Max voltage on pins when unpowered?

Hello,I notice in the STM32G030x6/x8 datasheet, Table 18 that the max input voltage on FT_xx and any other pin are VDD + 4V and 4V respectively. Does this mean those pins can be safely driven with 3.3V when the MCU is unpowered?Thanks,Nicholas

Resolved! RTC Reference Clock (50Hz) worsens the LSE accuracy

As indicated by an4759, I am trying to use the 50Hz mains reference to improve the RTC accuracy of an STM32F413ZH.However, the results I get are much worse than without using the reference:LSE only: 0.6s/dayLSE+50Hz: 7.5s/day (test duration 4 days)Ac...

ADC on ST Nucleo H743ZI board with DMA on Zephyr platform.

Hai, I am working with ST Nucleo H743ZI board for analog-to-digital conversion without CPU intervention between samples, by using DMA in Zephyr platform. Is there any ready-made example for the above, that I can refer?Thank you. Sachin
