STM32F100 RTC Issue
Posted on April 05, 2017 at 19:45Hello All,We are working on RTC. We use:MCU: STM32F100C6T6IDE: IARCode Generator: STM32CubeMxHardware:-> Connect external 32.767 KHz crystal-> 3.3 Coin Cell to VBat PinSoftware:-> RTC Config: LSE 32.767 KHz-> Time an...
reduce power consumption on STM32F413ZH
Posted on April 05, 2017 at 11:38Hi allAccording to en.DM00244518.pdf page 22We could use +3.3V as power supply only in situation ''ST-LINK not powered''.My question is when I use E5V, if I remove SB3 and SB111, the st-link part will not be powered....
I2S with DMA 24 bit in 32 bit frame
Posted on April 05, 2017 at 16:15I'm using the STM32F4 with a 24 bit ADC that uses I2S 24 bit in 32 bit frame. I'm using the DMA to transfer the samples to memory, but I'm kind of confused on how the data is stored. Is the data stored like this? L =...

Stm32CubeMX change to systick priority cause hardware failure
Posted on April 05, 2017 at 16:45Hi, I'm using stm32CubeMX v4.20 and after changing systick priority to 15(lowest) my project runs into hardware failure. If i changed back to zero, problem disappears. Any Inside on why?best regards,Tony
STM32L431 COMP erratum
Posted on April 05, 2017 at 12:04On the STM32L431, there's an erratum described in STM32L431xx Errata sheet (STM32L431xx device limitations / DM00218224). It allows to reset COMP1 and COMP2 despite of the LOCK bit being set.My question: What happens...
STM32F411CEx RTC drift with LSI RC clock
Posted on April 05, 2017 at 16:20Hi,We are using STM32 internal RTC with 32.768 KHz LSI RC clock. We are observing very large drift in time(Approx 3min lag in 1 Hour).We have gone through the RTC calibration application note.But that requires manual...
