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. |
