t6963 display problem in displaying integers

[Naveen11]

Hi i am using mikroc pro for pic t6963 glcd library to display a set 16 integers as in table as rows and columns, i have used same method to display these variables in the display where i require in (x,y ) positions... mostly all numbers displays correctly , but certain numbers appears as symbols and characters , what is the reason...

controller used pic18f87k90

all variables are declared as
unsigned int Pulse_PickA,Pulse_PickB,Pulse_PickC,Pulse_PickD.
unsigned int Picks4inchA,Picks4inchB,Picks4inchC,Picks4inchD

like these 16 integers . out of 16 , 2 or 3 integers diaplay as symbols or numbers , in ram memory the value is correct as i expect but while displaying alone its not perfect . should i change the way i display this function... please give ur suggetions.

Hi,

Is it always the same variables that are showing the symbols or does it change overtime?

Regards,

Ivan.

[Naveen11]

it changes der are 16 variables but we cant say this variables causes issues, it changes every time we re program the mcu, but mostly 3 variables gets afftected by this issue and those variables are random..

[Thomas.Pahl@t-online.de]

Perhaps timing problems.

For a test try the following: set the mcu clock frequency (in edit project) to 4 times the mcu really runs and test again.

If that runs, then better write your own library.

hi the problem solved now the change i made was instead of typing the to converts as character i used (0x30 ) , now i have changed it to 48, now the code works fine , can i know its the problem with compiler standard or its problem with my approach towards the way i code?.....
