STM32 MCUs Products

STM32F407VGT on Discovery Board. Timer2 input channel 2 PA1 is not triggering Input Capture interrupt. Timer2 Clock 84Mhz.(HSE with PLL for clock) void HAL_TIM_IC_CaptureCallback() is not invoking even after applying proper signal to Timer2 IC pin.

I have tried to create a PWM signal using Timer1 and then feed that to Timer2 running in Input Capture mode. The Timer1 PWM output is working fine and verified using DSO. But in case of Timer2 the Input Capture interrupt call back void HAL_TIM_IC_Cap...

Can't change SYSCLK in UART HyperTerminal example

When I create the UART_HyperTerminal_IT project in STM32Cube, SYSCLK's source is assigned to PLLCLK:  RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI;  RCC_OscInitStruct.HSIState = RCC_HSI_ON;  RCC_OscInitStruct.HSICalibrationValue = RCC_HS...

Any new CPUs?

When distributors have zero stock, it is hard to know about new CPUs. Are there any? Fast do it all CPUs are interesting and so are Linux CPUs.PS I am 110% happy that I didn't use any of those in my paid designs.

i want generate 3 phase pwm AC signal. i'm using STM32F730. AS per its datasheet its Timer 1 has three channels that can be used to generate 3 phase. But i'm unable to understand how give phase difference {120 deg) between three phases.

STM32 DFSDM simultaneous sampling of 8 MEMS microphones

I am working on a project where I would like to gather PCM data from 8 MEMS microphones, and naturally I found the DFSDM peripheral interesting. The PCM data will be sent over lightpipe ADAT using a SAI but this is out of scope of this post.This is b...

STM32H7 UART BAUD RATE ISSUE

Hello! I'm developing application using STM32H745 with uart interface. The problem is the behaviour of uart baudrate. I configure with hal driver uart on baudrate 115200 and try echo with terminal. The problem is that sometimes i recieve wrong data ...

Import grbl-advanced with makefile and code

Newbie here! I am trying to import grbl-advanced into STM32CubeIDE. My board is Nucleo-F446RE. Is there anyone who can tell me how to do it?Thanks in advance!Judy

problem with the SPI Receive DMA1 in the STM32H723ZG?

I am using the STM32H723ZG as my development board. Here I am trying to do the SPI communication. I have an example program of the same board I had tested and it is working fine but in that they have used the BDMA for the receiving side. but I need t...
