How to Convert ASCII to Char in Arduino Hand Tools for Fun
1 Answer Sorted by: 3 A char is really just a number, which can be seen as a character using the ASCII table. See the reference. The ASCII value you want to get is already in your char b. If you really need an integer, you can use this: int b_ascii_value = b; But a char will probably be enough.

A data type used to store a character value. Character literals are written in single quotes, like this: 'A' (for multiple characters - strings - use double quotes: "ABC"). Characters are stored as numbers however. You can see the specific encoding in the ASCII chart.

00010000 is the binary code for ascii char 16 if I understand this right. No. 00010000 is the binary value 16. If you try to interpret it as ascii then it would be an unprintable character (Data Link Escape character). If you want to be able to send data fast, then you need to forget ascii.

Numeric and Character Encodings Introduction to Programming
Remember to adjust the size of your char array according to the largest value you expect to convert, and ensure that the converted value fits within the specified range for a char.. Convert an int to a char Using the itoa Function in Arduino. The itoa function is a handy utility available in Arduino that stands for "integer to ASCII". It allows you to convert an int to a character array.

Step 1: Character to Integer To convert a character to an integer you use this short statement: int a; char b; a=b-'0'; That's it! Ask Question Step 2: Integer to Character This is more intricate than the last one. However, it is not as difficult as some (including me before I learnt how to do it) might think. Here is the code: int a=1; char b [2];

Description Prints data to the serial port as human-readable ASCII text. This command can take many forms. Numbers are printed using an ASCII character for each digit. Floats are similarly printed as ASCII digits, defaulting to two decimal places. Bytes are sent as a single character. Characters and strings are sent as is.
