I am prototyping an application on a Nucleo H7 board and I would like to use 50 MHz SPI master for performance reasons.At lower speeds (25 MHz, for example) I am able to generate a fairly clean SPI Mclk that passes requirements, however at 50 MHz I e...
Hello, i'm using an STM32H7 but unfortunately for a known bug of the firmware package i'm not able to select the ADC prescaler. Uprading to a newer firmware package is not considered.At the moment i resolved applying a prescaler with the linehadc1.In...
My main purpose here is to write sensor data into the text file. Planning to send the data through COM port and read and write the data into the text file using MATLAB. This is the only way to write the data into text file that I am thinking about wi...
Hello all, I am currently working on a project with the STM32H743VIHX and I have been having some issues getting SPI communication with an external DAC working. The test I have built is supposed to transmit 24bits of data to the external DAC and reco...
Hello,I'm counting a 10MHz oscillator(with external clock mode 1) for 1 second using the stm32f0 processor's TIM1. I get about 10 000 000 pulses.Then the system has a starting point and I start the 1s counting process here. The timer counts a maximum...

Hello guys,I have adapted this example from repository to work with a STM32L071CB:STM32Cube\Repository\STM32Cube_FW_L0_V1.12.2\Projects\NUCLEO-L073RZ\Examples_LL\ADC\ADC_SingleConversion_TriggerSW_DMAIt works fine until I want to add RTC and select L...
Hi,So I want to have a timer interrupt of 15 seconds. So I calculated the values of pre scalar and counter accordingly:Prescalar - 18356Counter - 65347I just wanted to ask if I set such values. Will it work? Cause I tried the same using an LED Toggle...
I want to be able to implement different projects same way as implemented from Atmega328 of Arduino. So i want to move from Arduino to STM32 for better performance and technology.
Hiiii,I'm trying to create multicore communication in Nucleo-H745zi. I want to call interrupt in the second core. I just want toggle LED in second core after interrupt came from first core. I checked the articles and other stuffs on internet but i ca...
