Hi,I am using TouchGFX with a STM32F4 MCU that is working pretty great and is quite awesome :)!I am running into an issue where when transitioning (cover transition) from one screen to the other, the upper part of the screen is flickering the lower p...

Hi Sir,Thank you so much for your detailed answer.Indeed, I have been able to check this using the debug pins of TouchGFX. When transitioning from one screen to the other, the rendering time (MCU frame rate) goes down to 50-53Hz while my screen is...

Hi Both and thank you for your support!So while the CPU is in reset, I do have a nice 3.3V. After releasing the reset button, I do observe a 1.8V drop. But it is hard to tell when it occurs.I agree with you, I do not see any configuration that would ...

Hi,Yes same thing with the pull-up resistor, I measure 1.7V - 1.8V while I should be measuring 3.3V.The power supply voltage is still 3.3V.I think but I can't be sure, that the voltage is dropping when the 1st interrupt occurs on the Exti Line 2.I do...
