change screens from HAL_UART_Rxcpltcallback/ hardware button click

[Vdand.11]

i got STM32F401 and ST7735. 1.8inch TFT but NO touch, i am trying to setup two screens and switch between them. so i decided to used physical button over interrupt / UART. i made necessary callbacks and able to alter a flag. now the question is how to link it to touchgfx? where to edit the code.? i have alredy created hardware button clicked event but for some reason its not switching from home screan to screen 2. my call backs are working perfect toogling the LEDs . but the screan is not changing.

Hi,

I often recommend looking at this video from Gustavo explaining how to communicate between the hardware and TouchGFX with the Model-View-Presenter architecture. Instead of turning on and off a led you just call the change screen function. Or is this what you were referring to already by talking about the LED toggling ? Could you share the code in that case on how you call the change screen functions ? Does it work in the simulator ?
