external eeprom?

[reaperarch]

hi all,
i would just like to know if it's possible to interface an external eeprom chip to a
picaxe 08m.
i was thinking shiftout/in but i read somewhere that you have to use pulsout to send data manually. is this true for m series? can you make a datalogger out of a 08m?
thanks.

You can. You need to use a technique called 'bit-banging' which means your program has to control all I/O line interactions, and that uses up some code space for your main application, but there should be enough space for a datalogging program. You can use SPI or I2C Eeprom. There should be example code for both on this forum and on other user's web sites and people here who can help with problems you may run into.
