Since flush_rx was removed from startListening, this provides an option to flush the RX buffer in use cases where this is required.
The original #if was meaningless becasue it would always eveluate as true becasue LITTLEWIRE was already handled in an #elif above. This change allows the Tiny to still be able to use 3 wire mode, but arduinos can use a 4 wire mode, which uses CSN but not CE (CE always held high). Previously on an arduino if the CE and CSN pins were set to the same pin, then CSN pinmode was never set due to this IF

@soligen2010 If I had to chose between the 2 different 4-pin implementations, I'd go with #387 as it focuses on less power and the ATTiny85. The Arduino boards have plenty of pins to spare for this transceiver, so I'm not sure about the relevance for this "one line fix". |
