我们看一下怎样把联合体和EEPROM.write和EEPROM.read进行结合实现浮点型变量的读写操作: 通过前面8个小灯的实例和这个实例,可以发现,联合体有两个元素,一个像是容器一样,小灯的字节变量all,第二个实例的浮点型f,另一个像是容器变量的最小单元,比如字节变量all对应的是8个单bit位的定义,浮点型变量对应的是4个...
Serial.write and Serial.print do not block. Older versions of Arduino would wait until all characters were sent before returning. Instead, characters that you send using Serial.write or Serial.print (and println) are transmitted in the background (from an interrupt handler), allowing your sketch...

将write()方法与字地址和要存储的值一起使用。地址必须是介于零和EEPROM.length() - 1之间的值,它告诉MCU在哪里存储值。 read()方法 以下示例从EEPROM中读取一个字节: #include void setup() { Serial.begin(9600); int word_address = 0; byte value; ...
Serial.begin(9600); while (!Serial) { ; // wait for serial port to connect. Needed for native USB port only } } void loop() { // read a byte from the current address of the EEPROM value = EEPROM.read(address); Serial.print(address); ...
