how does one even start interfacing the screen. i think it's an ILI 9341, and the board is an STMF407VET6

i have tried numerous libraries to no avail. and since it's a blackboard, it's a struggle to find even a single documentation. the screen is to go directly on top of the stm using parallel connection. but when i plug it in, the stm will immediately turn off. do i need a separate power source to power up the screen or something is damaged internally causing some short? (i just started stm less than a month. so i am really a newbie here)
