TelosB UART/SPI[0] sharing among CC2420 and other devices #2

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Init CC2420 radio 
2. Init UART[0] for communication to other devices (eg, RFID reader or GPS)
3. Try radioSend() - it fails, as SPI/UART bus is configured in UART mode

Workaround: User must explicitly call USARTInitSPI(0)

Probable better solutions: 
* implement radioReInit() function
* allow to call radioInit() multiple times
* automatically arbitrate data bus when calling radioSend() and 
UsartEnableRX/TX()

Added (temporal) workaround: allow to call cc2420_init() multiple times
