Serial.begin(115200);...and in the IDE you leave it at the default of 9600.For the Arduino it sends data at a period of 8.6us (1/115200). If there are 10 bits transmitted then its complete in 86us. The ide will not even see the bits as its receive period is 104us. Well, it...
In the program below, the very first thing that you do will in the setup function is to begin serial communications, at 9600 bits of data per second, between your board and your computer with the line: 在下面的程序中,在设置函数里第一个要做的事情就会开启串口通信,以 9600 bps,使用下面的代...
