Nokia lcd include , small footprint to suit pic16's

[richard]

have you read the pbp manual and understood the syntax for
Output Modifiers for Formatting Strings using arraywrite ?

its all there

Hi Richard,

my fault, yes i have read the arraywrite - arrayread command and corrected the code in my previous edited message.

Many thanks.

[astanapane]

i have a question regarding the library and the code for the nokia 3310.

for the following code:

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

VAR1 is a byte and VAR2 is a byte as well. Those two numbers are presenting the Speed in format VAR1,VAR2 (where VAR1 can be any number from 0 to infinity, and VAR2 can be any number from 0 to 99)

In case that the VAR1 gets the variable from 0 to =<255 the it can be used as a byte.

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?

If i set speed (VAR1 VAR2) as word then the following command

LCDSTR x,y, speed

does not accept word.

Could you please help me to get the speed as an integer and read it as it is.

For my program i'm testing:

if speed is > 5086 then limit ; 50,86

thanks once again.

i will start here

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.

[richard]

i sent the command like:
Code:
ARRAYWRITE speed [dec var1,dec2 var2,0]
having that it was not possible to use speed as word.

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.
