What does FifoFillCondition do?
If set to “0”, the received data will be stored in the FIFO only after a Sync detection has occurred. This is the default and useful setting
If set to “1”, the FIFO will fill up with anything as soon as the receiver is turned on and ready to receive. This is more of a debug mode option
Thanks Sebastien. That was helpful. . . I’m new to the RFM69 and I want to understand it better, but I’m having a hard time “connecting the dots” using the manual. Would you have something for beginners like me? Maybe a timing-diagram showing the relationship of the various signals available to the uC?
