RFM12B clear interrupt

[dwenrhod]

Having trouble converting from polled to interrupt driven receiver code.

When the transmit message is complete, I cannot clear the IRQ pin by reading all the bytes in the FIFO.

Seems like the RX might be triggering on noise.

Why bother?
What library are you using?
There is a RFM12B library here, it does everything for you.
