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

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.
