Multi function event recorder of the 5th National Games of the Blue Bridge Cup
2022-07-06 02:07:00 【Miseñor】
I feel this session is too difficult , Almost all of them are used （ Except ultrasound ）, But the serial port is still not very good at writing , The function is written , But it doesn't run in the main function . And I don't know why , Photosensitive that becomes 03 The passage , It's weird , It's completely opposite to the previous .
