S12zvl EEPROM number of bytes read

[charudattaingal]

bool Read_Data(unsigned char *buffer, unsigned int long  eeprom_address, unsigned char size)

{

   unsigned char i;

    while(FSTAT_CCIF == 0);   //wait if command in progress

    for(i=0;i<size;i++)

    {

        *(buffer + i) = *(unsigned int * ) eeprom_address;

         eeprom_address = (eeprom_address + 1);

    }

} /* Read_Data */

while calling this function it is not updating  the first byte read  in buffer and but other data is available.

Eg;

unsigned char  data[10];

unsigned char *buffer=data;

unsigned int arr[]={0X11AA,0X2222,0X3333,0X4444,0X5555};

this i wrote on EEPROM on address  0x100000  to  0x100009

so in data there is no first byte available

it is data[]={0XAA,0X22,0X22,0X33,0X33,0X44,0X44,0X55,0X55};

Hi,

“on address 0x100000  to  0x100009”

“data[]={0XAA,0X22,0X22,0X33,0X33,0X44,0X44,0X55,0X55};”

I see just nine numbers. Data should contain also value from address 0x100009?

You combined data types – you wrote int into char.

Could you please use

*(buffer + i) = *(unsigned char * ) eeprom_address;

Instead of

*(buffer + i) = *(unsigned int * ) eeprom_address;

I hope it helps you.

Have a great day,
RadekS
