We use the ADV7623 for superimpose textdata on the hd-video (1080p) . Runs perfect, but the
text is very small, so we tried to scale it with TBOX_V_SCALE and TBOX_H_SCALE, without success.
If we want to increase the text size, have we to change the font data??

Another problem occured: when we tried to show a sentence with more than 16 characters, we need to use

 
more "words". But how can we get the information where the first "word" ends to continue with the next one?

Thanks for your help!
Klaus

    Hi,
    
 
    Swap RAM should be done after setting TBOX_V_SCALE and TBOX_H_SCALE value.But the font quality will decreased  when using Horizontal or Vertical scaling value,
    
 
    Hence, More than one font can be used to increase the text size programmatically.
    
 
    We can find the next word (TBOX) location by calculating the offset of the each glyphs.
    
 
    Thanks,

    Hello Poornima
    
 
    Thanks for your fast response. What do you meen with swap RAM?
    I only use the internal memory. 
    
 
    The string RAM is written dynamically ( when new measurement data are received).
    
 
    Then I write the Tbox instr. RAM and set the TBOX enable. Set the TBOX_V_SCALE and TBOX_H_SCALE
    
 
    bits an begin and end of progcode without any change. I only have the small text on OSD.

    
 
    Can you explain how I can scale it in programm code and how's the sequence?
    
 
    Thanks and kind regards

    Hi,  
      Swap RAM is nothing but in Gen2 all the memories are double buffered. After the proper values have been written into the RAM’s, the hardware must be commanded to “swap” the memories during next vsync edge.
    
 
      In order to determine when the swap has finished and the engine is ready to take new commands.
    
 
    Please configure the RAM_SWAP_START register(0x0C),it is used to set the OSD engine to swap the ram at the end of current frame.
    
 
    Please ensure that osd_tbox_scale(0x09) register has configured from TBOX_V_SCALE[7:4] from 4thto7th bit by scaling the tbox with vertical scale factor and also by TBOX_H_SCALE[3:0] from 0thto3rd bit with horizontal scale factor,then only we can able to get the increased text OSD.
    
 
     Are you using character based OSD tool for developing? Please let us know.
    
 
    Thanks,

    Hello Poornima
    
 
    Thanks for your answer. I am sorry but I cant find a register containing RAM_SWAP_START in the
    Software manual Rev.C. Is this an undocumented Register of the ADV7623 ?

    Kind regards

    Hi,
    
 
     Please refer ADV7625 register control manual which is available at ADV7625 Design Support Files .
    
 
     This are all belongs to the same family chip-set,So you can refer here.

    Hello Poornima
    I took the ADV7625 SW manual and compared it with the ADV7623 Manual. The register functions are not similar.
    
 
    Addr. OSD 0x10: ADV7625-->osd_Transparant_colour,  ADV7623--> OSD_Filled_Box_enable
    Have only seen that OSD Addr. 0x09 - 0x0f are not defined.

    Also tried to change reg. OSD(0x0c) like described by you, without any effect.
    
 
    Kind regards

     // Paramter 0 / 1 Datalenght(string + Pointer)
     // Parameter 2 / SPPI command
     OSDPushToSpi(Tx);
     sprintf(Tx,"%c%c%c%c%c%c%c%c",0x06,0x00,0x05,0x06, 0xf0,(UCHAR)(WegLaenge2),((UCHAR)(WegLaenge2) >> 1),0xc0); //-->Tbox instruction RAM
     OSDPushToSpi(Tx);
     HAL_I2CWriteByte(0x48 , 0x80 , 0x40) ; // OSD-MAP(0x48), Reg:OSD TEXT BOX ENABLE_1; enable TB 6,
     HAL_I2CWriteByte(0x48 , 0xa0 , 0x40) ;
    
 
    Displaying the OSD data runs perfect, only the character size should be larger.

    Hi,
    
 
      Could you please share your project,we can verify in our side and let you know the result.
    
 
      By changing the 0x48,0x07 ,0x13 register value as 0x15,we can get the increased vertical scalar as 4x.Please update and check it in your side.
    
 
    Thanks,
    
 
    Poornima

    Hello Poornima
    
 
    Thanks for your reply. I tried to change the value of reg. 0x07, without any success. As you can see on the code below,
    
 
    which shows the value of an incremental counter, I modified the position value. So when the counter increases, not only
    
 
    the shown value changes, but also the position changes in pixel steps. 
    
 
    Now, when the H/V_SCALE value of the register is changed, I can see that the steps in the movement increases,
    
 
    but not the size of the font!!
    
 

    The software is for an atmel XMEGA192A3 
    
 
    The main routine has the following code:
    
 
    // at this position are only XMEGA code for Port initialisation ,...
    
 
    init_ADV7184();
     init_ADV7513();
