如果要将此应用项目移植到开发板上，只需要根据此项目的电路图修改管脚，改成我们开发板按键和LCD及蜂鸣器对应的管脚上，AD芯片使用的都是一样的，所以只需要将检测AD通道换成AIN3通道，也就是修改程序内通道的口即可。具体怎么修改通道口，参考基础实验例程内AD实验视频。(If you want to transplant this application to the development board, just modify the pin according to the circuit diagram of the project, change it to our development board key and the LCD and buzzer pins. The AD chip is the same, so only need to change the AD channel to the AIN3 channel, that is to modify the channel inside the channel. How to modify the channel port specifically, refer to the AD experimental video in the basic experiment routines.)
