Hi there

I've got a data memory address ans i want to access to it's content. I this is in the L36SARAM of my picollo.

It is possible to copy it to a variable used by me?

I tried to point to the memory address and i couldn't copy it.

It is something like this:

unsigned long int teste_dat[10];

test_data[0]=*(data_memory [address]);

please help

Best regards

Hi Manoj Santha Mohan

Thank you very much for you reply.

I've already accessed to this data positions.

Now i want to change the data from a determined Data memory position. I want to copy data into a determined position.

Like:

Data memory Adress.Value == Array[10];

Please help

best regards

Please check now.

#define START_ADDR (Uint16*) 0x9000 //Starting address of L3SARAM
#define L3_LENGTH 0x1000                   //Length of L3SARAM
#define DESTINATION_ADDR (Uint16*) 0xA000 //Destination address of L3SARAM

main()
{
Uint16 *Addr,*Dest_Addr;

Addr = START_ADDR;
Dest_Addr= DESTINATION_ADDR;

while((Uint16)Addr<=(Uint16)START_ADDR + (Uint16)L3_LENGTH -1))
{
        *Dest_Addr = *Addr;
          Dest_Addr++;
}
}
