Define Panels with multiple Touch input device

[jgauchia]

Hi! I've a question. (Maybe I don't know how to do it)

It's possible to define panels (TFT) with different touch input devices? This is. I need to define TFT but I need to define the touch controller separately.

Thank you

hi,

do you mean a second touch controller (if so, please specify the geometry) or just a single touch controller running from a different driver ?

sorry, my english isn't good.

I mean one tft driver definition only and for the touch controller another one. that is... an example

Driver ILI9488 only definition of panel (SPI , Parallel ... etc..) Touch: (for example)

• XPT2046 another include for definition
• FT6236 the same

The goal is define the TFT panel with one include and the input part (touch, etc,..) in other because there are many types of them

if you wish to support multiple touch devices in your project, but only need to enable one of them (no concurrency), then you can try this:

#define USE_XPT2046 true
#define USE_FT5x06 false

class LGFX : public lgfx::LGFX_Device
{
  lgfx::Bus_SPI       _bus_instance;
  lgfx::Panel_ILI9499 _panel_instance;

  lgfx::Touch_FT5x06  _touch_instance_FT5x06; 
  lgfx::Touch_XPT2046 _touch_instance_XPT2046; 

  public:
    LGFX(void)
    {

      // (... ) bus and panel config block

      // (...) FT6236 config block without  _panel_instance.setTouch()

      // (...) XPT2046 config block without  _panel_instance.setTouch()

      if( USE_XPT2046 ) 
        _panel_instance.setTouch(&_touch_instance_XPT2046 );  
      else if( USE_FT5x06 ) 
        _panel_instance.setTouch(&_touch_instance_FT5x06);

      setPanel(&_panel_instance);
    }
};
