I dont own a PICDEM2 PLUS BOARD but im sure you should be able to since its a DEM boards.
about the schematic ... not really needed but always good pratice... the issue is you need to learn how the software works to effectively setup the hardware.
If you setup the hardware without know what the software will do then its useless because you might be miss wiring.
What i recommend is you Learn SPI (or the bit-banged version) this way you know how to wire the Maxim chip when you get it.
Please download the Datasheet for that chip asap and study it. To learn how it it works with the pic read carefully:
PAGE 7 & 8 :
Detailed Description, Initial Power-Up and Operation, 4-Wire Serial Interface
This will tell you everything you need to know on the communication side. The only wierd part here is that it isnt a normal SPI its a 4 Wire which is like its own type. (Well at least in my own opinion)
The CS line would be the LE but its not really a CHIP SELECT line here its a sort of toggle-enable line. Where as after you send your data you set it high and then low. After you set it low it will set the new data latches from the internal shift register.
Its really easy when you read it. I dont know how to explain well
but when you read it you will see what i mean.
I dont think you will use the OE line. Read this from datasheet:
The fourth input provides output-enable control of the
output drivers. OE is high to force outputs
OUT0–OUT15 high impedance, without altering the
contents of the output latches, and low to enable outputs
OUT0–OUT15 to follow the state of the output
latches.
Which is basically a floating pin. (
Hi-Z = High impedance)
The others should be direct enough to know.
