STM32 MCUs Products

My virtual comport is not recognized by Device Manager.

I need some help. I have a design that uses the STM32F407zgt. Up to now every thing has been going prefectly.  I started my design using the STM32F407VGT or the Discovery board as my breadboard / proof of concept. With the 407VGT, I was able to crea...

How to add a 3.5 character (MODBUS-RTU) delay after the stop bits. Is that a guard time?

I'm using an STM32L486 as my master and as the slave. My issue is the slave transceiver I want to use pulls the RO (RX on the STM32) pin down after receipt of a message. The RTOI doesn't fire until the RX pin goes high from the next message.

I would like to activate the RISING FALLING function also on PIn 13 and 15 but I can't do it.I'm probably not able to edit several files that I list

I am Going To Generate 10us delay for ultrasonic sensor in STM32L152RET ,HAL_Delay() is Create Delay Upto ms,How It Can Generate?

Integration of real time data.

Hello,I am trying to estimate soc by coulomb counting method.In coulomb counting we required integration of discharge current.I am getting accurate discharge current but unable to add them by using array. I tried using array :float buffer[50]; float ...

sprintf causes hard fault.

I use "sprintf (string,"comment"); everywhere now for some reason, I am getting a hardfault. in an innocuous print.length += sprintf(String + length, "Received Packet from ");length is only 15.String is declared as char String[256];I guess it is us...

What is the maximum baudrate of the USARTs on the STM32G441 series?

hi, when playing wav files from sd card through spi interface via the i2s (audio codec pcm1770) interface( dma enabled) my audio is little bit slow ..do spi have the enough speed to do it or should i choose sdio for sd card interface ?

hi all i want to know whether stm32 f107/105 can use sdio interface for sd card ?

Where does my const array go? (memory type?)

So, if we have a large amount of hard coded data we want to incorporate into my program, my presumption was that a const array would allow the compiler to treat the data more like code, than data, in terms of cost against your CPU limits.This was alm...
