[作品提交] 【Follow me第二季第1期】自选任务 ：SH1107 OLDE屏幕使用

任务理解

在下单阶段，差额部分下单了M5的SH1107

因为CPX没有显示模块，让传感器的读值可以更直观

代码部分

import board
import displayio
import terminalio
from adafruit_display_text import label
import adafruit_displayio_sh1107
import gc
import os
import busio
import random
import time
import analogio
import adafruit_thermistor

gc.enable()

# release any currently configured displays
displayio.release_displays()


# Setup I2C
i2c = busio.I2C(board.SCL, board.SDA)  # uses board.SCL and board.SDA
display_bus = displayio.I2CDisplay(i2c, device_address=0x3C)


# SH1107 is vertically oriented 64x128
WIDTH = 128
HEIGHT = 64

display = adafruit_displayio_sh1107.SH1107(
    display_bus, width=WIDTH, height=HEIGHT, rotation=0
)

splash = displayio.Group()
display.root_group = splash

default_text = " "*7
text_area = label.Label(terminalio.FONT, text=default_text, scale=2, color=0xFFFFFF, x=0, y=10)

display.root_group =text_area

sensor_light = analogio.AnalogIn(board.LIGHT)
sensor_temp = adafruit_thermistor.Thermistor(board.TEMPERATURE, 10000, 10000, 25, 3950)

while True:
    gc.collect()
    print('mem_free',gc.mem_free())
    temp_value = str(round(sensor_temp.temperature,1))
    light_value = str(sensor_light.value)
    show_value = temp_value + '/' + light_value
    # show_value = 'T/L' + '\n' + show_value
    text_new= show_value
    text_area.text = text_new
    time.sleep(1)

主要逻辑

1. 主要部分是传感器读取，细节请参考

2. 头部需要 在lib文件夹中引入 adafruit_display_text 和 adafruit_displayio_sh1107

3. Line 33~42 主要实例化 显示部分，最后在大循环中定时把传感器的值跟新到显示区域的text

展示

sh1107显示模块，估计只有你多买了一个显示模块
