Resolved! Problem with first project Nucleo-144 STM32H745
I'm sttarting with STM32. I've bought Nucleo STM32H745ZI-Q and I'm trying to bling a LED (or any other GPIO). I've downloaded CubeIDE, CubeMX is included in it. I'm tring to Toggle GPIO pin, i've tried few tutorials on yt with no luck. ST-Link is up ...
I have a question about a signal (Interrupt signal) in the STM reference manual RM0433. On Page 697 , table 125 the Trigger input 14 is named "Lptim5_ait". I cant find any reference for this signal.
I'm trying to set up a BDMA Stream with Lptim5 as trigger source. Which interrupt on the Lptim5 can i use? "Lptim5_ait" is not listed as an interrupt in the Lptim section of the manual ( page 1881, table 350).Happy new year and thanks in advance!

Recentrly I've heard about a letter sent to some customers which informs about increasing prices across all product lines effective from 1st of Jan 2021.It describes that current pandemic has created challenges in semiconductor industry which has lea...
Resolved! Is STM32F412VET6 on-the fly firmware update possible?
Hello,I'm working with a STM32F412. In my process, the STM32 will receive a firmware. The idea is to flash this firmware (that is in RAM) to the STM32 for it to execute after a reset. I don't know if it is possible.If it is not, what are the properti...
Uart receive not working after a period time.
Hello,My project uses 4 uart interrupts on stm32f476 with freertos.I have a problem with one of 4 uart interrupts. (uart7)It works normally for a period of time, after that it doesn't work anymore.I tried changing the interrupt priority but the resul...
STM32G070RBT6 port configuration possibility query
Hi we are considering the STM32G070RBT6 64pin for its wide support for multiple PWM,ADC and USART ports, and would like to confirm that this part can simultaneously support 12 PWMs, 15 ADCs , 3 USARTs and 1 I2C . We are planning to use 2 of these as ...
Set RTC Alarm Interrupt using HAL Drivers STM32F4
Hi,I want to trigger the RTC alarm interrupt 10 seconds after the currently read time.The interrupt also triggers sometimes, but not every time the function "SetAlarmAInterrupt" is called.What could be the reason that the interrupt only trigger from ...
Hi. I have a query, related to the global interrupt of the Uhart. Is there any way we can enable more than one interrupts for a singal uhart.
Actually I am using a single interrupt to receive, data from another processor in two different arrays. Due to this scenario and interrupt being called at two times in different arrays, only the first array receive interrupt accurately.
How to bypass or reset the Hard fault error?
Hello, I'm working on a project based on STM32F446 controller. In my project, I'm reading and writing some data on the external flash. Its interface to one of the SPI port of the controller. The frequency of data accessing (reading and writing) is a ...
