Gateway Uno R3 + W5100 Ethernet Shield for Uno not working.

[mfalkvidd]

Also, are you sure the w5100 shield you are using is capable of managing the SPI_EN signal?

[pw44]

these are the real photos of the setup.

wire codes are the same as the build instructions ;-)

managing the SPI_EN signal? tried with and without, no changes.

@pw44 you seem to have the same w5100 shield as i have. Try removing the sd card.
If that doesn't work, try my fix here : https://forum.mysensors.org/topic/9732/arduino-uno-with-ethernet-shield-w5100-not-working/10

@Yveaux
Thanks for the reply, removing the sd card or applying your fix did not change the problem.

@pw44 why are spi clk/miso/mosi connected to A0.. 2 ¿

Yes, but the sketch just below it has

//#define MY_W5100_SPI_EN 4

You actually have enabled this line, which causes the arduino to use hardware spi. And hardware spi uses different pins for clk/miso/mosi.
You wired for software spi, so comment that line as in the example.

@Yveaux

thanks man, you're right. commenting out

//#define MY_W5100_SPI_EN 4

solved it.

now, debug shows:

just another question: does the 3.3v line from Uno R# enough power to handle the RF24 radio?

Thx in advance!

[pw44]

@Yveaux and regardin IRQ from RF24, is it necessary to connect to pin2 of UNO R3?

[mfalkvidd]

@pw44 no

The IRQ pin is only required to be connected if the MY_RX_MESSAGE_BUFFER_FEATURE is defined in the sketch. Using this feature is recommended for high traffic nodes or gateways. Enabling it will result in better throughput but will require some additional memory to keep the message in memory before processing.

More information: https://www.mysensors.org/build/connect_radio and MY_RX_MESSAGE_BUFFER_FEATURE

[pw44]

@mfalkvidd
thank for the answer.

i guess the UNO R3 is capable to do it, so, i tried

#define MY_RX_MESSAGE_BUFFER_FEATURE
#define MY_RF24_IRQ_PIN 3

and got the following error:

#error RF24 IRQ usage cannot be used with Soft SPI

Any hint? The idea is having something like 80 nodes when all is done.

Thx

[mfalkvidd]

@pw44 unless your nodes send very frequently, you probably don’t need irq.

If you need irq, you’ll need to use hardware spi.

Ok, but just in case, how to use the hardware spi in this configurartion (sorry if it seams stupid, but i'm just a very beginner on this).

Thx for the understanding and also for educating me,.

[mfalkvidd]

@pw44 I don’t think anyone has managed to make the w5100 work on the same spi as nrf24.

[pw44]

@mfalkvidd

ok, i was curious as i didn't find how to.

Anyway, is it possible to have the "RF24 IRQ" used as soft?

[Yveaux]

@pw44 no, mysensors doesn't need it for soft spi and won't use it
