From: Daniel Ragonesi on 4 Aug 2010 10:21 Can I send a command through RS-232 only when the program stops? I need to send a command to stop data flow. I currently do a similar thing to start the data flowing. I need to send the command once at the beginning. To do this I have the command connected to a switch block. The middle switch in connected to a 0 'Constant' block through a 'Send Command Once Block'. The bottom of the switch in connected to a 'Ground'. Is there any way, possibly using CallBack StopFcn to send a command at the end? -Dan Ragonesi University of Delaware |
