Raspberry Pi3 drive Oled ssh1106 screen

Raspberry Pi3 GPIO interface can be used directly drives the OLED screen

 

First, wiring

According to the Internet just to find the map you can see the Raspberry Pi GPIO pin order Interface 3

PS: 26pin front of the 26-pin GPIO

Pin Description The OLED screen, as shown in Table can be connected:

Raspberry	YOU ARE
5V	VCC
GND	GND
SCL	SCL
SDA	SDA

 

Second, install the necessary tools

sudo apt-get install -y python-smbus

sudo apt-get install -y i2c-tools

After the installation is complete, run sudo raspi-config, will enable I2C interface

run

Sudo i2cdetect -and 1

If you have marked at 0x3c, then the I2C start successfully

 

Third, coded display

Raspberry python driver oled screen needs luna.oled library, can be installed directly pip

Code:

 

from luma.core.interface.serial import i2c
from luma.oled.device import sh1106
from luma.core.render import canvas
from PIL import ImageFont
import time


def stats(oled):
    font = ImageFont.load_default()
    with canvas(oled) as draw:
        localtime = time.strftime("%Y-%m-%d %H:%M:%S", time.localtime())
        draw.text((2, 5), localtime, font=font, fill=255)


def main():
    serial = i2c(port=1, address=0x3C)
    oled = sh1106(serial)
    while True:
        stats (OLED)
        time.sleep(1)


if __name__ == "__main__":
    main()
