The STM32L431 RTC clock is slowing down
We tested the RTC clock and found a phenomenon that the system kept VDD3.3V in standby state and then disconnected VDD3.3V in standby state, but the RTC clock did not run slowly. If the system controlled automatically and disconnected VDD3.3V in slee...
How to interface an external ADC for highest speed?
Hello, I am planning to use the STM32H7A3ZI for a personal project and want to achieve the highest speed possible with an external ADC while storing at least 16 million samples in an external memory. In the tenths or hundreds of MSPS range, ADCs tend...
Resolved! Why doesn't it enter when I press the button to enter standby mode?
I sleep at the time I set with rtc on the stm32f103c8t6 microcontroller. I wake up with the alarm I set. No problems so far. I want to sleep when I press a button. But when I press the button, it sleeps, then wakes up immediately and sets the alarm t...
Clock precision on a STM32L476
Hi all, I need to drive the ADC with TIM1 at 4MHz, drive by an external event.I want to know the clock precision on this timer. For the moment I use HSI16 and the PLL to have 80MHz on APB.I also have a LSE for the RTC.but what is the precision. I nee...
LPTIM match interrupt discrepancy on STM32U5
Hi,We are working with STM32U585AI processor. Our software is based on an RTOS and we are using LPTIM to generate OS ticks.Our system runs from either PLL@160MHz or HSI@16MHz depending upon system load. LPTIM is fed directly from LSE@32768Hz.We are f...
Flashing Issues
A strange issue is observed, i am able to flash using STM32 CubeIde and shows flashing successful, but when run command using debugger the code does not execute, it stays at while (1). Any possible reasons why such behavior happens? Please advise.
