In the short answer Yes sort of.
something like

Code:

repeat counterA = counterA + 1 LOOKUP2 CounterA,[902,902,902,884,884,884,851,851,835,820,820,806,806,792,778,765,_ 752,740,740,716,716,705,705,683,683,653,663,663,644,635,618,627,602,594,578,578,557,_ 564,549,531,531,519,513,501,492,475,465,465,456,442,434,422,414,406,389,389,373,373,_ 352,334,329,318,307,296,283,279,263,252,249,238,232,232,238,249,252,263,279,283,296,_ 307,318,329,334,352,373,373,389,389,406,414,422,434,442,456,465,465,475,492,501,_ 513,519,531,531,549,564,557,578,578,594,602,627,618,635,644,663,663,653,683,683,_ 705,705,716,716,740,740,752,765,778,792,806,806,820,820,835,851,851,884,884,884,_ 902,902,902],Freq until counterA = 75 repeat counterA = counterA - 1 LOOKUP2 CounterA,[902,902,902,884,884,884,851,851,835,820,820,806,806,792,778,765,_ 752,740,740,716,716,705,705,683,683,653,663,663,644,635,618,627,602,594,578,578,557,_ 564,549,531,531,519,513,501,492,475,465,465,456,442,434,422,414,406,389,389,373,373,_ 352,334,329,318,307,296,283,279,263,252,249,238,232,232,238,249,252,263,279,283,296,_ 307,318,329,334,352,373,373,389,389,406,414,422,434,442,456,465,465,475,492,501,_ 513,519,531,531,549,564,557,578,578,594,602,627,618,635,644,663,663,653,683,683,_ 705,705,716,716,740,740,752,765,778,792,806,806,820,820,835,851,851,884,884,884,_ 902,902,902],Freq until countera = 0

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.

thank you

in my table only 142 figures.
I have to use one of pic18cXX controllers
- 8th May 2009, 01:19
Darrel Taylor

You don't need an 18?.

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

but at the moment I use 16f84

lookup

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?

Lookup did not work

it gives warning [202] argument out of range Least significant bits used
- 8th May 2009, 01:42
mister_e

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.
- 8th May 2009, 01:52
Darrel Taylor

Yup, your right!

LOOKUP only works with byte sized values. Woops. :o
