pi pico <-> ft232h

GPIO2 -> CLKOUT

GPIO3 -> RXF#

GPIO4 -> TXE#

GPIO5 -> OE#

GPIO6 -> RD#

GPIO7 -> WR#

GPIO8 -> BIT0

3v3 + 3.3v -> ili9341 VCC -> LED ( this is for the lcd back light will be only be labled as led ) needs 3v3 volts from both the chips to balance current draw.

pi pico -> ili9341

Sending data which is emiting from pc through ft232h into pi pico with the help of PIO state machine

(PC + FT232H) -> Pi Pico
