STM32 MCUs Products

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...

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 ...

Boot configuration for STM32G071

For STM32G071 controller, I see difference in information provided in Ref manual (RM0444 Rev4) and STM32 microcontroller system memory boot mode applicate note(AN2606 Rev44).In Ref manual on Pg 60 section 2.5 it is mentioned that for selecting boot f...

How to debug without using a microcontroller ?

Hello, I would like to be able to run a program without using a board. I would like to be able to do continuous integration with Jenkins but I haven't found any solutions to emulate my STM32L072. Someone would have any idea ?
