rtc time

Hello, I am using NUCLEO-F429ZI. I add one battery on my board and work on RTC. RTC is working, however, all time(null), clock() and so on don't work properly as soon as I remove semi hosting. After I dig the information, I know time(NULL), clock()...

I need to know the register name is changes every datasheet.

Hi, This is sureshkumar, I bought one STM32 popular udemy course, on that course have one video that trainer shows some registers to set the pin directions. but my data sheet is showing different name of the register. on that video showing MODE regis...

A workaround for the fact that LPTIMx CNT register is read-only and typically do not have a reset

In many of the STM32 processors having LPTIMx timers the CNT register is read only and there is no explicit reset which will clear the CNT register. The following is an undocumented hack which will accomplish the equivalent of a reset of the CNT reg...

Will the ADC windows whatchdog mode work for waking up a device?

Hi!I would like to know if there is any chance on waking up a STM32L0 (from stop mode) with an ADC in windows whatchdog mode. Probably the ADC won't operate in that mode. because of the clock. Or the ISR source won't wake the CPU.

STM32L4S PLL accuracy with the HSE clock

I want to feed the HSE clock (sourced by a 4MHz oscillator) to the PLL to create a SYSCLK at a higher frequency. Is there accuracy information on the PLL or is the accuracy of the output clock driven by the external oscillator? I've checked the data ...

I using stm32l4 in low power mode and wants micro counts of input gpio pulses.I attached the explanation and the code.
