Access to program memory

[Akutabi]

Hi,

I'm trying CCS compiler and wished to access a char array stored in program memory. To do it, I first tought I could use a pointer but CCS doesn't allow pointers to constant datas.

So I tried to retrieve the address of my first element in the char array to use the function read_program_memory but it didn't work either, so is there a way to access it without using an index to the array ?

Thank you,

Here is the idea I tought could work :

const char msg[] = "Hello World!";
int16 addr;
char *data;

//Retrieve the address in program memory of the first element
addr = &msg[0];

//Read program memory and store it in RAM
do
{
read_program_memory(addr, data, 1);
addr++;
}while(data != NULL);

Look at the asm code generated when accessing a const array. You will see why the read program memory doesn't work.
