It is hard to develop under limited eeprom, because you build document of LCOD is also limited, so I change the rom to SD card, that is very easy and fast. Now it is enough for development of middelware, because it is usually 16GB or up. I use arduino’s libs and hardware to applicate, and be feeling relax to implement.
First the procedure you must check the exists of file you want to access. If it is none, please touch 1MB up of zero data of file, then file open that. so when iLogic_write_eeprom_byte or iLogic_read_eeprom_byte event, please before accessing date you need to seek the file director. and read/wirte the binary data you can assign/read. Of course that procedure is for one byte, so I add iLogic_write_eeprom_pbyte / iLogic_read_eeprom_pbyte to read buffers and assign binary data from buffers. It shall accelerate the prcedure. Now I can build huge document of LCOD and find subjects to text books.
I hope I write this is useful who want to develop in arduino due. And that is easy way and tell how to do will be great !!.
