arduino 使用String 替代不定长byte[]数组 使用串口传输hex数据时,常用byte[]数组接收数据,若预先不能知道将要接收到数据的数量,那么byte[]数组的长度很难处理。偶尔想到用String对象来存储串口传输hex数据应当很方便,经测试,非常成功。 测试程序: String hh="";voidsetup() {//put your setup code here, to ru...
String stringOne = String(analogRead(0), DEC); String stringOne = String(45, HEX); String stringOne = String(255, BIN); String stringOne = String(millis(), DEC); 2、字符串的连接与追加,官方将两种功能分开了,其实觉得和在一起对比理解会更好一点 1 2 3 4 5 6 7 8 stringThree = string...
