The problem is, that if i send data via printf through the Serial Interface to the computer, i am able to receive it as sended. On the other hand the PC-to-Mote Communication does not work. The RX LED light up, but

问题 I'm studying THIS tutorial for tinyos and I wanted to try it out. I try to create the packet but it gives me the following error. I don't know what's wrong. It is probably something simple but I can't figure out what it is. #include "TestMsg.h" ... event void AMControl.startDone(error_t error) { if (error == SUCCESS) { call Leds.led0On(); //create packet TestMsg_t* msg = call Packet.getPayload(&packet, sizeof(TestMsg_t)); msg->NodeID = TOS_NODE_ID; // // //TODO in the meantime this can change

问题 i use customer message and send it broadcast over radio channel, i use example 6 ( CounterSend ) from this link . when i build this project as micAz on mote 1, after this i use Xsniffer (TOSBase) on the mote that i will use it on the serial usb board (520). after that i open Xsniffer program to see the radio packet and they appeared as following : on other hand, to use Xserver i use XMeshBase then type on cygwin terminal : xserve -device=com4 i got this!! but i can't understand what it

问题 I have a pattern that is basically some boilerplate code with a part that varies in the middle if(condition){ struct Foo m = start_stuff(); { m.foo = bar(1,2); m.baz = 17; } //this part varies end_stuff(); } Is it OK to make a macro taht takes that intermediate code block as an argument? The rules for macro expansion in C seem awfully complicated so I am not sure if there aren't any corner cases that could come and bite me in the future (in particular, I don't understand how the macro
