We have a string which is to be displayed on a 240x240 LCD, if the string is large than display size then the remaining text will automatically move to the next line.

Hi Group, I'm setting up the stm32h747i-disco (Joystick) by setting ports GPIOK - PK2,PK3,PK4,PK5 and PK6 respectively to inputs with no pull ups/downs. In Touch GFX, I'm calling a virtual function to signal when the selected direction goes low.

The voltage measured was approximately 3.3v at the pins of the joystick. As the direction changes the voltage drops to 0vs. I'm yet to work with the task and I understand that all inputs on the GPIO pins are set to analog by default. My question is, ...

Why alignment and font is combined to translations?

Why touchgfx combines alignment and font with translations?We have same translation in many fonts and alignments, and we must create new Resource for each. Does not seem to make sense. Am I missing something?We end up with a lot of duplicates of the ...
