SSD1306

Modified SSD1306 driver from micropython

Added hardware horizontal scroll and a clear function

Heres a usage example:

# runs under micropython version 1.20
# Tested using a cheap ESP32 module

from machine import Pin, I2C
import time
import ssd1306

def lcdInit():
    # set up default hardware I2C
    i2c = I2C(0)                                       # default hardware scl=Pin(18), sda=Pin(19)
    lcd = ssd1306.SSD1306_I2C(128, 32, i2c)            # my lcd is 128x32
    return lcd

def main():

    display = lcdInit()
    display.clear()

    while True:

        display.text("Hello World", 0, 0, 1)
        display.show()
        
        # scroll right
        display.hw_scroll_h()

        time.sleep(3)

        # scroll left
        display.hw_scroll_h(False)

        time.sleep(3)

        display.hw_scroll_off()
        time.sleep(3)
        display.clear()
        time.sleep(1)
