Text display

[Vineyards]

I drag two buttons one of which displays a static text and another to display dynamic data such as ADC measurement result.

Should I use the usual T6963C_Write_Text function to display ADC data on the other button or should I use the Caption_Text commands provided with the tool. Can you give an example showing the best method of displaying measurement results on a caption button using your library.

Hi,

just load example "EasyPIC6_ADC_Demo.vglcd" and choose your programming language.

Then take a look at the file EasyPIC6_ADC_Demo_events_code, procedure Rectangle1Down and you will see the code for ADC label (Label15).

In mikroBasic it looks like this:

Code: Select all

    adc_value = ADC_Get_Sample(3)    ' read analog value from ADC
    IntToStr(adc_value, txt)
    Rtrim(txt)
    Label15_Caption = txt
    DrawLabel(@Label15)

I am trying to get this simple code to work:

Code: Select all

#include "test06_objects.h"

void main() {

  Start_TP();

  while (1) {
    Check_TP();
    Label1_Caption[5]="merha";
    DrawLabel(&label1);
  }

}

I am doing this just to make sure I can display text later on I will add the required ADC code. This however fails. Nothing is displayed.

The compiler is MikroC 4.15 and both programs are registered. What seems to be the problem?

Hi,

In C language this line :

Code: Select all

Label1_Caption[5]="merha";

will write to the array element with index 5.




You should include C_String library and try something like this:

Code: Select all

strcpy(Label1_Caption, "merha");

just like in the ADC example project

Here is the code:

Code: Select all

#include "test06_objects.h"

void main() {
char txt[7];
int raw;
float ph;
porta=0;
trisa=255;
Start_TP();

  while (1) {
   // Check_TP();
    raw=adc_read(0);
    inttostr(raw,txt);
    Rtrim(txt);
  strcpy(Label1_Caption, txt);
  DrawLabel(&Label1);
  }

}

This works OK but when the line Check_TP(); is enabled, the loop stalls and it only displays the value read in the first pass. Could it be expecting a tap on the screen? There aren't any buttons or touchable objects though.

Hi,

Visual Glcd http://www.visualglcd.com is RAD (Rapid Application Development) tool for working with displays and touch panels. Programmer only writes code for Touch Panel events (OnUp, OnDown, OnClick and OnPress).


If you want to use it only for display, then you can/should comment the Touch Panel routines.

Hi milan,

that is the reason, why I made a suggestion in an other thread.

Let us disable the TP-functionality when we don't use a touch panel. I think a checkbox should disable all functions for the TP.

Hi,

your suggestion is already added to the wish list

Thank you for helping us to improve Visual GLCD tool
