Wire.begin(地址) - 地址是7位从地址。 Wire.onReceive(收到的数据处理程序) - 当从设备从主设备接收数据时调用的函数。 Wire.available() - 返回Wire.read()可用于检索的字节数,应在Wire.onReceive()处理程序中调用。 示例 #include <Wire.h> //include wire library void setup() { //this will run ...
对于IIC总线的使用,Arduino IDE自带了一个第三方类库Wire。 2.1 常用函数 2.1.1 begin() begin()函数有4个重载: // 如果i2c总线初始化成功,返回true bool begin(int sda, int scl, uint32_t frequency=0); bool begin(uint8_t slaveAddr, int sda, int scl, uint32_t frequency); // Arduino主流API...
rdata=Wire.receive(); }returnrdata; }///Returns number of bytes read from device///Due to buffer size in the Wire library, don't read more than 30 bytes//at a time! No checking is done in this function.///TODO: Change length to int and make it so that it does repeated//EEPRO...
