Add Adafruit TFT Experiment (rev A)
There will be a revision but get the basics in for now. This successfully displays on a TL040HDS20-B1502A screen with: ``` import board from framebufferio import FramebufferDisplay from dotclockframebuffer import DotClockFramebuffer from displayio import release_displays tft_pins = board.TFT tft_timings = { "frequency": 6_500_000, "width": 720, "height": 720, "hsync_pulse_width": 20, "hsync_front_porch": 40, "hsync_back_porch": 40, "vsync_pulse_width": 10, "vsync_front_porch": 40, "vsync_back_porch": 40, "hsync_idle_low": False, "vsync_idle_low": False, "de_idle_high": False, "pclk_active_high": False, "pclk_idle_high": False, } release_displays() fb = DotClockFramebuffer(**tft_pins, **tft_timings) disp = FramebufferDisplay(fb) ```
