lookup2 not counting all table. who can help?
is there any way to devide into wo parts?
or is there any way that count goes until sutain figure and then start counting backward?

Freq var word
say var byte
countera var word

loop:

If PORTB.7 =0 THEN
CounterA = 0

Tried this one not working

**emilhs** · - 7th May 2009, 23:08

is there any way to devide one table into two parts and count one part and then the second one?

In the short answer Yes sort of.
something like

Code:

counterA = counterA + 1

The limitation of 85 values only applies to the LOOKUP2 statement.

The plain old LOOKUP can have up to 255.

Remove the 2, and your there.

I didn't know about that limitation Darrel, Thank You.
EDIT: it's in the book alright! It also takes up 3 times the space as lookup.

**emilhs** · - 8th May 2009, 01:03

in my table only 142 figures.
I have to use one of pic18cXX controllers

**Darrel Taylor** · - 8th May 2009, 01:19

You don't need an 18?.

The LOOKUP statement .. NOT the LOOKUP2, will do exactly what you want, even if it's a 12F.
<br>

**emilhs** · - 8th May 2009, 01:24

but at the moment I use 16f84

**emilhs** · - 8th May 2009, 01:26

Is there any way to save count. I mean when you unpress button the count stops and when you press again the count starts from the moment it stoped before?

**emilhs** · - 8th May 2009, 01:30

it gives warning [202] argument out of range Least significant bits used

**mister_e** · - 8th May 2009, 01:42

from the manual

Code:

The LOOKUP statement can be used to retrieve values from a table of 8-bit constants.

8 bits = byte, max value = 255
so you need to use 2 LOOKUP2 table

split your lookup table in two, duplicate your code and your ready to go.

**Darrel Taylor** · - 8th May 2009, 01:52

Yup, your right!

LOOKUP only works with byte sized values. Woops.

Time for a vacation. cyaz
<br>

**emilhs** · - 8th May 2009, 02:23

how make simple count from 902 to 232 with step -10 and back if button is pressed?

**emilhs** · - 8th May 2009, 13:15

is there any way to save count? I mean if button pressed counter is counting the figures from table if button unpressed i want it to be saved some where and when button is pressed for second time i want the counting continue from the figure it stopped is it possible?

can you show me the sample please?

Perhaps something like this ...

      For countera = 0 to 70                ; Siren UP
          Gosub PlayTone
          if PlayButton = 1 then ButtonUp
      Next countera 

      For countera = 69 to 1 step -1        ; Siren Down
          Gosub PlayTone
          if PlayButton = 1 then ButtonUp
      Next countera 
    endif
 ButtonUp:
    Pause 50  
goto loop 

PlayTone:
