Hello sir, I am using pic16f873a eeprom to store value. In ccs compiler I write program like this
| Code: |
ROM 0x2100={35,27}
hc=read_eeprom(0);
lc=read_eeprom(1);
to read eeprom
write_eeprom(0,hc);
write_eeprom(1,lc);
to write eeprom
|
When i complete one cycle of this operation, i am not able to read the lc value, but no problem eith reading of hc.
Can anybody point out what is the problem with this program. Thanks in advance. |

Since you don't post a program, not much we can say!.....
However:
| Code: |
#include <16F873A.h>
#FUSES NOWDT,HS,NOBROWNOUT,PUT,NOLVP
#use delay(clock=20000000)
#use RS232 (UART1,BAUD=9600,ERRORS)
#ROM 0x2100={35,27}
void main() {
int8 hc,lc;
hc=read_eeprom(0);
lc=read_eeprom(1);
printf("hc= %3d lc=%3d\n\r",hc,lc);
do {
}
while (TRUE);
}
|
Happily displays:
You need to look at details. For instance, the ROM statement, is #ROM, not ROM as you post. Remember also, (you don't show how you are using them), what might have changed variables, so they don't do what you expect.
Best Wishes |
