A minimal MicroPython driver module for ST7735 TFT SPI display that can blit bytearray and nothing more.
Based from Boochow's ST7735 Driver derived from Guy Carver's Original ST7735 Driver
-
Blit RGB565 bytearray (optionally from FrameBuffer) to display.
-
Initialize ST7735 TFT SPI display driver with rotation, RGB/BGR, and color inversion.
-
Red and green tab is supported (WIP).
from framebuf import FrameBuffer, RGB565
from machine import Pin, SPI
from ST7735 import TFT
w = 128
h = 160
tft=TFT(
SPI(
1,
baudrate=2 * 10_000_000,
sck=Pin(18),
mosi=Pin(23),
),
dc=Pin(12),
rst=Pin(13),
cs=Pin(14),
w=w,
h=h,
)
tft.init("R") # "R" or "G"
tft.rotation = 0 # 0=up, 1=left, 2=down, 3=right
tft.is_rgb = True # True=RGB, False=BGR
ba = bytearray(w * h * 2)
fb = FrameBuffer(ba, w, h, RGB565)
fb.fill(0xFFFF)
fb.text("Hi, all!", 32, 64, 0x0000)
tft.blit(0, 0, w, h, ba) # Blit- Better initialization support for other tab type
- Implement RussHughes dynamic initialization
