problem to retrieve a image store in program memory
PostPosted: Wed Jan 21, 2009 2:14 am     Reply with quote
Compiler PCH v4.039 PIC18F66J60.
I store a large image which is defined
Code:
const char Imag[] = {0x00,0x01, ........};

about 2000 element.
Code below can retrieve data in image correctly
Code:
memcpy(cData, Imag, wLen);


Since I need to access the image not just from the beginning
but code below cannot retrieve data in image correctly even if the addr is 0.
Code:
memcpy(cData, Imag + addr, wLen);

How can I access the data image ? Thanks in advance.

problem are solve by using following codes to retrieve data from image.
code:
for (i = 0; i < wLen; i++)
{
*cData = Imag[addr];
addr++;
cData++;
}
