Hi Julien,
try:
typedef struct MyCommand {
uint8_t flag;
uint8_t length;
} MyCommand;
MyCommand Cmd1;
And set the value (Cmd1.flag = 0;) in an "executable environment" (e.g.:
function, event, command), because otherwise the complier thinks that "Cmd1"
is a interface with the command "flag".
I think you don't have to use '0' for the assignment, just 0 or FALSE
without the apostrophe.
Don't use "command" as an identifier, because it is already a nesC keyword.
Also take a look at http://nescc.sourceforge.net/papers/nesc-ref.pdf
(Language Reference Manual from Phil Levis)
Regards,
OLE

Betreff: [Tinyos-help] struct type
I am trying to set a value to an uint8_t type in a structure. i wrote it the
C way:
struct Command
{
uint8_t flag;
uint8_t length;
};
struct Command Cmd1;
Cmd1.flag = '0';
but at compiling it says that
ReaderControllerM.nc:52: unexpected interface reference in declaration of
`Cmd1.
flag'
What does it mean? How to give a value to a byte in tinyos in general, and
what are the types? I am actually trying to go a bit further with the struct
and do something like this below, but since i am already stucked with a
simple one...:
struct Command
{
uint8_t flag[2];
uint8_t length[4];
};
thanks guys.
