Emulating an SDcard

[Mosaic]

Hi:

I have an ID tag application to develop with about 1 Kb of fixed text to PCs.
Is it to use a PIC to deliver this data via an SD card interface?

In effect creating a 1kb read only SD card function. I prefer not to use a gen. purp. SDcard.

Perhaps the PIC could read the data from it's code space.

The SD card protocol is fully documented, what you want to do can be done simply by reversing the protocol.

Thx Scaed:

Was kinda hoping someone had done it and could help out....

Mebbe some asm sample code would be a good start!!

Down load this file there a data loger in there that uses SD have a look SD.inc Just reveres protocol reciving data to waiting to send data .

It should help you https://www.gedanken.org.uk/electronics/amb-pic-code/amb-pic-code-2010-09-19.tar.gz
