I am using inbuilt RTC of STM32G941re , I am facing problem in interupt,when I set one min the alarm interupt comes after 30sec only not 1 minutes
The alarm time set properly but interupt in half time &sometimes I not came,please share if any one have idea
STM32F0 ADC externally triggered and software triggered simultaneously?
Hi,I need to measure 5 signals using the ADC. Out of the 5 signals, one is current (voltage across series shunt) which needs to be measured ONLY during transistor ON time, hence the ADC needs to be externally triggered by the PWM (OCREF). Other chann...
High sampling rate with ADC and no DMA
Hello All,I have some questions regarding the ADC of the STM32G071RBT6. Technically we can reach a conversion time of 400 ns if we use the internal ADC clock (35 MHz) and a sampling time of 1.5 cyc. OK, that's pretty good idealy.I am running my micro...

Resolved! Data coherency with DMA and I2S audio on STM32H7
Moving from a audio effect prototype based on the STM32F407 to the STM32H757. Did a lot of stuff on the F4 with audio but on the H7 I'm getting stuck and can't get a simple audio loopback with DMA. I'm using Cirrus Logic's CS5343 and CS4344 as extern...
Resolved! Spurious RDPERR and RDSERR when all protection and security settings are off
I have a project running on an STM32H743IIK6. The program periodically tries to write to the last page of FLASH and the HAL fails fairly often. The failure is in the start of HAL_FLASHEx_Erase where it calls FLASH_WaitForLastOperation before beginnin...
How to use LPTIM_TimeOut for a simple one-shot delay ?
I'm trying to realize some simple timings/delays in my application using the LPTIM, and although most of it is working, I don't understand it 100%.So the LPTIM is set up to run on the LSE clock (32768 Hz) (with a prescaler of 16, so the LPTIM is runn...
What MCUs have backup SRAM maintained by VBAT?
STM32F407VG has 4kB of backup SRAM that's preserved when VDD is removed if VBAT is present. A few other MCUs in the STM32F40x line have that feature too.Do any MCUs outside of the STM32F40x line have SRAM that's preserved with VBAT? Is there a way ...
