Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
Hi, I'm using STM32L452, and i need to get the time and date from RTC. The RTC works fine, but when i enter in standby and check the time after wake up (via RTC), the RTC only incrment durring the waked time, and doesn't count the time durring standb...
