Thanks for the great response I've decided to use openlog from sparkfun with a micromite

There are cheaper ones to be found, I paid around �10 for one recently.

The code is open source, so it cant be difficult to build the processor etc onto a MicroMite board. A SD card interface would be better too.

$50SAT is Silent but probably still working.

Hi robert;

robert.rozee said the 32k(byte) I2C EEPROM devices out there seem like a far more practical choice in a micromite data logger - they are dirt cheap, and no more complicated to wire up than the RTC devices folks are currently using. the AT24C256 is one such device, available in a DIP package for a dollar or so on ebay.

and i seem to recall someone writing code to talk to these devices a while back, on the original MX150 micromite.

Try here .

Quote Today, it would perhaps be relatively simple to write some custom functions to do the job, treating the device as a simple series of pages. the datalogger application could then be responsible for managing how data is organized internally. similarly, the same application could be responsible for spooling saved data out to an attached console.cheers,
rob :-)

I have been working my way through twofinger's code which was specifically written for the Maximite v4.5.
And centrex's uMite version, also v4.5.
They were using 24C32 eeProms.
I'm trying to do this in v4.6B and using 24C256 eeProms.
The problem for me is the PEEK and POKE commands in the Floating Point commands which I can't seem to understand and gives me an error.

Yes, I understand the different page sizes and have made this work.
The '170 uMite has limited memory so, after I get the first 1/4th of the 24C256 working will add what might be called "Blocks". This way I can still use large eeProms and yet access all of them.

Anyway, what's withe

Thanks for the hint!

I will check this soon. But I can't imagine any reason for a different behavior (PEEK V4.5D vs 4.6B)

Edit:
UPDATE
This (quick & dirty) version should work with mmBasic 4.6 MK2 for AT24V32:

I hope I can also reenable the "monitor" function ... some day.Edited by twofingers 2015-03-27
