Will this work on raspberry pi os

[Abhi895]

Hi so I am working on this project and i was just wondering if this will work on a raspberry pi 3a+ which is the one that I am using, this doesn't support pitft os, so I have had to install raspberry pi os and use hdmi mirroring to get the image onto the pitft. Will using raspberry pi os rather than pitft os, affect the operating system in anyway, and will I still be able to make and use this phone in the same way. Thank you
