Description:
|
|
|
|
A generic interface for executing OLPC Embedded Controller commands and
|
|
reading their responses.
|
|
|
|
To execute a command, write data with the format: CC:N A A A A
|
|
CC is the (hex) command, N is the count of expected reply bytes, and A A A A
|
|
are optional (hex) arguments.
|
|
|
|
To read the response (if any), read from the generic node after executing
|
|
a command. Hex reply bytes will be returned, *whether or not* they came from
|
|
the immediately previous command.
