在 Arduino 上将整数/十进制转换为十六进制? [英] Convert integer/decimal to hex on an Arduino?

问题描述

如何将整数或十进制变量转换为十六进制字符串?我可以做相反的事情(将十六进制转换为整数)，但我想不出其他方式.

How can an integer or decimal variable be converted into a hex string? I can do the opposite (convert hex to int) but I can't figure out the other way.

这是用于数组中的 Serial.print() 十六进制值.

This is for Serial.print() hex values in an array.

推荐答案

查看 Arduino String 教程 此处.下面的代码取自该示例.

Take a look at the Arduino String tutorial here. The code below was taken from that example.

// using an int and a base (hexadecimal):
stringOne =  String(45, HEX);   
// prints "2d", which is the hexadecimal version of decimal 45:
Serial.println(stringOne);  

该页面上还有很多其他示例，但我认为对于浮点数，您必须自己动手.

There are plenty of other examples on that page, though I think for floating point numbers you'll have to roll your own.
