RA6963 controller

[hosseinildar]

Dear All,
I working with the software and my MCU is STM32F407VG , graghic controller RA6963 and no problem but for refresh and update new data on LCD I've a problem.
I used Draw(&Screen) but the command first clear all of the screen and then update new data. this is a problem because screen winking and flush.
is it another method for refresh screen data?

Hi,

Their are two ways to redraw the data.


1) First method
-Store old data in a variable.
-Set the font color to the color of the background.
-Draw the previously stored text.
-Again set the font color.
-And draw new data

2) Second method
-Draw a rectangular shape around the data.
-Every time you redraw the display firstly redraw the rectangular shape.

Best Regards,

Hi,

Here is the sample code for updating the label.

Code: Select all

void updateLabel(TLabel *lbl, char *str){
  Glcd_Set_Font_Adv(lbl->FontName, 0, _GLCD_HORIZONTAL);
  Glcd_Write_Text_Adv(lbl->Caption, lbl->Left, lbl->Top);
  strcpy(lbl->Caption, str);
  DrawLabel(lbl);
}

Dear Dusan,
Thanks. I tested your example code on the MCU but no change on the LCD.
when I use the code before Draw(&Screen) again the LCD is in Flush.
when I don't Draw(&Screen) the Label data without clear last data overwrite and Label data is black finally.

Hi,

The text on the top right corner of the number needs to be cleared first before redrawing it the first time.
Redraw the text in the top right corner with empty spaces.

Very thanks.

Hi,

The same code can be used that is used to update the label. Except you would just put white spaces instead of text.

Code: Select all

updateLabel(your_labe_name, "    ");
