STM32 MCUs Products

I am using stm32f303rbt6 MCU, And I am using UART &USART, while working with this i found that some UART & USART are 5 volt tollernt, But Tx pin of these UARTs are not providing 5volt, they only provide 3.3 volt, Then how can it become 5 volt tollrent,

Can anyone explain it to me?

I want to use 6M GPS with STM32H750 but don't have any examples, only STM32F103, can you modify it to work with H750 please?

Nanosecond delay

I want to generate a nanosecond delay on the STM32F407 µC, the closest delay I can have is 6ns using either TIM 9/10 or 11, because they work on a 168 MHz clock. But when I use an oscilloscope to visualize whether I successfully generated a 6ns delay...

STM32F4 - Watchdog in STANDBY mode

Hello, After reading some applications note I did't find the way to implement a watchdog for my case.My case:the MCU shall sleep during 12hone function on Bluetooth stack in a .a (provided by TI) takes 1024msMCU is running at 48MHzWWDG can't be used ...

Can someone help me how can I communicate between a PLC and a STM32? Like how to use convert seial to a profinet?

Hi all;There is board that have to design which needs to get data from a PLC.The PLC protocol probably would be PorfiNet and I want to use the data from PLC in MCU.I am kind of new to PLC and I don't know how the PLC protocol work and how they conne...

Im trying to control the Arduino Multifunction Shield by using stm32l053r8t6. What is the coding for the 4-digits 7segment on the multi function shield?

Im only can display the 7segment by using "sortSegment (numbers);" and it only display at 4th 7segment. How can i select which 7segment i want to display, and how can i display Characters?

PA2 & PA3 are connected to the internal ST-Link controller, therefore not usable for TIM9 pwm output if any one konown how to configure ?

Can I use the STM32F4 BSRR with a 32 bit write to set/reset GPIO bits simultaneously?

I've defined the lower 8 bits of a STM32F4 GPIO port as a negative-true open-drain output. My current code uses two 16-bit writes, first to set all 8 bits, then another to selectively clear them. It would seem that I could do this with a single 32 b...
