STM32 MCUs Products

Hello, i have to solve the task: Configure the MCU to operate with a system clock frequency of 72MHz. Make sure that the clock signal is derived from the external oscillator (HSE). Find a way to show the system clock frequency (SYSCLK) at an output pin.

This is my code so far.I solved the clock frequency of 72MHz with an excel sheet and imported the file which got created, so that is working. My HSE Speed is 8 Mhz.Now i dont get how to mirror the System Clock onto the MCO output pin.This is what i t...

How to write code that is port flexible? I have a project I want to do that the UARTs used may change by end-user config setting. So it may have communication on one or many UARTs (almost like a matrix scheme). How do I abstract the UART(s)?

STM32F4 I2C SDA & SCL rise time

Hi, I working with STM32F401RET6 64 pins Nucleo board with IAR.According to the datasheet DM00086815 Section 6.3.19 SDA and SCL rise time = 300ns.I open the project from “STM32Cube_FW_F4_V1.25.0�? STM32F410xx-Nucleo\Examples\I2C\I2C_TwoBoards_ComPoll...

Hi everyone, I'm currently working on stm32f4 nucleo board. I have a analog device based HMC767 PLL (datasheet and user manual link below) eval kit. i want to sweep a bandwidth of 150Mhz( strt freq= 8.0ghz stp freq= 8.15ghz).

I'm using SPI communication for generating the sweep.But Unfortunately Im not able generate the sweep as desired and the PLL remains in the default state giving 9 gHz single tone frequency.please help me if any one has implemented the HMC based PLL ...

Change peripheral on running

HI,I am looking for an easy way to be able to change the pin use destination of the micro while running. I give an example for a project that I have to do. On some pins of the micro brought to a connector I have an SPI peripheral, on this connector I...

How do you like this record?Here, a set of structure elements is used as a parameter. Yes, this is one giant structure for all MK legs, with all options for filling, including alternative functions. For each mk, you need to build your own unique stru...

Error in STM32G4xxx Reference Manual, RM0440 Rev 5, Page 723, Table 177:Table 177 incorrectly says ADC_CFGR2 is located at offset 0x0C. The correct offset is 0x10.

Timer implementation

I am using STM32F072RB.On my system there is 5 buttons(which is connected to GPIO).I am reading that GPIO continuously to detect the button press.If there is no any button press detect for 10 min, I want to generate a alarm. And if any of the button ...
