UNI/O driver?

Rayman · 2014-11-06 09:06

Anybody have or seen a UNI/O driver for Propeller?

This seems to be a new 1-wire like protocol that Microchip now has for EEPROMs.

I'm trying to hack my Da Vinci 3D printer's filament cartridge... Turns out all I have to do is reprogram that EEPROM.
Then, I can load it up with Makerbot filament (that I have a lot of...).

I could convert Arduino code, if a driver doesn't already exist...

The Microchip device in Da Vinci is the 11LC010

I hadn't heard of that driver until now -- will order a breadboard-friendly TO-92 EE from Digikey to give it a try. Shouldn't be very difficult to write a PASM driver for that buss (I know you'll beat me to it, so let's compare notes later).

I'm actually pretty busy and this isn't urgent, so I'm more than happy to wait

Don't think assembly speed is required since only writing a few bytes and just one time...

TO-92 is interesting! Don't think I've ever seen eeprom like that before...

Actually, I suppose these tiny things do save a lot of board space and one I/O pin...

Doesn't need pullup resistors either.

A long time ago one used to be able to get Dallas 1-Wire EEPROMs, but these look easier to use. I'll try it in Spin, first, and then give a PASM driver a try.

Hello All,

Dragging this post up from the past.....did any of you write up a driver for the UNI/O?

unio is pretty simple to implement.. to bad largest unio eeprom is only 2K byte

*bump* wondering whether anyone got uni/o working? @rayman @jonnymac ?

If not I'll have a go at something basic today with P2

I have not. Distractions. Distractions. Distractions.

UNI/O driver?
