Fifo in RX is always empty, I don't use IRQ0 and IRQ1 for the moment. |

Without looking at all the code...a couple of 'low level' questions...
1) do you have the correct power for the devices ? Most 'peripherals' are 3 volts these days...have you enough current to power it as well ?
2) can you actually set and read various registers of the device for both xmtr and rcvr units ??

So voltage is 3.3V
after some small issue I check that I can read and write configuration on each.
but still no RX.
I change:
#fuses INTRC_IO
and
output_low(RESET); // reset pin |
