Hi, because of the difference in architecture between PC and motes, even between motes, you cant cast the message payload to your struct because in the mote the struct will have a size and padding different than it will or could have in PC platform. So here is why MIG is usefull, you make your message based on tmsg_t and fill the fields of your struct using the functiones provided in the .c file. The same way you read the fields of your struct inside the tmsg_t with the functions provided to read or get.
hope this help. -Bill On Fri, Jan 1, 2010 at 12:47 PM, Echedey Lorenzo <eche...@gmail.com> wrote: > Hi friends, > > I want to use the same *nx_struct* that I use in my telosb sensorial > application in my C based listener where I record all the received data: > > *mig c -c-prefix=TELOSBAPP_H -target=telosb Telosbapp.h mystruct_t -o > OUTmystruct_t.h > * > > So I get two files, one .c and one .h with an enum and some functions to > get and set data in the structure.
