F5438 seems to be better than F5529. Because I used G2553 to write programs before, but I didn't use the IO port for a long time, so I want to try other chips....
My stm32 system uses an 8M external passive crystal oscillator. When the system starts running, I can see a stable waveform with an oscilloscope. But after running for a few minutes, the waveform will...
