Nokia lcd include , small footprint to suit pic16's

[richard]

i will start here

My problem is that i need this floating number for ex. speed = 50,86 to get it as an integer speed = 5086. May i have your help please?

you do it exactly the same way as for a lcd display

buff var byte[6] ; 4dig+dp+null
speed var word
ARRAYWRITE buff,[dec2 speed/100,".",dec2 speed//100 ,0]
LCDSTR x,y, buff

LCDSTR x,y, speed
does not accept word.

correct lcdstr str buffer var ,const str

from the inc file

;################################################# #################
USERCOMMAND "LCDC" ;X,Y,CHR 0 < X < 84 , 0 < Y < 7 , 31 < CHR > 127
USERCOMMAND "LCDCLR" ;clear LCD
USERCOMMAND "LCDSTR" ;STRING @ X,Y or Constant String
USERCOMMAND "LCDCMD" ;cmd BYTE TO LCD
USERCOMMAND "LCDDAT" ;DATA BYTE TO LCD

i might preempt the next question
leading zero's and right justifying fields

im not in front of the circuit and computer in order to test it.

i havent done it as it following /100 and //100 (remainder)

buff var byte[6] ; 4dig+dp+nullspeed 
var word
ARRAYWRITE buff,[dec2 speed/100,"."dec2 speed//100 ,0]
LCDSTR x,y, buff

I have used it with "." like the following in the loop and i get it right on the LCD as 50,86 for example. :

I need on the screen the right "floating" value.

ARRAYWRITE speed [dec var1,".",dec2 var2,0]
LCDSTR x,y, speed

then i send the code to sub label

speedlimit:
and i havent used "."

i sent the command like:

ARRAYWRITE speed [dec var1,dec2 var2,0]

having that it was not possible to use speed as word.

i sent the command like:

ARRAYWRITE speed [dec var1,dec2 var2,0]

makes no sense to me

ARRAYWRITE speed

speed must be an existing chr array big enough to contain the text generated plus a null terminator
a word var could hold only 1 chr safely ,since pbp checks nothing anything could get clobbered by misuse like that

[astanapane]

now it makes sense why i was getting some messy chr on the screen like that.

i've tried the following but didnt work.

rbuf  var byte
wbuf var word

checkt: 
arraywrite RBUF,[DEC2 speed1/100,DEC2 speed2//100,0] ; for example speed1 = 56 and speed2 is 85
LCDSTR 0,2, RBUF ; ----------> this gives 0085
wbuf = rbuf                                 
if wBUF > 5685 then 
gosub limit
return

then i tried:

checkt: 
arraywrite RBUF,[DEC speed1,DEC2 speed2//100,0] ; for example speed1 = 56 and speed2 is 85
LCDSTR 0,2, RBUF ; ----------> this gives 5685 which is what i want....BUT!!!! when i try to check if wbuf > than 5685, it doesnt work
wbuf = rbuf                                 
if wBUF > 5685 then   ' IF THE TEMPC IS GREATER THAN 37 C THEN LIGHT UP THE BLUE LED
high lata.0
ELSE
low lata.0
endif
return

how is it possible to combine those two speed1 and speed2 vars in one var? and check then the result as an integer number?

You have only declared "rbuf var byte" It is being used as a pointer as far as I can see. It will be NO LARGER than 255.

Hi dave,

i solved it.

i used the rbuf as var word

Then i didnt add the commands for

arraywrite rbuf,[dec speed1,dec2 speed2,0]

i used the above command only to combine it with the following and present the number to the lcd.

So the solutions for me is:

checkt:
RBUF = (SPEED1*100) + SPEED2
IF RBUF > 5682 THEN ; THIS IS JUST AN EXAMPLE
GOSUB LIMIT
RETURN

Thanks a lot for the help all of you.
