STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Hey guys!I am trying to implement a difference equation into the STM32 MCU, however Iam getting this from the output of my DAC and I have no idea why this is happening?#include "main.h" #include <stdint.h> #include "arm_math.h" ...
I created my application using the CubeMX. Here are my read and write routines, my QSPI initialization routine, and while loop. I am using the USB to display what is read from the QSPI flash memory. I am writing a string to the memory, but when I rea...
Hi, I'm using adc single channel with interrupt. the sample time is set as 56 cycles, and the adc clock is (108MHz/4=27MHz). So the sample rate is 27MHz/(56+12)=397KHz. I also using DAC to generate a sinewave with the frequency of 1KHz. If what I cal...
Dear All,Board: Nucleo - H745ZI-QWhat am I trying to do ?I am trying to measure pulse width of an signal using input capture mode of timer 2 channel 1. Then multiply that width by two and wait for that much time and generate an output pulse using out...
I configured timer1 for pwm generation center aligned like below in cube ide.I update duty cycle writing directly CCRx register asyncronously in the code.Most of the time pulses are effectively center aligned but sometimes not (nor left or right ali...
Dear All,Board: Nucleo - H745ZI-QWhat am I trying to do ?I want to measure pulse width of an input signal using a busy loop and a timer. I keep monitoring a pin configured as input , when a zero is detected (by default input is around 3 volts), a fun...
Documentation say ADC have max 4Msps, but it refer olways to 60MHz to adc (60MHz * 15 cycle = 4Msps) but manual say ADC max frequency is 170MHz, then 170MHz * 15cycle = 11Msps.This clock is different from Fadc (aka adc kernel clock)?https://www.st.co...
Hi,i'm working on a STM32H755II MCU, I followed this guide and setup two debug configurations one for CM7 (that downloads both codes) and one for CM4. I added on the CM7 project the common implementation for printf:int printf_swo(char *ptr) { uint32...
I ran timer OC mode on PA8 (TIM1_CH1) on STM32f407VGT6 using HAL and it works fine. Then I decided to set up it by means of LL and there is not any output on PA8. I checked my code with Example_LL projects of STM32F411RE-Nucleo in ST F4 repository. I...
There are several FDCAN peripheral registers on the STM32H743 that hold the starting address of various elements used for FIFOs and filters. Are these addresses relative to 0 or to the physical address of the FDCAN message RAM (0x4000AC00)? The Refer...
