hello everybody........
In MICA2, the interface between CC1000 and the atmel is through SPI. Its having just two pins.... i.e) DIO and Dclk. Its said that DIO is bidirectional.Its obvious that the controller is master (thats what i feel............:D ). Say when the CC1k is in transmit mode the it should be in MISO and when in receive mode it should be in MOSI.
my first question is what makes the DIO pin of CC1k to be as an input/ouput?
2) in tos/platform/mica2.......... HPLSpiM i find something called
TOSH_MAKE_SPI_SCK_INPUT();
TOSH_MAKE_MISO_INPUT(); // miso
TOSH_MAKE_MOSI_INPUT(); // mosi
where is the code for these...............? and what does SpiByteFifo.initSlave() exactly do................. ?
