atmega sd card
hi everybody,
I have managed to impliment FATfs module on ATmega128,and it's very well able to communicate(for reading and writing) with card through serial interface..but for ATmega 32,i am facing a lot of problems..like..
1.the microcontroller is not detecting the card that i have interfaced through SPI to it.wat may i do, i get the same output when i try initialising the card,even if the card is connected or not ,i get the same output...
my concern is...is there a way i can check whether there is a problem with the hardware(the socket that i have used in connecting card to the microcontroller)or with the software(changes that i have made to the SPI interface in program for ATmega 32 )...
i hope i am clear enough with the problem that i am facing...
god bless
