[Oberon] FPGA - nRF24L01 connection

[Tomas Kral]

Hi,

As advised by Paul, I have tried carrier test example, as I am still
unable ping payloads between RPI and Oberon.

On RPI, I run a simple example `RF24' program, it steps through all 126
channels, and listens for 128us in each, incrementing carrier count
if detected any on that channel.

On Oberon I just execute `NRF.Ping' command, that just tries to send
32 byte payload over the wireless.

Carriers detected in channels, are reported as a single hex digit
From left to right, 0..126

On channel 5, SW := {1,0,0,0,0,0,0,0}; 
000033400000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000

0000123000000000000000000000000000000000000000000000000000000000000000
00000000000000000000000000000000000000000000000000000000

On channel 85, SW := {1,1,1,0,0,0,0,0};
000000000000000000000000000000000000000000000000000000000000000000000000000000000000321000000000000000000000000000000000000000
000000000000000000000000000000000000000000000000000000000000000000000000000000000000123000000000000000000000000000000000000000
000000000000000000000000000000000000000000000000000000000000000000000000000000000000435000000000000000000000000000000000000000

I am surprised to see that signal carrier is detected in the spectrum
of channels, 4,5,6 and 84,85,86 with similar count???

Many thanks for any insight.
