This example demonstrates the advanced serial printing functions by generating on the serial monitor of the Arduino Software (IDE) a table of characters and their ASCII values in decimal, hexadecimal, octal, and binary.
Hace 1 día · Constructing a String from a number results in a string that contains the ASCII representation of that number. The default is base ten, so. String thisString = String(13); gives you the String "13". You can use other bases, however. For example, String thisString = String(13, HEX);
What you are attempting to do is a conversion of hex string to byte. For that you have to determine if you are scanning left to right or right to left. After that convert a char in the string to a half byte.
