TouchGFX: Using FreeRTOS vs No RTOS

[KMew]

Hello,

I am working on a TouchGFX project and one of my goals is to minimize the RAM usage while still maintaining complete functionality of my system, which has some things running at the same time:

• TouchGFX (LTDC - RGB565) - Current using FreeRTOS Task
• BLE (Using BLUENRG-M0L) - Currently using FreeRTOS Task
• Multiple GPIO Interrupts
• Multiple PWM signals generated (with Interrupts)

I am trying to decide if the FreeRTOS is necessary or if I can eliminate it, since the ucHeap for the tasks is relatively large (~34.53 KB).

How do I determine if the FreeRTOS is beneficial or just wasted RAM usage/processing? What thoughts should I have in mind?

I'm working on something quite similar in specs. RTOS makes everything so easy. Trying to use a superloop is possible with flags, but tends to get messy. I'd stick with the RTOS.
