I'm making VI which is supposed to communicate with an external device. It should send a message every 60s and recieve a message every 256ms. In order to accomplish this I've tried to make a loop in which two events reoccur at different frequencies. First I did this as the included test program blink2.vi where two LED:s flash at different frequencies. Then I made the also included library ET_loop.llb where messages are sent and recieved based on the time synchronization principle of blink2. It almost works, but it has some problems. First of all, the stop button, which works perfectly in blink2.vi doesn't work at all. Second, I get an error in two lower wire reading: Error -1073807252 occurred at VISA Read in SerialPortControl.vi->readVISA2.vi->Getstring2.vi->ET_loop.vi->Main_control_sequence.viPossible reason(s):VISA: (Hex 0xBFFF006C) An overrun error occurred during transfer. A character was not read from the hardware before the next character arrived. Any suggestions?

Double frequency loop with elapsed time.

I made this attempt at introducing a timed loop (I suppose the loop rather than the sequence is appropriate, but I'm not really sure). What should I wire to the break node?
