Hello,
unfortunately, there is no easy answer to this question.
Due to the fact that you want to use a completely different hardware with a new display and including touch - it will be more or less a new hardware bring-up. Let me refer to the section Working with your own display which contains some general hints. So far we have not used the ILI9844 - so I cannot provide you a ready-to-use display driver for that.
Best regards,
Manfred.
