Raspberry Pi3驱动Oled ssh1106屏

Raspberry Pi3可以直接使用GPIO接口驱动OLED屏

一、接线

根据网上随便找的图可以看到树莓派3的GPIO接口引脚顺序

PS:26pin的GPIO为前26针

根据OLED屏的引脚说明，如表连接即可：

树莓	OLED
5V	VCC
GND	GND
SCL	SCL
SDA	SDA

二、安装必要工具

sudo apt-get install -y python-smbus

sudo apt-get install -y i2c-tools

安装完成后，运行sudo raspi-config，将I2C接口启用

运行

sudo i2cdetect -y 1

如果在0x3c处有标记，则说明I2C启动成功

三、编码显示

树莓python驱动oled屏需要luma.oled库，直接pip安装即可

代码：

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()
