Hi to all,
I have tinyOS 2.1 and I use nesc to program telosb mote.I must use usart0 to
make receive/send from a device and in the same time I must write on flash and
I must hear lan radio for receiving packet.I have read TEP 108 about resource
Arbitration and I know that I have to use arbiter .I am studying the example
testfcfsarbiter and testroundrobinarbiter in apps/tests/arbiter and I am
understanding only in part .On telosb uart0 ,flash and radio bus is one bus.
How to connect :
components CC2420ControlP as rete;
components new Msp430Uart0C() as Seriale0;
components Stm25pSectorC as disco;
to arbiter ?
For the moment I do :
#define TEST_ARBITER_RESOURCE "Test.Arbiter.Resource"
configuration TestFcfsArbiterAppC{
}
implementation {
components MainC, TestFcfsArbiterC as App,LedsC,
new TimerMilliC() as Timer0,
new TimerMilliC() as Timer1,
new TimerMilliC() as Timer2,
new FcfsArbiterC(TEST_ARBITER_RESOURCE) as Arbiter;
components CC2420ControlP as rete;
components new Msp430Uart0C() as Seriale0;
components Stm25pSectorC as disco;
enum {
RESOURCE0_ID = unique(TEST_ARBITER_RESOURCE),
RESOURCE1_ID = unique(TEST_ARBITER_RESOURCE),
RESOURCE2_ID = unique(TEST_ARBITER_RESOURCE),
};
App -> MainC.Boot;
App.Resource0->rete.Resource;
App.Resource1->Seriale0.Resource;
App.Resource2->disco.ClientResource[1];
App.Resource0 -> Arbiter.Resource[RESOURCE0_ID];
App.Resource1 -> Arbiter.Resource[RESOURCE1_ID];
App.Resource2 -> Arbiter.Resource[RESOURCE2_ID];
App.Timer0 -> Timer0;
App.Timer1 -> Timer1;
App.Timer2 -> Timer2;
App.Leds -> LedsC;
}
but I have the following error :

what I must to do to use correctly the arbiter to use radio,flash and uart0 in
multiplexed way ?
Thanks in advance
