USBascii Example for Arduino 1.6.0rc1 on the Maple Mini STM32 platform
|
|
Sketch uses 13,572 bytes (12%) of program storage space. Maximum is 108,000 bytes.
|
|
Global variables use 2,600 bytes of dynamic memory.
|
|
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.
