pinMode(2, INPUT_PULLUP);pinMode(3, INPUT_PULLUP);pinMode(4, INPUT_PULLUP);pinMode(5, INPUT_PULLUP); 下面的代码块用于在按下按钮时播放歌曲。它读取每个按钮的数字值,当它变低(零)时,它假设按钮被按下并通过调用所需的函数播放相应的音调。
The hardware of the SX126x chips can be designed to use either an internalLDOor an internalDCDC converter. The DCDC converter provides better current savings and will be used in most modules. If there are problems to get the SX126x to work, check which HW configuration is used and setUSE...
The internal pull-up will rise the signal to high, until a button is pushed and draws the line to ground.You can also connect the keys via 5V, but you need a pull-down resistor on the io side for a defined signal.If you have a key matrix you need up to 4 io pins for the ...
