my program will assemble but wont output anything onto pickit3 with pic18f45k20

[marsal]

my project is to find the average min and max of a list of several values and then convert it into bcd and display it on the LED of the pickit3, it will build and debug on the simulator however when i connect it to the pickit i receive no output please help here is my code:

list p=18f45k20
   #include p18f45k20.inc

[dannyf]

to find the average min and max

What is "average min" and "average max"?

[marsal]

average of the values, the min is the lowest value from the list and the max is the highest value of the list

[dannyf]

Save yourself the pain and suffering and learn C.

[jucole]

Hi,  where are your config settings?   why did you chose to write it in assembler?

[David_AVD]

Have you tried some simple blinking LED code to make sure the config is correct and the hardware is good?

[marsal]

i would use c but assembly lang was a requirement for this project

my congif settings are:
;//** C O N F I G U R A T I O N B I T S ***********/
 CONFIG FOSC = INTIO67    ; INTIO67 Note that if it is HS it will not work!
 CONFIG   LVP = OFF
 CONFIG   PWRT = ON

 CONFIG FCMEN = OFF
 CONFIG IESO = OFF ;// CONFIG1H

 CONFIG BOREN = SBORDIS
 CONFIG BORV = 30 ;// CONFIG2L
 CONFIG WDTEN = OFF
 CONFIG WDTPS = 32768 ;// CONFIG2H
 CONFIG MCLRE = OFF
 CONFIG LPT1OSC = OFF
 CONFIG PBADEN = ON
 CONFIG CCP2MX = PORTC ;// CONFIG3H
 CONFIG STVREN = ON
;
 CONFIG XINST = OFF ;// CONFIG4L
 CONFIG CP0 = OFF

 CONFIG CPB = OFF
 CONFIG CPD = OFF ;// CONFIG5H
 CONFIG WRT0 = OFF

No RETURN in Blinking?

[JTR]

As above Plus

Since when has the reset vector for a PIC18F45K20 been at 0x20?

LOOP:   TBLRD*+
        MOVFF   TABLAT, WREG
        MOVWF   POSTINC0
        CPFSEQ  0XFF           <- Are you kidding? Read the data sheet.

[marsal]

The last value will be 0xFF, indicating the end of the data (0xFF is not counted in the summation calculation).

[JTR]

        CPFSEQ  0XFF

Please, please, please... READ THE DATA SHEET!

[westfw]

CPFSEQ compares W against a file register's contents, not against a constant.
