[liklon plays with GD32F350] 5. RTC clock
In the subsequent development, a calendar is needed, so debug the RTC of GD32.According to the actual board, these two crystal oscillators are not soldered, so the RTC clock source can only be the int
Learning is automatic behavior
If someone always teaches you, you will never learn. --Bernard Shaw I experienced this test and I have a deep understanding of it. Learning is an automatic behavior. If you don't force yourself, it's
