If you use it, you can directly use wirte_to_flash to write or read_to_flash to read, and the test is effective.

The code in this blog is based on other bloggers, but since I didn’t record the blogger’s URL later, I didn’t specify it. If the original blogger troubles you, you can send me a private message. I will add where I came from later. thank.
