ENC28J60 Ethernet gateway

[kimot]

ENC28J60 for a stable gateway is not a good idea.
Buy some Wiznet...

[Sergio Rius]

So after being unable to make the nrf24 to work with the ENC28J60, I'm trying now something different. I started by making an rfm69 serial gateway with success. :clap:

Then I want to see if it could be possible to convert it to ethernet with the ENC28J60.
I searched and found everything in the forum. I arrived to the conclussion (that is probably wrong) that I must wire both radio and eth module using the same spi pins, activating a new driver and nothing more. But this doesn't work on the proto-board.

There's something else to be done? Thanks.

@Sergio-Rius
unfortunaly I can't help with your enc28j60 issue. and I'm not sure to have one for testing this.

A while back, we checked w5100 module + arduino 328p. Eth module and radio were working on same hw spi bus but in docs it uses softspi, I don't remember why, perhaps for having a dedicated spibus for ethernet..
I understand this is not very convenient to find the infos, when always more hw is supported.

Just a note, as you are using a Nano for your tests, RFMs modules are not 5v tolerant in theory, even if they seem to handle it, datasheet says 3.9v for max. good to know. but maybe you're already using a level converter.

@scalz Thanks for your help. Unfortunately I can't get a w5100 in my country and would order it outside. I had those rfms for years and I want to test range before buying a sensebender.
And I'm convinced to stop using the wifi for a gw.

I had hope that any used had the same hw already running.

@kimot I am use one Ethernet gateway about 2 year - work good and stable.

[Sergio Rius]

@cabat Could you please share you pinout for radio and module, and the sketch configuration?
I can't make it work and I don't know if it's a matter of connections or something to activate, like softspi.

@sergio-rius Pinout as described here Building an Ethernet Gateway, i am use module like this:

and my sketch on 20-Feb-2019 is:

#define MY_BAUD_RATE 9600

// Enable debug prints to serial monitor
#define MY_DEBUG

//#define MY_RADIO_RFM69

// When ENC28J60 is connected we have to move CE/CSN pins for NRF radio
#define MY_RF24_CE_PIN 5
#define MY_RF24_CS_PIN 6

// Enable gateway ethernet module type 
#define MY_GATEWAY_ENC28J60

//#define MY_CONTROLLER_IP_ADDRESS 192, 168, 178, 254   
 
// The MAC address can be anything you want but should be unique on your network.
// Newer boards have a MAC address printed on the underside of the PCB, which you can (optionally) use.
// Note that most of the Ardunio examples use  "DEAD BEEF FEED" for the MAC address.
#define MY_MAC_ADDRESS 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED

// Flash leds on rx/tx/err

// Set inclusion mode duration (in seconds)
//#define MY_INCLUSION_MODE_DURATION 60 

// Digital pin used for inclusion mode button
//#define MY_INCLUSION_MODE_BUTTON_PIN  3 

//#define MY_DEFAULT_ERR_LED_PIN 7  // Error led pin

It may have been fixed by now, but originally the W5100 did not release the SPI bus properly. So, it needed a separate SPI bus from the radio.
I think this was fixed in the W5200 and W5500.

[scalz]

@nagelc
exactly, you're right! Better memory than me :) I remember now, I had to hack w5100 lib for spi transactions to make it working on same bus. So I don't know if it has been fixed.. I hope so.

Noooooo..... Just ordered a W5100 :sob:

@cabat It may not do for me. I'm trying to use rfm69 now. I could not leave my existing network down and brought the nrfs back to where they belonged.

Also the eth module I have here is the shield for nano one. As it stacks below the nano, it may be that is interfering more pins than I expected.

What I would want to know is that the rfm69 needs a different pinout with this shield or not. I can't find any reference that tells me this, so I can start debugging the problem.

[cabat]

@sergio-rius sorry, my mistake, missed of using RFM69 in your setup..

[Sergio Rius]

@cabat Oh, no! Thanks for your help. It has inspired me. Now I'm trying something more.

[Sergio Rius]

I've been fiddling with the radio alone (serial gw), softspi and changing pins, and I think there's something else here.
Well those are my findings:

With this base definition and without the module wired:

#define MY_RADIO_RFM69
#define MY_RFM69_NEW_DRIVER
#define MY_IS_RFM69HW

#define MY_DEBUG_VERBOSE_RFM69

#define MY_GATEWAY_ENC28J60

It works as expected.

0 MCO:BGN:INIT GW,CP=RPNGA---,REL=255,VER=2.3.1
4 TSM:INIT
5 TSF:WUR:MS=0
6 RFM69:INIT
7 RFM69:INIT:PIN,CS=10,IQP=2,IQN=0
11 RFM69:PTX:LEVEL=5 dBm
13 TSM:INIT:TSP OK
15 TSM:INIT:GW MODE
16 TSM:READY:ID=0,PAR=0,DIS=0
19 MCO:REG:NOT NEEDED
72 GWT:TIN:IP=192.168.50.211
1075 MCO:BGN:STP
1077 MCO:BGN:INIT OK,TSP=1
1081 TSM:READY:NWD REQ
1083 RFM69:SWR:SEND,TO=255,SEQ=0,RETRY=0
1088 RFM69:CSMA:RSSI=-98
1090 TSF:MSG:SEND,0-0-255-255,s=255,c=3,t=20,pt=0,l=0,sg=0,ft=0,st=OK:

If I try to change CS pin to any other with #define MY_RFM69_CS_PIN 4 for example, I always get:

0 MCO:BGN:INIT GW,CP=RPNGA---,REL=255,VER=2.3.1
4 TSM:INIT
5 TSF:WUR:MS=0
6 RFM69:INIT
7 RFM69:INIT:PIN,CS=4,IQP=2,IQN=0
11 RFM69:PTX:LEVEL=5 dBm
13 TSM:INIT:TSP OK
14 TSM:INIT:GW MODE
16 TSM:READY:ID=0,PAR=0,DIS=0
19 MCO:REG:NOT NEEDED

So I revert the CS pin change and activate softspi and change irq #define MY_SOFTSPI and #define MY_RFM69_IRQ_PIN 3 And it works well:

0 MCO:BGN:INIT GW,CP=RPNGA---,REL=255,VER=2.3.1
4 TSM:INIT
5 TSF:WUR:MS=0
6 RFM69:INIT
7 RFM69:INIT:PIN,CS=10,IQP=3,IQN=1
11 RFM69:PTX:LEVEL=5 dBm
13 TSM:INIT:TSP OK
15 TSM:INIT:GW MODE
16 TSM:READY:ID=0,PAR=0,DIS=0
19 MCO:REG:NOT NEEDED
72 GWT:TIN:IP=192.168.50.211
1075 MCO:BGN:STP
1077 MCO:BGN:INIT OK,TSP=1
1079 TSM:READY:NWD REQ
1081 RFM69:SWR:SEND,TO=255,SEQ=0,RETRY=0
1086 RFM69:CSMA:RSSI=-98
1091 TSF:MSG:SEND,0-0-255-255,s=255,c=3,t=20,pt=0,l=0,sg=0,ft=0,st=OK:

Then I add the eth module and I get:

0 MCO:BGN:INIT GW,CP=RPNGA---,REL=255,VER=2.3.1
4 TSM:INIT
5 TSF:WUR:MS=0
6 RFM69:INIT
7 RFM69:INIT:PIN,CS=10,IQP=3,IQN=1
11 RFM69:PTX:LEVEL=5 dBm
13 TSM:INIT:TSP OK
15 TSM:INIT:GW MODE
16 TSM:READY:ID=0,PAR=0,DIS=0
19 MCO:REG:NOT NEEDED

And stays here forever.

Of course all those test are made using a double (5v+3v3) good power source, a level shifter... and changing the wires accordingly.

I have some questions:

• Its normal MY_RFM69_CS_PIN not having effect and breaking the radion connection?
  Without being able to change this, I don't know if it's spi interference.
• In the last test, it seems to halt when initialising the network. Doesn't it?
  Is there a way I can further know if the problem is with the eth module? I've tried it alone with the nano and it works.

I would thank guidance for debugging this.
