DC = 22

# 128x32 display with hardware I2C:

# disp = Adafruit_SSD1306.SSD1306_128_32(rst=RST)

 

# 128x64 display with hardware I2C:

# disp = Adafruit_SSD1306.SSD1306_128_64(rst=RST)

 

# Note you can change the I2C address by passing an i2c_address parameter like:

# disp = Adafruit_SSD1306.SSD1306_128_64(rst=RST, i2c_address=0x3C)

 

# Alternatively you can specify an explicit I2C bus number, for example

# with the 128x32 display you would use:

# disp = Adafruit_SSD1306.SSD1306_128_32(rst=RST, i2c_bus=2)

 

# 128x32 display with hardware SPI:

# disp = Adafruit_SSD1306.SSD1306_128_32(rst=RST, dc=DC, spi=SPI.SpiDev(SPI_PORT, SPI_DEVICE, max_speed_hz=8000000))

# disp = Adafruit_SSD1306.SSD1306_128_64(rst=RST, dc=DC, spi=SPI.SpiDev(SPI_PORT, SPI_DEVICE, max_speed_hz=8000000))

 

# Alternatively you can specify a software SPI implementation by providing

# digital GPIO pin numbers for all the required display pins.  For example

# on a Raspberry Pi with the 128x32 display you might use:
