STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
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....
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 =...

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
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...
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...

Posted on April 05, 2017 at 13:12Hello,I want to read multiple adc channels, using STM32F070 MCU my IDE is Coocox. I am searching for relevant examples without DMA but not able to find. Any help in this regard would be appreciated.Regards,Muhammad M...
Posted on April 05, 2017 at 12:42Looking at the STM32F767xx Datasheet (DocID029041 Rev 4), the SRAM1 address is listed as 0x20020000.But the STM32F76xxx Reference Manual (DocID028270 Rev 2) lists this as 0x20010000 in several places: Page 98/1896: ...
Posted on April 05, 2017 at 13:43Hi,Over the past ~18 months we have made an stm32F405 based logging device. Data is gathered and stored to SD card, when USB is plugged in, the SD card is 'owned' by the Mass Storage Device implementation that we got...
