# MicroPython-ST7735

This is a modified version of [GuyCarver's ST7735.py](https://github.com/GuyCarver/MicroPython/blob/master/lib/ST7735.py) ST7735 TFT LCD driver for MicroPython.

A font file is necessary for displaying text (some font files are in [GuyCarver's repo](https://github.com/GuyCarver/MicroPython/tree/master/lib)).

Text nowrap option added(default: nowrap=False).

`graphicstest.py` is a sample code. I wrote this to make it similar to [Adafruit's graphicstest sketch for Arduino](https://github.com/adafruit/Adafruit-ST7735-Library/tree/master/examples/graphicstest). 

If `graphicstest.py` doesn't work correctly, try replaceing `initr()` at line 8 to `initg()` or `initb()` or `initb2()`. You can also change `rgb(True)` to `rgb(False)` to switch red and blue pixels if your LCD module shows incorrect colors.

Pin connections for ESP32:

LCD |ESP32-DevKitC

----|----

VLED|3V3

RST |IO17

A0  |IO16(DC)

SDA |IO13(MOSI)

SCK |IO14(CLK)

VCC |3V3

CS  |IO18

GND |GND

`tftbmp.py` is another sample similar to [Adafruit's tftbmp sketch for Arduino](https://github.com/adafruit/Adafruit-ST7735-Library/blob/master/examples/spitftbitmap/spitftbitmap.ino).

Place bmp file named `test128x160.bmp` in the file system of MicroPython using file uploading tool such as [ampy](https://github.com/adafruit/ampy), etc.

`offscreen-buffer.py` shows how you can use an offscreen frame buffer which is an instance of FrameBuffer class. I tested this on Raspberry Pi Pico. See https://github.com/boochow/MicroPython-ST7735/issues/9 for the pin connections.
