Arduino library to print to a char array.DescriptionPrintCharArray is a class that implements the Print interface and an internal char array. It will effectively buffer a number of print statements and allows it to be printed or processed (for real) later. The internal buffer can be set in...

结构体所有元素的内存是独享的,char 数据类型占用1个字节,float 数据类型占用4个字节,那定义了结构体后,结构体占用的空间就是5字节(上左图),而联合体不同,定义了联合体后,联合体内元素占用的空间是共享的,以占用空间最大的元素为基准作为联合体的占用空间,例如上面float是4个字节比另一个元素char占用一个字节多...
