Project talk:Alpha transceivers

0xfe00 = software reset

SPI = rising edge, 16 bit

Interrupts (nIRQ low) for:

when in appropriate mode: RGIT (TX register ready for data) RGUR (TX register underrun) FFIT (RX FIFO has data) FFOV (RX FIFO overflow)

POR (power-on reset) WKUP (wake-up timer) EXT (nINT) LBD (low battery)

SDO runs all the time.

Have you looked at http://www.seeedstudio.com/depot/datasheet/RFBee%20User%20Manual%20v1.1.pdf?

The design leaves lots of digital pins free on the AT Mega (which uses the Arduino bootloader) which I reckon would suit most applications and the CC1101 is cheap. Been thinking of trying to reproduce this on a breadboard using their design and firmware + regulator hardware.
