Hi Lulu, I assume you are familiar with MIG. If it is not the case you should have a look at:
http://www.tinyos.net/tinyos-1.x/doc/nesc/mig.html http://docs.tinyos.net/index.php/Mote-PC_serial_communication_and_SerialForwarder http://www.tinyos.net/tinyos-1.x/doc/tutorial/lesson6.html I usually use Java, so I can not help you that much with the automatic functions generated by C. But I imagine that the mechanics may be familiar. In Java, a new class is automatically generated that includes both the corresponding methods for setting or getting each of the parameters of the struct that you are using as message. For instance, in your AMSender and AMReceiver you could use the channel AM_FROMANDTOPCMSG, which must be a valid constant likely defined inside an enum in your header. In the same header you may have the corresponding message type for this channel (e.g. something like typedef struct FromAndToPcMSG { int8_t values [10]; uint16_t command } FromAndToPcMSG; Now, using MIG you create the Java class with the methods (set_values_element, get_values_element, set_command and get_command) that will be called inside your JAVA program. After MIG just compile your JAVA program and run it in the corresponding serial port. Cheers!!!
