displayio driver for ST7735R TFT-LCD displays.
Hardware
=========
* `1.8" SPI TFT display, 160x128 18-bit color
<https://www.adafruit.com/product/618>`_
* `Adafruit 0.96" 160x80 Color TFT Display w/ MicroSD Card Breakout
<https://www.adafruit.com/product/3533>`_
* `1.8" Color TFT LCD display with MicroSD Card Breakout
<https://www.adafruit.com/product/358>`_
* `Adafruit 1.44" Color TFT LCD Display with MicroSD Card breakout
<https://www.adafruit.com/product/2088>`_
* `Adafruit Mini Color TFT with Joystick FeatherWing
<https://www.adafruit.com/product/3321>`_
If you have a board with a ST7735B chip, you may want to try
`the Adafruit ST7735 Driver <https://github.com/adafruit/Adafruit_CircuitPython_ST7735>`_.
Dependencies
=============
This driver depends on:
* `Adafruit CircuitPython 4.0.0-beta.0+ <https://github.com/adafruit/circuitpython>`_
Please ensure all dependencies are available on the CircuitPython filesystem.
This is easily achieved by downloading
`the Adafruit library and driver bundle <https://github.com/adafruit/Adafruit_CircuitPython_Bundle>`_.
Usage Example
=============
.. code-block:: python
import board
import displayio
import fourwire
from adafruit_st7735r import ST7735R
spi = board.SPI()
tft_cs = board.D5
tft_dc = board.D6
displayio.release_displays()
display_bus = fourwire.FourWire(spi, command=tft_dc, chip_select=tft_cs, reset=board.D9)
display = ST7735R(display_bus, width=128, height=128, colstart=2, rowstart=1)
# Make the display context
splash = displayio.Group()
color_bitmap = displayio.Bitmap(128, 128, 1)
color_palette = displayio.Palette(1)
color_palette[0] = 0xFF0000
bg_sprite = displayio.TileGrid(color_bitmap,
pixel_shader=color_palette,
x=0, y=0)
splash.append(bg_sprite)
while True:
pass
