read write program memory PIC24
PostPosted: Fri Sep 21, 2012 7:14 am     Reply with quote

Hi everybody,
I feel so stupid because i can't write and read a simple variable in my PIC24HJ.
I notice that no EEPROM figure out but i can write in a flash memory.

Code:

#define ROMCALOC 0x4000
#org ROMCALOC,0x4002 {}



in to the main
Code:

int32   addr;
int8 data[2];
int8 data_r[2];

write_program_memory(addr,data,2);                     read_program_memory(addr,data_r,2);


why it does not work??
Thanks in advance.

Firstly thanks for all answers.
I understood how flash works and here is the solution.
Code:

#define CK_FLASH_END       (getenv("PROGRAM_MEMORY")-1)     
#define CK_FLASH_PAGE_SIZE (getenv("FLASH_ERASE_SIZE")/2)
#define CK_NUM_PAGES (CK_FLASH_END/CK_FLASH_PAGE_SIZE)

#define CK_USER_PAGE (CK_FLASH_PAGE_SIZE*(CK_NUM_PAGES-1))

#org CK_USER_PAGE,CK_FLASH_END {}



in main code:
Code:

unsigned int8 read_data[8];
unsigned int8 write_data[] = {12,34,56,0,25,42,1,0};

write_program_memory(CK_USER_PAGE,write_data,8);
delay_ms(1);             
read_program_memory(CK_USER_PAGE,read_data,8);


P.S:CCS 4.134
