Getting started with UNI/O

Projects Networking, Protocols, and Devices

Hello guys,

I got a SOT23-3 EEPROM, it has a single wired communication protocol.
Precisely, it's a UNI/O protocol.
This memory recquires a command line for read/write as usual, and returns a Acknowledge in the end.
I would like to test commands to see wich responds and keep them for further investigation.

But not really sure how to send bytes via UNI/O. Like, is OneWire library enough for it or does it recquire "resets"?
Also, using Logic software I couldn't find UNI/O protocol, so again... using 1 - Wire works in this case?

(Using Arduino UNO)

It helped me a lot, thanks!

I started trying to implement a bit-bang to understand it better.
But got stuck to receive bits.
How could I bit-bang reception of data?..

@ito268 and @2112 Using the UNIOshell I am able to read and write the EEPROM values. But I need to parallelly read and write with 8 EEEPROM in different digital pins 2,3,4,5,6,7,8,9 . have you guys done this before?

Never done parallel functions before.
I'm not sure how the UNIOshell works. With the implementation I'm working, it is possible to define which pin will send/receive.
Manipulating "manually" you might get it working with multiple EEPROMs.
Could you share how you managed to use the UNIOshell?
We can help each other if you want!
