MicroPython SSD1327
A MicroPython library for SSD1327 128x128 4-bit greyscale OLED displays, over I2C.
For example, the Grove - OLED Display 1.12" which features a 96x96 display.
Example
Copy the file to your device, using ampy, webrepl or compiling and deploying. eg.
$ ampy put ssd1327.pyHello World
import ssd1327
# using Software I2C
from machine import SoftI2C, Pin
i2c = SoftI2C(sda=Pin(21), scl=Pin(22)) # TinyPICO
# i2c = SoftI2C(sda=Pin(0), scl=Pin(1)) # Raspberry Pi Pico
# i2c = SoftI2C(sda=Pin(4), scl=Pin(5)) # WeMos D1 Mini
# or using Hardware I2C
from machine import I2C, Pin
i2c = I2C(0) # TinyPICO sda=19, scl=18
display = ssd1327.SEEED_OLED_96X96(i2c) # Grove OLED Display
# display = ssd1327.SSD1327_I2C(128, 128, i2c) # WaveShare, Zio Qwiic
display.text('Hello World', 0, 0, 255)
display.show()
display.fill(0)
for y in range(0,12):
display.text('Hello World', 0, y * 8, 15 - y)
display.show()See /examples for more.
