MMC

hey all im trying out a new project to store data onto a multimedia card. As far as i know i need this in fat format so that i can open up a text document in windows.
Im really struggling with this.
Has anyone done a simillar project just so i can get an idea, or are there any sites out there which would be of use.

Thanks.

can anyone help me out?

help!!!ADC 8535

hi im in desperate need of some help. using the stk500 and an 8535 chip.

All i'm trying to do is to read a voltage from portA, (which i think is the default for analog input) and output that value through a serial interface. I used the code wizard and this is what i got.

// Read the AD conversion result
unsigned int read_adc(unsigned char adc_input)
{
ADMUX=adc_input;

// Start the AD conversion
ADCSR|=0x40;

// Wait for the AD conversion to complete
while ((ADCSR & 0x10)==0);
ADCSR|=0x10;
return ADCW;
}

to access this function in my code.
i use:

rawdata=read_adc(0);

which as far as my knowledge goes will get the value of the reading at pin.0 and store the value in rawdata.
It does not work, i don't get the value of the voltage, i get 0 when a voltage is connected and 15 when it isn't connected.

Can anyone please hekp?? Do i need to connect something? do i need more code? Any initialisation?
