Hi
I have a logger project with 16f877 and it is logger project whit large volume of data!
I need connect a mass storage to save my data on it! i think it is perfect way for me!
Best Regard
Is this a question or statement of fact? There are no question marks in your post
Assuming it's a question perhaps you could tell us how much data is a "large volume" in your application; Kbytes, Megabytes, Gigabytes ?
How often is it being updated and what do you need to do with the data once it's logged?
You could use
- A compact flash card
- An MMC/SD card
- A USB Memory Stick
And the winner is... The SD Card! Simple to interface to a PIC. LOTS of storage space for dirt cheap.You could use

I have a similar problem. My understanding is that it's moderately straightforward to dump data onto an SD card but not in a format that can be read by a computer (i.e FAT).
If that's the case then EEPROM ICs would be just as useful (GBytes of space aren't required.) Microchip sell them up to 1Mbit in SPI and I2C types. I was going to use such an EEPROM IC, and when I wanted to access the data simply take it out of the circuit and read its contents into the computer using the PICKIT2 software.
Is this madness?
Since I just did a USB device it is no longer difficult or even particularly mysterious. I see no reason why it can't be done. Most of what you need is readily available.Not number 3, it's a really poor choice as it's very difficult to use.

NYC is very expensive.
