Hi,
I am using an SAB80C537 µC and a display with HD44780 driver. The display software works properly for the text outputs. But I can not output the variables. The subfunction for the variable output on the Display is given below;


Impuls = 3; //A Current Value as an example
void display_Var(UInt Impuls)
{

P5 = Impuls; //Data bus
Delay(); //Wait Modus
LCD_RS = 1;
LCD_R_W = 0;
LCD_ENB = 1;
LCD_ENB = 0;
}


But I see only a black box on the display in spite of the Number "3". The µC converts this variable to a !textcode! so that it can not interpret it.
Which changes should I do to output variables?
Regards
