Hi,
I have two kernel modules, one for sending and one for recieving, on two
different machines. The two interesting functions, after creating the
sockets and connecting to them, are basically:
static void recieve(void *arg)
{
int retval;
char packet[sizeof(float)];
retval = rt_dev_recv(sockfd, packet, sizeof(packet), 0);
*((hal_float_t *)hal_data->hfloat) = *((float *)packet);
}
static void send(void *arg, long period)
{
int retval;
char packet[] = "2.9";
retval = rt_dev_send(sockfd, packet, sizeof(packet), 0);
}
In recieve, hal_float_t is a volatile float.
First off, is it true that I can only send a char array? Or could I send
over a float directely?
If I now monitor the value of hal_data->hal_float, I get a strange value.
I know I'm doing something wrong here on programming level, probably in
casting. Any idea what that might be?
Thanks a bunch,
Evert
