I need to log data and retrieve it via RS232 port to a PC to analize.
Can you guys give me some pointers as I havent done something like this
before. What's the best option to go about to interface to some external
memory.

Best regards

It all depends how much data you need to store. 16 kB or less, use an
I2C or SPI EEPROM from uchip or xicor. Up to 512 kB use a NS  NM29A040
with microwire and above that a NAND flash f.ex NM29N16 with a byte
serial i/f.
A 16C63 will be a perfect choice. NS has several  appnotes how to use
and interface these chips theat you could get from http://www.ns.com

Hello Jattie,
I' m working on a datalogger for measuring temperature and humidity
using a PIC16C84. The data is stored in IIC- EEProms 24LC65 from Microchip. You can use up to eight 24LC65 (64KBytes of data) on one IIC-bus driven with 2 I/O-lines. If you need more memory its possible to drive more IIC-buses, since the bus is realised in software (Microchip AN558).
