EtherTen Pin Reference

The EtherTen combines an Uno-equivalent Arduino-compatible board and Wiznet-based Ethernet support, along with a microSD card slot and Power-over-Ethernet support. [Product page]

EtherTen Pin Reference

Post by triaco » Tue Feb 04, 2014 5:45 am

I've made this EtherTen Pin Reference for myself.
And I would like to share it with other beginners who are struggling.

Well done and thank you for sharing :)
Don't forget A6 and A7 are broken out below the MCU.

Thank you for telling me.
I had no idea about this hidden treasure.
It's good to have 2 extra inputs, just what I need it ( 1 for LDR and 2nd for LM335 )

I have already UPDATED all files.

Would you tell me why A6/A7 have NO terminals ?
I know they can't be used for outputs, and they haven't any pull-up resistors. Otherwise they fully working PINS.

There isn't a standard position for those pins so we leave it up to the user to decide how they want to connect to them.

johnb,
What's about A6 ?
I am reading that the RESET input is multiplexed with that PIN,
and is determined by the setting RSTDISBL.
Can you translate it into plain English ?
Where's it , in a bootloader ?
Are there any precaution related to that pin if it is used as Analog IN.
I am asking because I'm planning to use that PIN.

A6 isn't multiplexed with anything, (nor A7 for that matter).
Please review the schematic - page two, top of coordinate area D8 -

I've seen this schematic before.
I was thinking that is multiplexed internally, inside ATmega328.

So there are none precautions,, I can use it safely ?
I am repeating the last question 'cos when I was updating this post you were faster then me in reply.

If you're using Arduino IDE and code, then they behave as A6 and A7. So for normal Arduino use, they're just two more ADC pins.

If you're programming in straight C/AVRstudio etc. and manually change the fuses those pins do have alternate functions. See page 14.3.2 of the full ATmega328 data sheet.

Thank you very much for clearing my mind.
I was very confused after reading the book below:

http://books.google.com.au/books?id=U6E ... CDgQ6AEwBA

I enioy Arduino IDE, simple but does job very well. I guess AVR Studio is not for me.
But once I get familiar with Arduino platform I'm going make a switch to Apple's Xcode (embedXcode).

And by the way I might not use those pins at all.
This morning I swapped the EtherTen for EtherMega at Jaycar, and bought one of your LCD modules.
I still got one EtherTen, and intend to keep it as a playground.

It feels like Christmas all over again...I had no idea these two little gems existed.

They have just made the following question less important but I still need to ask just in case. Are A4 and A5 still available as inputs when using an I2C device connected to the SDA/SCL pins next to AREF? If not, is there any way to share these pins with say a light sensor module and a 12v battery voltage monitor (via voltage divider) respectively?

I am putting together an analogue hungry project so a couple of extra pins would come in handy.
