMA in cached memory areas

Hello,there seems to be a problem in function SD_read with reading data in DMA transfer mode to cached buffers.I've enabled cache handling with#define ENABLE_SD_DMA_CACHE_MAINTENANCE 1but there is a serious problem with calling SCB_InvalidateDCache_b...

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
