Thread: Data Logging using a 16F877
face picon face BY : Olin Lathrop email (remove spam text)

I'm trying to use a PIC16F877 to log data taken from the A/D converter. (I
will need to store in the region of 24000 16-bit numbers). I already use
EEPROM memory on the chip is there other data memory that I can write the
measured data to so that I can read it off at a later point?
Or do I have to look for extended memory? If so how is this accessed?

There is noplace on a 16F877 to store 48Kbytes of data.  You will have to
use an external memory.  Depending on the speed you need, an IIC EEPROM
might be a good fit.
