Iboard - Cheap Single board Ethernet Arduino with Radio

nneeoo

Hi. I just used MySensors library with the iBoard without any HW modifications. All You have to do is to edit utils/RF24_config.h.

uncomment the following line:

#define SOFTSPI   // Requires library from https://github.com/greiman/DigitalIO

and modify SOFT SPI PIN definitions to

const uint8_t SOFT_SPI_MISO_PIN = 6; 
const uint8_t SOFT_SPI_MOSI_PIN = 5; 
const uint8_t SOFT_SPI_SCK_PIN = 7;

And it all "just works" ;) Of course you have to have the DigitalIO library, too.

Nice one!

Hi. I have tried nneeoos' solution fot SOFTSPI, but the code only compiles if I use DigitalIO library in my main INO file too (I tried MQTTGateway ethernet on Iboard). I have the latest librarys. After uploading I get "check wires".

tbully

Hello. I too tried @nneeoo 's edits and am getting check wires.

Here's my relevant RH24_Config settings:

  const uint8_t SOFT_SPI_MISO_PIN = 6; 
  const uint8_t SOFT_SPI_MOSI_PIN = 5; 
  const uint8_t SOFT_SPI_SCK_PIN = 7;  
  const uint8_t SPI_MODE = 0;

And here's my setup in my gateway sketch:

 #include <Ethernet.h>   


 #define INCLUSION_MODE_TIME 1 // Number of minutes inclusion mode is enabled
 #define INCLUSION_MODE_PIN  3 // Digital pin used for inclusion mode button

 #define RADIO_CE_PIN        5  // radio chip enable
 #define RADIO_SPI_SS_PIN    6  // radio SPI serial select
 #define RADIO_ERROR_LED_PIN 10  // Error led pin
 #define RADIO_RX_LED_PIN    8  // Receive led pin
 #define RADIO_TX_LED_PIN    9  // the PCB, on board LED

 #define IP_PORT 5003        // The port you want to open 
 IPAddress myIp (192, 168, 34, 169);

To be clear, I'm not afraid to do the hardware modification but it appears that @nneeoo got it to work without doing so. If that's true, I'd like to go that route........

tbully

As an update....I gave up on the software method and just did the hardware modification.

All is well now.

One question: How did you guys do the LED and inclusion buttons? Did you carefully solder right to the Atmega chip or is there a better place to grab the needed pins?

What pins did you use for TX/RX/ERR/Inclusion?

gregl

Hi @tbully - i personally never bothered with leds/inclusion button.

My gatway is underneath my staircase near vera and my wifi router, so other than when i make a change, i never see it - so leds wouldnt help me.

When i do an inclusion i do so via software..so no button needed either...

I would like a nice 3d printed case for it one day...still havent boxed the iboard up!

Same here, @gregl . I appreciate your write-ups above. They really helped out. I'd like to find a printer and user @jtm312 's design but would like to know how he got the LEDs and Button wired up. Soldering directly to the chip could be difficult without a steady hand.

I am using the Itead iBoard as a gateway to a Vera Light for a few days now. Without any hardware modifications, only a few changes in header files required. I think the main issue is that you should map the inclusion button and led's to the Ax pins and use the full constructor (with 7 parameters). Beware of the last line in the first snippet. If you use the shortcut constructor (with three parameters), it will use defaults for the other parameters and your defs will be ignored.
To verify my assumptions above, I included a led to the A2 pin and it is blinking as expected on arrival of a packet.
The code below may look intimidating. But I posted the whole thing for easy reference. You can do the software changes in one minute.

Snippet from EthernetGateway.ino:

#define INCLUSION_MODE_TIME 1 // Number of minutes inclusion mode is enabled
#define INCLUSION_MODE_PIN  14 //A0 // Digital pin used for inclusion mode button

#define RADIO_CE_PIN        3 // radio chip enable
#define RADIO_SPI_SS_PIN    8  // radio SPI serial select
#define RADIO_ERROR_LED_PIN 15 //A1 // Error led pin
#define RADIO_RX_LED_PIN    16 //A2 // Receive led pin
#define RADIO_TX_LED_PIN    17 //A3 // the PCB, on board LED

#define IP_PORT 5003        // The port you want to open 
IPAddress myIp (192, 168, 178, 66);  // Configure your static ip-address here    COMPILE ERROR HERE? Use Arduino IDE 1.5.7 or later!

// 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.
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };  // DEAD BEEF FEED

// a R/W server on the port
EthernetServer server = EthernetServer(IP_PORT);

// No blink or button functionality. Use the vanilla constructor.
//MyGateway gw(RADIO_CE_PIN, RADIO_SPI_SS_PIN, INCLUSION_MODE_TIME);

// Uncomment this constructor if you have leds and include button attached to your gateway 
MyGateway gw(RADIO_CE_PIN, RADIO_SPI_SS_PIN, INCLUSION_MODE_TIME, INCLUSION_MODE_PIN, RADIO_RX_LED_PIN, RADIO_TX_LED_PIN, RADIO_ERROR_LED_PIN);

@hugob - Finally got to try this last night late...Success!

I did also need to add to the EthernetGateway.ino this line to load the Softspi libs...

#include <DigitalIO.h>     <-added this too!
#include <SPI.h>  
#include <MySensor.h>
#include <MyGateway.h>  
#include <stdarg.h>

I also needed to compile it under a newer IDE version due to memory..I used 1.6.5.

@gregl
Good to hear that you can confirm that this is working. My unmodified IBoard gateway is working for months now without problems. But as I said in some other topic, this board needs a decent power supply.
So all you need for a MySensors Ethernet gateway is this board, a NRF24L01 Radio that plugs in into this board, and a power supply. No mess with cables like in http://www.mysensors.org/build/ethernet_gateway. This board has 7 IO ports in case you want the leds. For $17.50 this is a no brainer.

hugob

OK, I did forget some minor drawback. You need a FTDI adapter to program this IBoard from the Arduino UI.

soward

I'm using this as a gateway w/ 1.5 also with no issue. I do have the LEDs hooked up as well, using an oversized 'recovered' power supply and the PA+LNA radio with no problems. All I need is a nice case...

My iboard gw is up and running so far so good!

Using the basic sketch with no LEDs

Question I see only A0 to A5 I/o s where or how can I use t he sketches pins d6 -d9 pins?

I printed the my sensors 3d stl file for the gw and it fits great, but there are the holes for the 3 LEDs and re include button .

Any help would be good maybe just a senior moment eh?

Print one

Switch today to MySensors 1.5 without any problem. Easy to setup softspi with MyConfig.h

Fabien

And test OTA with a sensebender, work fine ! :smiley:

@5546dug

In the original sketch, you map a variable to a Dn pin. E.g. INCLUSION_MODE_PIN is mapped to pin 3.
The iBoard has no digital ports (Dn) on a connector, but only analog ports (An). Luckily, the analog ports can also be used as digital ports. The modified sketch maps the variables that were mapped to a Dn port in the oririginal sketch, to an An port in the modified sketch. This is the list:

Original
INCLUSION_MODE_PIN 3 // Digital pin used for inclusion mode button
RADIO_ERROR_LED_PIN 7 // Error led pin
RADIO_RX_LED_PIN 8 // Receive led pin
RADIO_TX_LED_PIN 9 // the PCB, on board LED

Modified
INCLUSION_MODE_PIN 14 // A0 Digital pin used for inclusion mode button
RADIO_ERROR_LED_PIN 15 // A1 Error led pin
RADIO_RX_LED_PIN 16 // A2 Receive led pin
RADIO_TX_LED_PIN 17 // A3 the PCB, on board LED

So for the iBoard, the receive LED has to be connected to pin 16 (A2). Etc.

If you carefully look at the code, you will notice that also RADIO_SPI_SS_PIN changed from 6 to 8. That is because the header for the radio chip on the iBoard is connected to a different Arduino pin on the iBoard, than it is on the wiring diagram of the original gateway diagram. But this is just an internal issue. It should not bother you if you build the gateway.

@hugob Thanks

Hi Guys!
I have got a Wborad Ex board with built in wifi (rak410) from itead.
http://wiki.iteadstudio.com/Wboard_Ex

Unfortunately I can not find anywhere arduino code that would work of the board with wifi.
Does anyone have the same board and could possibly help?

Itead said it works on this demo, but without success .
