ASCII table

Connect to the Maple Serial using the Serial Monitor, then press
|
|
any key and hit enter.
|
|
|
|
Prints out byte values in all possible formats:
|
|
* as raw binary values
|
|
* as ASCII-encoded decimal, hex, octal, and binary values
|
|
|
|
For more on ASCII, see:

|
|
|
|
No external hardware needed.
