For single-chip microcomputers, GPIO is often used. Here, an oscilloscope is used to test the IO flip rate to see how fast it is.

The manual gives some characteristics of GPIO

Directly flip GPIO programmatically

Measured with an oscilloscope

The measured GPIO flip frequency under default conditions reaches 5MHz, and the IO characteristics are very good

I saw the parameters are at least 50M, but the actual measurement is only 5M. Maybe I didn't understand the parameters.

The N32G430 GPIO has only two modes of reversal speed, no specific
