Hi,
I don't know why you want to use string but I don think that it is a
good idea.
If you want to use it for sending commands, I recommend you to use
numeric constants, this is faster, easier and it saves resources. You
declare them with enum and dont have to worry about their representation
(byte).
If you want to use commands like "read" for example you use 4 chars ( 4
bytes ) where you can use only one by defining a constant using enum{
READ };
using that representation and designing correctly your packets you don't
have to parse a string.
Like
typedef nx_struct packet_t {
nx_uint16_t commandCode;
nx_uint16_t commandParam1;
...
} packet_t;
and instead of doing something like strcmp you can use a switch
switch( packet.commandCode )
{
case READ:
...
case SEND:
...
}
If you still want to use string, I think you can code string
manipulations methods by yourself if you don't find a nesc library to do
that (I don't know if it exists), but again I think it's too resources
consuming for a very limited efficiency.
Regards
