Thanks Michael, I'm able to compile and build now but I'm pretty sure the
command isn't sending successfully because I had toggle the yellow led if
it's unsuccessful and it seems to be toggling. Do you know what the
asterisk before the variables is for? Do you know what the problem is? Are
these warnings an indication my unsuccess in sending the byte?
NoCRCPacket's command:
command result_t txBytes(uint8_t *bytes, uint8_t numBytes)
My command call:
uint8_t initialDispHexValue = 0xFE;
uint8_t numBytes = 1;
// send message to UART (serial) port
122 if (call txBytes((uint8_t*)initialDispHexValue, (uint8_t)numBytes)
!= SUCCESS)
{
sending_packet = FALSE;
call Leds.yellowToggle();
}
132 if (call txBytes((uint8_t *)baudRateDispHexValue, (uint8_t)numBytes)
!= SUCCESS)
The warnings
C:\Crossbow\cygwin\opt\MoteWorks\apps\tutorials\myapp\MyAppM.nc: In function
`MyAppM$Timer$fired':
C:\Crossbow\cygwin\opt\MoteWorks\apps\tutorials\myapp\MyAppM.nc:122:

Subject: RE: [Tinyos-help] Utilizing a command from another module,
It's possible to provide/use commands directly, without them being part
of an interface, though I think it's a bit of a hack. You have just got
to get the wiring right.

Are you sure your app needs to provide the command? Usually, the top
level configuration neither provides nor uses anything.
To wire txBytes to your module:
> implementation {
> components Main, MyAppM, TimerC, LedsC, NoCRCPacket as NoPacket,
UART;
MyAppM.txBytes -> NoPacket.txBytes;
Should do the trick. Then inside the module:
> module MyAppM {
> provides {
> interface StdControl;
>
> }
> uses {
> interface Timer;
> interface Leds;
> interface StdControl as PhotoControl;
> interface SendUART;
>
> command result_t NoCRCPacket.txBytes(uint8_t *bytes, uint8_t
numBytes);
You shouldn't mention the NoCRCPacket here, just the command:
command result_t txBytes(uint8_t *bytes, uint8_t numBytes);
Then, call it as
call txBytes(...);
HTH,
Michiel
