STM32 MCUs TouchGFX and GUI

TouchGFX: Undefined reference issues with HAL_UART_Init and HAL_RTC_Init with self-generated code by the cubeMX. How do I fix it? I have included hal_uart.h and enabled UART and USART in conf.h. Nothing seems to work...

High Priority freertos task stops running a soon as touchgfx starts

Hi,I've encountered a strange problem.I have two High Priority tasks and the touchGFX task set to Normal Priority.Both High priority tasks are wakeup, check if a variable and go to sleep with osDelay(10).The tasks do not return from osDelay after a t...

I am working on a project related to printer design. however, I can't figure out certain functions can run on touch gfx or not. I have explained in detail the desired work. So that I could know whether ican implement this project through touch gfx or not.

I have attached a sample video, in which my desired work is being implemented.implemented in the sample video.As you can see the user can increase or decrease the text and can change the height and width at runtime as he wants.Can we implement simila...

The STM32L4R9 Discovery kit it comes with a small round (390x390) DSI based display. I am trying to setup a standard rectangular DSI based display. All the example projects for STM32L4R9xx use a round display using GFXMMU look-up table ...

Since I don't have a round display, I don't need this lookup table to convert the bit locations, but there is no obvious way to not use it. How do you bypass this GFXMMU look-up table method and just send the raw image array to the DSI path? I am usi...
