STM32 MCUs Products

I am using stm32h745 MCU for communication with external nVRAM using FMC example which is given in Repository. while writing to the memory chip select as well as OUTPUT Enable signals are coming as expected from MCU but i am not getting write Enable .

Hi, i am using stm32l4xx controller and facing the issue with flash. whenever the device is powered up the previous content (code) is not running could u please suggest what could be the problem.

NUCLEO H745ZI can't use DMA for DAC like shown in examples online with M7, only M4

SOLUTIONBuffer was being put into DTCM by cube. Ensure it doesn't do that, and you should be set.I want to start by saying that it works on the M4, but not on the M7 and I don't know why. The M7 on pretty much all the peripheral configurations I've s...

STMStudio GDB source code

Hello all from ST!The STMStudio ships a modified version of an open source software called GDB:As you see from the output above the GDB is licensed under the terms of GPLv3+.The GPLv3+ license require the modified sources to be shared.Could someone p...

"STM32" vs "STM32 Arduino" - I2C difference

Hi, I am trying to debug my code with logic analyzer and see why my code works on "STM32 Arduino", but does not work on "STM32". Viewing at logic analyzer I see that "STM32 Arduino" much more consistent.Why could the message be different "0xD1 0x00" ...

RTC running fast on STM32L433

Hi I have setup the RTC on the STM32L433 and the clock is running about 5 second fast in 24 hours. I am using a 32.768KHz crystal, which is directly next to the processor . I have set the RTC->PREDIV_A to 0x 7f, and RTC->PREDIV_A to 0x ff, and selec...

M41T65 to power cycle MCU

Hi - I am fairly new to RTC and Watchdog Timers, so my apologies in advance if the questions seems trivial =) There seems to be some concerns that when used in conjunction with Particle Boron MCU's, simply resetting the MCU will not suffice but Power...

Selective Breakpoints and Interrupts?

Running STM32CubeIDE 1.5.1 with Nucleo-stm32L433RC trying to get LPTIM1 to work consistently. In Selective03.png I show the initialization of the LPTIM1 (LPTIM_PERIOD is 32767 and LPTIM_PULSE is 16383). So I expect CompareMatchCallback() to happen...
