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...
首先定义一个函数hexToAscii()，其功能是将输入的16进制字符串转化为对应的ASCII字符串。该函数中，hexCharToDecimal()用于将16进制字符转换为整数，hexToAscii()函数则通过遍历输入的16进制字符串，获取每两个字符表示的16进制数。通过位运算将高低4位合并为ASCII字符，最终得到的ASCII字符串存储于ascii数...

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" ...
