Hi All,
Hi All,
I have a struct to send data through serial port.
My java application works fine sending data to mote, but I'd like to
use a C language to do this.
I know that in the makefile we have the mig to generate my
StructMsg.java, but what should I
do to generate it in C?
I took the struct in the C file, but it doesn't work. See the code below.
#define DEVICE "/dev/ttyUSB1"
typedef struct data_id_serial_msg {
char data_id[BUF];
} data_id_serial_msg_t;
data_id_serial_msg_t data;
int mote_fd = open(DEVICE, O_RDWR, 0);
if (mote_fd == -1) {
perror("mote - open device");
}
teste = &data;
while(1) {
idx++;
for (k = 0; k < BUF; k++) {
teste->data_id[k] = idx;
}
write(mote_fd, (void*)teste, sizeof(data_id_serial_msg_t));
sleep(2);
}
What is wrong? Is there a header?
Thanks all
Daniel Patrick
