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...
On STM32L476 Discovery and TrueSTUDIO 9.0.1, USB CDC fails on Windows 10, if code is generated by STM32Cube MCU package of STM32L4 version 1.12.0. Back to version 1.11.0, it works fine. Furthermore, at 48 MHz USB clock, if SYSCLK = 48 MHz, the USB c...
Hi,I have asked this question before, but this time with a different aspect.Board support for STM3240G-EVAL board was available in Keil V4. In Keil V5, it's not available. Is there any way that I can copy some files from V4 installation to V5 install...
I am working on a very power sensitive application involving a STML431 processor running only off a battery. I plan on using Shutdown mode most of the time with an hourly wake up. I am looking for 1 measurement (maybe averaging a few actual samples)...
Hello,I'm having some trouble using the timer based interrupts.I have some very basic experience in mcu programing but I'm new to the STM32 platform and I had to adapt to it rather quickly. Therefore I lack some of the basic knowledge.My first questi...
I have been trying to perform SPI communication and observe outgoing and incoming data through MOSI & MISO. There is a weird problem in SCK weveform There are the codes I wrote :#include "stm32f10x.h" #include "stm32f10x_rcc.h" #include "stm32f10x_gp...
Hello, I'm designing a PCB with an interface to an existing STM32769 board. I would like to use one of the STM32 timer inputs to trigger a timer. When the timer reaches its "compare" value it should trigger a DMA request for an SPI transaction. Accor...
Hi,I am starting to program STM32 devices and I have an STM32F745 chip. Since I want to learn all the details I'm programming it from scratch, using only the definitions from CMSIS.I have a very simple program where I have 2 LEDs on PB6 and PB7 respe...
i made this code to blink an led with systick time but it does not work can you please correct this. i am using stm32l152rc discovery board. #include "stm32l1xx.h"while { if (SysTick->CTRL |= SysTick_CTRL_COUNTFLAG == 0) { GPIOB->BSRRH |= GPIO_...
Posted on May 01, 2018 at 16:12 I am trying to use CFFT function for my STM32 microcontroller in Atollic TrueStudio. But I am unable to use any of the DSP functions. I get the error - undefined reference to `arm_cfft_f32' and undefined refe...
Hi all,I am unable to wake up my mcu from standby mode using any of the wake up pins. Below is my code. Any help is appreciated.Thanks. /* Private function prototypes -----------------------------------------------*/ void MX_GPIO_DeInit(void) { ...
