Subject: EEPROM on the 16f684

Hi,

 

I am writing to the EEPROM on the PIC using the programmer, and it reads
it back so its going in ok.. but for the life of me I can not get the
code to read it back out again. I have tried several examples online and
I keep getting odd characters back ([1]is the character, 20h) whatever I
put in. I am sending it as serial to hyperterminal but I know that to be
good transmission code as I send other characters. Here is the current
of the many attempts at reading it

 

 

eeread macro addr,prom

            movlw addr

            movwf EEADR

            call E2read

            movwf prom

            endm

 

E2read

            bsf STATUS,RP0

            bsf EECON1,RD

            bcf STATUS,RP0

            movf EEDATA,W

            return

 

            eeread 01h,SendByte

 

If anyone could spot any problems with this I would be very grateful.
Thanks in advance for any help.

 

 

Steve
