Nokia lcd include , small footprint to suit pic16's

[astanapane]

Thanks for any help.

please try to be gentle. Life is small and there are lots of good people out there.

Have a nice day.

Good day to all.

I have two questions. One is related to this amazing library shared by Richard and the other one is related to a small project i have.

1. May i add a picture to nokia LCD via the usercommand LCDDAT?

For image data could i use the GLCD from Miktoelektronics?

;##################################################################
 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

2. Im working with some speed values. So range can be from 0 to infinity.

How could i catch/retreive the highest value from a Variable? Is there any specific way - path to do that?

thanks.

Can you define infinity please?

Your variables can be: bit (0-1), bytes (0-255), word (0-65535) and long (-2147483648 to 2147483647)

Hi Ioanni, thanks for the reply.

Speed is not going to exceed any value more than a logical speed targeting to a bicycle or a car. In that case as i understand we could use "word" variable.

But there is no specific value as a limit. It can be any possible number that a variable may have.

thanks in advance.

Maybe the MAX operator can do what you want.

Your check loop can be something like this:

max_value = old_speed MAX speed

old_speed = max_value

But this will lead eventually to a top value on max_value and you may have to reset this value. Don't know what you try to accomplish but a periodic reset may be needed.

Thanks Ioanni,

i will try the MAX operator.

What i'm trying to export is the maximum speed value of a single run.

As i'm not in my home computer right now i will try your advice later today.

Many thanks.

i did look at the array generated by Mikroelektronics glcd bitmap generator and
it seems i rejected it for that generated by lcdassistant, cannot recall why.
none of my posted examples use mokroe files . they would all need a bit of
work to leverage into pbp anyway

1. May i add a picture to nokia LCD via the usercommand LCDDAT?

the LCDDAT sends 1 byte to the lcd @ the current cursor posn
it would not be the most efficient way to upload an image.
i saw no way to read pixel data back from the display so i decided that the only way to
create a decent bitmapped image function was using a frame buffer. this i have implemented
in the c version as posted.
implementing this function in pbb is not something i'm willing to invest the time into
