oled7脚+esp32+micropython温湿度显示到显示屏上

一、接线

1.温湿度传感器：

GND-----------GND
5V------------VCC
P12-----------DATA

2.显示屏（7脚显示屏，ssd1306驱动）

GND-----------GND
3V3/5V--------VCC
P18-----------D0
P23-----------D1
P15-----------RES
P2------------DC
P4------------CS

二、代码

只显示了简单的字，并不是显示温湿度，字模还没搞，做个笔记

import dht
from machine import Pin,SoftSPI
from ssd1306 import SSD1306_SPI
import utime
import time

# 设置oled引脚
dc=Pin(2,Pin.OUT)
res=Pin(15,Pin.OUT)
cs=Pin(4,Pin.OUT)

# 设置DHT传感器连接的引脚
dht_pin = Pin(12, Pin.IN, Pin.PULL_UP)
# 创建DHT对象
dht_sensor = dht.DHT11(dht_pin)

#波特率；输出极性；相位，此处没用到，0和1都可；sck时钟同步信号线D0；mosi主机发送引脚D1；mosi主机接收引脚,此处用不到

oled=SSD1306_SPI(128,64,spi,dc,res,cs)  #创建oled对象

三、效果如图

你可以把元旦这两个字替换掉，这个时间没有联网的默认是2000/01/01开始的
