When we refer to a C data type, we are referring to the attributes that a piece of program data has. As you will learn, certain data types are better suited to specific tasks than other data types, even though more than one data type might work. Selecting the right data type often ...
无涯教程-Arduino - 数据类型 C变量的类型决定了它在存储中占据多少空间以及如何解释所存储的位模式。 下表提供了在Arduino编程期间将使用的所有数据类型。 void 类型 void 仅在函数声明中使用,表示该函数应不返回任何信息。 Void Loop ( ) { //其余代码 } 1. 2. 3. Boolean 布尔类型 布尔值包含两个值之一...
BLE.gatts_write(value_handle, data) 把数据写入到本地,客户端通过value_handle可以读取本地的数据 BLE.gatts_notify(conn_handle, value_handle, data=None, /) 发送通知给某个(conn_handle)连接的客户端,如果data设置的None,那么就把本地当前的值发送出去(通过gatts_write可以把值写入到本地),否则,如果data...
