如:BIN(binary, or base 2), OCT(octal, or base 8), DEC(decimal, or base 10), HEX(hexadecimal, or base 16) 。 返回值:size_t:print() 返回写入的字节数,但读取该数字是可选的。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 Serial.print(78, BIN) gives "1001110" Serial.print(78...
Serial.println("In DEC:"); Serial.println(tmp[1],DEC);//tmp[1] points to 'e' of the "hello world"delay(500); Serial.println("In HEX:"); Serial.println(tmp[1],HEX); delay(500); } } 演示如下: 上图中的 tmp[7] 是 "hello world" 中的 'o' (当然是第二个o了) 所以,十进制...

可选的第二个参数用于指定数据的格式。允许的值为:BIN (binary二进制), OCT (octal八进制), DEC (decimal十进制), HEX (hexadecimal十六进制)。对于浮点数,该参数指定小数点的位数。例如: Serial.print(78, BIN) gives "1001110" Serial.print(78, OCT) gives "116" ...

默认情况下,使用板载上拉电阻将所有3个地址输入均拉为高电平,使PCF8574的默认I2C地址为0111111 Binary或0x3F Hex。 通过短路跳线,地址输入被拉低。如果要短路所有三个跳线,则地址将为0x38。所有可能的地址范围从0x38到0x3F。请参考下图。 I2C LCD显示屏引脚排列 I2C LCD只有4个与外界连接的引脚。连接如下: 地线...
