#87936 - Poll Start - Poll Stop Commands Responding to: ???'s previous message |
I use a similiar process control an ICOM scanning receiver, with Windows, I simply send a command to change frequency and another to begin sampling, when I have enough samples, simply send another message to stop. It works well.
I would just say make sure that you have the Rx interrupt on your 8051 so you actually see the stop command come through, and as it is a slave device an Ack to the Start and Stop Messages is also a good idea, then the PC will know if it has to send multiple messages to your box if it missed the command.
