Setting EEPROM problem
PostPosted: Mon Apr 17, 2006 6:13 pm     Reply with quote
Hello,
i am using a pic16f914 and am setting values into eeprom thru view/eeprom then i set the values i want in the addresses needed. Upon powering up my circuit the values seem to be other than what i stored before compilation, however once i set the values in my project when PIC is running they are stored correctly and it works fine. I am storing the values of 00 from adress 00 to 0f. What could be causing the eeprom to store data other than the zeros i set there.

Thanks in advance!

Pedro

Code:

#FUSES NOWDT                    //No Watch Dog Timer
#FUSES INTRC                    //Internal RC Osc
#FUSES PUT                        //Power Up Timer
#FUSES NOPROTECT                //Code not protected from reading
#FUSES MCLR                     //Master Clear pin enabled
#FUSES NOCPD                    //No EE protection
#FUSES BROWNOUT                   //Brownout reset
#FUSES NOIESO                   //Internal External Switch Over mode disabled
#FUSES NOFCMEN                  //Fail-safe clock monitor disabled
#FUSES NODEBUG                  //No Debug mode for ICD
#use delay(clock=4000000)
#int_timer0


Code:

   timeron = read_eeprom(0x0a);//10
   closeonrelease = read_eeprom(0x0c);//12
   fastopen = read_eeprom(0x0d);//13
   fastclose = read_eeprom(0x0e);//14
   autospeed = read_eeprom(0x0f);//15

Normally, you initialize Data EEPROM with a #ROM statement.
Here's an example for the 16F-series PICs. Try this example:
