Confused On Dig & Lookup

[SOMRU]

Greetings !! As Usual I'm In Search Of Answers,
We're Using A Pic16f870 Using The Following Code:

DEFINE OSC 20 'DEFINE OSCILLATOR
DEFINE SER2_BITS 8

AS VAR BYTE 'DEFINE VARIABLES
D VAR BYTE
F VAR BYTE
N VAR BYTE
S VAR BYTE
T VAR BYTE
I VAR BYTE
A VAR BYTE
B VAR BYTE
K VAR BYTE
E VAR BYTE

'EQUATES SECTION
TRISA = %00111110 'SET PORTS I/O
TRISB = %00000000
TRISC = %00000000
ADCON0 = %00000000
ADCON1 = %00000011 'PORTA ALL DIGITAL

A = 123 'INITIATE VARIABLES
AS = 0 'FOR TEST RUN
D = 0
F = 200
N = 0
T = 1234
S = 0
A = 0
B = 0
I = 0
K = 0


'IT ALL STARTS HERE

PAUSE F

LOOP: 'GET T&C FROM PIC7

'IF PORTA.4 = 1 THEN
'SERIN2 PORTA.0 \ PORTA.1, 396, [T, A]
AS = A * 10
ENDIF

LOOP1: '8 DIGITS TO DISPLAY T & A

FOR E = 0 TO 3
PAUSE F 'DISPLAY T =1234
LOOKUP T DIG E,[$41,$F3,$49,$61,$33,$25,$05,$F1,$01,$31], PORTB
LOOKUP E,[$EF,$DF,$BF,$7F],PORTC 'SET DIGIT
PAUSE F
PORTC = $FF
NEXT E

FOR B = 0 TO 3
PAUSE F 'DISPLAY A =5678
LOOKUP AS DIG B,[$41,$F3,$49,$61,$33,$25,$05,$F1,$01,$31], PORTB
LOOKUP B,[$F7,$FB,$FD,$FE],PORTC
PAUSE F
PORTC = $FF
NEXT B
PAUSE F
GOTO LOOP ' DISPLAY FOREVER


The First Lookup To Grab The Digit And Convert It To Segments
The Next Lookup Grabs Digit Placement
Placement Works Briliantly Over The Eight Digits But Am Unable To
Grab The Individual Digits
Could Someone Please Point Out The Obvious For Me?
Thanks!!

I guess, there is a variable named "A", but now shown in your code here.

So in the second FOR LOOP, there should be "N = A Dig B".

But, even then, I did not understand what you meant by individual digits? individual digits of which variable? Can you be more specific and give example?


Also, I have some modifications and suggestions as below. I removed some parts to make it work faster and seem easier to understand.



A VAR BYTE 'this was not listed!
E VAR BYTE
F VAR BYTE
N VAR BYTE
D VAR BYTE
S VAR BYTE
B VAR BYTE
T VAR BYTE



Loop1: '8 Digits To Display T & A


For E = 0 To 3

Pause F 'display T =1234

Lookup T DIG E,[$41,$f3,$49,$61,$33,$25,$05,$f1,$01,$31], PORTB '0-9

Lookup E,[$ef,$df,$bf,$7f], PORTC 'set Digit

Pause F

PORTC = $ff

Next E


For B = 0 To 3
Pause F 'display A =5678

Lookup A DIG B,[$41,$f3,$49,$61,$33,$25,$05,$f1,$01,$31],PORTB

Lookup B,[$f7,$fb,$fd,$fe],PORTC

Pause F

PORTC = $ff

Next B

Pause F

Goto Loop1 ' Display Forever





Edit: 'Also, if you store these numbers in EEPROM, then you can just use the following.
' could work even faster, and use less code space.

'Example: READ T DIG E, PORTB

FOUNDIT! FOUNDIT!

I was trying to disassemble a byte instead of a word !

Requalified var A as a word and all is now well.

Thank all for their help.

Sometimes it takes a second set of eyes.
