hi,
i'm working in a project in which I'm exploiting IC of s1mp3 mp3 player, this kinfd of mp3 players has a SoC (System On Chip) called ATJ2085 which manage a NAND flash memory (a SAMSUNG k9f2G08U0M, it's not SD or MMC) through parallel links and use the FAT16 as a file system for it. in this project I have to share this memory with the PIC (18F4525) to write, read and display with an LCD -connected to the PIC-the content of the flash memory (songs, texts,etc....), and here I get a big problem cause all application notes and C programms for PIC that I did found in internet were made for SD, MMC cards or CF (Compact Flash) who communicate with the memory for R/W through the SPI bus !!!!
I'll be very grateful to anybody who will give me eany kind of advice, cause I'm turning around for days now without finding any solution.
