Hi,

I'm trying to connect a W5500 ethernet module to the sensebender gateway, to that end I'm trying to decipher how the pins on the SAMD are mapped to pin numbers and I'm getting a little confused.

Looking in the W5100.h file library within the samd/1.05/libraries/ethernet I can see ETHERNET_SHIELD_SPI_CS is mapped to pin 24 (PB11), which on the sensebender schematic is labelled NET_RST and not NET_SS which is pin 28.

The variants.h file for this micro doesn't appear to throw any light on the subject, as the defines for the W5100 maps PIN_SPI1_MISO to pin 22, this physical pin is GND in the schematic.

Any help most appreciated, or a link to a tutorial would be cool :)

Thanks,

Glen.

@m26872. Thanks for the design, very nice.

On your posted picture of the GY-21, why have you added extra resistors? The Gy-21 has it's own pull ups 4.7k for the i2c bus, so additional resistors are not required!

I removed the voltage regulator from the gy-21 board as well (detailed elsewhere in the forum) to save a little extra power. The only caveat to this is you've got to remember to remove the radio and gy-21 when programming using the usbtinyisp or usbasp as they run at 5v which could damage them.

I'm using the (hallard) breakout board for the rfm69cw which has a much better range than the nrf24's (no idea why people use these unless they live in a rabbit hutch)

Anyway, thanks once again for sharing.

Glen.

I found the information on the site below to be very useful in creating sketches for monitoring power usage of both the house and individual sockets
