Hello,
Could someone please tell me how to stop CC2420 radio in telosb while
allowing other components to continue working? At some point in my
program, I stopped the radio by calling CC2420's StdControl.stop()
before posting a task to write the flash, but it seems the writing was
not successful. I guess it's because some components are stopped as
well in CC2420's StdControl.stop(), for example, TimerC's StdControl.
So I'm wondering if there is a way to precisely stop the radio alone?
I am still using TinyOS-1.x. Thanks.
It's probably disabling the SPI bus. The easiest way to get around
this is to stop() the radio, then start() the flash chip. I think the
flash start() will reactivate the SPI.
