Doubts on Nucleo-H753ZI

I'm interfacing Nucleo-H753ZI with DAC8775EVM through SPI4. DAC8775EVM works on logic HI in range of 5V and expects the same logic from Nucleo-H753ZIbut Nucleo-H753ZI MCU itself runs at 3.6V so Logic Hi isn't read by DAC8775EVM.How to Change the logi...

STM32F405: Can we use Port A0 (T2.1-ETR or T8 ETR) to trigger a capture on Port A5 (T2.1-ETR or T8.1)?

When we enable the RTC feature on our controllers, we do a calibration in Production against a GPS-locked 10MHz signal. Usually, we'll use the T2 ETR to clock the 10MHz signal in and an RTC-generated 1Hz signal on one of the other T2 channels such a...
