DebugPrinter Feature available in TouchGFX 4.12.3?

[Marco.R]

Hi

Does anyone know if the DebugPrinter is still available in current version (see Link)?​. I tried to implement it but it looks like LCD16DebugPrinter isn't available anymore.

If it is still available, how can I use it?

Thanks

Marco

I think that in 4.12.3 the DebugPrinter was renamed to LCD24DebugPrinter. It probably was 24bit to begin with (related to the hand-written glyphs being used).

In 4.13.0 we have DebugPrinter support for all LCD drivers. Should be out this december.

Hi @Martin KJELDSEN​

Thank you for the information. In that case I'll wait for the next release.

I ran across DebugPrinter yesterday and was wondering about how to implement it as well.

Thanks for providing the link you did.

Martin, are are there an example that utilizes it?

I did get something to compile and work (somewhat). Things have changed since the TouchGFX Tips and Tricks in the link you provided.

FrontendApplication.cpp:

#include <gui/common/FrontendApplication.hpp>
#include <platform/driver/lcd/LCD24bpp.hpp>
LCD24DebugPrinter lcd24bppDebugPrinter;
 
FrontendApplication::FrontendApplication(Model& m, FrontendHeap& heap)
 : FrontendApplicationBase(m, heap)
{
	lcd24bppDebugPrinter.setDebugPosition(0, 0, 240, 40);
	lcd24bppDebugPrinter.setDebugScale(2);
	lcd24bppDebugPrinter.setDebugColor(0x00); //black
	Application::setDebugPrinter(&lcd24bppDebugPrinter);
}

Then when implementing it in a Screen1View.cpp, calling the following function works except not invalidated on the screen correctly.

Unicode::UnicodeChar debugStringBuffer[30];
 
void Screen1View::updateDebugString()
{
 static int count = 0;
 count++;
 Unicode::snprintf(debugStringBuffer, sizeof(debugStringBuffer), "%d", count);
 Application::getDebugPrinter()->setDebugString((const char*)debugStringBuffer);
 // touchgfx::Application::invalidateDebugRegion();
}

I needed to comment out the call to invalidateDebugRegion() because it is no longer a valid function.

I tried to call invalidateArea(), but is a protected function.
