Writing on SD memory with fat32 format with ATXMEG
no vote
Hello everyone,
This program is designed for atxmega128a4 microcontroller in order to write on a SD memory via fat32 format in Codevision IDE. It uses SPI protocol on port D to talk to memory. Also note that in order to use "ff.h" library, you must first go to "Configure Project->C compiler->libraries->MMC/SD/SD HC Card".You should both tick the "Enable..." and "SPI slow clock" options. also you must connect the CD and WP pins to ground. Remember to use 3.3v on power for memory. If using 5v microcontrollers, you must use a level coverter from 5v to 3.3v, otherwise it won't work.
