Please, help me ?
I have a problem when I try to write the memory eeprom. My memory is durty when 2 sensors is on.

#include <16f877.h>
#fuses HS,NOWDT,PUT
#use delay(clock=4000000)

| What memory? You didn't include the eeprom driver? |

No you don't need a memory driver. The function you called is built in.
Do you know what a for loop is? CCS places the write_eeprom() inline. You whole zero memory function is way too complicated versus what it needs to be.
| Code: |
for(i=0x21;i<=0x60;i++)
write_eeprom(i,0);
|
Now in the above code, I am assuming that you made an error in that 0x30 does not come after 0x29. It should be 0x29,0x2A,0x2B....0x2F,0x30. |
