Looking a whole lot tidier than my usual efforts.
I decided to use the Breadboard icon & assemble everything on there - so it's very much a WYSIWYG diagram; just wire up a breadboard as in the diagram (i've got one of those big ones with the side rails - had it it for 30 years or more, & i thought i'd lost it (whew!!)).
No imagination or interpretation needed; i even colour-coded the wiring to match the stuff i got in my MindKit starter pack (lots of Orange leads for some reason..). Given that it's Stupid O'clock in the morning right now, the less thinking i have to do the better!
I'll post some Serial Monitor output later - i'd like to experiment with variations on the basic design so as to illustrate the actual 2-wire goings-on,
like requesting half a message,
or a specified part of it,
or varying start-addresses, message-length & the like
Once i get that sussed, Data-logging should be a treat!
(Regretably, that never happened. And i had to 'debug' the breadboard as well)
..& that'll do me for now.
ReplyDeleteSpectacular stuff on the Iceland-the-Volcano last night on Prime!
The whole of Iceland IS just one big concatenation of volcanic outlets (like Hawaii, only worse/more so, depends on how you see it), & some of them are Really Big Mean Mothers; kinda like the Northern Lights with attitude!!
Arrrgh!
ReplyDeleteNow that i look @ MY large breadboard, i see it has only two rails, not four!
Just makes life a little more annoying..
And this breadboard has two errors.
ReplyDelete(1) the original diagram specified pin 12
as the push-button pin - i've used pin 13
(2) two external EEPROMs are shown, but they are connected so that their addresses are identical.
Potential for conflict when being read.
