Saving arrays to 24c256 ????

[mindstorm88]

Hi guys , i want to use Roman Black 1 bit BTC to play some speech !! i tried it and it does the job i need perfectely, But it needs lot of memory !!

So for now i have few arrays of 255 bytes to replay 1 word, i need more memory than the controller capacity !!!

How can i save all these array to external memory when programming???

Thanks

You need to buy or build an eeprom programmer. Google this:

I have the picdem plus, but i have never tried to trasfer file via rs-232 , i guess i'll have to find example !!!!!

Thanks

His suggestion is the easiest way. If you want to go all out you could write some sort of transfer protocol. When I was messing around with graphic LCD's I wrote a basic XMODEM implementation that would allow me to upload a file to the PIC then it would write it to an external 1Mbit EEPROM. Probably more complex than what you want, but it was nice since I could just upload new images without changing anything (board was always hooked up via RS232).

I would, probably, do like amcfall suggested. I have most, if not all, of the components available to make a small board with a zif attached. Just write a small program to accept data, via RS232, and write that data to the eeprom setting on the board.

One draw back is that you now have one board that is dedicated to one function. Whereas, if you purchased a eeprom burner then you could use it to program a variety of things.

You'll need to weigh the cost/rewards/use thing to decide which way you wanted to go.
