Here's my code...
Follow comment...
case MainBtnUpButton:
{
if(SerialLink == false)
{
//Find serial ref num
ThisErr = SysLibFind("Serial Library", &SerNum);
if( ThisErr == 0)
{
//open serial port
SerErr = SerOpen(SerNum, 0, 9600L);
if(SerErr == 0)
{
StrCopy(toSend, "12345");
SerSend(SerNum, toSend, 5, errPtr);
SerialLink = true;
//everything work fine before here
}
}
}
else
{
SerClose(SerNum);
SerialLink = false;
//This makes a fatal exception
}
break;
}
case MainBtnDownButton:
{
if(SerOpen(SerNum, 0, 9600L) == serErrAlreadyOpen)
{
StrCopy(toSend, "yeah");
SerSend(SerNum, toSend, 5, errPtr);
//this make a fatal exception
}
break;
}
why is the first time I open the serial link I can send data
( and they are received on the pc )
and not the second time or when i use the DownButton??
Do you see something wrong with my code ???
