Question
I cannot set the pin name as “1pin”.
Answer
The pin naming has the following restrictions:
- The characters that can be used are letters and numbers (a-z, A-Z, 0-9) and the underscore (_).
- The first character of a name must be a letter (a-z, A-Z) or underscore (_).
“1pin” cannot set as pin name because it is started with a number.
