It comes with either Segger emWin or TouchGFX, depending on the code you upload or the default firmware on the board, which may vary based on the manufacturing date of the evaluation board.
RTOS is important in embedded devices that use a GUI, since driving a display takes time, and it's essential to prioritize the display update cycle—whether it's actively interacting with the user or remaining idle.
With an RTOS, it's easier to schedule tasks to run at specific time intervals.
I've read your posts :) I guess you're just beginning your biggest adventure in the world of embedded systems. These topics can be a bit complex at first, so it's best to start with the basics and get familiar with the STM32 MCU family.
Begin with fundamental peripherals like GPIO (LED toggling), ADC readings, DMA, UART, and timers. Once you're comfortable with those, you can move on to more advanced topics like RTOS and GUI development.
When learning RTOS, focus on understanding the core philosophy behind real-time operating systems rather than just diving into FreeRTOS or any specific RTOS. Most of them are based on the same principles.
GUI development and driving TFT displays are also complex topics. Evaluation boards are primarily meant to showcase the capabilities of the promoted MCU. The example/demo codes provided often lack explanations and are not designed for teaching—they're just demonstrations.
If you try to start with complex topics right away, you'll likely get lost in the example code. Take it step by step.
