[Oberon] FPGA - nRF24L01 connection

[Tomas Kral]

Hi,

I think I have done, best I could to set parameters to match
`SCC.Mod', I should think. I now use `RF24' linux(RPI) generic
examples, as `MySensors' gateway abstracts from it and uses specific
sensor messages, different to Oberon.

I have coded simple ping/pong procedures in Oberon, and I run similar
in c++ on RPI.

It should send payloads with header back and forth, but still nothing
received at either end!!!

`SCC.Mod' never sets RX_ADDR_P0,1 for pipes 0,1 nor TX_ADDR, which I
do not understand???

In the RPI `RF24' example code, I set pipe 0,1 addresses to reset
defaults.

const uint64_t pipes[2] = { 0xE7E7E7E7E7LL, 0xC2C2C2C2C2LL };

Also I set these to match `SCC.Mod'

// Setup and configure rf radio
  radio.begin();
  radio.setChannel(5);
  radio.maskIRQ(1,1,1);

// optionally, increase the delay between retries & # of retries
  radio.setRetries(50,50);

// Dump the configuration of the rf unit for debugging
  radio.printDetails();

I need help, as I have very little understanding of it.
Many thanks in advance.
