Introduction

DisplayIO driver for SH1107 monochrome displays. DisplayIO drivers enable terminal output. This driver depends on a future (TBD) quirk added to DisplayIO.

Dependencies

This driver depends on:

• Adafruit CircuitPython Version 6+ A new quirk in 6.0 for SH1107
• Adafruit SH1107 128 x 64 OLED display, used for testing.

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.

Usage Example (see example for more)

import board
import displayio
import terminalio
import bitmap_label as label # from adafruit_display_text
import mdroberts1243_displayio_sh1107

displayio.release_displays()
#oled_reset = board.D9

# Use for I2C
i2c = board.I2C()
display_bus = displayio.I2CDisplay(i2c, device_address=0x3C)

# SH1107 is vertically oriented 64x128
WIDTH = 128
HEIGHT = 64
BORDER = 2

display = mdroberts1243_displayio_sh1107.SH1107(display_bus, width=WIDTH, height=HEIGHT)

# Make the display context
splash = displayio.Group(max_size=10)
display.show(splash)

color_bitmap = displayio.Bitmap(WIDTH, HEIGHT, 1)
color_palette = displayio.Palette(1)
color_palette[0] = 0xFFFFFF  # White

bg_sprite = displayio.TileGrid(color_bitmap, pixel_shader=color_palette, x=0, y=0)
splash.append(bg_sprite)

# Draw a smaller inner rectangle in black
inner_bitmap = displayio.Bitmap(WIDTH - BORDER * 2, HEIGHT - BORDER * 2, 1)
inner_palette = displayio.Palette(1)
inner_palette[0] = 0x000000  # Black
inner_sprite = displayio.TileGrid(inner_bitmap, pixel_shader=inner_palette, x=BORDER, y=BORDER)
splash.append(inner_sprite)
