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...
I have an STM32H745 Discovery board. The first problem I encountered was when I was creating interfaces using TouchGFX. I could upload them to the microcontroller via the application without any issues, but when I uploaded the code file through C...
I'm new to microcontrollers. I bought a Nucleo-H755ZI-Q, I connect it to my PC, I make a simple program like turning on and off a LED but the card doesn't do it. I don't know if I have to make any adjustments because it's new.
Hi, I am integrating the STM32H7S7L8H6H in a custom board. In the reference manual I found two settings which I am looking for clarification for: 1) SBS_PMCR has a AXISRAM_WS bit to enable a single wait state for the AXISRAM. I do not have ECC enab...
I redid FatFS to work async or in polling mode. Works well on my STM32H755zi, on CM4. Most functions are enabled, though I didnt do all of them. Maybe plan on adding them later if there is any interest.Figured I'd share since not having an async FatF...
Hallo,I'm compiling with this option <-fpack-struct=1>Why, with this option, the instruction<WRITE_REG(hdma->Instance->CBR1, 0U);>generates hard fault? I don't understand, without changing nothing.thank you.
I want to use the on-board RTC while all power (except VBAT which will be connected to a battery) is turned off to retain the clock.Is it possible to power the on-board RTC from VBAT and turn off ALL other supplies?What will happen after the other su...
Hi could somebody please help me with this: i am a beginner ,i have set the Timer_init and Gpio_init with bare Metal i'm working in STM32F429ZIT and i'm aiming to control GPIO pins PG13 and PG14 using the PWM channels with two channel each for every ...
Hello, I'm studying the STM32F767 MCU, and I noticed that in STMCubeIDE is possible to configure if the speculation is permitted, but I didn't find an explanation of this feature. If I set Speculation disabled, do I set the flash strongly-ordered? Do...
Dear STM32 Community, I am currently working on a project using the STM32F072RBT6 microcontroller, where I have implemented a custom bootloader to load an application program into flash memory. However, after the bootloader successfully writes the ap...
Hello,i use at a STM32F429 the PD5 pin to drive a PNP BJT transistor to switch a sensor supply:PD5 is configured as open drain, and when the stm32 is pulling PD5 low, the transistor supplies the sensor with 5V power. This works so far.But when PD5 is...
