Hi Guys
Do you have any tips on implementing Caller ID?

There's a few features I feel are missing from current CID units which I
personally want to build. Also my NZCE Electronics (polytech) course
requires a project soon, so I thought I'd kill two birds with one stone. Who
knows, someone else may need one too.

Questions:
- What are the code requirements to I/F to a CID chip?
I don't know what protocol the CID-chip spits the data out in,
is it relatively simple serial-type data, or real messy to bit-bang?

- Is the CID format [date,time,number...] standard, or could the US standard
I've read a few things on be different than implemented here in New Zealand?

Also..
- Lcd display (I saw a PICListers website do this serially)
- I'll need to store number/name... data - i2c eeprom?
- Audio caller announcement (I have ISD1020 ChipCorder).

- What should I be aware of when interfacing several devices...
ie. parallel data & address decoding vs. several SIPO shift reg's,
timing and co-ordination seems a not too tall order here on the surface
(famous last words :) etc... (Oh, & will this fit in an 'F84?)

Thanks in advance for any help/advice/suggestions,
David Vandenberg
