|
|
* The Commodore based Contiki targets all have a special character
|
|
* encoding called PETSCII which differs from the ASCII encoding that
|
|
* normally is used for representing characters.
|
|
*
|
|
* \note For targets that do not use PETSCII encoding the C compiler
|
|
* define WITH_ASCII should be used to avoid the PETSCII converting
|
|
* functions.
